1. Required Products
To support government agencies when they need imagery for more than visualization,
EagleView offers an Orthomosaic with accuracy and clarity to support a wide range of
government functions. EagleView has developed and utilizes an innovative workflow
encapsulating flight planning and capture to produce ultra high-resolution mosaics. This
allows users to extract measurements that can serve as the foundation of various GIS and
other applications, including 3-D modeling and change detection.
EagleView captures oblique imagery at angles of 40 to 45 degrees from the north, south,
east, and west to offer a 360-degree view of every property and parcel. Every pixel in
EagleView’s oblique and orthoimagery is georeferenced, giving users the ability to
interact with, measure, and extract data from these actionable images.
Imagery products in scope are listed below. Imagery products are further detailed in
Section 2, Deliverables and Applicable Specifications.
Annual Ortho Capture: 3” and 6” Certified Ortho Imagery
Supplemental Ortho Capture: 3” Frequent Ortho
Oblique Images: 3” and 6” Oblique Imagery ( Annual Capture only)
All imagery products include, but ar e not limited to, data processing, QA/QC,
supporting project management and training, as well as Early Access to imagery,
access to our viewing application, EagleView Cloud, Integration access and our
Disaster Response Program.
EagleView Cloud
EagleView’s web-based application, EagleView Cloud Explorer, allows users to
view, measure, and analyze aerial imagery with precision. It includes various
measurement tools and features an intuitive graphical user interface that enables
users to easily perform on-screen measurements. Individual measurements can
always be removed or edited for improved accuracy. EagleView will support and

assist clients migrating from EagleView’s ConnectExplorer to migrate to Cloud Explorer.
Integrations
EagleView has established integrations with major CAD and most major CAMA
vendors, and is a Gold Partner of good standing in the Esri Partner Network.
EagleView’s CONNECT platform keeps pace with ESRI’s developments, while offering
backward compatibility to older applications, databases, and operating systems.
Further, our platform provides the public unlimited visualization-only access to
EagleView-hosted custom imagery libraries via a web application or server-based
integration, such as the Integrated Pictometry Application (IPA).
The IPA is a robust integration that allows customers and partners to embed an
imagery viewer with EagleView oblique and ortho imagery and tools into their
existing public-facing and internal web applications. CONNECT IPA has been
integrated into hundreds of CAMA, GIS, and E-911 services across the United States
and Canada.
In addition, the platform offers robust integration capabilities and offers standard
APIs that can be leveraged t o integrate with Santa Clara County desired current
and future software applications. These include but are not limited to ArcGIS
products, VertiGIS, and RapidDeploy.
Early Access
We will provide Santa Clara County with expedited delivery of initial aerial imagery. At
no additional cost, you will receive preliminary imagery within 7–14 days post-
capture through CONNECT EarlyAccess. With EarlyAccess, authorized users can login
to EagleView’s software viewing platform, CONNECTExplorer and Cloud Explorer, and
access imagery immediately following preliminary processing and quality control checks
(but prior to final processing). This imagery will remain available until we deliver
final, fully processed imagery.
Technical Support & Training
At no additional cost, we will provide ongoing technical support and on-location training.
Users will learn best practices and how to use and manage our imagery and software
within existing workflows. Our training program has increased the use of imagery and
software throughout our customers’ organizations.

• Validating correct file formats and versions;
• Reviewing all associated metadata records;
• Reviewing 2D footprints and 3D buildings;
• Reviewing all calibration and analytical reports produced by Sanborn.
7. Optional Services
7.1. 2D Building Roofprints Extracted from LiDAR Data
Sanborn will extract the 2D building roofprints from existing lidar data owned by the County of Santa Clara.
Sanborn has developed a process to extract automated 2D building footprints from the lidar data. 2D polygons, or
building footprints, are created automatically by the classified lidar data’s bare earth and building classifications.
These 2D polygons are 80-90% geometrically accurate meaning the automatically extracted building footprints (2D
shapes representing rooftops) are generally close to the true shape and location of buildings on the ground, but
they are not perfect. Specifically:
• Geometrically accurate refers to how well the shape, position, and size of each polygon aligns with the actual
building roof as seen in the real world or in high-resolution imagery.
• 80–90% accuracy means that, on average, 8 to 9 out of every 10 polygons are reasonably correct in terms of
shape and placement, but there may be some deviations or errors—such as slightly incorrect building edges,
missing small extensions, or generalization of roof detail.
This level of accuracy is considered suitable for many GIS applications, but not precise enough for tasks
that require detailed architectural or engineering-grade accuracy.

Page 29 of 39
Board of Supervisors: Sylvia Arenas, Betty Duong, Otto Lee, Susan Ellenberg and Margaret Abe-Koga County Executive: James R. Williams
A building roofprint is defined as a structure on the ground which has a roof. The perimeter outline of a building is
represented as a georeferenced polygon, as seen in aerial imagery.
Structures included:
• Residential, commercial, and industrial structures (including roof over porches and decks
• Trailer homes and offices
• Mobile homes
• Garages, sheds, and other isolated structures
• Greenhouses attached to a roofed structure
• Stadiums
Structures not included:
• Features without a roof and no usable interior or covered volume.
• Motor vehicles, truck trailers, boats, airplanes, etc.
• Tanks and covered reservoirs and pools with temporary covers.
Each enclosed building representation polygon shall contain two “z” (elevation) attributes: Base Height
representing mean sea level and Building Height representing the highest point on the building (building height
above ground), excluding flagpoles, chimneys, and other features smaller than 4 square feet.
Building footprints minimum size must be at least 100 sq ft. Detached buildings must be represented as single
polygons, not merged with other buildings. Note, depending on the density of the buildings there may not be lidar
points between the buildings to automatically separate independent buildings.
Building roofprints will be topologically clean.
Building IDs will be maintained to support change detection activities when necessary.
Deliverable Format:
• GIS compatible format such as File Geodatabase or Shapefile.
• Building 2D Roofprints must be represented as closed polygons with height “z” values as attributes for
each feature.
• Building 2D Roofprints must be delivered as Z-aware feature class.
• Building 2D Roofprints must be delivered as one feature class, not in multiple feature classes.
• FGDC compliant metadata must be provided.
7.1.1 High Accuracy 2D Models:
If higher accuracy and reliability of structures is desired, the vector files can be taken through a manual
editing process to achieve 95% accuracy of the building wireframes.

Board of Supervisors: Sylvia Arenas, Betty Duong, Otto Lee, Susan Ellenberg and Margaret Abe-Koga County Executive: James R. Williams
7.2. 3D Models Extracted from LiDAR Data
Once the 2D footprints (generated from Lidar data) are created and checked for consistency, they are used as
input to create the 3D building wireframe product. The 2D and 3D wireframes can be beneficial for:
• Measuring area of structure
• Solar potential calculation
• Measuring lengths of sides of segments
• Calculating roof repair costs
• Tax-assessment
3D wireframes also stem from an automated process that has 80-90% accuracy levels. The 3D wireframes are
created based on the geometry of the 2D footprints. Each wireframe closely depicts the structures' most natural
features and angles. The software uses exported attributes for the walls and roofs derived from the classified point
cloud to form the final wireframe. The deliverable formats of 3D models will be an ESRI geodatabase or shapefile
formats, based on customer requirements.
The building models generated by this process do not have any textures. Sanborn’s 3D modeling methodology
follows the CityGML specifications, with the addition of texture information. Textures can consist of generic
textures from a library, photo-realistic textures from a ground-based or oblique collection. See 3D web mesh in the
optional section of this proposal.
Building 3D Model should be developed at minimum at Level of Detail 2 (LOD2), where the model should include
the differentiation of major roof structures (e.g., Gable, Hip, Shed, Mansard, Vault, and Dome), in urban area and
LOD1 in rural area.
7.3. Planimetric Mapping
Sanborn has extensive experience extracting planimetric data from aerial imagery and lidar for use in creating or
updating GIS data layers using photogrammetric techniques. Sanborn’s price assumed the below features.
Sanborn will work with the County and/or partner agencies on final SOW, price and database design.
• Contours
o 1-foot interval, 5-foot index
o 5-foot interval, 25-foot index
o 10-foot interval, 50-foot index
o 25-foot interval, 100-ft index
o Deliverables will be one contour dataset and individual feature classes for each contour
interval coding for 1-foot, 5-foot, 10-foot, and 25-foot.
• Water Body
• Tree Canopy/Tree Inventory
o Tree canopy/tree inventory should be raster data and County is interested in Canopy Height,
Canopy Cover (density of vegetation greater than or equal to 10 feet tall), Canopy Bulk Density.
County is open to suggestions and data models.

Board of Supervisors: Sylvia Arenas, Betty Duong, Otto Lee, Susan Ellenberg and Margaret Abe-Koga County Executive: James R. Williams
Dirt and Gravel Roads – Dirt and gravel roads wide enough for a vehicle. Non-ephemeral fire
roads, ranch roads and long driveways.
Dirt and Gravel Area - Dirt and Gravel surfaces that are highly compacted and used by humans
and equipment such as dirt parking lot.
Other Paved – Includes parking lots, sidewalks, paved walking paths, swimming pools, tennis
courts.
• Trails/Alleys

o Path, Paved Edge
o Path, Unpaved Edge
Sanborn will extract the desired planimetric features from the controlled aerial imagery in a 3D
stereoscopic environment, utilizing first-order softcopy workstations operated by photogrammetrists
experienced in photo interpretation to update or create the planimetric database, as appropriate to each
feature class. The use of softcopy workstations utilizing stereo superimposition technology (planimetric
features traced in vector form directly over the top of stereoscopic imagery displayed on the computer
monitor) ensures accurate and complete collection of all mapped features. This approach not only
provides an accurate horizontal position for the planimetric features, but it also provides accurate
elevation data where needed, as Sanborn collects a variety of planimetric features such as road edges,
retaining walls, and hydrographic features in 3D.
The database structure for the project will be uploaded to each softcopy workstation. Quality assurance steps
will be in place during the data capture process to ensure that each required planimetric feature is collected to
correct graphical representation and attribute requirements outlined in the data dictionary.
At the completion of the stereoscopic compilation tasks, the compiled model is reviewed using softcopy stereo-
display to ensure that all data was compiled correctly. A senior photogrammetrist performs this review, with the
specific responsibility of maintaining quality control of the project. The compiled file is superimposed over the
source imagery, and the required planimetric features in areas of change are reviewed. If features are
determined to be missing, or not properly merged into unchanged portions of the database, the location is
marked in the file in a separate layer and a QC note is inserted with specific comments. The model will be
recalled by the stereo compiler and any necessary corrections addressed. This procedure provides two-way
communication, ensuring consistency of data collection in terms of content and interpretation. Once the data is
complete and correct, the interactive graphic editing phase begins.

Page 32 of 39
Board of Supervisors: Sylvia Arenas, Betty Duong, Otto Lee, Susan Ellenberg and Margaret Abe-Koga County Executive: James R. Williams
Interactive Graphic Editing and Topological Structuring of Data
Graphic editing procedures involve a combination of interactive and
programmatic checks to ensure that the data is cartographically correct
and aesthetically pleasing, connectivity of linework is complete, and topology
requirements have been met. A variety of intermediate topology checks
are performed prior to the building of polygons from line data to ensure
that all features defined as being topologically structured have no
snapping errors (overshoots/undershoots/slivers). Polygon geometry is
created, attributes of all features are populated, and edge-match
checking between production blocks is performed.
Edge Matching
Checking for production block edge mismatches is a standard part of all Sanborn projects for clients that tile
their data. Using an automated process, each production block is checked against its neighboring production
block to ensure that all linework matches exactly. This ensures that attributes of the linework and/or polygon
data are also checked. At the conclusion of the process, the graphic technician digitally reviews each
production block and corrects any mismatches in line placement or attribution that were flagged by the edge
match process. This process is repeated until no errors are returned. Sanborn will ensure that planimetric
features will meet all topology requirements when the data is migrated into the target environment and make
the transition to the GIS as efficient as possible.
Layers, Colors, Symbols, Linestyles, and Annotation
Sanborn will format all data layers as detailed in the data dictionary. All symbols, colors, linestyles, and
annotation will follow the County’s desired conventions. Sanborn’s listing of data standards and criteria is
summarized in the following table.
Point Duplication a data string. Points will not be duplicated across production block boundaries unless it
Line Quality shall be achieved. Transitions from straight line to arcs shall be smooth.
Topology overlaps between features and/or feature classes will be avoided.

Page 33 of 39
Board of Supervisors: Sylvia Arenas, Betty Duong, Otto Lee, Susan Ellenberg and Margaret Abe-Koga County Executive: James R. Williams
Translation into Esri Geodatabase Format
Once the planimetric and DEM data are completely structured and edited, they are ready to be translated from
MicroStation .dgn to Esri Geodatabase format for delivery. Sanborn has a suite of proprietary translator
software that enables the translation to various target systems, including the Esri environment.
As a final check on the deliverable data, and with the County’s database design as the foundation, Sanborn
uses custom software modules to perform QA/QC checks:
• Features and associated attributes are validated for data integrity
• Edge matching processes are run between production blocks
• Data will be verified with the source data and documents for content (missing data) errors,
annotation integrity, and aesthetics
• QA/QC reports are generated and checked for errors; they may include:
o Ensure that all datasets have valid feature attribute tables (FATs)
o Ensure that all datasets have valid projection and coordinate system definition and properties
o Verify AOI coverage has been met
o Verify data edge matching across production blocks
o Validate topology
Sanborn’s fee assumes the above features will be collected from a single year’s existing orthoimagery or lidar
collection and delivered in a single ESRI Geodatabase with separate feature class for each of the above listed
features.
Sanborn will work with the County and/or partner agencies on final SOW, price and database design.
7.4. Change Detection
Sanborn has extensive experience in providing building/structure changes generated from 2D and 3D change
detection software and can deliver these data, as well as provide literature for the change detection software
solution. As the County prefers 3D change detection, Sanborn can provide this option.
To eliminate the time and expense of visually searching large datasets for changed features, Sanborn has
developed advanced analysis and processing techniques for application to imagery and lidar datasets. This
flow chart documents our comprehensive approaches to change map creation, polygon integration (e.g.
Parcel) and visualization/workflow.
Sanborn’s value-added Change Detection Viewer (CDV) is a web-based, easy-access viewer that is integrated
with Sanborn Oblique Analyst®. CDV includes the ability to view multiple windows of source data side by side.
Furthermore, the software allows the user to organize parcels based upon percent of change, or parcel
numbers, and addresses or other identifiers may be used to search for a parcel. Once a parcel is identified,
users can select it by clicking in the hyperlink and the resulting side windows will open showing the same
parcel with the two source images side by side. The Sanborn Oblique Analyst® software is integrated with the
CDV and enables immediate verification of areas showing percentage of change using multi-view, high-
resolution oblique imagery, minimizing unnecessary field visits.

Board of Supervisors: Sylvia Arenas, Betty Duong, Otto Lee, Susan Ellenberg and Margaret Abe-Koga County Executive: James R. Williams
Sanborn captures the building footprint to compare to a previous vector layer which greatly improves the accuracy and
percent change calculation. This data is then incorporated into the change viewer.
The change detection would be performed by updating either the 2020 or 2023 existing building dataset using the
current orthoimagery. Sanborn assumed the change detection would be performed on the county 3-inch orthoimagery
AOI (964 square miles).
Deliverable:
• Delivery of updated building outlines in Esri shapefile or Geodatabase format with percent change calculation and
change type attribute (new, updated, demolished, and existing).
If the County would like to use the Sanborn Change Analyst™ viewer hosted by Sanborn, this could be negotiated.
7.5. Ad-hoc LiDAR Collection
Sanborn offers the County the ability to request additional QL-1 LiDAR Collection ad-hoc to support
potential business needs. The collected data will conform to the same specifications as set forth in the RFP
or can be modified as needed. Other resolutions are available as well. Pricing will be based on the area
size, resolution, and product type.
7.6. Sanborn’s Complimentary, Post-Disaster Rapid Response LiDAR Collection Program
Sanborn will collect and deliver QL-1 LiDAR data to the County with the mobilization fee waived for
affected areas. Additionally, for Areas of Interest (AOI’s) 25 sq. mi or less, Sanborn will produce
classification at no charge. For AOI’s over 25 sq. mi. Sanborn will reduce classification costs by 75% (the
County would only be responsible for acquisition, calibration and 25% of the classification cost). Events
qualifying natural disaster are outlined below:
• Earthquake: Affected Areas of the County impacted by an Earthquake of 6.0 or greater, according
to the Richter Magnitude Scale (ML).
• Flood: Coverage is provided when a federal disaster declaration is
made.
• Terrorist/Man-Made: Affected Areas of the County damaging over 200 sq. miles of area resulting
from a terrorist attack or other man-made disaster.
• Hurricane: Affected Areas of the County impacted by Saffir-Simpson Scale Rating of Category
three (3) or higher

7.7. Sanborn’s Avalanche Sensor - Photon Counting LiDAR (PC LiDAR) Technology 20 ppsm QL-1
Offering
A next-generation lidar technology that detects individual photons rather than traditional beam returns—
designed to meet the rigorous accuracy, density, and formatting standards established by the U.S.
Geological Survey (USGS) for national elevation mapping programs. While traditional linear lidar offers a
cost-effective solution at lower point densities, Photon Counting LiDAR is ideal for achieving higher-density
data across large areas, making it especially effective for projects requiring high-resolution, USGS-
standard-compliant elevation data.
PC LiDAR collects in a cone shape pattern providing a straight down perspective as well as an oblique
perspective. This oblique perspective enhances the ability to penetrate foliage much more effectively and
prevents data occlusion.
With photon counting lidar, the array is mounted on a scanner that rotates at an angle to create a cone-
shaped field of view. As the scanner rotates, the photo diode array flashes up to 50,000 times every
second (50 kHz) and with the up to 4,096 measurements per flash, the system can collect 204.8 million
elevation measurements per second. The rotating scanner provides “look diversity” enabling the sensor to
capture 360 degree views around objects reducing the number of voids in the data.
Each square meter of terrain is sampled over a thousands of times in a single over-flight. The resulting
point densities are up to 100 points/m2 on ground surfaces and can be well over 200 points/m2 in forested
areas.
In addition to detail (high point density), a significant advantage is that photon counting technology
supports data collections at 11,000–18,000 feet (or higher) above ground level and operates with a large,
cone-shaped swath so that more area is covered during each flight pass, which can reduce the overall
cost of collection.
Photon counting lidar systems achieve detailed 3D representations of objects and can meet the QL level
accuracies similar to the linear mode, which supports applications demanding detailed models of current
conditions and change detection, such as in utility powerline, facility, forestry, and infrastructure
management. Photon counting is the ideal solution for clients who need to capture large areas while
retaining the ability to collect data at extremely high resolution.
USGS Exceptions:
• Multiple Discrete Returns
o Sanborn’s Avalanche system does not support multiple discrete returns. The number of
returns is set to one. The system collects numerous single pulses at multiple angles to
produce high-quality results.
• Intensity Values
o Intensity values represent estimated relative reflectivity rather than direct measurements
of pulse return magnitude. These values may be derived from multiple sources and are
produced as 16-bit output.
• Nominal Pulse Spacing (ANPS)
o For PC LiDAR data, the Aggregate model generates ANPS solutions from multiple
observation angles.

• Data Void
o Data void calculations are based on the aggregate model using single or only returns.
• Spatial Distribution and Regularity
o Spatial distribution and regularity cannot be assessed using first return points from a
single file Source ID in aggregate point cloud data.
7.8. California Public Records Act (CPRA) Request Support
In the event that the County receives a request under the CPRA for data provided by Sanborn under this Agreement,
Sanborn will provide technical support to manage and organize the data and allocate computers and staff to copy the
data to the Sanborn- or Requestor-provided external hard drive(s), ensure data copy validation and assurance, and
provide the drives to the CPRA requestor. A CPRA request may encompass the full Countywide dataset or a subset
dataset with a defined area of interest. The County will provide Sanborn with the request, and Sanborn shall have 10
days or a time period mutually agreed upon by Sanborn and County to deliver the data to the CPRA requestor. Price
will be calculated based on the Technical Hours specified in Exhibit B Fee Schedule.
o If Sanborn is purchasing the external USB drive(s) and shipping via Sanborn account: 3 Technical Support
hours.
o If Requestor is providing the external USB drive(s) and return shipping label: 2 Technical Support hours.
7.9. Technical Support for Data Management
Sanborn will provide technical support to manage and organize the data and allocate computers and staff to copy
the data to the County’s Microsoft Databox, external drive(s) or FTP, provide data copy validation and assurance,
and deliver the drives to the County-provided point of contact and address. A request may encompass the full
County-Wide dataset or a subset dataset with a defined area of interest. The County will provide Sanborn with the
request, AOI, and required deliverables. Delivery schedule will be negotiated based on requirements and mutually
agreed upon by Sanborn and County.
7.10. Independent Checkpoint Collection for Vertical Accuracy Assessment
To support compliance with the USGS Lidar Base Specification and ensure eligibility for 3DEP funding, Sanborn will
conduct an independent ground survey to collect vertical accuracy checkpoints. These checkpoints will be
surveyed using FGDC-compliant, survey-grade GNSS equipment and will be spatially distributed across the
project area. The collection will include both Non-vegetated Vertical Accuracy (NVA) checkpoints in open
terrain/bare-earth and Vegetated Vertical Accuracy (VVA) checkpoints in vegetated areas. These independently
acquired checkpoints will not be used in the lidar calibration or adjustment process and are intended solely for
vertical accuracy assessment and QA/QC verification in accordance with ASPRS/USGS guidelines.
