2.1.2 Data Capture Method
Data capture shall be in direct, digital form using Microsoft UltraCAM Eagle model
digital sensor. Imagery shall be acquired at a nominal ground pixel resolution less
than 3" and used for developing 3" (three inch) pixel orthophotography and other
deliverables. The Contractor may resample from a smaller pixel resolution to
achieve the specified pixel resolution and shall avoid resampling from a larger pixel
resolution to achieve the specified pixel resolution.

2.1.3 Capture Conditions
Leaf -off conditions and no haze, clouds, fog, dust, smoke, air pollution, snow, or
other ground obscuring conditions shall be present. Capture shall occur within two
(2) hours before and two hours after maximum sun angle, and when the sun angle
is not less than 35 degrees above the horizon. Images shall not contain
objectionable shadows caused by relief or low solar altitude.
The downtown area of the City and other areas as shown on Map Figure 2 shall
be scheduled to occur as late as possible in the leaf -off acquisition window and at
high noon or at the time with the best solar angle possible to minimize shadow
effects of tall buildings. The true ortho area shall be acquired with 80% forward lap
and 80% sidelap.
Page 4 of 13
Figure 2 - True Orthophotography Flight Area
2.1.4 Flight Design
The average 4,733 foot flying height above mean terrain is designed to capture
aerial imagery at a pixel ground resolution slightly less than 0.25 feet square. This
flight height is appropriate for achieving the required final pixel resolution of 0.25
feet.
The flight mission shall be designed such that forward lap is 60% and sidelap 30%
in areas of gentle terrain. Crab shall not be in excess of three (3) degrees; and tilt
of the camera from verticality at the instant of exposure shall not exceed three (3)
degrees.
The flight mission schedule must include sufficient time for captured data to be
inspected and for any necessary reflights to be completed within the capture
window and prior to April 30, 2019 delivery schedule. Reflights shall be centered
on the plotted flight lines and must be taken with the same camera system. The
Contractor at no additional fee must correct aerial imagery that does not meet
defined specifications.
2.1.5 Horizontal Positional Accuracy
Horizontal accuracy testing should follow the ASPRS Positional Accuracy
Standards of Digital Geospatial Data, Edition 1, Version 1.0 — November 2014.
Accuracy tests will meet or exceed requirements for "Standard Mapping and GIS
work" which is a 2-pixel RMSEx and RMSEy accuracy class. For the 3-in imagery
this will be 6 inches.
Accuracy testing parameters shall be determined by the Contractor in consultation
and with concurrence of the City's Project Manager. Complete accuracy testing
results of all well-defined points shall be provided in the metadata to the City at the
time of data delivery. The City may choose to use a third party to validate the
Page 5 of 13
accuracy of the dataset.
2.1.6 Aerial Triangulation (AT)
Aerial triangulation will be performed using industry -standard procedures and
software packages to support the horizontal accuracy requirements of the
orthophotography as detailed in the proposal.
2.1.7 Image Quality
Orthophotography shall be clear and sharp in detail with no noticeable blemishes
and be radiometrically and geometrically corrected to enable adjacent files to be
displayed simultaneously without obvious differences in tone, contrast, or position
of ground features between single images, across the block, or across the
database.
The most nadir part of every image will be used in mosaicking. Seam lines will be
created to ensure that joins do not cut hard detail and will not cross through above
ground structures. Visible seams within a tile or between tiles, which exhibit a
noticeable "edge" or "displacement' effect, will be grounds for rejection of tiled or
mosaiced data.
The imagery shall not contain defects such as out -of -focus imagery, blurs, whorls,
color blemishes, or any other kind of digital blemish or data corruption.
Feature warp or misalignment, smearing, double image, or image stretching
indicating bad elevation data shall not be present and will be grounds for rejection
of tiled or mosaiced data.
Distortion resulting from elevated surfaces such as bridges and interchanges or
other abrupt changes in elevation shall be corrected or removed.
Occlusion and smearing in areas of extremely high relief shall be fixed or
minimized to the extent possible using overlapping orthophotos.
Color and contrast adjustments are allowed in post process production provided
that information is not lost in the shadows or highlights as a result of the process.
Image quality will be approved by the City at the pilot project phase.
2.1.8 Pilot Project
The contractor will conduct a pilot project before executing final deliverable
production. Pilot project deliverables will be provided to the City for assessment
and input on general project quality, color, aesthetics, and to test out final
deliverable formats. The pilot project area will be determined in consultation with
the City and may be discontinuous and shall represent urban, rural, downtown,
and semi -urban areas.
2.1.9 Image Tiling
See Section 2.2.1 of this Scope. Tile grids based on previous projects will be
supplied by the City. Orthophotography files will be named according to the locally
used tile identification.

2.1.13 Building Footprint Update
The City will provide the current building footprint coverage as derived from the
2018 aerial flight for updates. This coverage will be updated by the Contractor to
reflect the building footprint structures that have been added, modified, and deleted
as observed in the newly produced aerial orthophotography. This will be
accomplished with change detection techniques employed on the current footprint
coverage compared to the new aerial photography. The contractor will provide a
delivery of the updated building footprints in a single geodatabase . These updated
building footprints will have consistently populated attribute fields as provided in
the City schema. Updated building geometry will be limited to buildings exhibiting
120 square feet or greater change.
2.1.14 True Orthophotography
True orthophotography shall be developed in areas in the vicinity of downtown and
as indicated in Figure 2. Selected buildings greater than five (5) stories in this area
shall be modeled to allow for the correction of building lean and occlusions.
Planimetrically accurate and topologically sound feature data shall be collected to
provide for detailed digital surface modeling of extruded building walls and relevant
building roof superstructure detail. Additional aerial photography shall be collected
with 80% overlap to facilitate the correction of occlusions in identified true
orthophotography areas.
2.1.15 ArcGIS Image Service Cache
Image Service Cache generated from ESRI ArgGIS image service as compact
cache storage format. The cache schema will be defined by the City's existing
cache used in 2010, 2015, and 2016.
2.1.16 Metadata
Complete, Federal Geographic Data Committee (FGDC) compliant (reference
FGDC-STD-001-1998) metadata shall be provided for each component of the
project, including digital orthophotography, building footprint collection, and
DEM/DTM data. All metadata shall be delivered at the same time and on the same
media as the dataset delivery. Each delivered metadata file will include the City of
Lubbock disclosure statement.
2.1.17 Data Review
At the start of the Quality Review, Corrections, and Accuracy Assessment Task
period as shown on Figure 3, Project Schedule, the Contractor, in consultation with
the City, shall determine an efficient electronic method which allows the City to
review orthophotography data and Contractor -generated quality control error calls.
These methods may include physical data deliveries (e.g. pilot project data), web
services via a geospatial portal (browser based), and/or webservices delivered
directly to the City's desktop GIS environments (ECWP, WMS, Image Service)
2.2 Project Deliverables
2.2.1 Data
A single set of deliverables shall be required. The City of Lubbock will use the final
deliverables with ESRI software packages and all data requested must be useable
Page 8 of 13
in this suite of software with no further manipulation.
Product deliverables are defined in the Delivery Manifest Exhibit.
2.2.2 Media
Digital data deliverables shall be provided on industry standard removable hard
drives with high speed transfer rates including USB 2.0, USB 3.0 connections.
4.0 Product Acceptance Procedures
The Contractor is responsible to assure that all services and products required by this Scope are
performed and provided in a manner that meets all professional and engineering quality standards
and industry -accepted photogrammetric principles.
The Contractor shall warranty all project deliverables for a period of two (2) years from the final
product delivery date in the project schedule as negotiated in this Agreement. The warranty shall
include compliance of all deliverables to the technical specifications, product accuracy
specifications, and data format and software compatibility as outlined in this Scope, or as stated
and affirmed by the Contractor. The Contractor is responsible for replacing deliverables found to
be deficient or defective and costs associated with accomplishing the replacement of data under
warranty shall be borne by the Contractor with no additional cost to the City.
The City's Project Manager shall be the point of contact with the Contractor for notification of
deficiencies or defects. The warranty shall stipulate that the Contractor shall complete the repair
or replacement of the defective product within ten (10) working days from receipt of a written
notice from the Project Manager, or the Contractor shall meet with the Project Manager within five
(5) days of receipt of the written notice of defective product or product not in compliance with
specifications. If after meeting with the Project Manager, the data is found to be deficient or
defective, the repair and replacement shall be completed within ten (10) working days as
stipulated herein, or within a reasonable time period agreed upon by the City and the Contractor.
