As part of the strategy for implementing GeoBase throughout the Air Combat Command (ACC)
division of the United States Air Force, Western Air Maps, Inc. was contracted to collect
planimetric and topographic data in support of the development of a digital mapping database
and Geospatial Information System (GIS) along with geo-referenced Common Installation Picture
(CIP) for Whiteman Air Force Base and surrounding environs.
New color aerial photography with ABGPS & IMU was flown at 4,000' amt photo scale 1"=330'
using N739C our Piper twin-engine aircraft and Zeiss RMK-A aerial mapping camera equipped with
FMC.
Existing Primary Installation Control Station (PACS) and Secondary Installation Control Stations
(SACS) were recovered and targeted prior to the flight.
Precision scans of the aerial photography were produced using the Vexcel UltraScan 5000 yielding 6"
pixel resolution. AeroTriangulation adjustments were performed using ISAT and Pat-B by a
Certified Photogrammetrist.
Map compilation was conducted using digital softcopy workstations (SSK’s) for collection of DTM
surface models (ArcTIN) and planimetric features. Collection of 3-D buildings and production of
'true-ortho photo rectification took place using SocetSet workstations. Orthos were delivered in
TIFF and MrSID formats.
All map features collected under this contract adhered to NSSDA and NMAS, and were
delivered for use in ESRI ArcGIS format where each feature type (class) is a layer in accordance
with the Spatial Data Standards for Facilities, Infrastructure, Environment (SDSFIE).
Metadata was produced for mapping and orthos and submitted in ARCXML format.
