Project Description:

Chevron Mining, Inc. contracted Cooper Aerial Surveys Co. to provide photogrammetry and surveying services for a 33 square mile area. These services served as an update to Chevron’s existing imagery base. Working closely with URS, Cooper Aerial Surveys Co. provided surveying services, Airborne GPS set-up and post-processed data in
the mine coordinate system.

Due to the diverse terrain in and around Questa, NM and Questa Mine, Cooper Aerial Surveys Co. customized the color stereo photography flight to insure the efficient forward gain and side lap of the stereo photography to ensure a seamless product.

The project limits include the entire Questa Mine, US Highway 38 as well as Questa, NM city limits, over 21,000 acres.

The topographic data, 2’ contours and planimetrics, delineate the rugged mountains,  steep valleys, numerous mining features along with residential and commercial developments.

The color ortho-rectified photography and small portions of mapping were delivered as the initial product with 20 square miles of mapping to follow as the client requested.

• Ortho-rectified photography
• .24’ ground pixel resolution
• 30 square miles

Project Description:

Erie and Associates contracted Cooper Aerial Surveys Co. to provide photogrammetry and surveying services for a 30 square mile area. These services were tailored for planning purposes and flood plain analysis. Six Height Modernization control points were established creating a geodetic network with the help of the NGS of 40 points encompassing the Town of Eloy, Casa Grande and Florence. Airborne GPS (ABGPS) was utilized to maximize the cost efficiency on this project.

The project was located in Casa Grande, AZ and the property is expected to be developed in the near future. Once developed this property will be one of the largest residential developments in Casa Grande.

Project Classification: Citywide Mapping

Project Scope:

• 1:7200 Stereo photography
• 2’ contours generated
• Ortho-rectified photography
• .24’ ground pixel resolution
• Airborne GPS
• 50 square miles

Project Description:

City of Sedona contracted Cooper Aerial Surveys Co. to provide photogrammetry and surveying services for a 50 square mile area.  These services were tailored for planning  purposes and enhancing the City’s GIS database. Alongside Shephard-Westnizer, Cooper   Aerial Surveys Co. provided surveying services including, aerial panels, Airborne GPS set-up and post-processed, updated all City control points to NAD 83/88.

The project limits include portions of Oak Creek canyon, downtown Sedona, Sedona Airport, and the  developed areas of the Red Rock country within the City limits. 2’ contours delineate the countryside side and planimetrics  serve as a backbone to the City’s GIS database.

GIS database was updated with the vector data extracted from the 2007 Photogrammetry data. FGDC formatted metadata was provided to insure data integrity and quality   control. Ortho-rectified imagery also provided in a user friendly tile definition format

Calexico, CA Border                    

Project Classification: LIDAR

Project Scope:

•  1:7200 Black/White Stereo photography
• LIDAR
• 2’ contours generated
• Color Ortho-rectified photography
• .25’ ground pixel resolution
• 579 acres

Project Description:

AMEC contracted Cooper Aerial Surveys Co. to provide photogrammetry services for a 579 acre area or 9 linear miles.  Cooper Aerial worked closely with Paul Sowers RLS of AMEC surveying department to insure the proficient placement for the 33 aerial targets.  Due to restricted areas, survey crew were not able to set and control 7 of the 33 aerial targets.  To accurately provide photogrammetric mapping for the areas that did not contain aerial control we utilized LIDAR.  We contracted an aerial provider that utilized both a digital camera and LIDAR system.

Using both the traditional photogrammetry and LIDAR data, we provided AMEC with 1”=100’ map with 2’ contours.  AMEC used the photogrammetric mapping for engineering purposes.  AMEC was very pleased with our services and the project was completed in 1 month.

Phoenix, Arizona

Project Classification: Flood Control

Project Scope:

• 1:4800 Stereo photography
• 2’ contours generated
• Ortho-rectified photography
• .15’ ground pixel resolution

Project Description:

For this particular project Cooper Aerial Surveys Co. provided, through the use of ABGPS, 1:4800 1”=50’ scale mapping with 2’ contours.  The project boundary was from the 24^th Street Bridge to Alma School Road and 200’ beyond the banks of the Salt River channel.  The mapping was furnished for floodplain planning purposes and was referenced to the County’s GIS/HIS database.

Cooper Aerial Surveys Co. also provided all ground surveying services to the client.  We set and controlled 48 aerial control panels and provided all ABGPS surveying services.  Also, we provided cross sections surveys along the banks of the Salt River at 500’ intervals.  The cross section surveys extended for the entire length of the project, which was approximately 10 miles.  Finally, all hydraulic structures within the river bottom were surveyed and a detailed map of these structures was supplied to the client.

The Flood Control District of Maricopa was extremely pleased with our customer service and delivery schedule.  We have performed numerous mapping and surveying projects for the DISTRICT over the years, while continuing our on-call contract.

Riegelsville, NJ

Project Classification: Bridge and State Infrastructure

Project Scope:

• 1:500 Stereo photography
• Flown by Bell 206 Helicopter
• 0.2’ Contours Generated
• Ortho-rectified photography
• 2 inch ground pixel resolution

Project Description:

Pinto Engineering contracted Cooper Aerial Surveys to provide low level aerial photography and mapping services with the use of a Bell 206 helicopter less than 250 feet above the bridge deck for super high quality imagery for the mapping process.  The main purpose of the project was to map the tops of the suspension cables with a very high degree of accuracy.

The contours were successfully compiled at an interval of 0.2’, and the horizontal and vertical point accuracy specifications are above and beyond project requirements.  Cooper Aerial Surveys was able to successfully read vertical positions with an accuracy of roughly .05’.

For this project, 1:500 scale black and white stereo photography with a pixel resolution of approximately .02’ was flown and furnished to Pinto Engineering.  The imagery was then used to generate 1” = 5’ scale mapping with a 2/10^th’s’ contour interval.  The mapping was done as a DTM and delivered in AutoCAD and Microstation format on CD-Rom.  Cooper Aerial also provided an ortho-rectified image of the entire site.

“Bridge mapping utilizing modern geospatial aerial mapping services is a new concept” stated Jeff Cooper, owner of Cooper Aerial Survey. Mapping the bridge presented many technical challenges that had to be overcome. Mapping the suspension cables along with other nuts and bolts to accuracy more than 15 times a conventional design project was managed by Philadelphia project manager, Philip Gershkovich.
