Oakland County
remote-sensing image
EnterpriseOrthoTC2008ImageService
Oakland County is included in the Southeast Michigan Regional Orthoimagery project encompassing approximately 3613 square miles of the Detroit metropolitan area and surrounding counties. Aerial imagery was collected using an Vexcel Ultracam digital sensor. The orthoimages are composed of 4-bands (RGB and near-infrared) and are tiled to a 1500 meter x 1500 meter grid. The orthoimagery is true color with a resolution of 0.3-meter per pixel. Orthoimagery tiles were delivered in Tiff format. A total of 1170 tiles that overlap Oakland County were adjusted by USGS to mimic State Plane (2113) International Feet using a custom Python Script. The adjustment was done tile-by-tile, so some 'no data' areas exist at the edges of the tiles. All imagery was taken in the spring of 2008.

The datum was mis-specified in the metadata and in the GeoTIF tags. The vendor has confirmed that the imagery was collected, processed, and delivered in UTM, NAD83-HARN, but the metadata and GeoTIF headers show it as NAD83(86). The effects of this problem vary depending on both your location (the shifts are not consistent across the region) and the software used. Through most of the region, the shift is between 1 and 3 feet East-West, and less than a foot North-South. Depending on the shift, the software used, and the data available for comparison this offset may or may not be discernible. The USGS developed a set of shifted tiles that position the actual data back in NAD83(86).

The digital imagery for each acquisition sortie is differentially rectified to produce orthophotography for the Red, Green, and Blue and near infrared channels at a resolution of 0.3-meter per pixel. Once the imagery has passed quality control review, final radiometric adjustments are performed to create a uniform overall appearance.
Compliance with the accuracy standard was ensured by the collection of airborne GPS data and surveyed ground control.
Accuracy assessment determined by evaluating the horizontal accuracy of the ortho imagery as compared to the airborne GPS/IMU data and NGS monuments.
National Map Accuracy Standard (NMAS). Not to exceed 3 meters RMSE horizontal.

For the orthophoto product, there is no vertical accuracy.
Orthoimages were created by Sanborn Map Company, Inc. using the proprietary Metro processes. Images were rectified using the DEM and or LIDAR data along with the aerial triangulation solution. Images are mosaicked and colorbalanced using image processing tools developed by Sanborn. The images are then checked for compliance against the contract accuracy standards and corrected where non-compliant. The orthoimagery is cut to their final image file format and naming scheme provided by the USGS. For the county-wide orthoimagery, DEM supplied by USGS was used as the DEM source.
