| Abstract | This task order consists of natural color digital orthophoto production covering an area containing the Minneapolis - St. Paul downtown metropolitan area in Minnesota. [Note: this metadata record was reformatted at the Minnesota Land Management Information Center from the record provided by USGS - several of the fields including the Bounding Coordinates, Transfer Format Name, and Lineage fields were changed to reflect LMIC's seamless data delivery] |

| Attribute Accuracy | ||||
| Logical Consistency | GeoTIFFs conform to the specifications set forth by the USGS for the similar production of 133 Urban Areas orthophotos. | |||
| Completeness | Orthoimages are visually inspected for completeness to ensure that no gaps or image misplacements exist within and between adjacent images. These images are derived by mosaicking multiple images to ensure complete coverage. Source imagery is cloud free. | |||
| Horizontal Positional Accuracy | The ortho-rectified image frames and mosaics have a horizontal positional accuracy not exceeding 3 meters RMSE XY (2.12 meter RMSE x or y) for 95% of measured points according to NSSDA guidelines. The Band Co-Registration offsets are less than 1 pixel. No double-images or ghosts from interleaving of overlapped image frames are present. Approximately twenty (20) photo identifiable control points were measured in the orthos and compared to the surveyed locations to ensure the horizontal accuracy. |
|||
| Vertical Positional Accuracy | N/A | |||
| Lineage | USGS Processing Steps, April 2008 All photography was acquired using film cameras and accompanied by the collection of airborne Global Positioning System (GPS) data. All imagery was collected using Inertial Measurement Units (IMU) as a means to control the imagery. Orthorectification was performed with Intergraph's ImageStation OrthoPro software and the USGS National Elevation Dataset was used for the elevation model. Digital orthophotos were also radiometrically balanced in Intergraph's OrthoPro software. LMIC's Processing Steps, August 2008 USGS delivered the imagery to LMIC in TIF format in 195 tiles with no overlap. LMIC staff read them directly into a database and serves the images over the web via a WMS server in JPG format. |
