vector digital data
This metadata record describes the planimetrics produced for The Metropolitan District by the Sanborn Map Company. This planimetry was stereo-compiled from 4-band (R, G, B, NIR), 8-bit per pixel aerial photography. The imagery was flown on April 16th and May 3rd of 2015 using an UltraCam Eagle camera and the planimetrics comply with the American Society for Photogrammetry and Remote Sensing Accuracy Standards (ASPRS) for Class 2, large scale maps at 1" = 40'. The average flight altitude was 4200 feet. This planimetry is published in NAD_1983_StatePlane_Connecticut_FIPS_0600_Feet (US Survey Feet). The Vertical datum is National American Vertical Datum of 1983 (NAVD88).
Planimetry for The Metropolitan District to serve as a basemap for GIS applications.

Data completeness was verified through visual inspection against the aerial imagery utilized for stereo-collection.
This planimetry meets ASPRS Class 2 Accuracy Standards for 1"=40' scale mapping
Specification requires that data meet a 0.8' RMSE requirement. Points were surveyed and compared to location within the planimetry and found to meet this specification.
0.455724-foot RMSE
N/A
Planimetric mapping accuracy is not assessed vertically, but rather horizontally.
0.0
QA/QC. Planimetric data was reviewed and reworked as necessary for quality, consistency and completeness.

Image Acquisition by Sanborn Map Company, April 16th and May 3rd of 2015 , Using a UltraCam Eagle Camera. Imagery and GPS/IMU data is downloaded from disc on the plane to disc on the ground. GPS/IMU mission data is processed together with simultaneously collected ground-based GPS base station data in forward and reverse directions. This precisely determines the aerial camera's position and orientation in the terrain (project) coordinate system and allows for correct orientation of the imagery.

Geodetic ground control is used to create a digital control file and control report as well as QC check of planimetric accuracy. Predefined points within the project area are targeted and photo-identifiable locations are measured. These points along with their precise coordinates are used in the AT process and to check the accuracy of the resulting planimetry.
