LAR-IAC 2 will include building rooflines:
- Every building over 400 square feet
- Will match LAR-IAC accuracy standards
- Simple Building Outline
- 2D Polygon with Elevation Attribute
They will be collected from stereo imagery collected January 2008 through April 2008 (L2 imagery acquisition). The planimetric features (building representations) shall be topologically correct and meet the American Society for Photogrammetry and Remote Sensing (ASPRS) accuracy standards for large scale class 1 maps for 1” = 100’ (and 1” = 200’ for some areas) mapping in order to be incorporated into existing participants’ GIS systems.
