                Description:

                                Abstract:

                                                As specified by the contract, ASPRS Large Map

                                                Class One standard natural color digital orthophotography

                                                at 1' pixel resolution will be created from 1:12000 photo

                                                scale color orthophotography and rectified to the bald

                                                earth DTM delivery - a deliverable of this contract.

                                                All data are geo-referenced to the New Mexico State Plane

                                                Coordinate Grid System, Central Zone, NAD83, NAVD88.

                                                The bald earth data is derived from an aerial LIDAR survey

                                                conducted at 1m postings over the month of April, 1999.

                                                The data sets are clipped into 5000' by 5000' manageability.

                                                Each tile is accompanied by a world coordinate file.  The

                                                format of the imagery is uncompressed, untiled, TIF.

                                               

                                Purpose:

                                                The data provided by this contract will be used by a variety

                                                drainage and roadway studies, site planning studies,

                                                property tax assessment, and other complex surface and

                                                sub-surface studies and investigations.

                                                The surface data will be used for engineering analysis and

                                                to digitally extract geometric data (cross sections, profiles,

                                                etc.) for use in hydraulic, geotechnical, and sedimentation

                                                computer models.
