Also, FGDC compliant metadata shall be provided in extensibe markup language (.xml) format for each dataset deliverable. NGA would like to see Reflective Surface Digital Elevation Model (DEM): 1-meter resolution grid from first and last return pulses. A Bare Earth DEM: 1-meter resolution grid and shall not include buildings, vegetation, bridges, or overpass structures in the bare earth model. Intensity Image: 1-meter resolution grid, intensity recorded from reflective surface (first return) pulse. Metadata files-one per each delivered data file.
FORMATS: ERDAS IMG; ERDAS Imagine formatted deliverables shall meet the following additional format requirements: All gridded data shall be coincident; all cells shall align in all delivered products; Image files shall be joined into the largest files supported by image formats; contiguous data shall be joined together (mosaicked) into a sinle ERDAS Imagine mosiac file; "No Data" areas shall be assigned a value of -999 to support any additional image mosaic operations in ERDAS Imagine; Projection information shall be encoded in ERDAS IMG file headers; Pyramid files shall be built on all IMG formatted deliverables; Elevation values within open waters shall be flattened to the best estimate of the surface water level in all DEM models; Metadata: FGDC compliant .xml file - Compliances shall be verified using the USGS
Metadata Validation Service available at http://geo-sndi.er.usgs.gov/validate.php.
PROJECTION: UTM (correct zone; horizontal and vertical units in meters). DATUM: Horizontal:
WGS84; Vertical: NAVD88, Mean Sea Level (MSL, [orthometric]. OUTPUT: DVD-R written at maximum of 2x write speed.
