Review of Scope and Specifications

Surdex Corporation has been contracted to acquire, process and deliver leaf-off true color 6-inch and 12-inch ground sample distance (gsd) orthophotos.

  • Camera Type: Leica ADS100 Pushbroom Sensor
  • Acquisition Widow: Late December (after first hard freeze) – Late February (when deciduous trees are bare)
  • Sun Angle: 30 degrees or greater above the horizon
  • Airspace: Surdex’s Responsibility
  • Conditions: Free from haze, fog, dust, smoke, snow or floodwaters (streams must be with normal banks)
  • Clouds: Less than 5% cloud cover on any single photograph/image or tile
  • Sidelap: 20 – 30% over entire AOI – Min 15% - Max 45%
  • Building Lean: Reduced by adding supplemental flightlines
  • Flight Altitude: 1:1 ration between pixel and ground resolution

(6-inch at ~6,250’ agl & 12-inch at ~12,500’ agl)

  • Airborne GPS & IMU: Data shall be recorded at all times
  • Geodetic Control: Existing Control will be utilized and additional points will be surveyed as needed
  • Image Tile Scheme: Lambert Grid
  • Image Tile Buffer: No Buffer
  • Spectral Resolution: 4-band
  • Projection: State Plane – TX South Central and Central Zones
  • Horizontal Datum: NAD 1983 (2011)
  • Horizontal Units: US Foot
  • Metadata: Conformed to the Federal Geographic Data Committee (FGDC) Content Standard for Digital

Geospatial Metadata (FGDC-STD-001-1998)
