digital raster data
This delivery contains a 4 foot resolution bare-earth DEM in geodatabase format. The following are the collection parameters and equipment used to create these data sets: Aircraft: Cessna 320 (43Q) lidar System: Optech ALTM Gemini (03SEN145) Approximate Collection Altitude (Above Mean Terrain): 1400 meters Ground Speed: 150 kts lidar Pulse Rate Frequency: 70 kHz Mirror Scan Frequency: 48 Hz Scan Angle (+/-): 12 degrees Accuracy statements are based on areas of moderate terrain, with points classified as ground. Diminished accuracies are to be expected in areas of extreme terrain and dense vegetation. The accuracy of each point is expected to meet the vertical accuracy standard, derived products may be less accurate in areas of extreme terrain and dense vegetation due to a lesser number of points defining the ground in these areas. Classified data sets such as this one may have varying posting due to some pulses not reaching the ground.
The purpose of this data set is to provide a source for current and accurate digital elevation models (DEM) with vertical accuracy of 0.50 foot or better and with a nominal point spacing of 0.81 meters. This data is not recommended for design grade mapping or engineering without a ground truth survey.

All these data products were acquired at 1400 meters above mean terrain (AMT) and have a horizontal accuracy of 0.40 meters, with a nominal point spacing of 0.81 meters as per manufacturer's specifications, not field verified.
This value was computed by verifying the lidar data against ground surveyed points provided by DOWL/HKM. We recommend a ground truth survey of the data set. Without the ground truth survey check this data is not recommended for design grade mapping or engineering.
This value was computed by verifying the lidar data against ground surveyed points in open terrain. Vegetated and/or sloped terrain may yield diminished accuracies.
