The Esri equation is error = K1 + K2 * r 2 + K3 * r 4 They differ in how they use the coefficients, so the method used should match the way the coefficients were derived. There are two ways these coefficients can be applied: USGS Konrady and Esri Konrady. These coefficients model the radial distortion as a function of the radial distance from the center (r) as a power sequence. If it is not needed, leave the 0 value defaults.ĪrcGIS uses Konrady coefficients to calculate radial distortion correction for standard-frame cameras. Verify that this distortion value is needed. This may already have been applied by the camera's postprocessing software. If you choose Radial Distortions, you must click the Radial Lense Distortion Coefficient Method drop-down arrow and choose one of the options:.Once you've entered the values in this table, you can view the calculated coefficients by changing the Type of Distortion method to Konrady Coefficients. If you choose Radial Distortions, a table appears where you can enter the values provided in the camera calibration report.Click the Type of Distortion drop-down arrow, and choose either Konrady Coefficients or Radial Distortions.Enter the principal point of autocollimation along the y-axis in the PPA Y text box and choose the appropriate units.Enter the principal point of autocollimation along the x-axis in the PPA X text box and choose the appropriate units.Enter a value for Focal Length and choose the appropriate units.When using this raster type, you must edit the raster type properties by clicking the Raster Type Properties button. The main input file used by this raster type is the Applanix DSS eo_std.txt file. The Applanix DSS is a medium format, digital airborne remote sensing system, using integrated inertial technology to produce georeferenced color and color infrared (CIR) imagery. The Thermal template processes pixels into degrees Celsius. The All bands and Multispectral templates can process pixels into radiance or surface reflectance using the information from the imagery. Additionally, three processing templates are supported: All bands, Multispectral, and Thermal. When adding Altum data to a mosaic dataset, files will be filtered to search for the following extensions: *_1.tif, *_2.tif, *_3.tif, *_4.tif, *_5.tif, *_6.tif. tif files for the bands, one from each sensor, including five multispectral bands (blue, green, red, red edge, near-infrared) and one thermal band. The input files used by this raster type are the. MicaSense Altum produces multispectral, thermal, and high-resolution imagery from a multisensor system. When using this raster type, you can edit the raster type properties by clicking the Raster Type Properties button.įor more information about the ADS airborne sensor, see Leica airborne systems. The input file used by this raster type is the.

ADSĪrcGIS Pro supports the Leica ADS40 and the ADS100 Airborne Sensors. For specific steps, see Converting from orthometric to ellipsoidal heights. If you need to apply a geoid correction to your elevation data, create a mosaic dataset containing the elevation data, and use the Arithmetic function to apply the required equation. For all of these raster types, make sure the spatial reference information in the input files and the DEM are the same.
