The project file is added to the Source list.īy clicking the Save As button, you can save the changes made to the raster type so it can be reused at another time. This is an optional parameter and must be specified if the camera information is not in the project file.
Click the Camera browse button, navigate to the camera file, then click Open.To add vertical exaggeration for visual effect.Horizontal coordinate units of the dataset, which may be feet, The z-factor is a scaling factor used to convert the elevation values for two purposes: This could be used to offset elevation values that do not start at sea level. The base value to be added to the elevation value in the DEM. Optionally, you may need to set the Elevation adjustment parameters.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. When using the Match-AT raster type, the average elevation is read from the DEM provided.Įnter the value of the constant (average) elevation for the area covered by the images.Ĭhoose the DEM from a raster dataset, mosaic dataset, image service, or WCS service that you want to use for orthorectification. The available options are described in the following table: Click the Orthorectification using elevation radio button to choose an appropriate elevation option.Make sure the spatial reference system in the exterior orientation file and the DEM are the same otherwise, you may have to modify the DEM by either checking the Geoid check box or entering a z-offset and factor values.
