Orthorectifying a raster dataset displayed in ArcMap

You can permanently orthorectify your image using the Create Ortho-corrected Raster Dataset tool or by exporting your orthorectified on-the-fly raster dataset layer using the ArcMap Export Raster dialog box, found by right-clicking the raster in the table of contents.

Steps:

1. In ArcMap, click the Add Data button to add the raster dataset that has rational polynomial coefficients (RPCs).
2. Right-click the raster dataset in the table of contents and click Properties.
3. Click the Display tab.

   If the raster dataset has RPCs, the Orthorectification using elevation options is active.

4. Check the Orthorectification using elevation check box.
5. Click Constant elevation and type the constant (average) elevation value to use.

   Alternatively, click DEM and click the browse button to choose the DEM.

6. Optionally, make an elevation adjustment by entering a z-factor, z-offset, or choosing whether to use a geoid model.
7. Click OK.
