Ortho button not active

I wanted to Ortho rectify GeoEye HR imagery using existing RPC and IFSAR DTM in Image Analysis. According to ArcGIS Resource center http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/using_the_Orthorectify_button/009t000000mv000000/ the button is automatically active if the imagery has RPC file. In my case the ortho button was not active although my Imagery has RPC file. Please advice thank you.

    All of your image analysis options are grayed out. Did you make sure to click and highlight the layer in the list in your Image Analysis window?

  • Thanks. I missed out that step. I already click and highlight on the layer but still the Orthorectify button does not active. Any other step i missed?

    Sorry - this is one that I will need to leave to the imagery specialists. I'll add a tag for raster to help get it in their lists.

  • Thank you very much. Still cannot find the way to do Orthorectification for GeoEye1 in ArcGIS.

You have to select both layers, the image and the DEM used for orthorectification. And the image has to have a RPC or RPB file with the same name.
