Re: [otb-users] Orthorectify the FORMOSAT-2 image

[Guillaume Pasero]

Hi, Yes OTB should be able to orthorectify an image with an RPC, even if the sensor is unknown. You could try creating a .geom file that goes with the image and contains the RPC coefficients (this file allows to define the geometric model parameters). You can check examples here : https://git.orfeo-toolbox.org/otb-data.git/blob/HEAD:/Input/IKONOS_BLOSSEVILLE_ROI_1000_100.geom You will probably have to change the "type" to ossimRpcModel, remove the support_data, and maybe choose a fake sensor name. There are extended filenames to specify a geom file to load with the image : "my_image.tif?&geom=path_to_geom" Regards, Guillaume On 04/07/2016 05:12 AM, Bor-Chwan Chen wrote: Dear OTB-er: We try to promote the OTB to be used as an VGI-tool in Taiwan. One of the key step is to orthorectify the FORMOSAT-2 image. I've checked the documents and found out OTB does not support FORMOSAT-2 orthorectification directly. However, the alternative RPC approach seemed to be the right way. Am I correct? If so, does the .rpb comes with the Level 1a product is all I need? Could someone help me?
