a problem in 4.2Example using Mars MOC images

[squidward-qwq]

Hello, I have just started working with ASP, and my goal is to generate a DTM using ASP and stereo image pairs of Mars. However, I encountered some issues while generating the Mars DTM. First, I downloaded ASP and ISIS according to the UserGuide and successfully configured the environment.

Then, when conducting the experiment in section 4.2, I used ISIS to convert two test files, M0100115.imq and E0201461.imq, into .cub files and performed radiometric calibration. After that, I processed the stereo image pair using the command provided in the UserGuide. The generated DTM is shown in the image below. This image is not a grayscale image, and it hardly shows any topographic information.

Do you know what might be causing this issue? Is there a solution you could suggest? I would appreciate your guidance.

sorry this is the picture

It looks that you only created the PC file. This is a point cloud and will not show up well. You need to create a DEM out of it. This is described at https://stereopipeline.readthedocs.io/en/latest/next_steps.html#visualising. I also edited a bit the documentation in section 4.2 to make it more clear.

Thank you for your response; I successfully generated the DEM, which was of great help to my experiment. I will read the UserGuide carefully. Thank you very much.
