CRISM TRR3 Map projection Algorithm
soul45 posted a topic in For data usersHello, I am currently working with the CRISM Data in Matlab and when I load it, the data is always saved in a rectangular matrix. But since I need the original shape, I need to transform the cube data into it's original form. I have two screenshots how it should look like. I have also been able to read out the DDR file, but I can't find anything on the web on how to use that data. I would appreciate it if someone could help me further regarding this.
Location and orientation of Galileo images
Guest posted a topic in For data usersHello, I'm using MATLAB to load and plot the Galileo SSI .img image files. I'm using the fread function to load the image-files and I then remove the surrounding excess data. My problem arrives when I try plotting the images on the surface. They don't seem to match up and appear to be shifted ~1deg west. In addition, the images seem to fit together better if I flip the images left/right, but I don't know why. In Nasa view, they have a totally different direction. Anybody who can help me? Thanks - Sandy
