Suggestions on how to generate a mask
3 views (last 30 days)
I have a matrix that is 1440x2880 of remote sensed temperatures from satallites, i was wondering if there is any way that i can mask all the data points in the United States. To make this clearer, i would like to create a matrix full of 0's and cells in the United cells will be expressed by 1's for example. But i was wondering if there is a way to do this

If you have Mapping Toolbox, read the data file containing the borders of the states (see the "Enter MATLAB" section of this blog post) and ask if the points in your temperature data are inside the union of the polyshape array containing all the states. The isinterior function will help you do that last step.
