| Jun 28, 2017 at 12:38 | comment | added | jrodriguezmonti | I would like to colorize the elevation. Some colors the higher, some other colors the lower, and so on. I want to know how to treat the data before representing it. I want to do that, and represent it as surface and heatmap. Thanks! | |

| Jun 28, 2017 at 1:14 | comment | added | jrodriguezmonti | Hi! Thanks for your reply. I like that way. Some questions about it. 1) Do you have any code examples to look at ? 2) Is it possible to plot the information already processed ? Because in some cases I do not have the original .img files. Thanks! | |

The easiest is probably to stick to the original raster format you had (.img), read the data directly as a numpy array (e.g. using rasterio), and plot the array with imshow or plot_surface
