I am quite new in coding and wanted to ask if there are some simple examples and source codes with the similar functionality as this website https://maps.canada.ca/czs/index-en.html which basically:
- a website to display rasters
- then enables users to select and crop certain area of the raster using either uploading a shapefile or draw bounding box
- download the cropped raster as certain raster format (.tiff for example)
