Is there a way to rasterize a GeoJSON file?
I have tried a lot of things, but all of them do not rasterize all the shapes found in the GeoJSON (more like 80% of the file is rasterized). How can I ensure all the geometry is rasterized and is of adequate size?
How to load shapefile into a binary raster?
Load Shapefile or GeoJson Define the shape_path with the path to the shapefile or the geojson file. The CRS of the image and the shapefile must be the same. If they aren`t, use QGIS to convert both files to the same CRS.
How to perform a reprojection in rasterio?
To perform the reprojection we will use the reproject function defined in the warp module of the rasterio. We will pass as arguments, the source as a rasterio band object (that’s the reason for the rasterio.band applied to the dataset), the desired CRS, and the destination resolution.
What’s the problem with rasterizing a shape in Python?
Your problem stems from the fact that when you rasterize a shape, using gdal_translate for example, you must determine the resolution of the raster, and it must be chosen in accordance to the “size” of your feature vectors if you want your raster to retain enough information.
What happens if there are no valid shapes in rasterio?
Return an image array with input geometries burned in. Warnings will be raised for any invalid or empty geometries, and an exception will be raised if there are no valid shapes to rasterize. shapes (iterable of ( geometry, value) pairs or iterable over) – geometries.
What are the features of the rasterio module?
Warnings will be raised for any invalid or empty geometries, and an exception will be raised if there are no valid shapes to rasterize. shapes (iterable of ( geometry, value) pairs or iterable over) – geometries. The geometry can either be an object that implements the geo interface or GeoJSON-like object.
How to polygonize raster to shapely polygons?
If the raster has been processed in a numpy array, the approach is listed below. Use rasterio of Sean Gillies. It can be easily combined with Fiona (read and write shapefiles) and shapely of the same author. Here is my implementation.
