Read geojson geopandas Reading and writing files#. In the following examples, we will use the geopandas. The (Geo)JSON standard is quite strict in the encodings that are supported: only UTF-8, UTF-16 and UTF-32 (JSON standard). This example is simply a point, so besides reading in the JSON, nothing necessarily has to be done, so we’ll just geopandas can read almost any vector-based spatial data format including ESRI shapefile, GeoJSON files and more using the command: geopandas. Assuming you have a file containing both data and Photo by KOBU Agency on Unsplash.
