## How to convert from SHP to GeoJSON (using ogr)

``` python
# Python >= 3.7
import ogr
import json

def shp2json(shp_path):
  """
  Convert SHP files to GeoJSON with OGR.
  Outputs JSON file to same directory as the SHP files.
  
  Input:
    - shp_path (str):
        e.g. "D:/somewhere/bangladesh.shp"
  """
  driver = ogr.GetDriverByName('ESRI Shapefile')
  data_source = driver.Open(shp_path, 0)

fc = {
      'type': 'FeatureCollection',
      'features': []
      }

lyr = data_source.GetLayer(0)
  for feature in lyr:    
      fc['features'].append(feature.ExportToJson(as_object=True))

output_name = shp_path.split(".")[0] + ".json"

with open(output_name, 'w') as f:
      json.dump(fc, f)
      print("GeoJSON file created: {}".format(output_name))
```
*You can also do it with libraries like geopandas.*
