convert MapInfo TAB (EPSG28992 RD) to geojson (ESP4326 wsg84)

import os
import geopandas as gpd

input_filename = 'input.TAB'
output_filename = 'output.geojson'

gdf = gpd.read_file(input_filename)
gdf = gdf.to_crs(epsg=28992) # first to RD ... needed to prevent weird offset
gdf = gdf.to_crs(epsg=4326) # wgs84
gdf.to_file(output_filename, driver='GeoJSON')

convert MapInfo TAB (force EPSG28992 RD) to ESP4326 wsg84 geojson

import os
import geopandas as gpd

input_filename = './Utrecht/Zuilen/MapInfo/Zuilen_Opstallen.TAB'
output_filename = 'Zuilen_Opstallen.geojson'

gdf = gpd.read_file(input_filename)
print(gdf.crs)          
print(gdf.head()) 
gdf = gdf.set_crs(epsg=28992, allow_override=True)
print(gdf.crs)
gdf = gdf.to_crs(epsg=4326)
gdf.to_file(output_filename, driver='GeoJSON')

GDAL

• install GDAL on Mac: https://formulae.brew.sh/formula/gdal

load .TAB file with geopandas

It seems that it also needs the MapInfo .ID, .IND, .DAT, .MAP files. Even for simple TAB files that don't have those.

geopandas

import geopandas as gpd

gdf = gpd.read_file('data/mapinfo2/Percelen.mif') # dit werkt
gdf.to_file('data/Percelen-MapInfo2.json', driver='GeoJSON') # dit werkt

gdf = gpd.read_file('data/mapinfo/Percelen.TAB') # dit werkt ook
gdf.to_file('data/Percelen-MapInfo1.json', driver='GeoJSON') # dit werkt ook
