I'm a GIS Specialist with cartography and remote sensing background. I'm dealing with various spatial data everyday like shapefiles, kml, geopackage, gml, geojson, csv, etc. I can help you with your problem, what kind of data do you have and what do you want to extract/convert? I mostly using QGIS, GDAL, and ArcGIS to manage all my spatial data. Looking forward to work with you. Thanks!
