To help you get started, we've selected a few fastkml. Using the code supplied, the KML file will only work in Google Earth. This is a simple Python string formatting exercise, which might be better researched in Stack Overflow. SVG-to-WKT converts SVG (Scalable Vector Graphics) into WKT (Well-Known Text), a markup language for representing vector geometry on maps implemented by spatially-enabled databases like PostGIS and MySQL. Commented Dec 18, 2021 at 18:04. features) KML files should only have one Document, Folder, Placemark in the root so this is likely just one element. ImportFromWkt(wgs84_wkt) # create a transform object to convert between coordinate systems transform = osr Given GeoJSON data as an object, return KML data as a string of XML. Next step is to write that data into a SQL DB, I am no expert in python, so I will put different logic: did you first try to convert shapefiles and see are they rendering in wanted region? or maybe create two scripts for specific goal you are trying to accomplish to see where is your mistake. The web site is a project at GitHub and served by Github Pages. wkt[18:-3] Fast KML processing in python. csv + WKT column) format (most commonly used in software such as PostreSQL/PostGIS, Spatialite or QGIS) or to many other formats I have a KML file provided by a user that looks like: <?xml version="1.
