I have few SVG files (maps) that I want to convert to GEOJson. On those SVG files, two markers (crosses) had been drown in order to georeference the layer. So I know the coordinates of those control points, I am able to calculate the parameters : How to compute parameters for QGIS Affine transformation?.

My plan is :

  • Read the SVG file and extract the paths.
  • Store the coordinates of the shapes in an array
  • Apply the affine transformation
  • Write a GEOJson file

I have already extracted the paths with python (svgpathtool), but I have no clue on how to exploit that.

Is there a better way to do that ?

How to translate the path ?
