+## Creating zones for habitat images
+1. Create png image from original svg with approprate crop.
+2. Create zone polygons/rectangles on the original svg with divider lines anchor points as a guide 
+3. Copy zone polygons/rectangles to png image and size to fit (this is to ensure the only paths on the image the selectable ones)
+4. Ensure all overlays have an almost transparent fill (lowest transparency value - in Inkscape this is 1) and no outline
+5. Add a 'label' (not an id) to each overlay to match with a column name relating to the zone segment, this may be repeated. In Inkscape this is under 'Object Properties'.
+6. Save the png with overlays as an svg (it may either be inkscape or plain svg)
+7. Place svg in relevant directory (`./frontend/src/assets/img/habitatSVG/`) in the frontend
+8. Find and replace any instance of colons (:) in property names for the raw svg i.e. inkscape:label -> inkscapelabel. A helper script has been written to do this automatically please run `python process_svg.py`.
