I have an image of a fiber optics network map:
I want to turn this map image (without any actual GIS data) into a vector map where each point is defined by lat, long.
To do this, I'm trying to import it in QGIS. I'm using the OpenLayers plugin to have Google maps as a basemap layer. I have an empty vector layer with projection set to EPSG:3857 where I want to draw the points.
I can't import the image and position it correctly over the Google Maps basemap.
As suggested, I tried this tutorial, placing 5 points (4 at the edges and 1 at the center).
I import the map guessing the coordinate system to be `Any idea what projection was used to create that map?
I tried both pasting coordinates in this format
48.767479, -97.551781 (found on Bing Maps searching the name of the cities) and in this format
48 46 02.92, -097 33 06.41 found using this converter.
In both cases, I end up with a super small, distorted map off the coast of Gabon.
I also tried picking coordinates from this webpage instead, which gives me projected coordinates in EPSG:3857, and feeding them to the Georeferencer plugin worked. However, my image is now very distorted when shown on top of the Google Maps (or Bing Maps) layer.
I guess the projection is not Mercator. Any idea on how I can work on this map without the distortion?
