Georeferencing a map for free

[PeterC]

I know of two ways to georeference a map for free:

1. On your computer using QGIS Open source software.
There is a lot of information about QGIS, including:

• in this forum
• my own working instructions for georeferencing
• the official tutorial on georeferencing
• this tutorial from QGIS tutorials on georeferencing

QGIS is very powerful and has many functions besides georeferencing but may be daunting for someone just wanting something simple.

2. Online using the free Map Warper Georeferencing application from Tim Waters
There is a brief Map Warper Guide, but it is a fairly simple process. I have not tried this fully yet.

Bear in mind that once a map has been georeferenced it still needs to be tiled before uploading to the web for use. I have MapTiler software that can do this.
