How do I get georeferenced data?

In general, there are four steps to georeference your data:

  2. Use the Georeference tab to create control points, to connect your raster to known positions in the map.
  3. Review the control points and the errors.

How do you capture control points?

Control points are captured by standing on top of them. The speed at which a control point is captured depends on how many players from the capturing team are present on the point: two BLU players capturing a RED point capture that point faster than only one BLU player would.
