How do I get georeferenced data?

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

  1. Add the raster dataset that you want to align with your projected 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 many control points for Georeferencing?

With a minimum of three control points, the mathematical equation used with a first-order transformation can exactly map each raster point to the target location. Any more than three control points introduces errors (or residuals) that are distributed throughout all the control points.

How do I save Georeferencing in Arcgis?

Click the Georeferencing drop-down menu and click either Update Georeferencing or Rectify. Updating the georeferencing will save the transformation information with the raster and its auxiliary files. Rectifying will create a new file with the georeferencing information.

How do I add a Georeferencing toolbar?

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.
