- The plot window, by clicking Map in the Object Manager and in the Property Manager clicking the Coordinate System tab. Click the Change button.
- The plot window, by clicking the layer (i.e. Contours) in the Object Manager and in the Property Manager clicking the Coordinate System tab. Click the Set button.
Once in the Assign Coordinate System dialog, you can find your projection or coordinate system. Here are some tips:
- Enter the EPSG number or a part of the coordinate system name in the search bar and click the Search button.
- If your data is in latitude and longitude, open the Geographic (lat/lon) section and select the datum of your lat/long data. Usually, this is World Geodetic System 1984.
- If your data is in a predefined system (ie. some regional projection or coordinate system, UTM or State Plane), open the Projected Systems section and drill down from there.
- If your data is in a projection (ie. Lambert Conformal Conic) that requires user input (ie. Central Meridian), click the New button. Give the new projection a name, specify the base projection, the projection parameters, select a datum (or make a custom datum) and click OK.
If you will use a particular projection over and over again, click the Add to Favorites button. This makes that particular projection easy to find and access by including it under the Favorites section.
If you need to use a coordinate system that is not listed, or you cannot find, please email firstname.lastname@example.org.
