Question

How is a coordinate system changed in a data frame to match the coordinate system of a desired layer contained within?

A. The desired layer must be reloaded to the map document (. mxd) in order to inherit the coordinate system
B. The coordinate system must be saved as a projection file (. prj) and imported to the data frame
C. The layer can be selected in the Coordinate System tab and selected as the data frame spatial reference
D. The data frame can be set to inherit the coordinate system using the Project tool

Answer 1

The coordinate system of a data frame can be changed to match the coordinate system of a desired layer by selecting the desired layer as the data frame spatial reference.

Step-by-step explanation:

The correct answer is C. The layer can be selected in the Coordinate System tab and selected as the data frame spatial reference.

When working with geographic data in a data frame, it is important to ensure that the coordinate systems are consistent. To match the coordinate system of a desired layer, you can select the layer in the Coordinate System tab in the properties of the data frame. By choosing the desired layer as the data frame spatial reference, the coordinate system of the data frame will be changed to match the layer.

For example, if you have a data frame with a coordinate system of WGS 1984 and you want it to match a layer that is projected in UTM zone 11N, you can select the UTM zone 11N layer as the data frame spatial reference. This will change the coordinate system of the data frame to UTM zone 11N.
