Which layer needs to be projected to the analysis coordinate system?Group of answer choicesLand CoverDEMOrtho PhotoBoth A and B

To determine which layers need to be projected to the analysis coordinate system, we need to consider the nature of each layer:

1. Land Cover: This layer typically represents different types of land cover (e.g., forest, water, urban areas) and is often provided in a specific coordinate system. If the analysis requires the same coordinate system, it needs to be projected accordingly.

2. DEM (Digital Elevation Model): The DEM represents terrain elevation and is also usually provided in a specific coordinate system. Like land cover, in order to conduct an analysis that involves measurements or spatial queries, it must be projected to the appropriate coordinate system.

3. Ortho Photo: Ortho photos are aerial photographs that have been geometrically corrected to be used as a map. They also need to be in the same coordinate system as the other data layers involved in the analysis.

Given that both the Land Cover and DEM layers require projection to coordinate systems for accurate analysis, the answer that encompasses both is:

Final Answer

Both A and B (Land Cover and DEM) need to be projected to the analysis coordinate system.
