6.2.2 Layer Projection Tool

The Layer Projection Tool ensures compatibility between the coordinate system of your GIS layers (e.g., shapefiles, DEMs) and your VO project. It allows you to reproject any imported layer into a new CRS, ideally aligning it with the project’s coordinate system.

When to Use the Layer Projection Tool

Use this tool in the following situations:

  • When an imported GIS layer does not match the project’s coordinate system.
  • Whenever new GIS layers with differing coordinate systems are added.

How to Use the Layer Projection Tool

1. Access the tool:

  • Go to the Map tab.
  • Right-click on the desired GIS layer.
  • From the context menu, select ProjectTo.

2. Review the Layer Projection window:

  • The top of the window displays the current coordinate system of the VO project.
  • The middle section lists imported layers and their coordinate systems, helping you identify mismatches.

3. Select the layer to reproject:

  • Use the Import Layer dropdown menu to choose the layer you want to reproject.

4. Set the target coordinate system:

  • In the Target Coordinate Reference System dropdown, select the new CRS.
  • Ideally, choose the same CRS as the project to avoid compatibility issues.

5. Apply the reprojection:

  • Click Apply.
  • The layer will be converted and added to the Imported section of your project.

6. Check the reprojected layer:

  • The new layer will appear with a modified name.
