# View
A map can be displayed using a variety of viewing options.
## Surface
Surface selects the source for the map’s 3D topography and coloring. There are 6 options:
**Elevation** shows the original surface before any dirt is moved. The map uses a Red to Blue gradient: Red indicates low areas and Blue indicates high areas.
**Design** shows the applied design—the surface you are trying to reach at the end of the dirt-moving process. It uses the same color scheme as Elevation.
Both the Elevation and Design surfaces determine the legend range.
**Cut/Fill** shows where the design will take dirt from and where it will put dirt. The layer’s coloring depends on the current Cut/Fill color scheme in Settings > Application.
The Cut/Fill legend shows a histogram.
**Satellite image** toggles the satellite image background on and off. The eye changes the visibility of the image to link to google earth.
## Layers
Turn defined layers on or off here, including the current surface (see above), depressions, drains, linework and loaded overlays such as KML. Use the buttons at the top to load and clear layers. Click the transparency toggle button beside a layer to change its transparency.
**NOTE:** The depressions layer is not shown if the project has only drains and no elevation surface.
