The surface import modal is the tool to import surfaces to the 2D map view of Glex. The surface is converted to a flat representation of the actual surface and includes hill-shading, contour lines and color gradient choices.
Currently, the following formats are supported:
.zmap
.xyz (only when gridded)
.tiff (geotiff) [coming soon]
There are currently some limitations to these files:
Files can be no larger than 100mb.
The CRS of the file has to use ED50 as its datum. (lat-long is not supported)
Using the surface settings it is possible to customize the surface.
Color selection: select the color gradient for your surface
Select the depth range: select a continuous or step gradient
Custom depth range: set the depth range you wish to visualize in more detail
Hill shading: select the orientation and intensity of the hill shading effect
Strength: Determines how strong the shadows are.
Direction: Determines the cardinal direction of the light.
Altitude: Determines how far above the light is projected from.
Contour lines: select the interval of the contour lines. [coming soon]
The color legend widget shows the legend of one of the surfaces, the dropdown menu at the top can be used to select which one.
