Happy #MapInfoMonday
Today we will dive a bit into the world of raster again and look at how you can use hill shading to bring out specific features in your raster.
Hill Shading creates a hypothetical illumination of your raster by specifying the position of a hypothetical light, for example, the sun. This position is given by the direction from where the light is coming and the height from where it is coming.
The typical direction is North-West (315 degrees) and a height of 45 degrees. This can be changed to help bring out other features in your raster.
Below is a dynamic GIFF showing the change that different directions can have on your elevation raster. The GIFF starts from a Northern direction, goes via East and South, and ends up coming from a North-Western direction. The GIFF holds 8 different directions in total.
Let's start from the beginning. Here is an example of a raster grid where the Hill Shade has been turned off. If you select the elevation raster grid in the Layer List, you can find the Hill Shade control on the Style tab. It can also be found on the Raster tab.
