LESSON 4: Preparing Map variables on Dinamica EGO

Dinamica EGO provides a number of facilities for working with maps, including map preparation. It is possible to: re-project, create map cube, extract layers and rasterize a shapefile, among other functionalities.

In this lesson will you learn:

• How to rasterize a given shape file;
• How to create a Cubemap (multilayer map);
• How to re-project a map;

Which Functors will you use in this lesson?

• Create cub map
• Transform map
• Rasterize shape

We will use:
- The shapefile of Indigenous lands on Mato Grosso state

- The shapefile of railways on Mato Grosso state

- The shapefile of main rivers on Mato Grosso state

Let’s go!

Rasterizing a given shape file

Inicialmente carregue o functor rasterize shape (alocado na subpasta GDAL/OGR). Dê um clique duplo no functor e então a seguinte janela se abrirá: No campo Input shapefile name carregue o arquivo que queremos rasterizar, neste caso o shapefile of Indigenous lands on Mato Grosso state No campo Output file name, defina o nome do raster que será criado. (neste caso chamaremos de indigenous_land_raster).

The Optional Inputs podem ser melhor entendidos no link: Rasterize Shape

Creating a Cube map (multilayer map)

Where, we demonstrate how to create a cube map cointainning the 3 maps: Indigenous lands, railways and main rivers on Mato Grosso state. Grab and place on the sketch the maps 3 functores load map e carregue os arquivos Indigenous_lands, railways and main_rivers.

Click on the Map Algebra tab from the library window and grab a “Create a cube map” and place it on the sketch.
