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.
