Maps with Digital Elevation Model (DEM)

Information: a Digital Elevation Model is a file which contains information about land height in each point of the map. Garmin maps format can include a DEM, so that a hill shading like in the image below can be shown.

It is also possible with a DEM to see maps in 3D on BaseCamp and devices with such option (Oregon 600 for example).

Additionally, maps with DEM are able to calculate vertical profil of routes created in a computer or in a GPS device (if the model has such capability).

I'm tryng to install DEM map of Costa Rica. But also in this case I'm not be able to install.
The program install show me:
c:\ProgramData\Garmin\Maps\OpenStreetMapItalyDEM.gmap
I don't change the directory but after the installation in this directory I'can't find anything.
Thank you for the answer that you will give me.

Hola. Estoy usando estos mapas en OruxMaps, visualmente son fabulosos. Tengo una duda: Descargue ColombiaDEM pero no veo diferencia alguna con el Mapa Base. No veo el sombreado de las colinas. Hay algún impedimento para verlos en OruxMaps?
Gracias
Admin:
La verdad es que no lo he probado, pero seguramente OruxMaps no "lee" la capa que contiene la información sobre alturas del DEM, necesaria para diburar el sombreado. Creo que si consultas en algún foro de OruxMaps o a su desarrollador te podrán confirmar.

Hola.
Yo uso OruxMaps con DEM en formato .hgt y DEM + Hdr, con estos archivos puedo sombrear los MapsForge y los gmapsupp.img. y puedo imitar o emular el sombreado de Garmin visto en la imagen de arriba. Pero el resultado es algo más tosco.
Los Topo muestran perfectamente las curvas de nivel.
