Bones.
Recentment les descàrregues de models d'elevació de terreny del IGN han passat a ser en un format diferent al ASC que es feia abans.
Pregunta:
Com ho puc fer per introduïr mapes d'elevacions en aquest format??...
Merci

  Thank you so much!... I'll try with QGIS... but TwoNav must work to make possible the transformation of the archive from LAND... =)

  Hello,

  You must convert from one format to another with a GIS tool, you will find documentation on the subject by asking the question in the Google search engine.

  You have QGIS which is a free universal tool like Swiss army knife which allows you to manipulate raster relief tiles: Merging, Cutting, datum format conversion, extraction of curves, etc.

  A little individual investment, reading tutorials, will be necessary.

  For example, the relief of this map, displayed on the GPS screen, comes from a database and converts into curves via QGIS
