I have downloaded elevation data from EU-DEM
My background is in software engineering and my GIS skills are limited.
How can I convert the aforementioned geotiff to WGS84 format geotiff with lon/lat values and altitude in meters.
I tried using QGIS "called warp command from the menu on the original file" however the converted lon/lat don't match with i.e. google earth as well as the altitude values definitely are not in meters.
Expanding my workflow as requested:
Ultimately I want to import and display elevation and other GIS data in an application made in Unity3D. My working environment is Windows.
The steps I followed are:
Convert specifically the "eu_dem_v11_E50N10.tif" (roughly the area convering Greece) file from QGIS with warp with the following settings:
Source CRS: empty
Target CRS: EPSG:4326 - WGS 84
No data value: default 0.0000
Output file res: default 0.0000
Resampling: Nearest neighbour
Advanced params: default
Output data: float32
Georeferenced extends: default
CRS of the target raster: default
Tried to read the file and display the elevation in a Terrain object within a Unity3D project using the library libtiff.net (Maybe here is the problem as I cannot read the heights correctly)
First issue is that, from my inexperience with QGIS, I did not find a way to find the altitude within QGIS of a lon/lat point.
Second issue is that using the gdalinfo on the generated file, the origin(lon/lat) is wrong as in the original the origin is located north of Brindisi in Italy whereas in the converted the origin is located roughly between Bari and Taranto, resulting in reading wrong altitudes
