Other DEM file format ?

[routeconverter]

So, I can give you files for testing, but say to me if you prefer any projection (WGS84, or Lambert 93, or...), or only WGS84.
Do you prefer square tiles, or any rectangular size ? Do you prefer Interger16 data or is it possible to use Float type ? (I think float is better for accuracy).

Hi Bernard,

I'm still in the analysis phase – please consider my naive/stupid questions:

1. Why do you need a higher accuracy than 1" arc - which is a net of data points with data every 30m and a iinear interpolation between them?
   
2. How accurate are the position informations that you have? +/- 15m?
   
3. Are you aware that RouteConverter uses full meters to represent elevation?
   
4. Are you aware that RouteConverter by default strips exported longitude and latitude to 7 digits (configurable)?
   
5. Won't a GIS like @Nordpol suggested be a better choice for your requirements?
   

Looking forward to your answers
