High resolution elevation data and formats

[feeblebrox]

Hello!
Im trying to find a way to use my high resolution elevation data i Locus. I have tried to convert my .asc-files to .hgt, but i seem to loose alot of data. My 2 meter grids turn into 30 meter grids. Is there any way to use another format that can handle those resolutions? Maybe anyone tried and found any solution or workaround regarding the srtm format?
