[Therion] LIDAR porvrch

15 Jan 2018

      Ahojte,
hram sa s lidar datami a mam trosku problem. neviem ci som sa dostal na
obmedzenie therionu alebo robim nieco zle.

vstupne data som mal stvorec
48.99146, 19.67295
    48.98282, 19.68312
vo formate tif, ktory som konvertoval cez gdal na txt - ArcInfo Asci Grid

gdal_translate -of AAIGrid zlomiska.tif zlomiska-povrch.txt

cez gdalinfo som zobrazil  taketo hodnoty:

z nich som sa pokusil vytvorit* surface.th <http://surface.th>.*

encoding  utf-8
surface
*  cs utm34*
*    grid 403129.72 5426310.22 0.5 0.5 1118 2310*
  input zlomiska-povrch.txt
endsurface

netusim ci mam spravny grid, tak ak sa dakto do toho vyzna prosim
skontrolujte pretoze pri kompilacii dostanem chybu..

*error -- lidar/zlomiska-povrch.txt [7] -- line too long*
*writing xtherion file ... done*

7- je riadok kde zacinaju vyskove data..(riadkov je 2310 )

S pozdravom
