Buongiorno, Good idea. Here you go, Nepal slope map, thanks again to gdaldem: URL for JOSM is: tms:http://imagery.openstreetmap.fr/tms/1.0.0/nepal_slope/{zoom}/{x}/{y} and for iD: http://imagery.openstreetmap.fr/tms/1.0.0/nepal_slope/{z}/{x}/{y}
And previous rendering, with hillshading computed with a vertical exaggeration of 3 times (on elevations multiplied by 3): URL for JOSM is: tms:http://imagery.openstreetmap.fr/tms/1.0.0/nepal_dem_x3/{zoom}/{x}/{y} and for iD: http://imagery.openstreetmap.fr/tms/1.0.0/nepal_dem_x3/{z}/{x}/{y} Best wishes, Jean-Guilhem Le 07/05/2015 12:59, piz a écrit : > wonderfull > and now why not to derive from the DEM a slope map? > > > > ~~~~~~~~ quote of the day ~~~~~~~~~~~~~ > “I'll make him an offer he can't refuse” > (Mario Puzo - "The Godfather") > > > -- In data giovedì 7 maggio 2015 00:28:06, Jean-Guilhem Cailton ha scritto: >> Hi, >> >> The same DEM rendering now covers all of Nepal. >> >> URL for JOSM is: >> tms:http://imagery.openstreetmap.fr/tms/1.0.0/nepal_dem/{zoom}/{x}/{y} >> >> and for iD: >> http://imagery.openstreetmap.fr/tms/1.0.0/nepal_dem/{z}/{x}/{y} >> >> Best wishes, >> >> Jean-Guilhem >> >> >> Le 06/05/2015 22:24, piz a écrit : >>> I was thinking about the same rendering but didn't know about USGS data >>> licensing >>> >>> I think that the DEM should be used for evaluating helicopter landing areas >>> >>> best >>> Roberto >>> >>> >>> >>> ~~~~~~~~ quote of the day ~~~~~~~~~~~~~ >>> "Yeah, yeah, life sucks and then you die" >>> (Bret Easton Ellis - Pat Bateman "American Psycho") >>> >>> >>> -- In data mercoledì 6 maggio 2015 20:42:16, Jean-Guilhem Cailton ha >>> scritto: >>>> Hi, >>>> >>>> Needing a DEM background for some task, I've prepared a rendering from >>>> the 30m SRTM DEM data made available by USGS for Central Nepal on HDX, >>>> and shared it as TMS it in case it could useful to others too.
