finally my 2 cents: with the sextante toolbox you can do some of that stuff in OJ as well. At least I used Sextantes contouring functions on (pseudo) DEMs to create home range polygons for animal movement data (with the HoRAE toolbox for OJ).
However, when I prepared recently maps with hillshade and color ramps for TileMill (i.e. for our web maps) I used gdal as well and followed those instructions: http://mapbox.com/tilemill/docs/guides/terrain-data/ except that I adjusted the color ramp for our area. ...In case Jukka hasn't seen it yet - though I bet ;) cheers, stefan Am 29.11.12 07:04, schrieb Rahkonen Jukka: > Sorry, I forgot to say that by "that tiff file" I was meaning the file I > downloaded from > http://srtm.csi.cgiar.org/SRT-ZIP/SRTM_V41/SRTM_Data_GeoTiff/srtm_40_01.zip > > It may or may not be similar to what Praveen Sinha was meaning. > > -Jukka- > >> -----Alkuperäinen viesti----- >> Lähettäjä: Rahkonen Jukka [mailto:jukka.rahko...@mmmtike.fi] >> Lähetetty: 29. marraskuuta 2012 11:54 >> Vastaanottaja: 'OpenJump develop and use' >> Aihe: Re: [JPP-Devel] problems with old image loader >> >> Hi, >> >> That tiff file is a 16-bit grayscale image.
