[gdal-dev] GDAL appears to ignore NoDataValue

2012-02-28 Thread Ophir Yoktan
I'm trying to build a mosaic, and I rely on the NoDataValue feature to treat some parts of the image as transparent. However, it appears that GDAL doesn't work as expected. I also created a very simple test case using a vrt dataset and gdal_translate - and I get the same results (that is - the 2nd

[gdal-dev] Issue converting GRASS data to GeoTIFF

2012-02-28 Thread Aldo
I searched for this issue, but could not find anything. I have 3 data sets that are in GRASS format (cell, cellhd, etc). I used GRASS 6.4.2 to convert the GRASS data into GeoTiff using r.out.gdal. The command looks as follows: r.out.gdal input=japan@japan output=japan.gtif I read the japan.g

Hey Michael, Good tips on the GDAL/MapServer combo. I may have a look into such a setup for comparison purposes. At the current moment though, I am in need of a solution that uses ArcGIS Server as the cache that I create will eventually be incorporated back into existing tiled services hosted on

Knut-Frode, I've skimmed quickly through the driver code and if you are lucky, it is probably just a matter of changing a few lines (well, I can be wrong). If you have a debug build of GDAL, you can first try to run "gdalinfo --debug on avhrr_20120227_235800_noaa19.hrp" . My guess (based on http:

[gdal-dev] reading NOAA-19 AVHRR

2012-02-28 Thread Knut-Frode Dagestad
Hi, The GDAL AVHRR driver seems to work only for data from the older NOAA-9 - NOAA-17 satellites: http://gdal.org/frmt_l1b.html Hence it does not work for my NOAA-19 AVHRR files in HRP-format (from Eumetcast), which have filenames like avhrr_20120227_235800_noaa19.hrp I have not able to fin

It turns out that the issue was not related to ogr2ogr at all, the translation worked fine. The problem was two issues, first I was using putty to access my server to run ogr, you need to have the character set to be UTF-8 and have a font that supports the characters. The second issue was that QG

Murat, I see that your view, lineview, doesn't give the expected geometry type with ogrinfo. It is showing the datatype as Real. Check if the datatype of geom is actually string/text. On Tue, Feb 28, 2012 at 12:49 PM, Murat Beyhan wrote: > Chaitanya, > > > Map file which is try to draw line as
