Hi Brian- Thanks so much for your help. That works, though I feel a little silly now because I am realizing the lat/lon the FAA provides with these is the corners of the entire map image, not the map itself (these maps have a lot of white borders around them, which is what I am trying to crop). I

Re: [gdal-dev] Re: cropping a tif with lat/lon

I am a newby too so I will share what I have learned lately. You can convert from one srs to the other using the cs2cs tool from proj.4 which is probably already installed if you have gdal. To test it I typed this lengthy command all cs2cs +proj=lcc +lat_1=44.34 +lat_2=46 +lat_0=43.66

Thanks Jean-Claude, that works -- in QGIS i can see the border I want to crop is -110270 89629 110288 -88560 -- but I guess what I am asking is if there is any way to do this programmatically.. i.e. automatically turn the lat/lon coordinates into these values. -Dan -- View this message in context

Hi there! Please forgive this terribly newbie question. Been searching all day and I just don't get it. I have a geotiff VFR image from the FAA with the following coordinates as reported by gdalinfo: Upper Left ( -143411.876, 94058.326) ( 78d44'4.05"W, 39d49'53.24"N) Lower Left ( -143411.87

The paths are taken care of by configure, and they are checked to be ok. I also tried with standard installation folders (/usr/lib/ /usr/include/ etc) but no difference. I did not compile, since configure fails. So I believe it must be some incompatibility with the GDAL configure script and the

Re: [gdal-dev] Re: dev-version of HDF4

when does the gcc you must have: -L/Users/knutfd/Software/hdf-4.2.5/lib in order to find the lib so you need to do before the compile: export LDFLAGS="$LDFLAGS -L/Users/knutfd/Software/hdf-4.2.5/lib" and obviously you are going to need the include files also: export CPPFLAGS="$CPPFLAGS -I/Use

Jonathan, I didn't quite get what your problem is. Do you get all the pixels set to 255? Also, you should probably check if you really want to burn the id value into the raster. On Wed, Apr 20, 2011 at 4:58 PM, wrote: > Hi, > > I read your thread on using gdal.RasterizeLayer() in Python to ras
