Re: [gdal-dev] Considering drivers removal ?

I for one am using the GMT vector driver for GDAL on a regular basis, e.g., for integration between GRASS GIS and GMT for cartography. I am grateful to the developers for their continued support for this driver. Thanks, Jed ___ gdal-dev mailing list g

[gdal-dev] gdalwarp: behavior of "mode" resampling with NODATA

2020-12-30 Thread Jed O. Kaplan
Working with GDAL 3.0.4 The behavior of “mode” resampling when NODATA pixels are present is not clear to me from reading the documentation. I guess there are two possibilities: 1) If NODATA is the modal value among the pixels under consideration, then the result is NODATA or 2) The modal value

Thanks for the help all. Using avcimport to convert the .e00 to binary coverages allowed me to convert to other formats in seconds. I should have thought of this. Thanks again, Jed > On 13 Oct 2020, at 07:02, Even Rouault wrote: > > > Another option is to use QGIS to convert it. > > That ma

[gdal-dev] ogr2ogr: debugging slow performance when converting .e00 to other formats

2020-10-12 Thread Jed O. Kaplan
Hello all, I am new to this list, apologies if this type of question has already been asked. I’m using GDAL/OGR version 3.0.4 on a brand new server with 256GB ram. I have a moderately sized (~110MB) .e00 file I would like to convert to another format. The original file appears to be clean; ogri

[gdal-dev] Support for QSC in GDAL (was: Warp API / gdalwarp: using projection supported by PROJ4, but not explicitly by GDAL?)

2014-11-10 Thread Jed O. Kaplan
Dear GDAL developers, I would like to resurrect this thread from a couple of years ago regarding GDAL support for the Quadrilateralized Spherical Cube (QSC) projection in GDAL. Now that the QSC projection is supported by proj4 and works well, would it be possible to have the projection fully su

2014-05-02 Thread Jed O. Kaplan
Dear All, I have added the “Times” projection to my private copy of proj4 and tested it. It works properly using proj and unproj. Could anyone on this list maybe give me a little guidance as to how I can make GDAL aware of this new map projection so that I may use it with GDAL/OGR utilities?

Dear Dmitriy, Thanks again for your reply. I think you are right, there is support in GDAL for the Times projection, but the projection itself needs to be defined in proj4 somehow. When I try to run ogr2ogr with a simple world coastline file and project it into the Times projection using the wk

[gdal-dev] "Times" projection in GDAL

2014-03-24 Thread Jed O. Kaplan
Dear GDAL gurus, I have some scanned maps in the “Times" projection that I would like to orthorectify using gdalwarp and other GDAL tools. It appears that this projection is not supported in the version of proj4/GDAL that I have, though it seems to be included in most ESRI software (http://hel
