I would second configuring GDAL with thread support by default if pthread library is available, and turn it off only when --without-threads is explicitely passed. This would be consistant with how proj.4 works for example. Le lundi 30 août 2010 18:56:26, Dane Springmeyer a écrit : > In the Mapn

Volker, Pardon the late reply I was out of town for a few days. The libkml driver will read properly formatted schema and extendedData, but if I recall the kml driver does not produce properly formated schema so this may not be readable without editing. Feel free to submit a ticket on the libkml

RE: [gdal-dev] ArcGIS 10 and GIO driver

2010-08-30 Thread Jason Roberts
Matt, Donno if you are still working on this problem (I've been on vacation) but here is one possibility. If the GIO driver uses ArcObjects, it might need to call this new "LoadVersion" function before making any other ArcObjects calls. I had a C++/ATL ArcObjects program that worked fine with 9.x

[gdal-dev] default to 'interleave=band'?

2010-08-30 Thread Vincent Schut
Hi, is there a way to have gdal (utilities and library interfaces, notably python) default to band interleaving instead of pixel interleaving when writing geotiffs? I know this changed some time ago, but I'd rather have the old behaviour as many of my scripts are based on delivering max perf

The recently released 4.1 SDK update now supports an alpha channel for ECW. This is used to get around the speckle problem. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/gdal-dev-ecw-speckling-in-no-data-area-tp5465609p5477914.html Sent from the GDAL - Dev mailing li
