Re: [gdal-dev] Empty region after projecting GeoTIFF from 4326 to 102113

2013-03-07 Thread Frank Warmerdam
Jason, gdalwarp uses a sampling technique to figure out the region of the source image needed to produce each tile of the output image and this works poorly for transformation "interruptions" like datelines. Some warp options which have an effect are documented at: http://www.gdal.org/structG

[gdal-dev] Empty region after projecting GeoTIFF from 4326 to 102113

I have an RGBA GeoTIFF in EPSG:4326 with an extent that wraps the 180 decimal degree international dateline (western extent: 74.2 dd, eastern extent: 433.8 dd). When I attempt to project this image to either EPSG:102113 (as defined in $GDAL_DATA/esri_extra.wkt) or a very similar custom mercator pr

I don't understand this. The .hdr file is only created/recognized for EHdr datasets. AAIGrid datasets have both their header and samples in the .asc file and the .hdr file isn't used in that case. G. I know that too but 'head didn't think' and I just took it to be common to both formats (I
