Re: [gdal-dev] How do I get lat long extents from this Ogrinfo output on a .shp?

Steve, Thanks, that works wonderfully! I figured the other data in the file was UTM as well, but I'm only using the extents in my program, which is why I focused on them. +Paul Paul Dante Software Developer - Geodisy Walter C. Koerner Library | UBC Library The University of British Columbia

[gdal-dev] Static/Dynamic datum problems

2019-06-20 Thread Cameron Shorter
Hi folks, Our Australian spatial data users are about to face a systematic mismatch challenge when trying to use multiple static datums (GDA2020, GDA94) with the dynamic datum (WGS84). At the moment, it is government agencies grappling with the problem, but it is about to become a mainstream

Hi Paul, Its not just the extents but all the data in the file is in a UTM projection. You can reproject the file to WGS84 and then ogrinfo will report in long-lat. ogr2ogr -t_srs EPSG:4326 OldStreamsPolyline-wgs84.shp OldStreamsPolyline.shp ogrinfo -so OldStreamsPolyline-wgs84.shp

[gdal-dev] How do I get lat long extents from this Ogrinfo output on a .shp?

2019-06-20 Thread Dante, Paul
I ran ogrinfo on a shape file and got output. How do I convert the extent listed below into lat long coordinates? It looks like the units are meters, but I’m not sure how that will translate to lat long for creating a bounding box: INFO: Open of `OldStreamsPolyline.shp' using driver `ESRI

[gdal-dev] Is there an easy way to clip an image to the realdata?

Hi, I'm working with VIIRS L3U images of L2P (level 2 patches). The L3U data is gridded to the +-180 x +-90 but the patch only fills a small percentage of that. I'm compositing a the patch for a day using a vrt. Performance is an issue because all the patches cover the whole globe instead

[gdal-dev] Getting all known coordinate systems.

2019-06-20 Thread Franik
I am updating to GDAL 3.0 (C# bindings). I need a list of all the supported coordinate systems in my application. In the older versions, I requested all the known coordinate systems by reading the csv files in the GDAL_DATA folder (pcs.csv, gcs.csv,...). In the the new version, the csv files
