Comments on: GeoJP2K Makes Me Want to Stab Myself (or Where is WED)?

If we don’t support JPEG 2000 as a file format they’ll have to be done externally.

The original goal of supporting JPEG-2000 was to automate the process of using JPEG-2000 data so it “just worked”. But if it’s going to just work except for when it doesn’t work or crashes, then I don’t want to keep the feature.

The rest of the GIS world copes with Geo-JPEG 2000 by immediately converting it to GeoTIFF using one of a small number of programs and then getting on with it; Geo-JPEG 2000 has absolutely not replaced GeoTIFF as an interchange format. If we can’t get WED to support JP2 without crashing then X-plane users will have to convert files by hand.

No. Right now the failures are currently –crashing– WED, so we sort of have to fix that. 🙂

In reply to Ben Supnik. Are you saying those steps will be rolled/coded into a WED menu option or they'll need to be done externally?

Ben,

Will you allow WED to process the jp2 files that import without
failing and issue a warning that we have to manually convert those files that WED can’t process?

In reply to carrotroot. Unfortunately USGS doesn't provide with GeoTiffs anymore, so we have to go through this in the USA.

In reply to Quantumac. That might become the standard procedure. As of this morning the only bug we have with WED is crashes. And the crashes are in Geo-JPEG2K import.

In reply to Freddy De Pues. Wed 1.3 will automatically convert geotiff to a drapped pol, so you don't have to go through all of those steps. You just import the image and you're done. however I filed a bug because it doesn't work with images which lack georeferencing, such as pngs and desert.

At work I’ve used the open-source GDAL package to translate .jp2 files to geotiffs. I used “gdal_translate” to convert the “.jp2” into to a “.tiff” and then used “geotifcp” to merge the “.tiff” and the USGS associated “world-file” (I think it has a “.jpw” suffix?) into a geotiff.

Might try that bit of magic if your own magic is hitting a wall.

Perhaps my so-called ‘work experience’ over the .jp2 files could be something helpful. My Linux distro Ubuntu 14.04 can not perceive adequately any .jp2 files. When a file .jp2 will appear into a folder, I cannot to close this folder properly, because a few second later the folder closes itself. This is a BUG of Ubuntu, maybe, more precisely, is exactly. So I just deleted all jpeg2000 files.

Good luck.

In WED 1.2 (MAC)
Convert USGS JP2K into TIFFs using Contenta Converter.
Convert USGS JP2K into 2048×2048 PNGs with Photo Convert
Place one TIFF at a time in WED
Place the corresponding PNG
Eliminate the TIFF
Highlight the PNG – make draped polygon
Voilà.
