About JPEG 2000
Map of Abil in JPEG 2000: 100% green areas — in the WGS 84 coordinate system, units are meters.
Which layers are in the file
This file for the selected area contains:
- Water
- Greenery
Geometry by layer
- Water — drawn as filled pixels
- Greenery — drawn as filled pixels
What the file carries
The JPEG 2000 file for Abil: layers are flattened into one picture: objects become pixels and cannot be selected separately, OpenStreetMap tags are not kept — geometry and styling remain.
File size
The expected size of the JPEG 2000 file for Abil is about 2.1 MB; the exact size depends on the chosen layers and area.
Coordinate systems
WGS 84 (EPSG:4326), selectable in the wizard
Units
Meters (projected in the chosen coordinate system)

How to use JPEG 2000 for Abil
- QGIS (free) — Layer → Add Raster Layer; the JP2OpenJPEG driver ships with GDAL and is already installed.
- GDAL — gdalinfo map.jp2 shows the dimensions and resolution levels, and gdal_translate converts the file into GeoTIFF or PNG.
- ImageMagick or IrfanView with a plugin — viewing and batch conversion on the desktop.

FAQ: JPEG 2000 for Abil
Does this JPEG 2000 hold multiple spectral bands?
No. The exporter outputs an ordinary raster RGB image of the map. Multi-band satellite scenes (Sentinel/Landsat) are a separate satellite GeoTIFF scenario.
Can I get a lossless .jp2?
Yes, the exporter supports lossless mode via reversible wavelet. By default it uses lossy compression for compactness.
How do I open .jp2?
QGIS, GDAL tools, ImageMagick and dedicated ECW/JP2 viewers all open the format without trouble.
JPEG 2000 or JPEG XL — which should I choose?
JPEG 2000 is older and entrenched in professional archives, GIS tools and medicine: it is read by QGIS, GDAL and specialized viewers. JPEG XL is younger and compresses more efficiently, but software support is still narrower. For a GIS environment take .jp2.
Is there georeferencing in the file?
The export delivers a raster snapshot of the map. If you need a georeferenced raster that lands in its own place in a GIS by itself, take GeoTIFF or COG — there the georeferencing is written inside the file.
