Technical note

LAN to JXL: what carries over and what does not

LAN carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. JXL has nowhere to record any of that. The picture transfers intact, the location does not, so the output cannot be dropped onto a map afterwards without being placed by hand. Keep the LAN original if the data still has to go back into a GIS. LAN stores pixels without compression loss and JXL does not, so this is a one-way step. Choose a high quality setting, and avoid converting the same file back and forth, because each pass compounds the artefacts.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see LAN data has GIS software. reaConverter renders it to JXL for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to JXL with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

FAQ

LAN to JXL Conversion

What are LAN files?

LAN is a multiband raster image format of ERDAS, used by the 7.x generation of the ERDAS image processing software, which was later replaced by ERDAS IMAGINE and its .img format. It became widely known as the format for Landsat Thematic Mapper satellite scenes, in which the same area is recorded in several spectral bands, such as visible light and infrared. A file of this type contains all the bands of a scene together, preceded by a short header with the image size and other basic information. The format was widely used in remote sensing, forestry, and land-use mapping, and many programs can still read it today. Its sibling, the .gis format, holds a single band of classified data, such as a land cover map.
