Map Data Workflow

Turn GIS data into something anyone can open

A map saved as JP2 opens on any computer and any phone. reaConverter produces those from GXT in batch, entirely offline.

  • Render every file in a folder to JP2 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

GXT to JP2 Conversion

What are GXT files?

GXT is a format associated with software developed by GeoConcept, a leading provider of cartographical information and optimization tools. GXTs are simple text files that can be viewed and edited with any regular text editor. Files with this extension contain feature descriptions, identified as "objects", and feature types – "type/subtype".

What are JP2 files?

JP2 or JPEG 2000 is an improved version of JPEG, one of the most popular file formats for storing and transferring images. Compared to the latter, JP2 image files offer higher quality and smaller size images by using a different compression algorithm, which can be either lossy or lossless. JP2s are created using the JPEG2000 Core Coding application, but can also be obtained through conversion from other formats.
