Technical note

How GTI and GIF differ in practice

GTI holds no pixels of its own. It is an index: a list of other raster files plus instructions for mosaicking, clipping or rescaling them, so it converts only when every file it points to is present at the path it records. A GTI copied to another machine on its own produces nothing usable. Converting to GIF renders the assembled result into one real file, which is often the whole reason to do it. GIF stores a limited palette rather than full colour, so the conversion has to reduce the number of distinct colours. Photographic content shows this as banding, while flat graphics and icons usually survive it untouched.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to GIF with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Stamp a text watermark, such as a project name or a date, on every image
  • 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

GTI to GIF Conversion

What are GTI files?

GTI (Raster Tile Index) is a small file that turns a large collection of map or image tiles into one seamless virtual picture. Instead of storing any pixels, it points to the individual raster files, which may be aerial photographs, satellite scenes, or terrain tiles, and describes where each of them lies on the map. A program that opens the GTI file sees one continuous image and loads only the tiles needed for the visible area, which makes it practical to work with archives of thousands of files without merging them first. The format appeared in 2024 and is stored as a short XML file with the .gti extension, or as a tile index in a GeoPackage or FlatGeobuf file.

What are GIF files?

GIF (Graphics Interchange Format) files are widely popular due to their ability to store animations and images in a relatively small size. Their compression algorithm implies the use of a limited color range (up to 256 colors), which means GIF files are great for storing static and animated images of a small size — like logos, icons or avatars, especially if you plan to transfer them or upload them online. GIF images, however, are usually not suitable for high-quality image rendering or printing.
