Technical note

What changes when you convert GTI to GLB

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 GLB renders the assembled result into one real file, which is often the whole reason to do it. GTI is made of pixels and GLB is a geometry format, so the two describe shape in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains usable geometry or a picture placed inside a GLB container.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to GLB 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

GTI to GLB 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 GLB files?

GLB is a binary file format, which contains 3D models saved in GL Transmission Format, and is a standardized format to share 3D data. GLB format can be used for free and is mostly used in science and engineering for doing complex analyses of landscape and 3D modelling. A GLB format is supported by all major 3D modeling programs.
