Technical note

How LAN and STP differ in practice

LAN is made of pixels and STP 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 an STP container.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to STP 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 STP 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.
