Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to STEP 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.

reaConverter has been a huge time-saver for our team. We regularly work with CAD models in STEP format, and converting them to images or other file types used to be a hassle. With reaConverter, the process is fast, accurate, and incredibly easy to set up. The batch conversion feature is especially useful when handling large projects. Highly recommended for anyone dealing with STEP files on a regular basis.

FAQ

LAS to STEP Conversion

What are LAS files?

LAS (Latitude Seconds) is the file extension of grids used by NADCON, the North American Datum Conversion tool of the U.S. National Geodetic Survey (NGS), to convert coordinates between older and newer datums, in particular from NAD27 to NAD83. It stores, for an area covered by a regular net of points, how many seconds of arc the latitude of each point has to be moved. Longitude has its own companion file with the .los extension (Longitude Seconds), and the two always work as a pair. Separate pairs exist for the conterminous United States, Alaska, Hawaii, and other regions. The same extension is also used by LiDAR point cloud files, which are unrelated, so the context of the file matters.
