Technical note

What changes when you convert LOS to STEP

LOS is made of pixels and STEP 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 STEP container.

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 LOS 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

LOS to STEP Conversion

What are LOS files?

LOS (Longitude Seconds) is a grid file of NADCON, the North American Datum Conversion tool of the U.S. National Geodetic Survey (NGS). It holds the east-west part of the correction that moves coordinates from an older datum, such as NAD27, to a newer one, such as NAD83, and it is always used together with a file of the same name with the .las extension, which holds the north-south part. Each file covers a region, such as the conterminous United States, Alaska, or Hawaii, with a regular net of points, and every point carries a shift in seconds of arc. Surveyors and mapmakers used these pairs for decades to bring older maps and survey records into agreement with modern positions.
