Convert LOS to DXF

Online GIS converters cap file size and need an upload. reaConverter converts LOS to DXF locally, whatever the size of the dataset.

Online converters too slow for your LOS files? reaConverter works locally and handles unlimited batches. All processing runs locally on your PC, so your files stay private and secure. No command line and no scripting, unlike the usual ogr2ogr route.

Technical note

How LOS and DXF differ in practice

Geospatial coordinates are absolute positions on the earth, and they are large: a projected easting runs to six or seven digits, while latitude and longitude are small decimals. DXF expects a drawing laid out near its own origin in millimetres or inches. The geometry itself converts correctly, but it can land tens of kilometres from 0,0, or arrive at a scale where an entire county is forty units across. Zoom to extents first, then measure one known distance before dimensioning anything. A line in an LOS image is several pixels wide, so tracing it can mean different things and the mode is yours to choose. Centreline returns a single line running down the middle of each stroke, which is what a scanned drawing needs: one entity per line, snappable and dimensionable, rather than a long thin rectangle around it. Outline follows both edges and returns closed shapes, which suits clipart, logos and anything that will be filled or cut. A precision setting controls how closely the traced paths follow the pixel edges. One thing to plan for: vectorised output from this path is black and white, so colour in the LOS does not survive as colour in the DXF.

Map Data Workflow

From map data to a working drawing

Site plans, utility routes and parcel boundaries often start out as LOS and end up in DXF. reaConverter turns the layers into drawing entities in batch, so a full project folder moves across in one run.

  • Convert every layer in a folder to DXF with the same settings
  • Go the other way too, from DWG to Shapefile, when the GIS team needs the drawings back
  • Render the same data to PDF for a quick review copy
  • 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.

In architecture, sharing DXF files with clients is impractical. reaConverter lets me create universally accessible PDFs in seconds—no more awkward 'Can you open this?' moments during presentations.

Someone gave me a disc with a single .dxf file that just wouldn't open. After struggling with it, I consulted some tech-savvy friends who recommended reaConverter. The conversion took about 20 seconds flat, and now I can easily view everything in PDF format!

While one-time DXF to JPG conversions can be handled through online tools, daily or recurring tasks demand dedicated software. For over a year now, reaConverter has been my reliable solution—consistently delivering quality results without the hassles of cloud-based alternatives.

FAQ

LOS to DXF 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.

What are DXF files?

DXF (Drawing Exchange Format) is a format associated with AutoCAD, a popular program used for computer-aided design by engineers, architects and other professionals in the field of building design and construction. The DXF format was developed in the early 1980s by Autodesk with the purpose of increasing the interoperability between AutoCAD and other CAD or advanced image design programs. It supports 2-dimensional and 3-dimensional drawings, and can be opened using a wide array of image processing programs.

Can reaConverter convert LOS to DXF?

Yes! reaConverter instantly converts .los to .dxf with perfect quality preservation. With its batch processing feature, you can convert multiple files at once in just a few clicks. You can even convert images directly from Windows Explorer using the right-click menu — fast and convenient.

What is reaConverter used for?

reaConverter is a Windows converter for 800+ formats, GIS data among them.
