Technical note

What changes when you convert HGT to DWF

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. DWF 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 HGT 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 HGT does not survive as colour in the DWF.

Map Data Workflow

From map data to a working drawing

Converting HGT to DWF usually means handing GIS data to someone who works in CAD. reaConverter makes that hand-off without a GIS seat on either side, for one layer or a whole delivery.

  • Convert every layer in a folder to DWF 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.

Compared to Autodesk's own conversion tools, reaConverter delivered faster DWF-to-DWG results without a single corrupted file — critical for our firm’s archive project.

I needed to extract text and dimensions from DWF files for a bill of materials. reaConverter's output to SVG gave me clean, scalable graphics. I was able to import them into Inkscape and extract all measurements. A lifesaver for reverse‑engineering work.

FAQ

HGT to DWF Conversion

What are HGT files?

HGT (short for height) is the file extension of elevation data from the Shuttle Radar Topography Mission (SRTM), a NASA mission of 2000 that mapped the terrain of most of the world, from about 56 degrees south to 60 degrees north. The data are cut into tiles, each covering exactly one degree of latitude and one degree of longitude, and every tile is a separate file. The name tells where it belongs: for example, N20E100.hgt covers the area from 20 to 21 degrees north and from 100 to 101 degrees east. The file itself contains only the heights in meters, with no other information. The data come at two levels of detail, about 90 meters per cell and about 30 meters per cell, and they are in the public domain.

What are DWF files?

DWF (Design Web Format) is a file format associated with Autodesk and its function is mainly that of facilitating the transfer of information related to a design project. As opposed to DWG files, the proprietary format of AutoCAD, DWF are more compressed and smaller in size. They can translate complicated structures related to architectural designs or engineering into a series of sheets that are easy to view and print.

Can reaConverter convert HGT to DWF?

Yes! reaConverter instantly converts .hgt to .dwf 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. For HGT to DWF it replaces the usual detour through QGIS, ArcGIS or ogr2ogr: add the files, pick the output format, and the whole batch converts offline. Surveyors, planners and engineering teams use it to pass data between GIS, CAD and everyday document formats.

Why choose offline conversion with reaConverter?
