Technical note

How GTIFF and HPG 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. HPG 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 a GTIFF 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 GTIFF does not survive as colour in the HPG.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to HPG 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 handles HPG files flawlessly. I use it to convert plot files to PDF for approvals, and the output is always accurate. The automation through Watch Folders and command-line is a big plus for speeding up our workflow.

Working in a print studio means constantly juggling obscure file formats. I used to waste hours Googling converters or installing random software — until reaConverter became my Swiss Army knife. Install it once, and you're set forever. No internet? No problem!

FAQ

GTIFF to HPG Conversion

What are GTIFF files?

GeoTIFF (.gtiff) is a georeferenced image format used for storing raster graphics with embedded geographic metadata. Common in GIS and remote sensing, it allows precise alignment with map coordinates, making it ideal for satellite imagery, terrain models, and aerial photography. GeoTIFF files are widely supported by mapping software and can be converted or edited without losing their spatial reference.

What are HPG files?

HPG is a vector image format created in a standard programming language called HPGL (Hewlett-Packard graphics language). Other extensions created in this language include PLT, HP2 and PL2. All are called "plotter files" and are created by drawing programs such as AutoCAD to be printed using a device specialized in vector graphics. An HPG file uses a line series of two-letter codes to render an image and can also include parameters.
