Technical note

MRF to HPG: what carries over and what does not

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 an MRF 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 MRF does not survive as colour in the HPG.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see MRF data has GIS software. reaConverter renders it to HPG for a report, an email or a slide, and handles a whole folder in one run.

  • 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.

FAQ

MRF to HPG Conversion

What are MRF files?

MRF (Meta Raster Format) is a format for very large images, such as global satellite mosaics, that was developed at NASA's Jet Propulsion Laboratory to serve maps to web browsers quickly. The picture is divided into many small square tiles, and the tiles are stored at several levels of detail, from the whole image at full resolution down to small overviews. A viewer needs to load only the few tiles that are visible, which makes it practical to browse images of enormous size. An MRF dataset is made of three files: a small readable file with the .mrf extension that describes the image, a data file with the tiles, and an index file with the .idx extension that tells where each tile is. NASA uses the format for its Global Imagery Browse Services, and Esri has helped to develop it further.

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.
