Technical note

How MPL and GBR 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. GBR 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 MPL 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 MPL does not survive as colour in the GBR.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to GBR 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

MPL to GBR Conversion

What are MPL files?

MPL is the map list file of ILWIS (Integrated Land and Water Information System), an open-source GIS and remote sensing program developed at the ITC in the Netherlands. A map list is a way to group several raster maps that belong together, such as the spectral bands of a satellite image or a series of maps from different dates. Instead of holding the pictures themselves, the file records the names of the raster maps in the list and the georeference they share, which ties them to places on the ground. Grouping the maps makes it possible to process all of them at once, for example in classification or time-series analysis. The raster maps themselves are saved in separate files with the .mpr extension.

What are GBR files?

GBR is part of the Gerber group of formats — a set of standardized extensions used in the printed circuit board (PCB) industry. Gerber files include 2-D representations of various PCB images, such as copper layers, solder mask etc. They can also describe the electrical connections on such boards, or drilling and milling info associated with them. Similar formats include GBS, CMP and SOL.

Can reaConverter convert MPL to GBR?
