Lasercut Stained Maps

Fall 2021

I’ve always found lasercut topographical maps to be extremely fascinating, yet simple pieces of art, and so in Fall 2021 I decided to go about making my own. The process is quite simple, only requiring topographical data (the hard part), a laser cutter (the less hard part), and wood (the easy part).

I start by finding topobathy (topographical and bathymetry) data which is used to generate layer heights. Websites like ArcGIS provide this at a cost, but depending on the city or region, if common enough, the following websites provide good alternatives:

With the raw elevation data, I use QGIS which is a free, open source, map processor to define my discrete layer heights. The layer heights are not uniform, since this generates a more aesthetically pleasing piece. I can then export that data as contour lines and layers to a vector image processor (I use Inkscape for Mac) to generate dxfs for laser cutting. Finally, I use nesting software (DeepNest) to create efficiently spaced sheets for lasercutting. Here is an example from a UK Map.

Once the dxf is ready, I lasercut approximately 1/8” thick pieces of Baltic Birch plywood, and stain the correct bottom layers. Usually, I will also lasercut a rectangle of the correct size as the base. I typically aim for 8 - 10 wood layers, resulting in a map about 1.5-2” thick. This is good for most frames.

I stain the bottom layers using dark navy blue wood stain, and then use a lacquer spray to protect the wood from moisture or other damage. Finally, I use wood glue and clamp together for about a day, making sure to scrape excess.

The last step is optional, but for me I like to frame my pieces. Framing can be quite expensive, especially for custom dimension pieces like these. I found americanframe.com and similar sites offer affordable frames custom dimensioned for pieces. Once framed, the piece is complete!
