Just in time for the first trillium blossoms of spring, the Forest Park map is ready for general use. This map went through several months of development and a couple months of beta testing. The current version of the map is v615 — if you have an older version, make sure to download the latest from
http://www.artofgeography.com/maps/fp/. How can you tell what version you have? The version number is a small notation on the right side under the title of panel 4.

I can safely say this is the best map I’ve made to date (although there are maps in the pipeline which may top this). Every aspect of my park map approach has been refined, improved, and tested.

Some notes on the map:

The technique for arriving at more accurate trail paths using LiDAR is described in an article I wrote recently.

One of the challenges of the Forest Park map is that the park is very long and skinny, yet contains over 75 miles of trails (see image to right of the park as it would look in a single panel).

I went to great lengths to ensure that the map would be usable by someone with just an average letter-size color printer. By average I mean a color inkjet printer that sells for $50-$80 (printers in this class can print at over 750 dots per inch, which should be fine for these maps). In order to ensure this level of usability, the map was broken into four panels, each of which is designed to be readable on a letter-size piece of paper (21.4 cm x 28 cm for European readers). One side-effect of straining every facet of the map layout to meet this goal is that the title/scale/compass information is not positioned in the same place on every panel.

If you wanted to make the map pages more portable, you could use double-sided matte paper and print panels 1 and 3 on one sheet of paper, and panels 2 and 4 on the second (that way you can still overlap adjacent panels). If you have an Epson printer, I find that Epson’s heavyweight matte paper works very well for this map, and recommend printing (in the print dialog box) with the highest quality setting that is available for the paper you are using. Printing the maps in black and white won’t work very well–there’s too much information which is designed around color.

One goal of the map was to facilitate using public transit to access the park. So three MAX stops are shown, as are bus stops along the eastern edge of the park. The Trimet bus-stop (and stop IDs) are not shown for every single bus line in the map extent, as it would overwhelm the map with transit info, most of which would not be relevant.
