Once I had a good correspondence between new and old, I reversed the transformation, taking a modern elevation dataset and warping it into the space of the old map.

@mapbliss 2) Divide the lake prox raster by the sum of the two rasters; gives a 0–1 scale of how far you are along the path between the high and low points.

3) In PS, I flattened out the lake shapes, and then in Blender, I applied a little curvature to the ramp.

4) Done!

Saturday experiments: watersheds

@rgdonohue It depends on what you think of as "large scale" — but these maps I hurriedly prepared for a class years ago seem to have been effective (and are now being used by others).

About six years after I began it, I'm finally ready, and very pleased, to present Landforms of Michigan, a love song to my homeland. Please share with the Michiganders in your life; I hope it will mean something to them.

@run_for_funner Editing mostly consists of cutting out the parts where check names by either tabbing over to Wikipedia/QGIS or turning on an overlay of another map, which has the names. While these are part of the process, they break the flow I'm going for. #CreativeCarto

@TheMapSmith The noise, both before and after halftoning, is helpful. Otherwise things look a little too perfect and flat.

Print quality varies a fair bit. I'll be binding the best & 2nd-best copies into 2 atlases (the latter of which I hope to send on a world tour; stay tuned). I might bind the 3rd best set. It's not great, but unsure what else to do with it.

Me: "Let's do a quick, fun project about islands"

Me: *unnecessarily spends hours per map compiling and editing together data from USGS, Census, Wikipedia, OSM, mining data sets, satellite tracings, CanVec, local town maps, Google, etc. into the most comprehensive possible map*

Decided to make one more, of the predecessors to NBC: the first "broadcast chains" connected by telephone and telegraph wires.
