v2 SPS Tiles Posted
I’ve posted new tiles with the following changes:
Whiter glaciers/permanent snow with blue contour lines. I talked about this in a previous post.
Change forest color depending on density (only in Yosemite and Sequoia/King’s Canyon NP so far). I also mentioned this in a previous post.
Non-SPS peak names. Discussed earlier as well.
Pass names.
Trail names, mostly in the [...]

Fixing GNIS Data
I’ve been working quite a bit on adding non-SPS peaks to the map. It’s been a mix of learning some new skills and repetitive, tedious work.
This all started with California GNIS data. After filtering down to just the summits, I converted it to a shapefile and threw it on the map expecting it to work out [...]

Glacier Contours
I consider the USGS 7.5′ quads to be among the best topographic maps around. That said, working around their shortcomings is the primary cartographic motivation for Closed Contour. Right now I feel like I have a ways to go before I can claim that my maps are ‘better’ (how ever you define it) than the [...]

Mapping Challenges
I started working on this project about 3 weeks ago in my spare time. The first few days I spent just trying to make some pretty pictures with some basic data, maybe a DEM, some contours, some summits, etc. Once I convinced myself that what I had in mind was possible I began to work [...]

What is Closed Contour?
Simply put, Closed Contour is my attempt to create modern topographic maps using publically available data. Here’s what I’m after:
User-specific data. I’m into peak climbing and I want my maps to be focused on that.
Aesthetically pleasing. A topographic map should look good at every scale and viewing distance.
Editable. Ideally the map should be editable in a [...]
