"Historic" layers are great addition. The Visitor layer gives access
to map sources that I used to go to Maplets to get -- NPS maps and
USFS maps. I'm excited. You ROCK!

P.S. I got the t-shirt.
> A user told us about the sources available atwww.caltopo.com, and we have

any way we can scan and send local maps to the server?

I'm the creator of caltopo.com and these map layers. The visitor map
was an experiment; I wasn't really sure how it would turn out or how
useful it would be. It's also more labor-intensive than the other map
layers - not only do I have to georeference each image by aligning a
few points with real-world coordinates, I have to crop them carefully
so that the extraneous legends on one map don't overwrite a
neighboring one. Someday maybe I'll find a high school student I can
pay to fill out the rest of the US for me, but until then, if you'd
like to see a particular map added let me know. If you can send me a
high-resolution TIFF and the real-world coordinates of a couple points
close to the corners (e.g. pixel 245,120 is at 39.2,-120.5), it makes
it that much easier on me, but it's not necessary.
Since I created the layers and my site doesn't compete with GaiaGPS,
I'll also note that you can print them at http://caltopo.com/map.html
(select the page size icon in the top right). Chrome will let you do
borderless prints, which is a great way to sneak a historical map or
topo of your favorite getaway through a large-format office printer
and onto a cubicle wall.
The USFS and historical layers are currently CA-only, but will be
going nationwide (where available) shortly.
