Would make more sense from a business P.O.V. to make it two maps as you can sell the same maps (sorta) twice for little additional work.
I'm thinking that there would be quite a bit of extra work (and cost) as I would have to purchase and process an entirely separte scene captured during the early spring to get the snow line, winter features, etc.
Do you know of others who have created 'winter season' maps? With a winter scene, I guess one could keep the outlines of the glaciers for reference, however, the navigational aids on the map would be pretty sparse... not sure how that would go over with the skiing crowd.
Would love to see any examples - if anyone knows of any.
Did you perform the classification yourself?
Yes, I do a lot of remote sensing work with various spectral satellite platforms (along with ASTER and the likes). The classification that you refer to is the result of a process that starts with ER Mapper and ends in Photoshop (for cleaning up extraneous pixels and to apply the land use tinting / textures). There's a few remote sensing tricks I use to get rid of the shadows and merge the Pan band, etc.
Did you consider generating a new DEM from the TRIMM data?
Yes I did until I found out that there are massive intellectual property fees attached to using the TRIM data (that's over and above the $200 fee per 1:20k mapsheet - of which I need several). Strangely enough, the CDED data is based on TRIM and is in the public domain. Like we say in Canada - "No brainer, eh?"
How you gonna get this thing printed? 4, 5 or 6 colors? (something to keep in mind when picking those glacier isoline weights and color) Any printers in mind?
This will be the first map I get printed / published - so, that said, I'm quite illiterate when it comes to colour separations, etc. Any advice here would be much appreciated. What I'm counting on is getting advice from a local map publisher who's put out tons of maps (ITMB). In terms of a printer, we've got a place called Hemlock Printers - supposedly higher-end stuff goes there - I'm still a bit in the dark.
I've uploaded a little map browser applet on our website that has a more saturated version of the land use classification without the isolines so you can get a better feeling for what the image looks like - hopefully the resolution is high enough to make sense.
