Default 1:20,000 (20m interval) digital maps

are there any free (like ibycus) 1:20,000 w/ 20m interval (or anything better than 40m intervals) that are available for free for the BC region that can be used on hand held gps devices like a garmin? or is it possible to export the imapBC 1:20,000 TRIM maps onto a handheld gps device like a garmin? am i stuck with using imap or google earth as the interface?

I have heard digital TRIM will be free soon (within the next year) if it isn't already.

Check here for updates:

You can use any WMS client. Point it to openmaps.gov.bc.ca. More info on the VOC wiki: http://www.ubc-voc.com/wiki/Online_m...al_Basemap_WMS

Very cool!

I see that I need to spend serious time on the iMapBC tool. I really hate the fact that the mountain labels are colored brown on top of the brown/green base peaks. :P

I have two goals. First goal is to print out usable (1:20,000) maps w/ 20m contour intervals and UTM griding. The scale can vary a little but the 20m contour interval is critical for me. 40m contour intervals is woefully inadequate in such varied terrain as BC. Second goal is to get that information as a basemap onto my Garmin GPS as well.

I did manage to find the Free Products page here:

http://archive.ilmb.gov.bc.ca/crgb/products/free.htm

and more importantly the Raster Base Map 1:20 000 section which is TRIM based but I cannot seem to find the geoTIFF and the PDF UTM projection files.

Apparently the raster base maps are provided at no cost by Base Mapping and Geomatic Services through the Base Map Online Store.

I've managed to get 20m contour intervals from the Base Map Online Store application (by using no text contours) but the printing (i.e. save as PDF) only covers what I see in the tiny square window? Is there any way to save a pdf with a larger viewing window than that tiny square or is the only solution an arduous one -- taking screenshots of the areas that I'm interested in and then cropping and stitching them in together using some sort of Imaging/Paint application? There has got to be an easier way. I would also like to layer in UTM grid data if possible. UTM grid data helps me locate my position really easily and I can estimate distances really easily without having to constantly look at the edges of the map. With UTM gridding and variable sized area maps, I would be able to print out my own physical maps.

Is it possible to download the raster data so I can use it as a basemap for my Garmin GPS?

I've never tried to print anything larger than letter size from mapplace.ca, but I believe that as long as you choose your paper size properly and set it all up right, you can print larger areas at smaller scales. It also has the gov't lidar, which isn't the best, but often shows more detail than topo alone.

I use
http://webmaps.gov.bc.ca/imf5/imf.jsp?site=bc_basemap
and Oziexplorer, and Paint Shop. If you need a larger map, glue adjacent maps together with paint shop. Calibrate them with Oziexplorer, and it allows you to overlay a UTM grid.

The same code is now up on http://trail.brijn.nu. Test URL maybe do something completely different any time

Other than the above-mentioned government sites for 1:20000 BC TRIIM maps, you can find the maps on Geokov.com (http://geokov.com) along with 1:50000 topo Canada and the regular Google maps/3D Earth. It has US 1:24000 topo and DOQ images also in USA section.

First need to drill down to a subregion page and from the top of google maps choose one of the desired map types. You can download the google earth plugin when prompted to view GE in the browser window.

In terms of gridlines, you can add both lat/lon and UTM. The UTM looks much better on google earth since you can see the numbers. But on other map types have to click the center and icons to find the UTM coordinate. I guess after printing, can find some UTM coordinates and write them on map.

Printing is easy to send to printer or pdf. Or if you want image can printscreen and paste in another application. The printed maps from main page with trails are small so might have to print two/three and stitch. The map accessed from "Plan a route" page is larger and prints larger but won't have the trails. You can plot your own trail.

Other goodies are conditions (weather, road, avalanche, etc.), condition info exchange and trails/huts/icons (need to click on them for name and info).

I found the test-trail.brijn site gave some greatly quality views which can be printed.
