Can you help me plan a trip to the Canadian Rockies?
Can you recommend a good day hike in the Canadian Rockies?
The most complete guidebook that includes descriptions of virtually every trail in the Canadian Rockies is the Canadian Rockies Trail Guide by Brian Patton and Bart Robinson. Local hikers consider this their “bible,” and most of us have at least one or two well-used editions on our bookshelves. This book and others are listed on the Canadian Rockies Guidebooks page.
Are Gem Trek maps available in digital format?
There are a couple of side issues that also pop up every time we look at the digital format question—the issue of scale (Gem Trek maps are at different scales) and the issue of continuous coverage (Gem Trek maps do not provide “seamless” coverage), both of which issues would require a significant investment of time to resolve.
Will you be making any new maps in the near future?
What are the copyright rules on Gem Trek maps?
I’m new to maps. What are the scales on maps and how do they work?
The terms “small scale” and “large scale” are somewhat subjective, but our driving maps are smaller scale (our Southwest Alberta & Southeast British Columbia map is 1:500,000), covering a larger area in less detail. Our trail maps are larger scale (many are 1:35,000), meaning they cover a smaller area but in more detail. Just remember—the larger the number the smaller the scale.
Are Gem Trek maps available for uploading into my GPS?
You can enter waypoints manually in your GPS. Or, if you have OziExplorer, Memory Map, or something equivalent, you can load a map of the area into your mapping program, click where you want to set waypoints, then “trace” the trail manually to make a track. When you are finished, upload these waypoints and the track into your GPS.
What do the blue numbers mean that are placed around the edge of Gem Trek maps? When using my GPS with my Gem Trek map in the field, what map datum should I select in my GPS set-up?
You can easily set your GPS to operate in UTM, rather than Lat-Long, similar to selecting kilometres rather than miles. To do this, with your GPS turned on, in the Main Menu page under “Setup” (on the Garmin GPS), select “Units.” On this page, for Position Format, select “UTM UPS;” for Map Datum select “WGS 84” (corresponds to NAD 83); for Distance/speed, Elevation and Depth, select “Metric.”
For background information on how the UTM grid works and how to define points on the grid (grid references or GR) check this webpage: The UTM Grid – Map Projections on the Natural Resources Canada website.
Why don't the UTM Grid References used in the Kananaskis Country Trail Guides synchronise with my Gem Trek map?
On Gem Trek’s Bragg Creek & Sheep Valley map, for example, to convert grid references from NAD 27 to NAD 83, on the Easting, subtract 80 metres and on the Northing, add 209 metres.
Depending on which Gem Trek map you are using, grid references on the Kananaskis Country Trail Guides will differ by about 200 metres. Or, a particular grid reference may not differ at all, if the edition is based on a NAD 83 government topo map. Unfortunately, when a grid reference is given in these books, the datum used is not noted.
If you have a GPS, you can figure out the conversion factor yourself for any Gem Trek map: With the map datum on your GPS set to NAD 83, choose a spot approximately in the middle of the Gem Trek map and enter the full UTM coordinates for that waypoint (not just the 6-number grid reference) in your GPS. Then set the map datum in your GPS to NAD 27. Write down the two different waypoints, then add or subtract to calculate what the difference in Easting and then Northing is in metres, and in which direction (east or west, and north or south).
How do I notify Gem Trek of a change or omission on one of your maps?
Please email us with as many specifics as possible. If you have the trail waypoints and a track from your GPS, save it as a .gpx (GPS Exchange) file and email it to us with the details.
