its not like the crappy bc basemap, it has contour lines and named creeks, lakes, peaks

The BC map also has 20m contours... though the iMapBC application seems to be spewing out way more of them than usual now, anyone solved this problem? Example:

Also, has anyone found a way to make the names of features not lose letters at different zoom levels (as in my linked map above)?

Good thing the old BC Basemap is still accessible!

The Online cadastre is also availabe....similar to BC base map only with more layers.

Interesting. Both the basemap and the casdastre map solve the lettering problem, but the cadastre has the same contour over-labelling issue.

I couldn't figure out how to add a UTM grid to either of them though, which is fairly essential. You can do that with iMapBC. If you know how to add them with the basemap, let me know.

Why does the government have sooooooo many different (yet very similar) mapping tools. Seems like they could just have more layers in one place...

different tools for different users.

i don't ever use the utm grid so i don't know how to turn it on on the basemap, but i'm sure you can do it if you try.

if you have problems with missing letters or overwritten contours, it's a sign you need to adjust the scale or the center of the map slightly to fix the problem.

Dru's right...it seems on the cadastre the overload of contours is because below 1:80000 scale the contours are for every 20m but over 1:80k the contours switch to 100m. So between 1:30k and 1:79k the map is a mess.

trail.brijn.nu has a feature to overlay UTM grids at the 1:20,000 level but it does lose placenames unless you drop down in resolution

I don't think you can. BC exists within multiple UTM zones - generally for a map to be "pannable" dynamically like Google maps you need to have a single map projection for the entire system - can't do that for all of BC accurately if you use UTM.

I believe they use BC Albers Standard Projection which is "Albers Equal Area Conic" rather than "Universal Transverse Mercator". I'm sure someone will correct me though, but AFAIK I think that's why most online maps don't show the UTM grids.

iMapBC is basically the same thing as the basemap, but it has an enormous number of layers. It is the recommended tool to use to make your own maps when you go to maps.gov.bc.ca or nric.ca.

You can easily add the 1km UTM grid to your map with iMapBC. Just click on layers, then "Add" and search for UTM. Add the "UTM gridlines 1:1000" layer. Getting, the lines labelled is a little bit more work, but you can click on the little colour symbol next to the layer and add an elevation label (instructions here: http://www.ubc-voc.com/wiki/Online_mapping)

Unfortunately the basemap doesn't have the "Add" button, so you are limited to the dozen or so layers they have given you.

Given that it is the same application, I don't see why they cant fix the name labelling, or the over-contouring. The contour overlabelling just started recently, it was never a problem before. Unfortunately adjusting the scale or the map centre doesn't really get rid of the problem at all, unless you drastically change the scale... then you lose the ability to make a custom map.

Maybe I'll send an email to the maintainer.

Got this response from the government:

Hi Scott -

Good to hear that you're using iMapBC regularly.

With regard to the contour labelling issue, we had a user report the
problem to us a few weeks back, and are working on 'taming' the contour
labels. That said, if you modify the symbolization for contours (the
little rainbow icon next to the layer), you can choose options to reduce
the number of labels (i.e. One label per name). The downside is you
currently loose the nice bolding of the 100 metre contour line.

The labelling problem has been considerably long standing. We have
different map 'engines' making the maps behind the scenes, and are
testing a newer 'engine' in the old BC Basemap that resolved the
labelling problem. We hope to bring this solution forward to iMapBC in
the near future.

I can't give you exact dates, as we have a large queue of items to work
on, but hopefully we will see resolution of the contours labelling issue
in the next few weeks.

Hope this helps,

Cheers,

I really appreciated this link martin, thanks.
I thought we had lost it, but it has just moved:

http://webmaps.gov.bc.ca/imfx/imf.jsp?site=bc_basemap

While I was poking around I found that an old link to openmaps now directs to here:

http://ilmbwww.gov.bc.ca/dm/wms/index.html

The basemap/TRIM link there lets you put contours and stuff in Google Earth.

The iMapBC seems so cumbersome compared to the basemap. I still get too many contour labels and such, although I wouldn't be surprised if it is just a matter of finding which of the dozens or hundreds of checkboxes to uncheck. To measure distances on iMapBC I need to load a layer that completely resets the view back to the default.

Another great resource is the GeoGratis website : http://geogratis.cgdi.gc.ca/frames.html

Among other things, it's got free federal-govt topo maps (1:50,000). It took a while to find my way around the massive site, but I eventually found and saved a copy of the central Stratcona Park area. I cropped out and enlarged my route (using basic photo editing software) and had a double-sided copy printed and laminated at my local print shop - all for less than 10 bucks.
