There is one problem though, many of the "micros" are listed as small caches.




You are welcome to take the database and correct it for your definition of a micro. I didn't do a regional analysis but I would hazard a guess that the vast majority of micros are within the perimeter, and I do believe you have that covered pretty well.

Fascinating stats Dragonfreys! Thanks for sharing them with the rest of us .I found the density map of Winnipeg particularly interesting. I wonder now what a map of the home locations of cachers would reveal?? Where is the greater populace of cachers located and is there a direct correlation of cache placement density to cachers residences? That would be an obvious conclusion but is it so? Hmmmmm...

I did think about doing some sort of cacher statistics but there are a couple of problems with the data from the pocket query. First cachers can and often do modify the name of who placed the cache so it can be challenging to link caches to unique cachers. This could be overcome with some filters and merging of aliases but then the other issue is privacy. There are a number of geostatisical tools designed to determine where someone lives by their activities (crime analysis in GIS has come a long ways in the past few years) and in most cases it would be even easier with geocaching because of the requirement of cache maintenance. So I left individual cache density analysis alone, but I suppose another approach would be to look at regional densities and then determine the number of cachers by region and see if they correlate. MBGA has a classification for members in Winnipeg, rest of Manitoba, and outside of Manitoba, so we can see if those ratios mesh.

The density correlates strongly with attractive cache land. Large tracks of public land that has many hiding spots, mostly parks.

Pocket queries do contain the "placed by" name but it also contains the unique "owner id" and unique name.

      <groundspeak:owner id="234129">polarbeardiggers</groundspeak:owner>

Hmmm, must have missed that. Will have to check it out. It would be interesting to see how many unique hiders are in given areas.

Ah yes, I did think of running a park vs cache density analysis but didn't get around to it. I think it could be quite interesting and helpful for future hiders.

PostPosted: Dec 04, 2006 8:05 pm    Post subject: Hider Stats Reply with quote

Okay, thanks to Peter's tip here's the breakdown of hider stats. First a histogram of the cache placement by unique hiders. Note that you only have to place about 5 caches before you've placed more than 80% of other hiders in Manitoba.





Next is cache type by unique hider. The regional stuff may have to wait for another lunch hour. Note that these stats are only for caches placed in Manitoba and labeled as such (actually 6 caches are outside of MB but labeled as MB so there are included). Also one of the traditionals was actually a moving cache that ended up in Montana.

Anticipating the next question might be "What's the stats with active caches?" this was generated. Note the abreviated cache types T-Traditional, M-multi, U-Unknown/Puzzle, V-Virtual, L-Letterbox, E-Event, C-CITO.

Okay, took some lunch time to pop out a few more stats. Used the Regional Health Authority areas, for lack of anything better and did a quick spatial join of caches to regions. Here's the type of caches by region.





Here's a table showing the size breakdown by region. As expected Winnipeg is the micro capital of the province with 70% of caches being either a micro or small and the highest micro ratio in the province at 30%.





Cache hider ratios by region. Interesting that 1Queen&4Jokers and polarbeardiggers are the only two teams to have hidden caches in six different regions. I was going to do a further breakdown of Winnipeg by neighbourhoods but didn't get around to it.

I love stats - especially with visualizations. DragonFreys are my heroes!

My favorite so far has to be the cache density, kernel density grid analysis. It shows all the sweet spots. I think we can give some of these spots names.

There’s the strong caching communities of Flin Flon and Cranberry Portage, the nmrider spot in Swan River, the DragonFreys spot at Onanole, the collaborative effort to make Brandon a spot on the GeoCaching map, the GEO30G/S class’ excursions to the Brandon Hills spot and lap and abeja2’s busy hiding to make WinklerMorden and Carman GeoCaching holiday destinations. There’s also the relatively new The Redneck spot in Elm Creek, the kruzrrr zone around Portage la Prairie, the ginny212 party spot over Winnipeg Beach and junglehair & The Old Bat leaving there mark at camp Morton. And of course where it all started, the 1Q4J (along with their extended caching family, Explorer and Ramblin Rose and FreeS), hot spots in Morris and Steinbach.

The Provincial Government could take a lesson from Manitoba GeoCachers in promoting tourism in Manitoba’s vacation hotspot, The Whiteshell. Forget those expensive tour guides – just point travelers to GeoCaching.com.

And of course the really big hot spot created by a plethora of hiders that have placed a cache by every park, plaque, statue, historical monument, trail, or otherwise interesting location in Winnipeg, now a GeoCaching vacation destination.

My favourite is the Slippery spot over The Pas though :)

There is some nice blush developing around the party hotspot of St. Geneviève.

PostPosted: Dec 08, 2006 5:51 am    Post subject: Caches in Protected Areas Reply with quote

Well the provincial government recently updated their protected areas layer for Manitoba so out of curiousity I did some more spatial joins and came up with some more statistics for you stats lovers out there. Here's the map showing the types and general areas of protected public property in the province (there's a tongue twister).





Note that there are often provincial parks within provincial forests so caches may land in both, although technically the parks usually have higher levels of protection. Here's a table of protected areas and the number of caches by year placed in them. You can see which are favourite haunts of geocachers.





And here is the list of provincial forests that contain caches

I will try to send you a green spaces map for Winnipeg later today - With the very high density of caches in Winnipeg (of course compared to rural MB not NY) it would be interesting to see that distribution.  OK - Dradonfrys and I had an off line email about green spaces (parks/rec/just green).



I like the map of the protected areas - I see there is a cache at overflow (Blitzing "The Overflow") just north of the Lake Winnipegosis Salt Flats ecological reserve.  If you can get a map it might be useful to add that group of protected areas as well.



Thanks - Overall some cool maps.  Cache density at the RM level or nearest neighbour distances might give more rural cachers a better measure to use as the denominator for the Dani Ratio.

Now I read, re-read, and then was about to write how could the Turdle forget me when suddenly the print became clear. He didn't forget me, I just couldn't see the Forrest for the Trees.



Offers to Hot Wax any Turdle legs if he gets near my patch of Brush! And now I wonder whether the Dragon has my coin ready for me to pick up on Monday Morning when I go through? Grins...Y'll
