Latitude distribution of EarthCache finds:

 

The strong (northern) seasonal cycle of EC finds made me wonder about the north-south (latitude) distribution of EC finds. The following graph is the result:

 

ECfindslatitudedistribution.jpg

 

Only 2.4% of all EC finds are in the southern hemisphere!

 

50% of all EC finds are north of N48 57.120, in other words, north of the USA.

Finds vs. number of Favorite Points:

 

With FPs I am never sure which is the cause and which is the result, but the relation between the average number of finds and the number of favorite points is as follows:

 

ECfindsvsFPs.jpg

 

This is very close to a linear relationship - each FP is about 7.4 finds worth. (Or is it the other way round? <_< )

Favorite Point percentage vs. Difficulty & Terrain:

 

ECFPpercentagevsD.jpg

 

ECFPpercentagevsT.jpg

 

What this means is that for EarthCaches with a Difficulty rating of 1, there is a favorite point for 7.5% of the finds, or about 1 FP for every 13 finds. This increases to 1 FP for every 2.8 finds for a Difficulty of 5.

 

It looks like we are masochistic - we reward caches that make us suffer!

Just seems like a lot of weather related. I get few/no visits on many of my Earthcaches in the winter. The weather even prohibits many of them to even be done.

 

If you pulled them by caches north of the 37th or 38th parallel and I bet you get more dramatic seasonal numbers

Link to comment

Maybe if you graphed monthly finds on ECs between, say 20 and 40 degrees North, 40 and above degrees North, and likewise for 20 to 40 south and >40 south, and +/-20 from the equator and look at how the monthly finds compare. I'd wager for the >40 degrees north/south, there'd be a summer bias.

 

If I restate that more clearly, I'd be interested to see a comparison of monthly finds for ECs:

>40 degrees south

20 to 40 degrees south

20 degrees south to 20 degrees north

20 to 40 degrees north

>40 degrees north

or any other arbitrary values, such as 37 or 38 (instead of 40) suggested above.

 

Just if you have a moment... :)

 

Edit to add: It might even make sense, if showing the seasonal bias) to show number of monthly finds as a percentage of the total number of finds within each band...

Finds per month, north of N60:

 

ECseasonalN60-N90.jpg

This is as you predicted - it shows a very strong summer bias.

 

Finds per month, between N30 and N60:

 

ECseasonalN30-N60.jpg

Nothing unexpected - it still shows a summer bias.

 

Finds per month, between the equator and N30:

 

ECseasonalN0-N30-1.jpg

This one really surprised me - it appears to show a (slight) winter bias? :huh:

Any theories why this would be?

 

Finds per month, between the equator and S30:

 

ECseasonalS0-S30.jpg

Not much to see here - maybe a slight spring bias?

 

Finds per month, south of S30:

 

ECseasonalS30-S90.jpg

(I had to combine the S30 - S60 with the more southern finds; there was not enough data for a separate graph.)

As expected, again a fairly strong (southern) summer bias.

Nice work!

 

I expect the reason the "summer bias" doesn't show through so much on the southern 30-90 earthcaches is simply a matter of volume - look back at your graph of the latitude of EC finds and the Northern hemisphere has orders of magnitude more finds so it stands to reason you'd get a smoother graph there. Down here in the southern hemisphere, the true trend hasn't risen out of the noise yet. Also, speaking for New Zealand, for example, we get a LOT of tourists, particularly from Europe, coming here at all times of the year - I know because I get EC answers coming through from them constantly.

I agree with you, but I think this deserves its own topic to discuss, as it's really off topic from this discussion of earthcache statistics.

I don't understand your hostility (all caps). This is on the topic of earthcache statistics. Please avoid derailing the current discussion.

The difference of 1.8% is almost certainly insignificant, and I think it is safe to say that the changeover made no difference to the popularity of EarthCaches.

You're probably right, that the 1.8% is insignificant, but it would be very interesting (but next to impossible) to compare the average visits of pre-changeover EC's that would be approved under the new rules, pre-changeover EC's that would not be approved under the new rules, and post-changeover EC's (that for the most part comply with the new rules).... I know, impossible as it would require checking and classifying every old EC, but my hypothesis would be that many of the old-but-now-non-compliant EC's would have easier and less complicated tasks, and may show a statistically significant difference.

 

IMO this is not the correct metric - I dont believe it is the number of visits - as a finder will be unlikely to look at the date of publication - it is probably related to the average hiding ratio (EC's to total caches) pre-guideline change and post- guideline change. Even FP are too erratic and a poor indicator based on touristic location etc.

Could you truncate the Northern hemisphere data - or publish a Southern Hemisphere only graph please. I'd like to see the distribution in those other latitudes too please.

No, I should explain myself better. My hypothesis is that visits to post rule change EC's might be down because the rule changes have made the earthcaches more difficult. Unfortunately the waters are somewhat muddied because many post rule change EC's should not have been published under the new rules (I could cite many examples, but I won't, because that's not the point of this discussion!) and also quite a few pre rule change EC's were already up to the high standard of the new rules. I may very well be wrong, but common sense tells me that if someone opens an EC page and sees some lame question about reading a number off a sign, vs another EC that requires them to identify some crystal vein vs some other feature, measure it's angle and explain how it formed, you know which one they will prefer for the quick smiley right?

 

I refer you back to a comment I made earlier about popular earthcaches not being the best earthcaches. I have personal experience of this too as I own an earthcache at a spot where the was a previous earthcache that the owner threw out their toys and archived one day. Their earthcache had zero geological learning but was very popular because it's an amazing spot. My earthcache is at the same spot but focusses on some actual geology. It gets good logs but I feel not quite as many or as good logs as the previous one did. I don't particularly care and I'm happy mine is of a higher quality, but still, that's my hypothesis played out on a very micro level.

Have you looked at whether these newer, "harder" caches are being visited as often as some of the older ones where the requirement to log might be "Read the sign and tell me how high this pretty waterfall is"? This might tell us if cachers are still as interested in finding ECs.

To compare apples with apples, I compared the last 500 ECs published (worldwide) before the changeover to the more stringent guidlines, with the first 500 published after the changeover on January 1, 2011. And, to eliminate the novelty factor, I only considered finds since January 1, 2012, i.e., a year later:

 

The average number of finds for the pre-changeover ECs: 79.5 finds since January 1, 2012

The average number of finds for the post-changeover ECs: 78.1 finds since January 1, 2012

 

The difference of 1.8% is almost certainly insignificant, and I think it is safe to say that the changeover made no difference to the popularity of EarthCaches.

After thinking about your results some more, I started to wonder if there is another way to look at these data. The average number of finds is similar, but is the distribution of the number of finds also similar? A large number of new and frequently visited ECs could artificially raise the average, even if there were more ECs at the less-visited end of the curve due to the new rules. Can you do histograms for these two data sets?

I think we agree on the whole here.

Especially about the favorite points being poor indicators of "good" earthcaches alone. Although some of these really are great ECs. But just because you have an EC next to the statue of Libery or Eiffel Tower and get a gazillion hits every year - does not make it a good EC.

 

Perhaps your hypothesis about cachers not going for the more difficult ECs holds true in your neck of the woods - but here in Africa where ECs are fairly sparse - I would hazard that finders will go for them irrespective - probably based more on D/T rating than if a lame task or more educational one is expected. Perhaps this is just an anomaly here?

Yes, I've experienced your neck of the woods :) I expect the sparsity of earthcaches there does change things. In fact, even in NZ I don't think the effect I hypothesised would be noticeable. I just figured it might appear where there are a lot of earthcaches and finders can be more selective for the quick smileys...

Number of EarthCaches published per year:

 

ECsperyear.jpg

 

I find it interesting that the number of new ECs have been steadily decreasing since 2010. Why would that be? It is definitely not following the trend of the other cache types. Are we reaching saturation in Europe and the U.S.A., or is it more difficult to get a new EC published now?

I believe both are factors...not to mention certain very common types (historically) of earthcaches are not approved (artesian wells, erratics to name just a few).

 

I am fine with the lower number personally.

Frequency distribution of active period:

 

41.7% of the 357833 EC finders (until the end of March) have found only one EC. The following graph shows the distribution of the career lengths of the rest, in 6 month intervals:

Monthly archive probability:

 

ECmonthlyarchiveprobability.jpg

This graph may need some explaining: It does not directly show EC survival probability; I'll get to that later.

What it does show is the probability that an EC will be (more correctly: was) archived during any given month interval.

To give an example: The probability that an EC will be archived during its second month after publication is about 0.21% (the second bar on the graph).

 

It is not really surprising that there is no obvious pattern here, because the mechanisms causing EC archiving is very different from normal caches.

See for example the following graph for traditional (South African) caches:

For traditional caches there is an obvious high infant mortality, probably because of muggling and access problems, which is absent for ECs.

Cumulative archive probability:

Once again, this is not really related to EC survival probability, since here I only looked at ECs that had been archived.

What it shows is that the initial (first 5 months) rate appears to be slightly higher than the rest, and that 50% of all the archived ECs had been archived before 27 months after publication.

Average number of finds per Difficulty or Terrain:

Nothing unexpected here - as the Difficulty (or Terrain) goes up, the number of finds come down.

 

Total number of ECs per Difficulty or Terrain:

EarthCache finds over time:

Yearly finds, worldwide:

 

ECfindsyearly.jpg

The total number of finds per year seems to have stabilised - since August 2012 the variation has been less than 5%.

Monthly finds, worldwide:

Seasonal finds, worldwide:

 

ECfindsseasonal.jpg

I was really surprised to see the huge variation through the year - August has more than 3 times the finds of January!

 

Well, vacation period .. these figures mirror my own experience. I find EC in January or November only occassionally. But when it comes to July, August, September, I go out hiking around Europe for 2-3 weeks and come home with good backlog of EC to respond [:)]

No surprise. Many tourists are visiting a lot of natural landmarks especially during 'season' - whether it means May-Oct or only July-August.

Farthest Earthcaches:

The following two ECs are separated by 20012.22km:

GC3QF05 – Fish and Shapes (in Portugal)

GC2BXFZ – Mangarakau Swamp (Earthcache) (in New Zealand)

These two caches are literally on opposite sides of the earth, less than 3km from the theoretical maximum, according to the earth model I’m using.

 

Closest Earthcaches:

The following two ECs are only 10m from each other:

GC1BH9B - Artesian Brother

GC1HW01 - Two Artesian Erratics (both in Indiana, U.S.A.)

Cool fact! I have found the two in Indiana!

Are you able to do an EC D/T grid for just the United States?
