2 unterschiedliche Ergebnisse zur Multi-Matrix

Wed, 14 Jan 2026 13:05:33 +0000

Hallo,

ich habe 2 unterschiedliche Angaben zum Stand meiner Multi-Matrix.

Laut Checker fehlen mir noch 2 Wertungen. Nach dem DT-Matrix-Tool angeblich 3. Interessant ist auch das die Zeilen- und Spaltensummen unterschiedlich sind. Ich meine mich zu erinnern, das im D/T-Matrix-Tool schon mal 2 fehlende Wertungen gestanden hatten...

Viele Grüße Alex

Missing cache lookup for D/T only works for the next matrix. Can they be added for other matrices (optional)?

Sat, 18 Oct 2025 13:07:25 +0000

I can´t no longer find the filter for loops on the map for DT-matrix.

Thu, 14 Aug 2025 10:45:08 +0000

I can´t no longer find the filter for loops on the map for DT-matrix. Why os it gone?

Some time ago it was possible to do specific searches to fill the 81 matrix of different kinds only

Thu, 14 Aug 2025 09:43:29 +0000

Some time ago it was possible to search for D/T combinations to fill e.g. the matrix for one type of caches (e.g. Multi-Matrix). If I search for missing D/T combinations now and set a filter to "Multi Cache", it shows only caches which fills the next loop of the total matrix.

I would like to search for caches which fill my 81 Multi- or Letterbox- matrix specifically. The search tool only provides caches which will fill the total matrix to the next loop.

81-Matrix nach Typ/Größe filtern

Mon, 04 Nov 2024 07:37:02 +0000

Hallo,

in der Statistik kann man ja die 81-Matrix nach Typ/Größe filtern. Das System lässt es jedoch nicht zu das ich Typ und Größe kombinieren kann. Es kann nur nach Typ oder nach Größe gefiltert werden.

War das nicht mal anders? Ist das so gewollt?

On the D/T chart was a cache type selector. Why it is now missing?

Sat, 21 Sep 2024 12:18:44 +0000

From time to time I was happy to use the selector to see the D/T matrix per particular type. Now the button is missing there. Not sure if this is intention or a bug, as there is note on the membership page that the open functionality will not be reduced ("There are no plans to remove any content that are currently available to everyone and make it available to paying members only").

How do I set the filter of the D/T 81 Marix in order to have an earth cache in every field of the matrix?

Fri, 17 May 2024 09:31:36 +0000

I would like to fill my 81 matrix with only earth caches. Just as this is also displayed in the profile statistics. Unfortunately I can't make the settings on the https://project-gc.com/Tools/MapMatrix page. I only ever see the cache for the next round that is still open.

Difficulty / Terrain chart is only for all caches (not for multi, EC, wherigo etc.)

Thu, 02 May 2024 10:54:48 +0000

The "difficulty / terrain table" (in profile stats) is for all caches only (not tradi, mystery, multi, EC, wherigo, etc.). They were there before the last modifications.

Thank you for the explanation.

D/T Grid per country

Sat, 02 Sep 2023 17:13:43 +0000

Is there a tool anywhere that allows you to look at your D/T grid per country?

There is a challenge that requires a full grid in two countries, but I have achieved that, so it just reports on the two completed countries

I want to check my grid for countries I haven't completed.

Project GC awards an 81 add-on on the country badges, so it must be able to process the data, I just can't find the way to run it for myself (and for incomplete countries).

Thanks

Is there any Checker for Attributes per 365?

Wed, 02 Aug 2023 10:49:30 +0000

I know this checker (Project-GC - Challenge checkers) for attributes per 81-D/T-Matrix and I wonder if it is possible to run it for the calender matrix as well??
Like this one for different cachetypes?

So, having a checker to look for each individual attribut per each calender day would be helpful.

Thanks

D/T rating on cache markers on map

Mon, 31 Jul 2023 07:48:09 +0000

c:geo has a very nice feature where it can show D/T rating indicator on caches on the map. This makes it easy to get an overview of caches in an area without having to individually view them.

I'd like to see a similar feature in PGCs maps where an (optional?) D/T marking is applied to icons on the map.

Gibt es eine 365-Statistik nach Cachetypen?

Fri, 16 Dec 2022 14:48:29 +0000

Hallo,

ich habe schon 81-Matrixen nach Cachetypen gefunden und gesehen.
Aber gibt es solche Übersichten, nach Cachetypen, auch für die 365-Matrix?

Muss jetzt keiner das "Rad" neu erfinden und die Webseite dafür um zu programmieren. Entsprechende Checker würden mir ja auch genügen.

Gruß Alex

Add filter "Cache type" for "Top DT Loopers" statistics

Mon, 11 Jul 2022 11:59:02 +0000

Hello developers,

is it possible to add the filter "cache type" or "D/T cache/Type" to the "Number of Loops of the DT Chart"?

For example I would like to know which geocachers in my county have fullfilled the Wherigo or Letterbox DT chart.
I don't know of any other way to get such an overview

New Filter in Map D/T tool for country

Fri, 12 Nov 2021 07:46:29 +0000

I would like to have the possibility to filter my D/T matrix by country, so I can see which combinations I miss receiving the 81 AddOn on the specific country badge.

The Location filter does not help as it only limits the search for the next loop to the specific county but does not filter my already found caches

Or maybe easier: How does my matrix look like only counting caches from one specific country?

Thanks in Advance

D/T Matrix for special cache type

Mon, 23 Aug 2021 20:13:05 +0000

If I use the D/T Matrix for a special cache type, I can set the looping.
I set the loop to one and search for a type that has not been found 81 times. The result is still my complete loops.
Is that a bug or a feature?

How to check for missing D/T ratings for a certain type of cache

Fri, 16 Apr 2021 08:07:10 +0000

When using the D/T Matrix tool, I want to see which D/T ratings I need to fill my matrix with multi-caches only. No matter waht quantity I put for loops, it shows only the multi's I need to fill my complete 18th grid, not the multi's I need to fill my grid with multi's for the 1st time.

Can this be done ?

Is there a tool to see my own found caches for the D/T matrix?

Fri, 04 Dec 2020 22:15:28 +0000

I imagine this has been asked, but I have been poking around the forums trying to find an answer. If it's in here, please point me in the right direction.

Have been using the Need Found Dates tool and it is great and seeing the number of caches on the dates after filtering what I need to filter. I'd like to do the same for the D/T Matrix. I see the Map DT Matrix tool will show what I need, but I'd like to know what I have. For example, I'd like to know where I am on the D/T Matrix if I'm only filtering for EarthCaches or another cache type. IS this tool already here and I just overlooked it? Is it something being worked on, based on the beta label for the D/T History tool? It'd be a great tool to have.

D/T-Matrix für ausländische Caches

Wed, 04 Mar 2020 11:35:17 +0000

Für den Badge "The Traveling Cacher" gibt es die Addons
- "D/T - Log all (81) unique D/T combinations in at least two different countries" und
- "366 - Log geocaches on all 366 unique calendar days, in at least two different countries."

Gibt es eine Möglichkeit abzufragen welche D/T-Kombination/Log-Dates innerhalb bzw. ausserhalb des Heimatlandes fehlen?
Also eine Einschränkung des D/T-Matrix-Tools für nur inländische bzw. nur ausländische Caches?

Count d/t combinations in specific aerea

Thu, 14 Nov 2019 15:57:22 +0000

Is it possible to count (at that moment active) all caches with all d/t combinations for a specific aerea and have that shown in a matrixgrid?

Search for missing D/T matrix challenge combination

Mon, 04 Nov 2019 09:13:58 +0000

Hello, in the challenge caches section we can already see what D/T combination we have/are missing. Is it possible to implement the search for those combination missing for challenge caches?

Thank you.

D/T history, would be nice to filter somehow (current D/T) to see only what matter for lost full matrix

Sun, 16 Jun 2019 09:20:02 +0000

Nice to have this tool, but report a lot of results, would be nice to have the possibility to filter somehow to narrow the results to what matter when you loose the complete matrix or to see why something change in stat.

In fact the same demand you already have and probably work on on it : to have a homogeneous system of filter(s) on each and any statistics you propose. Thanks in advance

Search with D/T-Matrix tool to fill specific (single) "cache type matrix"

Sun, 23 Dec 2018 19:51:58 +0000

The basic configuration of the D/T-Matrix provide only to fill the "total" D/T matrix and show list of potential caches. An extension is to filter the output by cache type or even by size.

Like to have as input the matrix filtered by cache type and get as output list of potential caches of the filtered cache type.

e.g. goal is to complete (next round) of the D/T matrix for Tradi, as like can be filtered within the Profile.
make D/T-Matrix tool only to provide Tradi to complete the D/T-Tradi-Matrix.

sure also for other types ... like Multi, WIG, Letterbox, Earthcache, ...

Incorrect DT Matrix

Sun, 09 Oct 2016 16:16:41 +0000

There is one cache missing from our DT matrix.

We have had only 1 D1T5 cache for a long time - GC54N9C. Then on 5 Oct we logged a second one GC5HNAZ Our DT matrix did not update for this one so I went into Self Support/Refresh and refreshed the cache. The next day, no change so I refreshed it again yesterday and then waited until today for the stats to update. Still no change and we still show 1 find in the D1T5 block.

Project GC has recognised out find as it does not show the cache as a suggection to fill the loop.

Split up D/T field in Map DT matrix checker

Sat, 12 Mar 2016 14:28:50 +0000

Related to this question, the /Maps/MapMatrix result still has a combined D/T column, making it impossible to sort by Terrain first, then Difficulty.

Can this please be solved in a short timeframe, if the move to another table renderer is a long-term plan?

Changed D/T rating for cache - how to find the cache this was done for?

Sat, 17 Oct 2015 17:16:15 +0000

Is there a way to find which of the caches that I've found have had their D/T rating changed since I found them?

The reason for my question is that up until recently I had a full matrix. Now the owner of a cache that I had found has changed their D/T rating for the cache from 4.5/3 to something else. This left me with a hole in the matrix. I know that can easily be fixed by finding another cache with that rating, but that's beside my point. I'm just curious to find out which cache has changed their rating, and can't easily trace back which one that was. Especially as that cache has now obviously gone from the "Way to 81" list too, and I see no way to look up old "Way to 81" lists. Any suggestions are welcome.

Missing entry in D/T matrix

Wed, 26 Aug 2015 08:04:49 +0000

According to my geocaching.com statistics I have 4 blanks in my D/T matrix, according to project-gc.com there are 5 blanks, it shows an additional blank for D5/T3,5. I have checked the My-finds-query and there is a cache with D5/T3,5 (GC4DKBN, found on 2014-05-13). How come this one isn't displayed on project-gc? It also doesn't appear in the "way to the 81 matrix"... But the number of founds is right...

Why the D/T Matrix tool suggest me to look for a cache that has been archived for over two months?

Sat, 22 Aug 2015 04:08:10 +0000

I search for caches in Mexico, today August 28, 2015, to fill the missing cells of my D/T matrix using the D/T Matrix tool and one of the caches it suggest me was archived on June 8, 2015, over two months ago. Is ther a bug to be fixed on the Tool?

The cache in question is GC1HJ0A Mostly Ghostly!! Night Cache.

Request: Cache type filter in Top DT loopers

Mon, 09 Mar 2015 13:45:04 +0000

Would be nice to see who's topping the lists for multis, unknowns etc. As I see it there is no other way to do this than to check known nicks in the Map Matrix tool.

Cheers,

I need specify in form - that i need now to see the caches (from Czech Republic) for the second iteration.

How i can it deal?

thank you very much

Flexible query for 81 matrix?

Fri, 30 Jan 2015 21:27:54 +0000

Is it possible to carry out a query for flexible D/T combinations, with additional filters for country/region and/or cache type?

Maybe a 81 matrix where each cell is selectable?

Examples: A query for D/T 1/1, 2/2, 3/3, 4/4 and 5/5 for traditional Caches in Germany.

Or D/T 2,5-5/5, 3,5/4,5 and 5/1 any cache type for Netherlands to fill the international 81-matrix.

Feature Request: Needed Found Dates colour map

Sun, 25 Jan 2015 10:52:35 +0000

This is an idea for a possible improvement to the 'Needed Found Dates' page of the site.

I only have one date on which I haven't found a cache, that being the 29th February because there hasn't been a 29th February since I started caching and I have to wait until 2016 for the next one. I do, however, have approximately 60 days where I have only found one cache. I was wondering whether it would be possible to have a grid similar to the one displayed on the 'Map DT Matrix' which shows not only the days where you haven't yet found a cache, but also the days missing in the next 'loop'. For example, days with no caches could be coloured red, days with the next lowest count (in my case 1 cache) could be coloured yellow and all other days could be coloured green.

This would give cachers the challenge of finding caches on certain dates to complete their next calendar loop and lead to another statistic of the cacher with the highest number of caches on 366 days of the year.

Matrix problems

Wed, 31 Dec 2014 16:10:12 +0000

Hi togehter,

in my D/T- Matrix i think there´s a mistake between project-GC an Geocaching.com.

I missing the 5/2.5 Cache in project-GC. I found the cache. It´s: GC4XVHG

I don´t know why this is not shown at project-GC

Thanks in advance for your help.

Feature request: Link to found caches in D/T matrix

Mon, 17 Nov 2014 12:29:12 +0000

It would be a very nice feaure if the founds in the D/T matrix would be a link to the actual founds.

For example if I have found 11 caches with 4/5 and I click on the number "11", all my 11 founds with 4/5 will appear in a list.

I really like the excisting feature that You can choose cache type in the D/T matrix from "All" to "trad", "unknown" and "multi". Above request would make the matrix grid handy and prefect!

Req: Overview sum of caches for each type for each D/T for a selected Country

Mon, 17 Nov 2014 06:48:38 +0000

Is it possible to show a D/T-matrix of the sum of all caches in a selected Country, optionally selecting cache type? This way it is possible to see which combinations are rare. This filter might help that cachers create more caches with rare D/T combinations.

Need a checker for GC49P0E (mysterys in a row) :)

Thu, 06 Nov 2014 14:22:37 +0000

Diese Challenge darf von jedem Mystery-Fan geloggt werden, der bis zu seinem Logdatum neun passende Mysteries gesammelt hat. Diese neun Mysteries müssen eine komplette Zeile oder Spalte in der Matrix füllen und in der Summe ihrer D/T Werte mindestens 54 betragen. Das entspricht mindestens D3 oder T3. Viel Spaß mit dieser Challenge!

Spätere Änderung: Wer also die Reihe nicht komplett hat, darf ab sofort auch loggen, wenn er über die Gesamtpunktzahl der D- und T-Wertung von mind. 54 kommt. Weiterhin gilt: keine D- oder T-Wertung darf doppelt vorkommen.

Verstehe ich jetzt so: Finde aus jeder Zeile der D-Wertungen ein Fragezeichen, wobei die Summe aller Ds und Ts über 54 liegen muss.

short version in English: Find 9 mysterys with different D-values. The sum of all Ds and Ts must be equal to or higher than 54.
