Re: Updated Arkansas DeLorme Map Request

I would like to request a checker for my Arkansas DeLorme Map challenge (DeLorme 2.0 - GC5M640)

1. There are 111 pages total on the Arkansas DeLorme Atlas and Gazetteer map.

2. Cachers must find at least one (1) physical cache on each page to qualify. Physical caches include Traditional, Multi-Caches, Unknown, and WherIGo caches count towards the physical cache portion of this challenge. No Virtuals, EarthCaches, locationless, webcams, CITOs, or events, etc. count. In short, it must be cache that can be found and a physical log to sign.

3. The qualifying caches will not be limited to new cache hides and finds posted after the posting of this challenge. This means that any cache that was found from the time a person started geocaching can be used. There are no time/date requirements.

4. Only caches in the US state of Arkansas count for this challenge, with the exception of the special rule below:

** SPECIAL EXCEPTION TO RULE #4 **
At present, there are no Arkansas caches posted for pages 71, 106, 107 or 127. This is chiefly because the land in this area is either privately owned, or the banks of the Mississippi River change and/or flood the land mass, so that caches cannot be posted here.

However, since these 4 pages are on the Arkansas map, and their neighboring states DO have caches within these pages, the cacher must visit Tennessee and Mississippi to get at least one cache for pages 71, 106, 107, and 127 to qualify.

If it helps the volunteer, I did create my own Google Earth layer that I can send over in a KMZ file that shows all the drawn pages that I created as my attempt to use as a "checker". These pages were drawn using the Latitude/Longitude coordinates provided on the map to draw each box.

Please let me know if you have any further questions or if can be of any assistance.

If you crate the polygon a checker can be created.
Your special case with 71, 106, 107 or 127 will require you to create polygons that follow the border for the all other bordering square. To only allow different states in specified squares would require a large rewrite of the checker
There is two types of polygons that can be used rect(angles) and polypoint
Are there coroner coordinates specified on the delorme maps? And in what datum is it? For excampele USGS topo uses NAD27 and not WGS84 and has to be converted
look at http://tagis.dep.wv.gov/convert/

The fist is for all square maps pages and the later for the one that exteds into Tennessee and Mississippi where finds in those states are not allowed. Example at the end of pos and validate it as correct json at http://jsonlint.com/



https://overpass-turbo.eu/#
with the query
[out:json][timeout:25];
{{geocodeArea:Arkansas}}->.searchArea;
(
relation["admin_level"~"4"](area.searchArea);
);
out body;
out skel qt;


and export to geojson and you will get all border polygons but you have to cut out the correct for that map page
there is probity som way to do that with software help but i have never used any.
I think you can do it with http://www.qgis.org/en/site/

Thank you for your response. Will the Google Earth KMZ file I have, containing all the polygons I have already drawn out be enough to create the checker?

It has all of the pages, including the ones for Tennessee and Mississippi.

If you can provide me with an email address, I can send my KMZ file to you for review and discussion.

Razz007 - saw your post on the GC.COM forum, and replied there. If you want to send me the KML file, through my GC.COM profile, I'll take a look for you.

I've completed this checker, pending a possible polygon adjustment or two (waiting to hear back from OP/CO on that).

I had to build a distinct script for this one, as it has an unusual requirement to allow out-of-state finds for certain specified polygons.
