PNT

This is a program I am working on to replace the no longer supported Cache Register program for the Delorme Earthmate PN-40 and PN-60 GPSrs .  I am posting the current progress on this program for others to use.  Note:  This program is AS IS, use at your own risk.  It is currently unfinished, and probably contains bugs.

About PNT

    PNT stands for PN series Transfer.  It is a program designed for making transfer of pocket queries to the PN-40 and PN-60 easier.  Gpx files (the format used by pocket queries) are stored on the GPSr in a directory called "Waypoints" in either internal memory or an SD card.  The gpx file is then loaded into working memory where you can view, navigate, edit and many other things.  When you download a PQ from Geocaching.com, you can just unzip the .zip file and drag-n-drop the two gpx files to the GPSr to access them.  The problem with using drag-n-drop method, though, is that only one gpx file can be loaded into working memory at a time, and gc.com pocket queries contain two gpx files, one with the caches, and one with the child waypoints (parking, trail heads, etc...), so if you need to navigate to the parking coordinates, you need to load in the child waypoints which removes the geocaches from working memory, then when you reach the parking lot, you need to reload the geocaches back into working memory to navigate to the cache.  Switching back and forth like this can take up a lot of time, especially when you have near the maximum number of waypoints in the gpx file (1000 on PN0-40 and 1500 on PN-60).  The solution to this problem would be to somehow combine the two gpx files into one.

    Delorme had provided a solution to the problem with their Cache Register program.  It would automatically download, combine, and transfer the Pocket Queries for you.  After Groundspeak made a couple of API changes, causing issues with Cache Register, Delorme decided it was not worth fixing the program and dropped it.  That leaves you with  five options when dealing with PQs from groundspeak.  One: deal with the long load time when switching between gpx files. Two: Do without using child waypoints.  Three:  open the files in a text editor and copy the proper tags and information from one gpx file to the other.  Four and Five:  Use the bulky programs GSAK or Topo North America 10 to combine and transfer the files to the GPSr.

    None of the five options really appealed to me when I just wanted to download a PQ and head out caching.  So I decided to write my own version of Cache Register.  I could even put in improvements I had wished CR had, such as choice of which PQs to keep in sync and the ability to filter results.

PNT is not finished

    PNT is currently a workable option for transferring Pocket Queries, but is far from the program I wish it to be.  I decided to release this unfinished version for those who could make use of the currently implemented options.  I haven't finished the filtering options, and there is no functions for field notes nor accessing gc.com directly yet.  Also, there has only been testing on my own PN-60, using PQs of my own local area, so there are probably still many issues to iron out.  My plans are that once I get the core of the program worked out, I will then add gc.com access through their API which will allow automatic downloading of PQs from the server and ability to upload field notes directly.

What PNT currently has

    The program is compact, just one .exe file. You can load one or more PQs from the hard drive, either as a .gpx file or from within a .zip.  You can  filter the file based on difficulty, terrain, size, and type.  You can then save the result as one combined .gpx file to the GPSr.  It will also fix some of the problems resulting from non-standard characters which breaks the Delorme's parser causing corrupted files.
