I had a brainwave this morning and was eager to test my new theory. I've been out in the field looking for caches and using gpxsonar for my gpx management and to give me offline cache details, logs and hints. I also have the spoilers downloaded onto my SD card using spoilersync however navigating to the spoilers in the list of jpg and html files is a bit of a cumbersome process (especially whilst walking on uneven ground and holding a gps in the other hand). However by creating a custom url in gsak for the spoiler location and then exporting to html the filtered caches, I now have a list of caches sorted by name,distance or whatever and when I click on the cache itself I get the details, logs, hints and a link to the spoiler html with the pictures in it.
All you need to do is include the line !spoiler=file://\sd card\my documents\spoilers\%code.html in your custom url's from the Tools menu, options, html tab. Note the ! in front of spoiler tells gsak to use this url in the export. The location of the html file can be obtained by using file explorer to browse to the file on the pocketpc and then double clicking on it. This will load the file into pocketie and you will then see the url string that you need to replace (as it might be different to my example)
Now all I need is way of logging data on each cache and I can almost do away with gpxsonar. The advantage of gpxsonar is that i can keep an entire db of uk caches on the pda in a reduced amount of disk space - html would take up a lot more and would take a long time to generate and upload onto the pda.
Copy the contents of gsakloc.txt into your locations (Tools Menu, Options, location tab) in gsak at the end of what you already have and then you will be able to select motorway junctions and service stations in filters and in arc/polygon exports. Very handy for those caching jobs at the end of a work visit :-)
Thanks to the files at Mark C's page for the initial data.
