I’m currently working on a big review of GSAK for the blog. I’m pitching it as a “My thinking process” review where I reveal features as I discover them, mention features that I think are the most useful, and add some little tutorial bits for the essentials so that you don’t have to read too much documentation if you want to get started quickly and already are quite confident using computers.
Streetmap is usually my mapping site of choice, so I thought I’d work on a custom URL for it. GSAK shows British OS grid references, however they are 5 digit ones (Anyone know what use 5 digit ones are?) however streetmap and geocaching.com all use 6 digit ones therefore, trying to get GSAK to link to it was a bit of a nightmare. I eventually got there in the end using: http://streetmap.co.uk/loc/%lat,%lon but this gave me more of a street view zoom level. Passing a zoom level would only work using the grid references, which I couldn’t use due to GSAK’s being 5 digit ones…
A quick Google pulled up this post on the groundspeak forums which lead me to a 50k Streetmap. Someone else mentioned Benchmarks.org so I had a play with their mapping service and managed to generate a 25K map. This is the view I always use to bring up a public footpath view. So I can now link GSAK caches to Streetmap
Add the following lines to Tools –> Options –> HTML –> Custom URL and now when you right-click on a cache you can choose to pop-open the web browser directly to the Streetmap 25k or 50k maps.
