There are something in the region of a thousand scheduled monuments and protected historic buildings within cycling distance of where we now live. Some of them will be worth adding to OSM. I also see some of them as potential destinations or stopping points as I trundle around on the bike. I'm also trying to learn a bit about the area. So I'm interested in what is there, and where it is.
More importantly I felt like tinkering a bit with Openlayers on a smartphone.
So I've made myself a little gadget by kludging together various bits. There's a KML file of points of interest that I scraped (using Perl) from various published lists. I then edited the examples of Openlayers that use geolocation, display the OSM map, and overlay a KML file. The result is that I now have an "app" (really a web page with a slippy map) that works on a smartphone to mark Points of Interest with a pushpin. It follows me around, staying centred on my current location. A brief description of each point will pop up when a pin is touched.
For me it was a bit of a learning curve to get this working, but that says more about my limited expertise than it does about how difficult it really is. In truth none of it is very complicated.
To begin with I found it most useful at pointing out things that I hadn't noticed beforehand. Several buildings that I had been passing without a second glance turned out to be more interesting than I realised.
Now I've tried using it to locate a specific destination - and that worked fine as well. As I came home on a bitterly cold evenng it occurred to me that when our visitors arrive for Christmas and want to explore the area, we can send them out with this - while we stay warm indoors.
Pre-loading a smart phone with a collection of things that need fixing on the map seems like something that would be useful to the OSM community. An even larger group of people might like to pre-load the equivalent of a local guide-book.
But those happen to be the first two things I thought of. The nice thing is that, with the right tools in place it's fairly easy to generate data sets for displaying all sorts of different kinds of point of interest on a map.
Somebody must already have thought of this, and produced something a bit more sophisticated than my little gadget.
