I’ve used little scraps of time during the hurricane to experiment with the Google Maps API.
I hope to simplify it so that people can set up a map in the OPML Editor outliner, by entering a list of names of places and have them appear as icons on the map. They also get to specify the icons, from the set of Glyphicons. And of course they can write a document for each, in the outliner. The outlines will be displayed more or less the same way as the About outline on Scripting News home page.
I’d rather not read a whole O’Reilly book on this API. I’d like to find a narrative to explain these topics:
- 1. How to turn a name of a place into a lat-lng value. I see there’s an entrypoint for this, geocoder.getLatLng.
- 2. How to get a callback when the user clicks on an icon. It would also be nice to know where the mouse-click happened, on the screen, so the window can pop up close to it (I have no idea how to do this, but will have to figure it out).
I see this as another way to do a presentation, or to organize information. I would like to have a single outline for a map, making it super-easy to edit, and also to have it in the most convenient form for someone browsing over the data.
Any pointers are much appreciated.
- Thanks to some pointers from Ted (see below), my test map now have markers that:
- 1. Are specified not by latitude and longitude, rather by human-understandable strings like Roosevelt Island, New York, NY and 23rd St and Park Ave, New York, NY.
- 2. When roll over the icon you see the human-understandable string.
- 3. When you click on the icon and alert dialog pops up with the string.
- This is important because the string is what’s going to be in the main headline for each chunk of outline text. In a sense it’s the address both in physical space and in the outline. Being able to go from a mouse-click to that string is an essential step.
