The support has a +few rough edges that still need ironing out, mostly relating to ellipsoids, +and for that reason they aren't exposed by default. + +To use Google Maps, you need to get an API key from +http://www.google.com/apis/maps/signup.html. When you've put this value into +the config file as gmaps_api_key, the maps become available to you in two +places. Firstly, if the user has set the user preference to display Google +Maps, any node which has location information will get an inset map +pinpointing the location. Secondly, the URL +http://.../wiki.cgi?action=index;format=map becomes a large map with a list +of all nodes (regardless of the user settings). The latter will become very +slow on any sizable guide (there is work being done on speeding up indexes +in general - please see the mailing list). If you don't get maps displayed +when you know that the node has location information, read on. + +Ellipsoids and map accuracy +--------------------------- + +If you are based in the US and inputting points using latitude/longitude, +the values in your database will almost certainly correspond to points on +Google Maps. If so, simply change the "ellipsoid" configuration variable +to "WGS-84" if it's not already set to this, and your maps will display. + +If you are using the British Grid system things are more complicated and this +support is incomplete. If you set the configuration variable force_wgs84 +to 1, maps will display, but points will be offset from where they should +be, normally by about 50 metres. This is because the British Grid uses a +different ellipsoid from Google Maps. We plan to integrate conversion +routines to fix this in a future release. In the meantime, if you +advertise the maps you must make users aware of this flaw and tell them +not to try and "correct" location data! + +You may be unlucky enough to be using the UTM input modes (ie not British +or Irish National Grid) but have data entered in a mixture of formats. +This is likely if your users are from the UK, as you may find a mixture of +WGS-84 and Airy (ie British Grid style) based nodes. In this case, you +*do* need to correct any that are offset. Only do this if your users +input Lat/long values rather than grid Eastings/Northings.
