The Map URL API

URLs have the following structure. Note that in all cases where a query string follows a directory the separating '/' is optional (i.e. http://map.cam.ac.uk/x/?q=s is exactly the same as http://map.cam.ac.uk/x?q=s).

URL	Description	Examples
http://map.cam.ac.uk/	displays the home page of the University map	http://map.cam.ac.uk/
http://map.cam.ac.uk/name	displays the map homed in on the item called name. name is URL encoded text for any entity the map can locate, ignoring case and punctuation and including any synonymous forms (such as Road vs. Rd). In fact this is simply an neater abbreviation for 'http://map.cam.ac.uk/?q=name' (see below). If you want to link to a map on the centrally hosted site, this is the best kind of URL to use. But consider embedding a map: see below. Older names will still respond to searches providing a cross reference is included in the database (as it was in the older system), or the old name is present in the 'AKA' field.	http://map.cam.ac.uk/Lucy+Cavendish+College http://map.cam.ac.uk/austin%20building http://map.cam.ac.uk/Fenner%27s http://map.cam.ac.uk/Tennis+Court+Road http://map.cam.ac.uk/fitzwilliam+st http://map.cam.ac.uk/queens+college (note the absence of apostrophe).
http://map.cam.ac.uk/?ref=ref	displays the map homed in on the item(s) referenced ref. References are geographical information and refer to entrances, buildings and sites/colleges as indicated by the ref=... tag on the corresponding OpenStreetMap data. ref can also be a list of references separated by '|' (up to 25 can be requested at once). Where buildings or sites are selected the corresponding main entrances are also displayed.	http://map.cam.ac.uk/?ref=STEDMUNDS019 (which is the Library building in St Edmund's College) http://map.cam.ac.uk/?ref=WOLFSON--W (Wolfson College W staircase)
http://map.cam.ac.uk/?inst=inst	displays the map homed in on institution(s) identified by inst, the institution code, which is case insensitive, or a list of these separated by '|' (up to 25 can be requested at once).	http://map.cam.ac.uk/?inst=CS (computing service) http://map.cam.ac.uk/?inst=cs (ditto) http://map.cam.ac.uk/?inst=lcc (Lucy Cavendish College) http://map.cam.ac.uk/?inst=lucy-cav%7Cjoh (lucy Cavendish and St John's Colleges)
http://map.cam.ac.uk/?q=search [&one=list] [&partial=yes] [&filter=filter]	displays the map page with results of the search for the URL encoded string search. Multiple search strings may be given separated by '|' 'one=list' is optional and if given overrides the default behaviour (which is to display the single result) and instead to display it as a list of results comrpsing only a single entry. If 'partial=yes' (or in fact, 'partial=anything else') is given results returned by the search are interpreted as a partial search, that is in the same way as typing the first few letters of a word (the last word if more than one). If not present then a match is made only on whole words (including synonymous forms and ignoring case and punctuation, but in any order). Note that as a special case for non-partial searches, if a match is found on a phrase which also has a longer phrase in which the same words appear, only the single shorter result is supplied. For example 'Austin+Building' does not return 'Austin Robinson Building'. If filter is given, only results which match the filter are returned. filter is one or more of the following, separated by vertical bar, for example "filter=college|academic": college, academic, site, nonacademic, lecture, techno, street, nonuniversity. Note that if the search yields only one result and the optional parameters are omitted, then the result is identical to the URL http://map.cam.ac.uk/name as above.	http://map.cam.ac.uk/?q=Lucy+Cavendish+College http://map.cam.ac.uk/?q=lucy%7Cqueens http://map.cam.ac.uk/?q=Wolfson+College&one=list http://map.cam.ac.uk/?q=Do&partial=yes (which might yield results for Downing College, Downing Street, Downing Place, Downing Site and Doubletree by Hilton). http://map.cam.ac.uk/?q=Do (produces no results) http://map.cam.ac.uk/?q=sussex&filter=college
http://map.cam.ac.uk/?bb=lat0,lon0,lat1,lon1 [&one=list] [&filter=filter]	search by bounding box (specified as a pair of latitude/longitude co-ordinates) rather than text string. Note: no spaces after commas. Large bounding boxes can produce very large amounts of data, so please keep areas small (say < 500m). filter as above	http://map.cam.ac.uk/?bb=52.2021,0.1184,52.2047,0.1218

You can also append a fragment part to any of the URLs, that is a hash followed by further information. The fragment part comprises either one to five numbers, or another URL. The numbers control where the map is displayed initially (and overrides any default arising from the specified search). A URL provides an overlay, created manually, using UCamGeoJSON or interactively using 'Annotate the map'.

The numeric appendices are as follows (and can be determined simply by moving the map to where you want it, adding a marker if required, using a click on the map, and saving the URL from the browser's address bar).

 
 http://map.cam.ac.uk/#z
 http://map.cam.ac.uk/#lat,lon
 http://map.cam.ac.uk/#lat,lon,z
 http://map.cam.ac.uk/#lat,lon,mlat,mlon
 http://map.cam.ac.uk/#lat,lon,z,mlat,mlon

where z is the initial zoom level (from 13, furthest zoomed out to 19, furthest zoomed in), lat and lon are the latitude and longitude where the map view is centred, and mlat and mlon are the latitude and longitude where a marker should be displayed.
