    2828== Location Selector ==
    29 This section is moving to [wiki:BluePrintGISLocationSelector]
    31 There are 6 ways of adding a location, listed in ideal order:
    32  1. '''Bulk import''' has either Location Names or Lat/Lons
    33  * This could optionally use Image EXIF headers or a timesynced GPX file
    34   * NB: This refinement can be added later
    35  2. '''HTML5 !GeoLocation''': If the resource is one where the user is likely to be physically at the relevant location
    36  * e.g. pr/person/presence can be recorded automatically upon login
    37  * We should use a 'nearby' algorithm (like {{{gis.get_features_in_radius()}}}) to re-use existing locations rather than adding a new one each time.
    38  * NB: This refinement can be added later
    39  3. '''Map''': User clicks on a location on the map
    40  * If we have admin boundaries available then:
    41   * We can zoom to the correct area if a level of hierarchy has been selected
    42   * The correct hierarchy can be filled-in automatically
    43  * If not then the user can be prompted to provide these (as per 6)
    44  * Michael: It would also be useful if existing locations could be displayed on the map (prehaps with the Location Type displayed too), so that the user could add a new location relative to existing locations, or choose a existing location off the map instead.
    45  4. '''Manual Entry of Lat/Lon''': (either from a GPS or looked up in an online resource like Wikipedia)
    46  * A Conversion tool is available to convert from Deg/Min/Sec to Decimal Degrees
    47  * If we have admin boundaries available then the correct hierarchy can be filled-in automatically
    48  * If not then the user can be prompted to provide these (as per 6)
    49  5. '''Geocoder''': Street Address is entered & this is matched to a location via a [wiki:BluePrintGISGeolocator Geocoding service]
    50  * We already have functionality ready for Google & Yahoo in {{{modules/}}}.
    51  * We need to add at least [ Geonames].
    52  6. '''Hierarchical Selector''':
    53  * We have dropdowns for each of the different levels.
    54  * The country selector should remain hidden if there is only 1 country being used.
    55  * Initially just a single dropdown should be displayed.
    56  * When this dropdown is selected then the next dropdown is displayed, along with appropriate values
    57   * We download the values via AJAX in order to not have to download all Locations, however we could download the next set in the background whilst the user is thinking: means a bigger download to filter client-side, but maybe less time overall. Can be experimented with.
    58  * When the final dropdown is selected then the user has the option of adding a more specific Name & a Street Address
    59   * This should not be mandatory as some records need to link directly to the L0-L4 levels.
    61 If adding a new Location, then the name of the location should *not* be the general name, but rather a specific one
    62  * Where possible, we automate this by using the name of the Shelter or Hospital
    63   * Should we prevent 'Add Location' from working until that field is filled-in?
    64  * We need to make this clear in the online help.
    66 We want to be able to optionally specify which levels of hierarchy we are interested in for this resource. This would be part of the API for location_id()
