mod_geomap

==========

Support for displaying maps and adding geographical locations to

:term:`resources ` in the admin.

Calculates quadtile codes from lat/long location stored in Zotonic

resources, and other geo-related functionality.

Uses OpenStreetMap for display of maps in the admin and on Zotonic

websites.

Configuration

-------------

This modules has the following configuration keys:

 * `mod_geomap.provider` Either `openlayers` (default) or `googlemaps`

 * `mod_geomap.google_api_key` The API Key for Google Maps requests

 * `mod_geomap.location_lat` Default latitude for map views

 * `mod_geomap.location_lng` Default longitude for map views

 * `mod_geomap.zoomlevel` Default zoomlevel for map views (0..29)

Search query: geo_nearby

------------------------

The module exposes a new search query type called `geo_nearby`, which is used like this:

    {% with m.search[{geo_nearby id=1306 distance=10}] as results %}

Required parameters are `id` or (`lat`+`lng`), and `distance` (which

specifies the search radius in kilometers).

The results are ordered, the nearest location is given first. (When

the `id` parameter is given, the first result is thus the id itself).

Optional parameters are `cat`, which can be a list of categories to

which to restrict the resulting resources to.

Service: /api/geomap/nearby

---------------------------

Retrieve a list of resources with (basic) information about them, all

of which are in the vicinity of the given resource or lat/lng pair.

Internally uses the `geo_nearby` search mechanism, and has the same parameters.

It returns a list of JSON objects with for each resource the following

resource properties: id, title, summary, location_lat, location_lng,

location_zoom_level, created, modified, publication_start, image_url.

Service: /api/geomap/locations

------------------------------

The module exposes an API service at `/api/geomap/locations`, which

returns a list of locations for the search or id given.

Custom tag: geomap_static

-------------------------

Shows a location’s map using static images from OpenStreetMap.

    {% geomap_static latitude=52.34322 longitude=4.33423 %}

The location is taken from the tag’s `latitude` + `longitude`

parameters, or, when absent, from the `id` parameter which is supposed

to be a Zotonic resource of category `location` (e.g. having an

address).

It displays the `_geomap_static.tpl` template.

Other parameters:

`zoom`

  Zoom level (defaults to 14)

`n`

  How many rows and cols to display (defaults for the `rows` and `cols` parameters), defaults to 2.

`cols`

  How many grid columns to display

`rows`

  How many grid rows to display

`size`

  The size in pixels of each tile, defaults to 256.
