Location

This module aims to implement search functionality as seen on www.openstreetmap.org. It includes:

• A search block
• A block with results of the search, for multiple geocode providers
• When search results are clicked, any Openlayers map on the page zooms to the selected location

The Drupal 7 version depends on the Geocoder module for geocoding.

The Drupal 6 version comes with 4 standard plugins:

An API module and configurable blocks to map your content to fetch enrichment from the wonderful Geonames webservice.

There are two versions of this module for Drupal 7. When Geocoder 2.x will be stable, the old Geocoder 1.x will be deprecated. The API has changed between those two modules, so please, if you use this module, get ready to update your code.

Geocoder 1.x

This module will geocode just about anything you throw at it including addresses, GPX files, geo-tagged images, and KML files.

A Drupal 7 field widget for gathering/displaying map location data, using Google Maps v3 api.

An ideal store, dealer, vendor, ATM, branch, office or member/user locator. Just about anything you can think of listing on a map.

The OpenLayers Locator is a feature module that creates a robust, turn-key Locator using the Openlayers, Openlayers Proximity, Addressfield, Geofield and Geocoder modules. Getting up and running with these modules from scratch can be challenging. This feature package simplifies that. Out of the box it provides a Location content type with an address field that is automatically geocoded using Google's Geocoder. The locations are then displayed on a combined list & dynamic map view. Users can then search for locations based on proximity to a postal/zip code, city, province, state or any other geo-spatial reference point understood by Google.

This is a data provider for IP to Locale which gets its data from any of the world's 5 Regional Internet Registries.

Next Location is meant to be a location project, a mix between Location and Media module, with GMap v3 in the first time, and after all map providers in an easy way.
