system, or geospatial information system is any system that
captures, stores, analyzes, manages, and presents data that are
linked to location(s). In the simplest terms, GIS is the merging of

OpenLayers is:
Standards supported (WFS, WMS, GML, etc)
Integrates with free and commercial datasources
Platform independent via JavaScript
OpenLayers on Drupal
The OpenLayers Module and its submodules bring the OpenLayers
Javascript library into Drupal. They enable users to combine maps
from different map providers with data from Views and CCK
input.*

Modules Required:
Views
Chaos Tools (CTools)
Location, WKT Field, etc.

More Advanced OpenLayers Examples
OpenLayers for Drupal provides ease of use for simple mapping,
and powerful hooks for more advanced control of layers, maps, and
styles.
UI-driven OpenLayers style maps
Custom Drupal behaviors using module system
Leverage Drupal's AJAX, hooks and templates
Views relationships, arguments and filters
Summary and Q&A
"A map of the world that does not include Utopia is not worth
even glancing at, for it leaves out the one country at which
Humanity is always landing."
