Additional tools and behaviors for OpenLayers.

branch: master
README.md

openlayers_plus is a collection of behaviors that work with the Drupal OpenLayers module, version 2 and up. This module requires the OpenLayers module, but not vice versa.

This provides the following functionality:

  • BlockSwitcher: a clone of LayerSwitcher, with better themability and positioning via the Drupal block system.
  • BlockToggle: a version of BlockSwitcher that toggles between two different layers only. Useful for situations in which layers represent the same data in slightly different ways.
  • Legend: a block in a corner of a map that provides information on layers.
  • Permalink: a version of Permalink optimized to persist layers between pages with different layer setups and without explicitly using the control.
  • Popup: an interaction with point-based, clustered maps that allows clicking on points that results in scanning between items.
  • Tooltip: an interaction with point-based maps that results in following links on hover.
  • Scale Points: dynamic styling, changing point radii based on a certain value

This module does not provide thorough theming or accessory images: it's the responsibility of the site builder to tune styling.

Something went wrong with that request. Please try again.
