MassGIS is pleased to release the latest version of OLIVER and MORIS (the "ocean" OLIVER).

Developed by MassGIS, CZM and SeaPlan (formerly Massachusetts Ocean Partnership), version 2.0 of OLIVER includes many enhancements and bug fixes:

  • More basemaps including Bing, OpenStreetMap, CloudMade and TopOSM
  • Better printing
  • Now 3 ways to extract data (by bounding box, by drawn shape or by selected feature shape)
  • Ability to change the color of points, lines and polygons (within a limited palette)
  • Permalink URLs (to send or bookmark) that support color changes and opacity - so that the link you send exactly represents your map!
  • Ability to add selected external (from non-MassGIS servers) WMS layers
  • Streamlined data extract process
  • Bigger, more visible buttons and banner
  • Dropdown to zoom directly to town (OLIVER only)

In addition to the above standard features, OLIVER is now more configurable to create custom viewers.
Along with adding custom datasets, titles, logos, default layers and geographic extent there is now also:

  • Capability to Draw and edit to live database layers (including optional snapping and splitting)
  • Configurability for many buttons and tools to be hidden if not needed
  • Dropdown options to zoom to extents; optionally narrow down dropdown choices within geographies

For state agencies MassGIS can design and host custom "OLIVER"s. For information, contact
For more information on configuration options see OLIVER developers documentation and configuration examples.
The OLIVER toolkit is an open source project that can be found on Google code as the "morisoliver" project.
