  • Collaborative effort SeaPlan formerly MA Ocean Partnership Applied Science Associates
  • New version – still uses all of these technologies OpenLayers is a Javascript Library
  • In particular it uses WMS and WFS
  • remembers basemap, layers, styles, opacity of basemap and styles, bounding box, change of color
  • No basemap – if you want that use File/Print. But this print offers better legend, plus the ability to save the map and legend as PNG files.
  • No basemap – if you want that use File/Print. But this print offers better legend, plus the ability to save the map and legend as PNG files.
  • All the tools on the bottom can be hidden, along with the address match, dropdown, identify, external WMS, print and export
  • Dropdowns can be set up so that once you pick something such as a town, if there is a database link with another datalayer that datalayer’s dropdown can be narrowed down to only include values from the first dropdown. Here, since Malden was chosen in the first dropdown, only Malden openspace is offered (sorted alphabetically) in the second dropdown.
  • OLIVER application can be set up to do editing on points, lines or polys. The editing can be username/password protected. There is also snapping and splitting available. The attribute editing is currently basic (no ability to force users to fill out certain fields or to offer dropdowns, but we’re working on that this spring).
