Current Short List


Shortcuts for speed


Server/Connection speed


Faster map requests via Caching (TileCache)


Database optimization (indexing, normalization)


Avoid on
-
the
-
fly reprojection


Harmonize into common projection


Frameworks and Libraries for:


Security


Wrapping WMS/WFS services in authentication framework


Cross Platform Support


Get IE support enabled


UI Layout optimization


Increase map size


Online help


Increased print functionality

Current Long List


Batch uploads


Search and Query capability


Enhanced Reporting


Incorporate 3
rd

party datasets (IOOS etc), both
WMS/WFS/WCS


Custom groups for categorizing users, AOI’s, visible
datasets, etc.


Bookmarks for quickly allowing users to scale to a
project scope in the interface
