Through Stumbleupon, I found a list of 60 free online Computer Sciences courses one of which is Advanced Topics in GIS provided by UC Santa Barbara.

The course description is as follows:

"A series of intensive lab sessions focused on specific computational languages (e.g., Python, R, shell) and tools (e.g., GDAL/OGR, InVEST, MGET, ModelBuilder) applied to the spatial analysis of environmental problems." and reviews Python Programming, the Open-Source QGIS program, Google Earth and Leaflet.

ESRI, the GIS juggernaut, awarded Connecticut’s Changing Landscape, created by a UCONN student, first place in the Science/Technology/Education category of the Esri Storytelling with Maps Contest today. The presentation uses satellite imagery to track changes between 1985 and 2010.

Its a evocative storyline with appealing maps and charts telling the story of Connecticut's changes in land use and how it affects natural areas and resources Some interesting tidbits from the presentation:
  • Turf and grass now cover more of Connecticut than agricultural fields.
  • Between 1985 and 2010, 29,661 acres in the riparian zone were converted to developed or turf & grass.
  • In 2010, CT had 1716 watersheds with impervious cover levels indicative of poor watershed health, representing over 25% of the 6851 local basins in Connecticut.

Proposed Changes to the Wetlands Plant List

Comments on proposed changes to the US Army Corps of Engineers(USCOE) published in the Federal Register are due no later than the 13th of November.

Overall, 311 changes to the plant list have been proposed with an almost even (51% wetter /49% drier)0 split between plants receiving a wetter rating and plants receiving a drier rating. These ratings are very important as a plants presence combined with soil characteristics and water regimes paints a picture if an area is determined to be an upland or wetland.

The comment period ends on November 13, 2015 and the Federal Register is available here to read. Beyond the list is an article by the National Wetlands Newsletter on how the list and ranking system has changed and matured over the years.
