Newest When 50 Shades of Grey Is Not Enough, Try 625

Q: Why is land cover change significant? A: Mapping change visualizes large-scale regional effects, either from policy and anthropogenic trends or natural environmental changes. Mapping change is harder than it sounds. First, the products for both times must be mapped with the same framework and to the same standard. Second, we differentiate areas of change from areas without change. Only the change areas are mapped, based on spectral signatures and ancillary data, without the need to map the entire area wall-to-wall for each date (this decreases consistency and accuracy due to class and



Raster Provisioning with Open Source

by Friday, November 21, 2014 @

In June of this year we had to turn off the raster provisioning software for the Digital Coast Data Access Viewer (DAV). That was the package that let us grab tiles of imagery, mosaic and reproject them, and then deliver the output to users. Unfortunately, it used Java 5 and that was considered a security hole. The company had no plans to upgrade to at least Java 7, so there was no choice but

Rain Gardens – Local Solutions

by Friday, October 31, 2014 @

I love the idea of rain gardens! Instead of expecting a government bureaucracy to spend my tax money to fix water quality problems, I can do something within my own yard that reduces the nutrients flowing into the watershed. So what is a rain garden? It's just an area that will hold the rain water for a few hours--allowing it to percolate into the ground--that is planted with pretty things that d



Don’t Stand in the Road: The Precautionary Principle and Overcoming Uncertainty

by Tuesday, October 14, 2014 @

If I were to say you had a 100 percent chance of being hit by a car if you stood in the road for 5 minutes, would you consider it? How about a 50 percent chance? A 10 percent chance? Even a 1 percent chance? What if there was some sort of incentive, like a new car? Although this scenario may seem a bit ridiculous, it is not so different from coastal management decisions. Residents place themsel



Things to Consider Before You Acquire New Imagery

by Thursday, October 9, 2014 @

Have you ever wanted to purchase new imagery (or download free imagery from a government website) of your county or municipality? Here are just a few requirements you may want to think about before writing that big check for new data. Digital orthoimagery is the foundation for most public and private Geographic Information Systems (GIS). Orthoimagery refers to aerial and satellite imagery that has



Digital Coast Lead Agency Changes Name and Gets Bigger – What’s Up?

by Wednesday, October 1, 2014 @

To maximize the nation’s coastal management efforts, NOAA has combined two of its primary coastal offices: the Coastal Services Center and the Office of Ocean and Coastal Resource Management. The basic missions remain intact, but the new structure and operational approach will increase efficiency and effectiveness. By operating more collaboratively, the new Office for Coastal Management and our

We’ve all heard stats about coastal populations increasing over time. As someone who reviews land cover imagery, I’m able to see how this plays out on the landscape. More people usually means more houses, roads, and shopping centers to accommodate the increasing numbers that either move to the coast or are born there. How are these two things related (i.e. does a certain amount of population g
