Newest There’s a Pixel in My Pocket!

The following is a remote sensing scientist's geeky birthday tribute to Dr. Suess, who taught us all that "Today you are you! That is truer than true! There is no one alive…who is you-er than you!" Happy Birthday Dr. Suess...And happy Read Across America Day!   There's A Pixel in My Pocket! I’m a GeoZone geek And I’m happy to say “There’s a pixel in my pocket... And, I got it the Digital Coast way.”   Through Digital Coast I can travel from sea to shining sea. Downloading data and tools, that are just right for me.

The Ocean Economy: We Thought It Was Big—Turns Out, It’s Bigger

But before we get to that, here are a few random thoughts placed here to grab your attention. Let’s say a company is in the menhaden business. Menhaden are awful-tasting little fish that are harvested in large numbers and processed in factories to produce stuff that is used in other factories to make dietary supplements (fish oils rich in omega 3 fatty acids), animal feed, and a lot of other

Coastal GeoTools Reflections and Anticipation

by Tuesday, February 10, 2015 @

The Coastal GeoTools 2015 conference is coming right up (March 30 to April 2, 2015 in Charleston, SC), so I thought it might be a good time to review what I learned at the last conference and think about what interesting things this one might bring. Don't forget, the registration price goes up on March 1, 2015 and the conference tends to sell out, so don't wait too long. 5 Things I Learned at Co

Storm Surge in the Winter?

by Monday, January 26, 2015 @

We all know storm surge can be deadly and destructive during hurricanes. But, as the Northeast United States deals with yet another major storm moving up the coast, don’t forget that storm surge can be a problem at any time of the year and with any coastal storm. Storm surge can be particularly dangerous in the cold icy waters of winter. Coastal storms like this one, often called nor’easter

“Loss Is Nothing Else But Change, and Change is Nature’s Delight.” -Marcus Aurelius

When talking about land cover changes over time the terms “loss” and “change” are often used interchangeably, but they may mean quite different things. Depending on what is being mapped and the story being told, these terms need to be clarified. Change versus loss This is best highlighted by comparing maps of land cover versus land use. Land cover captures the physical state of land

Workaround for 16-bit Thematic Tiff in ArcGIS

by Monday, January 5, 2015 @

While working with our 16-bit land cover change data (see earlier GeoZone post) in Tiff format we noticed a problem using ArcGIS. The display doesn't color the image properly. The problem has been reported to Esri and they've entered it as a bug to fix in a future release. Until then, I thought I ought to give you a workaround or two. The Problem I'm going to use the C-CAP land cover change da

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
