Carolina Bay Survey Maps
The Map show below is interactively driven by a Google Fusion table. The green rectangles identify regions to be surveyed, and link to 1/3 arc-second DEM imagery available at the 100K Quad level. Clicking on one of these placemarks will bring up a bubble with links to return the KML metadata file to your computer for viewing USGS 1/3 arc second DEM hsv-shaded maps within Google Earth.
The next Google Fusion map here identifies 1/4 degree "octants" (yellow & green placemarks) being surveyed for possible Carolina Bay landforms. Due to the numerical count of these landforms in our survey (currently >22,000), we are looking for collaborators who would be kind enough to annotate our Google Fusion Table structure with their observation of bay locations.
The Map next is also interactively driven by a Google Fusion table, and shows the progress of the survey. Yellow placemarks identify octants to be surveyed, and indicate that only 1/3 arc-second DEM imagery is available, while the green placemarks signify that LiDAR-quality DEM imagery has been created for that 0.25degree x 0.25 degree octant. Clicking on one for any of these placemarks will supply the user with the KML file for use in the Google Earth Application.
The next interctive plug-in map is a hybrid, showing all 23,000 + bays surveyed to date (the small round placemark dots) along with the extend of Octants which have attached high resolution LiDAR overlay sets - the larger green placemark icon. Clicking on either of those placemarks will bring up a popup with a link to the relevant KMZ file for downloading into the Google Earth appliction.
Each Octant will eventually be composed as shown in the Plug in window below. Note that the plug-in window here does not fuction like the full Google Earth application would, as you can not load the bay planform overlays from the pop-up links into this window. Instead, the KMZ file will be downloaded to your system for use directly in Google Earth.
These maps are created using a process discussed in our USGS National Map Mashathon entry. A detailed slide show of the process is available as a slide show HERE on our cintos.org site, or can be downloaded as an 18 MB PDF flie.
