New EcoSat Feature: Reclassify individual vegetation polygons

EcoSat is a first of its kind semi-automated satellite imagery processing tool that’s part of the BioBase cloud mapping platform (Figures 1 and 2).  EcoSat is helping several US states and countries map and monitor the status of shallow growing aquatic vegetation and benthic habitats.  In this blog, we discuss several tips and tricks about how practitioners can maximize the accuracy and precision of their EcoSat vegetation maps.

In this first release of EcoSat, practitioners could only change or override “global” classifications. So if EcoSat classified vegetation as “reedgrass” but you had local knowledge that the native bluejoint reedgrass grew in some areas, and invasive reed canary grass grew in others; you could not locally reclassify individual reedgrass beds into their appropriate species.

Now you can right click on any vegetation polygon object and reclassify that object (Figures 3 and 4).

Figure 3. Right click on any vegetation polygon and select “Reclassify.” Give the polygon a number and a name, save, and then reprocess the map.
Figure 4. After the EcoSat Map is finished reprocessing, you will see the new color and classification.

The reclassification action automatically adjusts the statistics and reports (Figure 5). View the automated report and send the html link to partners or clients for a rapid assessment of the cover of different species of vegetation.

BioBase is a cloud platform for the automated mapping of aquatic habitats (lakes, rivers, ponds, coasts). Standard algorithms process sonar datafiles (EcoSound) and high resolution satellite imagery (EcoSat). Depth and vegetation maps and data reports are rapidly created and stored in a private cloud account for analysis, and sharing. This blog highlights a range of internal and external research, frequently asked questions, feature descriptions and highlights, tips and tricks, and photo galleries.
