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.

Utilization of a Web-Based Mapping Interface to Enhance Inland Fisheries Management Strategies in Texas

Abstract:

Texas Parks and Wildlife Department Inland Fisheries (TPWD IF) biologists traditionally use “stand-alone” mapping interfaces to generate 2-dimensional (2-D) aerial outputs of fish habitat and benthic surveys of aquatic systems. Preliminary work has shown promise in the use of a different method, which generates interactive 3-dimensional (3-D) high-definition (HD) outputs. During field surveys, a Lowrance© Elite 9Ti GPS unit with TotalScan™ transducer was used to generate data points along boat transects on waterbodies of interest. A waterbody “Vegetation Analysis Report” and HD maps were then generated from these data using web-based mapping algorithms through BioBase©, and ArcMap 10.3© GIS software. Aquatic vegetation biovolume, bathymetric mapping, and benthic substrate composition outputs, produced by BioBase© aided biologists in selecting best management strategies, regarding aquatic vegetation management and angler access development at three central Texas impoundments. This tool can prove valuable to fisheries managers needing a higher resolution of survey results to fine-tune management strategies. At a cost of $2,5001 US for a yearlong subscription, cost-benefit would have to be assessed by individual users, based on their needs.

Training EcoSat Vegetation Classifications: User tips

What is EcoSat?
EcoSat delivers a one-of-it’s-kind semi-automated cloud processing of very high resolution satellite imagery to map nearshore vegetation and coastal benthic habitats.  EcoSat uses the latest multi-spectral imagery from reputable providers such as Digital Globe (World View 2,3 and 4), Airbus Defence and Space (Pleiades), and ESA’s Sentinel program and industry standard image processing techniques.  Sophisticated Amazon Web Service cloud infrastructure rapidly processes imagery, creates reports and imagery tiles, and delivers detailed habitat maps to user’s BioBase dashboard where it can be analyzed and shared.  Average turnaround time from imagery tasking order to delivery of results is 60 days.  The rapid and standard processing methods are allowing entities like the Florida Fish and Wildlife Conservation Commission to establish regular monitoring programs for emergent vegetation.  The extremely long and expensive one-off nature of conventional remote sensing mapping projects using non-repeatable tailored techniques has prevented natural resource entities from assessing the degree that habitats are changing as a result of environmental stressors such as invasive species invasions and climate change.
