Monitoring the water quality of both inland water bodies and coastal regions is an important role undertaken by government agencies. Here in the USA, the Great Lakes are some of our most valuable freshwater sources and hence they deserve special attention. To this end, the German company, EOMAP, has developed proprietary algorithms to assess the turbidity and chlorophyll-a levels in water as well as estimate when harmful algal blooms might occur.
This algal bloom map of the Great Lakes, called eoApp US, is updated daily using a combination of (unspecified) satellite sources. Users are able to change the parameters displayed as well as change the time period covered and the statistical reporting techniques. This is a powerful application available to all users at no cost – nice work EOMAP!
Until my next edition of the Free For All, happy hunting for free geospatial goodies!
