Following Transects while BioBase Mapping
A frequently asked question of BioBase users is how do you ensure proper coverage of a water body you want to map? Some years ago we published a blog on the topic of aquatic mapping strategies and transect design that is still very relevant today. Here we focus our attention on some practical tips and tricks that takes theory into practice and gives you guides or lines to follow on your Lowrance Chart. Note that we won’t walk you through every screenshot or setting, but rather point you to the key tools and features that will get you started. We do publish more in depth tutorials on biobasemaps.com/supportresources. This isn’t an exhaustive list, so please share additional tips and tricks in the comments!

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.
