Virtual Eyes to See Aquatic Resources in 3D

One of the biggest challenges to understanding aquatic resources are the optical properties of water and an inability of our human eyes to see the complex world that lurks beneath the surface.  In contrast, when “aeroplanes” (that’s what they were called in the Wright Brother’s days) first took flight in the early 1900’s and pilots figured out how to fix cameras to the belly to take aerial photos, it opened up a new world of exploration for biologists and foresters studying terrestrial landscapes.  The term “landscape” got a whole new meaning.

Is StructureScan worth it? You be the judge

Debating whether it’s worth the upgrade to the new HDS7 Gen2 Touch StructureScan bundle?  Outside of the bigger screen and more intuitive touch technology than its older generation HDS5 sibling, the imagery produced by StructureScan should be reason enough!
Below are the same areas of a lake in Minnesota using the traditional 200 khz signal (top) and the 455 khz DownScan add-on (bottom).  A school of fish hovering over Eurasian watermilfoil plants is clearly resolved in the bottom image.  The wider cone angle of the traditional signal cannot adequately resolve these minute features.  BioBase leverages both signals to produce accurate map data sets and reproduce spatially explicit imagery for plant cover typing.  Contact us if you would like to know more about HDS features or are interested in purchasing a unit

Lake Mapping and 800 kHz DownScan

BioBase Now Offering 800 kHz DownScan in its dynamic Trip Replay feature.

 

Trip Replay is taking a leap forward with the new option to view your data using the 800 kHz DownScan option when recording with the StructureScan™ add-on.  Anyone that has been uploading data gathered with StructureScan™, by logging all channels, can now view past and future trips with this new feature.

You may have seen our earlier posts about the BioBase Trip Relay feature.  Your raw data collection is automatically processed by our powerful cloud servers and fully mapped with kriging algorithms and other geo-statistical considerations. Once processed, you can then replay the entire trip, watch your boat travel along your transects, and ground truth the % BV heat map with the water column cross section (on the right side of the image above).   This feature allows our customers to verify every trip output for accuracy and provide objective evidence for anyone that questions your aquatic vegetation maps!

The power and accuracy of the Lowrance™ HDS StructureScan™ allows us to offer a new and amazing cross-section view (DownScan) of the water column for each trip in the Trip Replay feature.  As you can see from the images below, this feature provides amazing views of bottom and vegetation.  It is even possible to notice changes in vegetation types or habitat cover type under your boat.  With our waypoint feature, you can identify vegetation transition zones and areas of interest for typing and delineation.

 

Please let us know if you would like to add StructureScan™ to your current data collection hardware.  Although not mandatory for using BioBase, this option can be added to any HDS™ system at any time for great views underwater.  For details on using or recording StructureScan™ please request a copy of our Standard Operating Procedures.

Another great feature added to the powerful BioBase System.

ABOUT BIOBASE

BioBase was engineered to provide automated cloud based GIS, aquatic vegetation mapping and historical trend tools for aquatic habitat analysis.  BioBase leverages log file formats recorded to SD cards using today’s Lowrance™ brand depth finders and chart plotters.  Data you collect while on the water is uploaded to an online account where it is processed by our servers automatically.   We rely on automation to make vegetation mapping cost effective by reducing the technical skills, staff, and hours to produce vegetation abundance maps from raw sonar collection. With the human element gone, you get accurate and objective mapping at lightening speeds!
