What is BioBase All About?

We’ve made historical bathymetry and aquatic habitat mapping quick and cost effective!

 BioBase has three main concepts: (1) Data Collection (2) Automated Data Processing and (3) Interactive Display. Acoustic data our subscribers collect using Lowrance HDS depth finders is automatically processed and warehoused online in a private account.

Our algorithms process for depths (bathymetry) and plant canopy height (sav abundance). By collecting data each time you or one of your colleagues are on the water, you are able to develop a historical database of aquatic habitats.

This powerful System uses the raw acoustic data you collect and sophisticated cloud based algorithm processing and GIS tools. Data collected on SD cards while on the water is uploaded to an online account where it is processed by our servers automatically. This innovative mapping solution has instantly made historical SAV and lake ecological habitat studies cost effective by reducing the technical skills, staff, and hours to produce vegetation abundance maps from raw sonar collection. The result a comprehensive and historical look at lake status and SAV changes over time in relation to important characteristics such as invasive species, herbicide performance, abundance, and resilience.

These historical maps can be used to monitor management successes, allocate efficient management, and provide detailed displays when reporting results.

One of the major benefits of cloud based software is that as we make changes to our algorithm or push out new features, everything is automatically associated to every trip you’ve uploaded to the System. For example: We recently pushed out a total water volume analysis tool in our standard reporting. Every trip uploaded to the System before this feature was available now has total water volume details.

CI BioBase also provides an objective output that is consistent from trip to trip. This provides objective uniform reporting for every trip uploaded to the System. We’ve removed the human element from the processing! Our servers don’t take breaks or vacations!

Since you no longer have to do the processing, the door is open to gathering data each time you’re on the water regardless of whether you’re actively managing a particular water body. The best time to plant a tree was 20 years ago; the second best time is now. Start building a historical database of the lakes you manage today with BioBase! Don’t wait until you have a project on a particular lake to gather historical data. Now anyone can map depths and vegetation every time they’re on the water!

Water Volume Analysis

BioBase is powerful! The centralized (online) nature of our System allows us to offer new features to our customers and make them available to trips that have already been uploaded to the System. A perfect example is our recently pushed out water volume analysis feature that is included in the standard report generated from every trip.

We employ a TIN (triangulated irregular network) to provide total water volume of a water body in cubic meters. A TIN is a vector representation of a lake bottom produced with irregularly distributed lines and nodes with 3D coordinates arranged in a network of nonoverlapping triangles. Since the BioBase System already uses an X, Y, and Z coordinate system for bathymetry, we can use a TIN for water volume analysis. An advantage of using a TIN is that the points of a TIN are distributed variably using an algorithm to determine which points are most necessary for an accurate representation of the lake bottom.
Actual covered water volume is based on the surveyed area only. In addition to actual, we also offer the total water body water volume that is based on a universal kriging algorithm that estimates contours (using statistical analysis of actual data) to the shapefie boundary. TIN analysis will be more accurate with more data points gathered with you Lowrance HDS depth finder. However, we have found that there are diminishing returns when adding more data points to improving the accuracy of the water volume analysis. Here are a couple trips on a 3.2 acre lake for comparison:

Less data collected (1019 data points):
More coverage (1546 data points):
Both trips merged together:

“Actual” represents the total surface area of the water body sampled with your HDS sonar unit. Although we also show acres covered, “Total” represents total acreage of the shapefile. Total Lake Volume represents total volume using the TIN analysis with kriged estimates using the actual data points. More data points means more accurate contours and more accurate volume. More variability in the contours could mean more places for water to fit in the pond. All relative to the water body size, when data points increased from 1019 to 1546 and actual coverage increases from 59% to 90%, total volume increased by ~6k cu. m. However, when merged together (using our trip merge function) and data points increase from 1546 to over 2500, total water volume only increases by ~300 cu. m.

One way to potentially add more actual coverage to this trip would be to cross some of these with vertical zig zags. We provide the tools and allow you to decide how to maximize them.

Bathymetric and vegetation mapping is easy with the automated CI BioBase System. We’re changing perspectives on what it mean to map and who can do it.
