BioBase Polygon Management Tool!

Contour Innovations (CI) has just launched a new game changing feature with its polygon management tool, currently in Beta!   Anyone that has logged into their account lately may have noticed another tab at the top labeled ‘GIS Management.’   With this tab, BioBase users can take their data analysis and pretreatment assessments to the next level.

Although in development for quite some time, our team has determined that this powerful polygon tool is ready to launch for our users.  The polygon management tool allows subscribers to create a polygon within their data for automated processing and assessment of specific boundaries within an upload.  After you gather Lowrance sonar data and upload it to your ciBioBase account to create a bathymetric and vegetation abundance map, you can determine water volumes, acres, and max and average depths to perform analysis of specific areas of your coverage zone.  You’ll know where to focus your management efforts and have accurate details to help with the process.  By using the data you’ve already collected, the power of ciBioBase, and our TIN bathymetry output, you can create polygons and water volume estimates right in your account.  You draw the polygon lines, BioBase does the rest!  And the best part . . there are never additional charges once your data is in the System!

The days of estimating water volumes are over.  Even though we were already providing detailed water volume analysis of the area covered, ciBioBase will now allow you to create and manage your treatment zones and areas of concern in greater detail.  CI is taking lake management and habitat analysis to the next level and automating everything you need to take your collected data full circle.  ciBioBase is all you need!


Log into your account now to check it out!  This feature is available for any trip you’ve already uploaded to the System.  Not a BioBase user yet???  Give us a call to get started!  This feature is a perfect example of how we continue to innovate and make BioBase the best aquatic mapping and habitat software on the Planet.   There are no added costs or upgrade charges, just amazing feature updates.

We’re always interested in your feedback on the polygon analysis tool . . .

New Z-offset (depth offset) Feature

Some of our customers have requested the ability to make their maps even more accurate by eliminating the distance between their transducer and the bottom.  We listened! 
Depth calculations (z) using hydro acoustics are calculated from the source (transducer) to the bottom. Because a depth finder transducer is typically mounted below the water surface, depth readings are always off by the distance between the bottom of the transducer and the surface of the water . . . not anymore!   With the new z-offset feature, any user can now recalculate depths by entering this distance and reprocessing the trip.  For example, if your transducer is 6 inches below the surface, all of your depth readings should have a half foot added to them.  A 10 foot z should actually be 10.5” deep.  With a .5” z-offset, all of your depths will be reprocessed for better accuracy.  This is very important when calculating water volumes! 
The z-offset feature can also be used for calculations to high water marks or draw downs.  By using the z-offset for a 5 foot draw down scenario, our users can identify which bottom structures will be exposed as land (see below).  In addition, lake and pond managers can determine total water volumes at a high water mark by measuring this distance.  By simply offsetting all depth readings with a single z-coordinate offset, your trip will be reprocessed the way you want it.  Water volumes, blue scale, and plant biovolume will all be recalculated in your account.  Simple!
Below is an example of the z-offset in action for a simulated draw down.  We took an accurate trip from Trout Lake in Wisconsin and offest the z-coordinate by 20 feet to simulate a 20 foot draw down.  The new blue scale reflects the changes and displays the new land in green:
