Export BioBase EcoSound Maps as Lowrance Charts

2020 has been a busy year for BioBase improvements and new feature releases. Previously exclusive to BioBase’s sister consumer mapping platform, C-MAP Genesis, BioBase users can now export their bathymetric, aquatic vegetation heatmap, or bottom hardness map in a file format (AT5) that is compatible with most newer generation Lowrance and Simrad chartplotters. This feature enables researchers and aquatic resource managers to return to surveyed areas of interest and precisely target follow-up surveys or management actions (e.g., strategic taking of water or aquatic plant samples, placement of fish habitat structures or aeration equipment, precision applications of aquatic herbicides, etc.)

In the images and captions below, we’ll walk you through how to do this in your biobasemaps.com account.

  1. Register your Lowrance or Simrad Chartplotter in your BioBase Account
PlotterScreenshot
Assuming you have already recorded your sonar data and successfully uploaded to biobasemaps.com, log into your BioBase account. Click “Plotters”
AddDevice
Add unique details of your chartplotter. This feature is compatible with most newer (newer than 2014) Lowrance and Simrad GPS capable devices (e.g., Lowrance HDS, Elite Ti and Ti2, Simrad GO and Evo)
LowranceSystemAbout
Look in the “About” menu of your Chartplotter. Image above is from a Lowrance HDS Carbon.
SerialContentID
Look for the Serial Number and Content ID alphanumeric code. Enter these into the plotter form on biobasemaps.com

2. Export the GPS Chart file from the desired EcoSound Trip or Merge from BioBase.

ExportAT5
In the Export Data tool, select “GPS Chart Generation”
GPSChartGenerationModal
Export the desired layers

3. Unzip the downloaded file and save to a MicroSD card (<32 GB).

7-ZipAT5
The layer will export as .zip with a random GUID name. The zip file must be unzipped (7-Zip is a great freeware for unzipping files) and the entire contents of the extracted zip file should be copied to a MicroSD card. The contents in the folder are propriety, encrypted files (.AT5) that are specific to the device you registered in your account. The chart file will not work in other non-registered devices. You can register multiple devices. One card can hold multiple AT5 folders (charts) and recorded sonar logs. Cards cannot be larger than 32 GB however.

4. View and Use in your Lowrance or Simrad!

Insert the card with the saved AT5 chart files. Go to the Chart and select the appropriate Chart Source in Chart Options. Voilà!

If you want to view a blue- (or custom-) shaded contour map, simply uncheck the Vegetation/Composition categories in one of the Chart menus.
