Merge sonar logs from multiple trips for complete maps

To ensure quick uploads and prevent file corruption, makers of Insight Genesis custom lake maps can record several smaller sonar-log files while on the water, then merge those logs later into a master lake map. This is especially beneficial to Genesis users that prefer to make their fishing maps while actually fishing.

Depending on the size of the lake, creek arm or river section you’re fishing, you can create a complete, custom countor map from multiple sonar logs recorded in a single day or over multiple days, and with no complicated computer programming required by you – Insight Genesis’ innovative Cloud-based processors do all the work. That’s one of the many benefits of a Premium Genesis subscription over a free account. Other benefits include custom bottom-hardness and vegetation-location maps.

Follow these easy steps to merge multiple sonar log files into a master map:

  1. Click the “Merge” tab in your interactive Genesis viewer to see a list of your sonar logs from the same water body, organized by date.
  2. Select the files you’d like to merge by checking the boxes and clicking “Merge.”
  3. Watch your email in-box. You’ll receive an email when the Genesis processors are done merging your data into a single, custom map.

Upload speeds depend on sonar log size and your Internet connection speed. Map-creation speed is based on the size of your logs files and total data size. The size of the water body might also be a factor. Recording multiple, smaller sonar-log files can provide better results, especially for Genesis users with slower Internet connection speeds. Click over to this blog post for tips for recording smaller sonar-log files.

    1. Tim: To merge more than 12 trips into a master map, you’ll want to upgrade from a free account to a Premium account. A Premium account will also give you bottom-hardness and submerged vegetation-location map layers — very powerful tools for identifying and expanding on successful patterns.
