HOW TO SUBMIT FILES FOR MAP GENERATION TIPS

Garmin Units: We can process files from Garmin GPS/Sounder units. Garmin *.gdb format, Garmin *.mps format, or GPS eXchange format. Check the track log and ensure a depth field is included in the information. Send this file via email or via our file submission page.

  • Garmin files are of minimal size. Email is the easiest send method.
  • Always keep a copy of the file sent.
Lowrance Units: Data processed from Lowrance GPS/Sounder units are from the Sonar Log recording Function. These files will be in the *.slg format. NEW!! We can now map BOTTOM HARDNESS from a sonar log file. Send this file via email or via our file submission page.
  • Sonar Logs are relatively large files. File submission page is recommended.

  • Sonar Logs usually can hold about a hour and a half of recording. User may need to save this file on their unit and start another recording. Sorry this is a limit of MS Excel the output format of the Sonar Log Viewer.

  • Download the Sonar Log Viewer from Lowrance.

Humminbird Units: In the works. Humminbird users need to process files from their SD card with the SON2XTF software available from Humminbird. Send the *xtf file via email or via our file submission page.
  • The Son2xtf software can be found under you Humminbird account. This should be the same place you downloaded your HumminbirdPC software.

Frequently Asked Questions

What is the best way to record information for file processing? Before we use to ask that you start and stop recording (tracks garmin, sonar log Lowrance) for each area you want mapped. Now with all our sounding in MS Access database just keep on fishing and recording.
How many sounding do you need for an area to be mapped? The more soundings for an area the better the detail of the map.
Any hints on mapping an area? If your mapping a shoreline area I like to fish close to the bank recording as I fish. I may fish again deeper and keep recording or just crank up the big motor and make a few passes recording the deeper areas off the bank. For off-shore areas I will make a grid with passes on the big motor or start on the structure and do an spiral outwards.
What do I get when I submit files for map generation? I will load your soundings into our database. I'll plot your data and look for areas that have sufficient sounds to generate maps. I will then extra data for those areas and return via email 3D maps, and topo map with Lat and Lon grids.
If I am a regular do I get more? Of course! We have a secure area of our web. Access to all maps for a particular lake are stored here. We'll give you unlimited access to that lake. We also offer this service for purchase.
What lake and how many maps on each lake is available in the secure area?
