I am trying to set up a system to capture latitude, longitude and bottom depth
. This is for a small harbor with shoaling issues. We would use the data to put on a mapping system to show where to dredge.
I have a Lowrance Elite 5 sonar-chartplotter. The manual says that there is an NMEA
output socket which also could be used to connect a temperature gauge or speed log. I called a tech person at Lowrance and they said they did not have connectors and that there was no NMEA
output. Should I believe them and just get another sonar-chartplotter?
Assuming it is possible to use the Elite 5, where can I find a connector for the Elite 5 to connect to a laptop
? Should I be looking for a usb connector or serial
connector on the laptop
side? Is it a direct connection or is there some circuitry between the sonar-chartplotter and the laptop?
What program can I use to log the NMEA output?
I have OpenCPN
working with charts
on the laptop but have not used a gps
connector. The laptop is running Windows.
I am not averse to trying to wire up a connector, if I could figure out a way to make it a reliable and solid connection.
I would use the NMEA textfile output to import
into a spreadsheet, delete the unwanted columns and name the fields in the first line, then import
the resulting lat/long/depth into an ArcGIS system to display depth
on a chart of the river.
