How is geodata used in kayak fishing?

Hi everyone,

I’ve recently gotten more into kayak fishing, and I started wondering how geodata might play a role in planning trips or improving the overall experience. I’m guessing it can be useful for mapping fishing spots, checking water depths, or tracking conditions—but I’m not sure what tools are actually out there for this.

Are there any apps or platforms that combine GPS with detailed geographic data specifically for kayak anglers? I’m also curious whether people collect their own location data over time to build a kind of personal fishing map or log.

If anyone here uses geodata while kayak fishing or knows where to start, I’d love to hear how you integrate it into your routine..

Thanks in advance.
