gps moving map on ILI9341 240x320 TFT

[chuckmerja]

I had several students use ILI9341 TFT and ESP32 to display thermal sensor and force sensor array info this year, thanks to finding you and your repo!!!
I was using my ATV sprayer yesterday when I thought it would be great to have a display of where I'd sprayed and so I started thinking about combining a GPS Cow tracker project with an ILI9341 screen to display a map of my spray job. I can already get the tabbed data into a nano, ESP32 or UNO/MEGA - see attached data string example. We can bring that data into a computer and display in google earth or another GIS, but I'd like real time, on the ATV display. I am a farmer, so I have multiple thousands of dollar devices that steer the tractor and provide "coverage maps", but I'm thinking I can DIY something for the ATV..
I'm wondering how to scale it so that LAT/LONG are displayed on the screen. Any hints would be welcome!!
