I use the crystalsky with my P4P and was wondering about offline maps. Why would I need to download a map when the CS has a gps in it. Wouldn’t I get a map for where ever my location is?

The mapping data comes from the internet, the drone location comes from it's gps location.
DJI Go4 uses both to load the relevant map data for your flight location.
When you don't have an internet connection it can't download the maps, by caching the maps to the CS, there is a local source of map data for DJI Go4 to use.

Hotspot the CS to your phone and you'll get real time maps when you have a network connection.

You don't need maps anyway but some people like them.
But your GPS doesn't give you maps, it gives location data.
You won't get a map unless you download one.

I guess I’m confused as to what maps are. The gps gives me location on a map like my phone does when I use it to navigate to a location. It shows me where I am and where my drone is so I don’t understand what I would be downloading vs what I’m getting from the gps.

GPS just gives some numbers that indicate your drone's latitude and longitude.
The app translates the numbers to display where that location is, on the map that has been downloaded.

And the GPS in your controller is hardly used for anything.
The drone's own GPS receiver is what's used for all flight functions.

In the days prior to remote ID talk, offline maps where used in case a person didn't use internet data/hotspots. Now with what is being proposed in the remote ID you will be require to have some sort of internet connection to fly legally (not sure when it will take effect or how they will enforce it)

Understood but what I don’t understand is what the difference is between a downloaded map and what I get on the crystal sky with its gps. I get a 2D map with all of the area roads just like a gps in a vehicle. So what’s the point of downloading a map?
