New to this system Dji S1000 and Inspire advice

All that matters is the camera. So as long as you can capture enough overlap you should be good. Waypoint mission with the 5D intervalometer might be enough to get started, just make sure it’s set fast enough to get overlap.

Just make sure that you fly at the right height for the accuracy you want. Mission Planner has a tool that lets you compare pixel resolution if you have a sample image, or you can just enter values on Pix’s calculator.

There’s also the app for the Inspire 1 but it’s still in testing, https://community.pix4d.com/t/4828.
