"Geographic Coordinate Systems" and "Projected Coordinate Systems" in ArcGIS and ArcMap
Let's take a look at the way ArcMap in ArcGIS understands projections. ArcMap uses things called "Geographic Coordinate Systems" and "Projected Coordinate Systems", which can be confusing because the terminology does not match what we use when we learn the theory of datums and projections. So, here is what ArcGIS means when it uses these terms. This way you can be sure you get it all correct, and can get overlay data correctly and accurately.

You are very welcome! I am glad the video was useful!
This video was super helpful, but I do have a follow-up question. If I'm creating a new shapefile in a specific US state, I should create a feature dataset that has a coordinate system of NAD 83; however, when I am creating the actual map I should use a projection in the data frame that more accurately displays the US State. Is this correct? Thank you so much!
Thank you
Thank you. Like the video!! But I hope to get more info about project coordinate system tho

If all data collected with GPS signal is collected in WGS84 then would it be safe to use WGS84 for all collected data in ArcMap?
Could we know the crs from measured point and the type of GPS
