I was given a point shapefile that does not have coordinate system. So, I need to specify it. I was told that this have following reference system.
- Coord. Sys. – 17 South (UTM)
- Units – US Survey ft
- Datum – WGS 1984 (7P)
- Geoid model – GEOID12A (Conus)
I have never seen options for specifying Geoid model in ArcGIS, and also, I have not seen WGS 1984 (7P). Except this, I am familiar with other information. These two things are confusing me. Will I be fine if I just use WGS_1984_UTM_Zone_17S?
Can someone help me if this is fine. Please suggest.
