Problems creating satellite image tile (tpk file) without ArcGIS license

Good morning,

I’m trying to make use of the GIS functionality for an agricultural survey to measure farm size. I’m having problems creating the .tpk map tiles for the survey areas (12 small areas of around 5km2 in rural Nigeria) since I don’t have an ArcGIS account.

I think that there is a way of doing this using a free web tool, but am having problems finding this - could you please point me in the right direction?

Many thanks,

Since you will likely need both the tool and the data, perhaps, your best bet is to contact the National Bureau of Statistics of Nigeria:
