Italian to English Social Sciences Mining & Minerals / Gems Collection of minerals

This is from an article on a collection of minerals.

Essa comprende quasi esclusivamente campioni di selce, frutto di una raccolta selettiva sul territorio compiuta dai donatori, puntualmente corredati ***dall’indicazione su cartografia dei punti di prelievo***.

I am reluctant to use cartography here as that seems to be connected with the science/technique of drawing maps, etc. I have "...carefully labelled with indications on the map of the sampling (collection?) points" but I'm looking for confirmation and/or alternatives. TIA
