Database
Do you need to make spatial query? Do you need to immediately display the sample locations in which the results are higher than the defined threshold? Do you want to overlay the results with geological map?
GIS give opportunity to make queries for spatial and non-spatial data.
You can store information for all the elements on your map into the database and you can easily acquire the desired information on any requested time with the help of GIS. Additionaly, you can make analysis, evaluate the results and produce appropriate outputs for your goal.
