P13 Manipulation and analysis

PirroNord_wiki|PirroNord wiki

As well as recording information such as that suggested above, most of which will probably only need recording once when you start work with a data set, it is also extremely valuable to log the manner in which data are manipulated and modified. Not only does this allow you to keep track of — and back–track from, if necessary — changes you make to the data, but it also allows you and others to work out how data you lifted from your local Sites & Monuments Record, for example, and incorporated into your own GIS differs from those same records still residing in the SMR.

The aims is not to perform 'an analysis' to produce 'the answer' but rather to execute successive passes through the data gradually identifying trends and patterns that look interesting and can be followed up by futher investigation.
