	A place in history: a guide to using GIS in historical research CHAPTER 3: ACQUIRING SPATIAL DATA
	3.10 Conclusions Acquiring spatial data is usually either time consuming or expensive or both. It is not to be entered into lightly. Once spatial data are available in digital form, however, they become a powerful resource with uses that may go far beyond the original use for which they were captured. It is important to remember that digital spatial data have all the limitations of the original source data, be they maps or other sources, plus some additional limitations and errors introduced by the data capture process. As will be described in Chapter 9, good documentation and metadata are essential elements of the data capture process, as this allows other users to evaluate the fitness of the data for their purpose. This ensures that data are widely used but only for purposes that they are fit for.
