In the last chapter, we examined various methods that can be used to create individual items of
geometry data, for example, using a static method that accepts WKT or WKB input, or using one of the
SqlGeographyBuilder classes. Each of these methods creates only a single item of data at a time. So what if you wanted to import an entire set of spatial data?
In this chapter, I will introduce you to some of the sources from which you can obtain publicly available sets of spatial information, examine the formats in which those datasets are commonly supplied, and teach you some of the techniques you can use to import that information into SQL Server.
