Associated Geography - Overview:

The geographic features in this group may be better known to geo professionals - but many will not be. Your address, the property you occupy and the local authority area you live are all defined by geographic records.

The difference is that you cannot go out and see or touch any of these features as you can with a building or a river.

In many cases they are associated with existing natural or built features. Your property will most likely extend to a wall/fence/hedge or pavement edge. Likewise a local authority boundary can often follow the side of a rural wall, the centre of a river (or road). Some sections maybe "undefined" running between two physical points eg a boundary stone. Some like the extent of telecoms areas are variable.

The number of types of this group might be endless. To help illustrate the nature and variety of the forms of this geography we have adopted seven example types: administrative, cadastral, communications, electoral, habitats, postal and statistic.

Associated Features - Examples:

Property parcels are normally defined by a cadastral or land registration authority. In territories occupied by settlers these often tend to be uniform - based on a grid pattern. They may define residential properties (incl. apartments on multiple levels), rural farms and industrial sites as well as public land. Wher land has been settled for log periods the parcels can be very irregular and/or small where they have been split over time.

Statistical data are collected about all kinds of information to support planning and guidance eg births, deaths, the census, crime, accidents, traffic flows etc. While revealing the raw data is not usually published and is aggregated up into standardised areas. The units employed vary by country and include: Blocks [based on street blocks], Postcodes or aggregations eg Output & Super Output Areas and Administrative geography.

To support longitudinal reporting [eg causes of death over the last 100 years] it is important that the chosen geographic reporting area is stable over time. Unfortunately types such as postcodes are unstable.
