With developers digging left, right and centre nowadays, it is important to first know exactly what lies beneath. Within towns and cities, it is now common to use an urban survey to find this information out. Using the GPS technology, urban surveys are now easier and more accurate than ever.

Before any kind of building development can commence in an area, it is first essential that a survey is undertaken of the ground below in order to ascertain what lies beneath. For instance, a survey may uncover ancient vaults or crypts that may lie nearby the area. But also from a practical point, a survey can tell you where the nearest water source is available underground.
A prospective developer will arrange for a survey of the area, prior to any digging, in order to gain that extra knowledge and discover exactly what is beneath the surface. These surveys fall under various different categories including, but not limited to, Geophysical and Topographic surveys. In addition to these, an Archaeological survey can also be done on sites where there are historic buildings and churches, or even just rural and urban sites.
In respect of an urban survey (an investigation of an area that would take place within a town or a city), it is common for the evaluations to often require slightly different demands in order to ascertain the prospect of any archaeological presence. The depths of the deposits for instance, are much greater than they would be on a rural site as only an inexpensive reconnaissance survey would be required there. As well as the depths of the area, the stratigraphy of an urban survey is often much more complex and the conditions of the surface itself are significantly more complicated due to the general wear and tear that is caused by the daily comings and goings of busy town and city folk. In an urban survey, the most common targets that are found include building foundations, industrial archaeology, town ditches and walls and former road surfaces.
An urban survey of a site will help to determine what, if any, archaeological articles are present in that particular area of the town or city. This information then permits the developer to consider their options; are they able to proceed with the building development or not? It can also provide archaeologists with an idea of whether or not that particular site could be of some importance to them in any ongoing studies they may have of the area.
We’ve all heard of "Sat Navs" that use GPS (Global Positioning Satellite; well this relatively new technology is now being used within the survey industry. Due to the complexity of this technology, a surveyor is consequently provided with very accurate results when performing a survey and it can provide immediate access to the exact plans, locations and sizes of buildings; this can be extremely useful when we are talking about an urban survey. In addition to this, the more recent use of GPS within this industry subsequently means that an urban survey can now be done in a more accurate, simpler and speedier way than it would have been done previously.
With urban surveys now being quicker and more accurate than ever, it is swiftly becoming common practice to use this method in order to find any potential important archaeological findings within a town or city. If not, then the developer’s brand new tower block plans can go ahead without any glitches.
