Landscape Ecology and Gis

One of the difficulties which we faced as landscape ecologists was that, until quite
recently, the analytical tools available did not match the scale of questions we needed to
ask about landscapes. At the regional scale consistent data about the Earth’s surface and
its cover were difficult, time consuming, and expensive to collect. Large data volumes
also made processing complex and integration with other data difficult. Fortunately, with
the availability of computer-based systems for handling geographical or spatial data,
called ‘geographical information systems’ (GIS), many of these difficulties are beginning
to be overcome.
In this book we use the term ‘GIS’ in a very general way to describe any computerbased
system for the input, storage, analysis and display of spatial information.
