The image above is a map of elevation above sea level created in ArcView
and made into a gif image using XV. To create the input data the source
data was imported, projected into a 1DM geographic projection and ouput
as an ascii file using the following commands within ArcInfo:
Source data=GLOBE: Global Land One-KM
Base Elevation Data version 0.1
Elevation and relief relate to and effect settlement patterns and accessibilty.
Building technology and the ability to supply goods and services seems
to continually be improving. Nowadays houses can be built right on the
edge and in remote regions without being totally isolated.
Lowland areas generally have higher population densities than highland
It is unlikely that large population densities will be observed in over
extremely rugged terrain. Relief limits the availablility of appropriate
sites for large developments and is obiously a major constraint to communication
and transportation development and thus the functionality and size of settlements.
From the image above it is clear that Europe has a great range of relief
more varied than that found in the Great Britain. It is likely that the
relationship between elevation, relief and population density in Great
Britain is similar to that in the rest of the EU, but for some areas the
relationship could be radically different. Regional geographical knowledge
about the relationship between relief and population should be useful when
adjusting population surface outputs.
