Geodata and geoinformatics
MetadataShow full item record
© Springer-Verlag Berlin Heidelberg 2013. Understanding the characteristics of and possibilities in using geodata is premised on proper comprehension of the underlying concepts of space, time and scale, contextualized within the Earth’s framework. Although these concepts are used in everyday parlance, often without much afterthought, they are not trivial at all. For instance, looking back throughout the entire history of mankind, the concepts of space and time have been the subject of animated philosophical, religious and scientific debates. In this section, we attempt to present a background of each of these dimensions of geodata, both independently and collectively, as well as highlight their relevance in influencing the character of geodata.

Featherstone, Will; Kirby, Jonathan (2002)A 9 arc-second grid of gravimetric terrain corrections has been computed over Australia using ver.2 ofthe GEODATA 9 arc-second digital elevation model (DEM) and the fast Fourier transform technique.This supersedes the 27 ...
Comparison of digital elevation models over Australia and external validation using ERS-1 satellite radar altimetryFeatherstone, Will; Berry, P.; Johnson, C.; Kirby, Jonathan (2003)Digital elevation models (DEMs) are widely relied upon as representations of the Earth's topographic morphology. The most widely used global DEMs available are ETOPO5, TerrainBase and JGP95E at a 5-arc-minute spatial ...
