Time and GIS: Ways of Representing Time on a Map

Spatialtemporal visualization are ways to illustrate changes in an area over time on a map. The famous geographer Immanuel Kant maintained that geography was the study of knowledge in a location, while history was the study of knowledge in time. This article explores different cartographic methods of showing changes in time over space on a map.

Area Cartogram Maps Explored

Area cartogram maps are maps of non-absolute space where the areal extent is in proportion to some measured value.  Cartogram maps retain a partially accurate relative location and relative space, but the actual area of the individual polygons features are overrepresented or underrepresented based on the assigned values. Area cartograms […]

Cartographic Capabilities in ArcMap

Cartographic Capabilities in ArcMap

The release of ArcGIS 9.2 brought increased cartographic capabilities to ArcMap especially in the area of rendering. As with last year’s conference, this was evident by the range of technical workshops offered at the recent ESRI International User Conference held this past June. On hand at the conference were ESRI […]
