1.3 Spatial-Temporal data model
-
What are spatio-temporal data models?
They are ways of organizing representations of space and time in a GIS -
What are spatio-temporal analysis?
Consideration of changes of spatial and thematic attributes over time -
What is object motion?
Both spatial and attribute domains are variable and consider how fields or objects have changed over time -
1.4 Webbook: Spatial data models and methods
-
Where should you be aware of with data manipulation?
Almost always will the data in both expected and unexpected ways, in many instances resulting in some loss of information -
What is T-mode data?
The recording of complete spatial fields at distinct points in time, views as a set of time slices (typically in fixed time intervals) -
What is S-mode analysis?
Is complete spatial fiels recorded at distinct points in time, viewd as a set of point locations or pixels, each of which has a temporal profile --> space-time cube -
What is Agent Based Modelling?
The application of a range of microsimulation techniques -
2 Raster Analysis
-
2.1 Vector Measurements
-
What is distance measurement?
The computation of the minimal distance between a location occupied by the first feature and a location occupied by the second feature -
What is area size measurement?
Is associated with polygon features. -

What are Thiessen polygons?
Polygons that make use of geomeric distance neighbourhoods. This is useful if we have a spatially distributed set of points as target locations and we want to know the closest target for each location in the study. . This technique will generate a polygon around each target location that identifies all those locations that “belong to” that target.
