A snapshot of the summary - Literature Spatial Analysis and System Modelling

  • 1 Time

  • 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.
  • 2.3 Thiessen Polygons

    This is a preview. There are 1 more flashcards available for chapter 2.3

  • 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.
