  • GIS for Educators - Topic 10: Spatial Analysis (Interpolation)
    Sutton, Tim; Dassau, Otto; Sutton, Marcelle (2011-08-08)
    Understand interpolation as part of spatial analysis. Spatial interpolation is the process of using points with known values to estimate values at other unknown points. In this worksheet we describe interpolation in more ...
  • GIS for Educators - Topic 1: Introducing GIS
    Sutton, Tim; Dassau, Otto; Sutton, Marcelle (2011-08-08)
    Understanding what GIS is and what it can be used for. With a GIS application you can open digital maps on your computer, create new spatial information to add to a map, create printed maps customised to your needs and ...
  • GIS for Educators - Topic 2: Vector Data
    Sutton, Tim; Dassau, Otto; Sutton, Marcelle (2011-08-08)
    Understanding of vector data models as used in GIS. Vector data provide a way to represent real world features within the GIS environment. A feature is anything you can see on the landscape such as houses, roads, trees, ...
  • GIS for Educators - Topic 3: Vector Attribute Data
    Sutton, Tim; Dassau, Otto; Sutton, Marcelle (2011-08-08)
    Understanding the role of attribute data in a GIS. Attribute data describe features. Attribute data can help us to make interesting and informative maps, and perform spatial analysis in a GIS application. In this topic we ...
  • GIS for Educators - Topic 4: Data Capture
    Sutton, Tim; Dassau, Otto; Sutton, Marcelle (2011-08-08)
    Learn how to create and edit vector and attribute data. In the previous two topics we looked at vector data. We saw that there are two key concepts to vector data, namely: geometry and attributes. The geometry of a vector ...
  • GIS for Educators - Topic 5: Raster Data
    Sutton, Tim; Dassau, Otto; Sutton, Marcelle (2011-08-08)
    Discover the different kinds of raster data and how they can be used in a GIS. Raster data are arranged in a matrix of cells. Each cell in the matrix has a value. When viewed as a whole the raster looks like an image. In ...
  • GIS for Educators - Topic 6: Topology
    Sutton, Tim; Dassau, Otto; Sutton, Marcelle (2011-08-08)
    Topology defines the relationship between vector features. In this topic we look at how topology is used in a GIS, and the differences between topological and non topological datasets. We also look at how topological ...
  • GIS for Educators - Topic 7: Coordinate Reference Systems
    Sutton, Tim; Dassau, Otto; Sutton, Marcelle (2011-08-08)
    Coordinate Reference Systems (CRS) provide a system for specifying location. In this topic we explore why CRS are needed and look more closely at the advantages and disadvantages of different CRSes.
  • GIS for Educators - Topic 8: Map Production
    Sutton, Tim; Dassau, Otto; Sutton, Marcelle (2011-08-08)
    Understanding map production for spatial data. Map production is the process of arranging map elements on a sheet of paper in a way, that even without many words a layperson understands what it is all about. Maps are very ...
  • GIS for Educators - Topic 9: Vector Spatial Analysis (Buffers)
    Sutton, Tim; Dassau, Otto; Sutton, Marcelle (2011-08-08)
    Understand the use of buffering in vector spatial analysis. Spatial analysis uses spatial information to extract new and additional meaning. Usually spatial analysis is carried out using a GIS Application. A GIS provides ...
