To demonstrate understanding of key GIS concepts related to data and data storage
carry out independent research on error issues in GIS.
“Whether a feature is represented as a point or a polygon in a GIS data base is entirely dependent on the nature of the phenomena itself.”
Review the issues involved in selecting a resolution for a raster GIS project.
What resolutions would be appropriate for the following problems: (a) determining logging areas in a National Forest, (b) finding suitable locations for backcountry campsites, (c) planning a national highway from Melbourne to Darwin?
Write an essay discussing the raster and vector data models. In your discussion include issues such as: the strengths and weaknesses of the two models, the costs of setting up the two data models, common sources of data for the 2 models, different scenarios in which one model would be preferred over the other, and why most spatial datasets have data in both formats. Give examples where possible.
