To demonstrate understanding of key GIS concepts related to data and data storage

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.
