In the following assignment, you will build on what you learnt in the previous GlIS lab and develop further analysis. In the previous lab you created a map using a single layer. In this lab, you will utilise GIS' ability to spatially combine data from multiple layers to analyse several data themes to find suitable locations. Note: ArcGIS Online is web based. As such it can be completed on any computer with a web browser and internet access, although you will have access to laboratory computers. You have been asked by a tourism company to identify possible sites for locating a tourism site in Antarctica. This site needs to be flat ( < 5 degrees), reasonably big, below 200 m, and located in the Miers -Garwood region of the Dry Valleys within 80 km of Scott Base to allow for the required helicopter flights. The real objective of this exercise is for you to learn about overlay analysis in GIS. You will be required to produce a map (Part A) and answer the question above (Part B) in the form of a 1 page brief. In your brief, include an image of the site you have chosen showing key stats (e.g. area, preferably acres or km?), a link to your map in ArcGIS (i.e. your answer to Part A), and short discussion on site selection.
