Question 1.

Create a map for an area of your interest by downloading vector data (i.e. point, line & polygon) and spot heights from the Internet (Web). Your map should contain at least one layer for each of the following data categories.
• Point layer showing point features
• Line layer showing linear features
• Polygon layer showing areal features, and
• Spot height showing elevations
(Notes: You may download vector data from OpenStreetMap and spot heights using Zonum Terrain Solutions platform or any other spatial data source suitable for your map. You can use the Map Composer feature in QGIS, or in any other GIS software).

Requirement:

• Present your map on a single PDF page.
(Note: For full marks, all aspects of your map must be legible on an A4 sheet and incorporate attractive graphics and a sensible colour scheme).
As a guide the map should at least include;
(i) Title,
(ii) North arrow,
(iii) Scale bar,
(iv) Legend, that contains
• Units for the elevation spot heights
• Meaningful names for the different types of point, line and polygon features (don't use generic names line "line").
(v) Text box showing
• Datum
• Coordinate reference system
• Data sources
• Map author-name
• Map author contact details
(vi) Geographic reference grid around the outside of the map
• Ensure the coordinates in the grid are consistent with the CRS listed in the text box
(vii) A Neat Line around all map elements
(Note: refer to A Gentle Introduction to GIS: Map Production chapter as a guide).

Question 2.
This question is designed to test your ability to use Vector Proximity, Overlay, Clipping and Query and Attribute Table analysis techniques.
(Note: If you try to answer the question by using the measuring tool and counting the bores you will most likely get the wrong number and in any event, you will receive a low mark for not using the correct GIS approach).

The required data for the area surrounding the town of Chinchilla, Queensland, Australia is in the attached Assignment_Q2 data.zip file. Please answer the following questions on the Form provided
a) How many water bores are within 20 km of the Chinchilla built-up area?
b) How many gas bores are within 20 km of the Chinchilla built-up area?
c) How many gas bores are within 500 m of a major or minor stream and within 20 km of Chinchilla built-up area?

Requirement:
• Present a screen-captured image (or map) of each analysis area illustrating your results. Screen captured images (or map) may be reduced in size to ½ page each. Please ensure that the target bores remain identifiable in the map image.

Question 3.
This question is designed to test your understanding of the conversion of vector data to raster data. Convert each vector file into a raster file. The required data is in the attached Assignment_Q3 data.zip file. Use the appropriate GIS Vector to Raster conversion methods and select suitable scales so that the converted data is legible when in raster format.
a) Point vector file should preserve the type of place (Attribute = "PLACE_TYPE").
b) Road Line vector file should preserve the type of road (Attribute = "FTYPE").
c) Drainage Line vector file should preserve the elevation of the drainage feature (Attribute = "ELEVATION").
d) Cadastral data polygon vector file should preserve Tenure (Attribute = "TENURE").
(Notes: Data provided include both categorical and continuous types. Continuous values are best presented using a progressive colour ramp. Use 5 categories and show the elevations in meters. Categorical values are best presented using a discrete (non-progressive) colour ramp with a different colour for each feature type. Label the legend for each map to show feature categories).
Requirement:
• Present clear and legible answer.
• Use maps or screen-captured images (½ page each) that show the attribute values visualised as categories of different colours and labelled appropriately.
• Ensure all legends are clearly readable.
• What resolution did you use for each conversion and why? Present your answer in the following table format.

Question 4.

Identify seven key issues to be considered when sourcing GIS data from the Internet (Web). Describe how you would address each of them.

Requirement:
• Present your answer in a table that identifies the issues and provides details on how you would address each issue.
(Note: Cite references using Harvard AGPS system where applicable).

Question 5.

This is a GIS planning question and is designed to tie the different GIS processes you have studied together. You are NOT REQUIRED to download data-set or use GIS software to answer this question. However, you are required to; nominate a specific community, identify (only identify not obtain) spatial data sets needed, and describe the sequence of GIS operations used to reach your objective

Background:
As a GIS consultant, you have been asked to identify a location (site) suitable for the development of a 'Public Park' for the community you have nominated. You have been asked to apply following site selection restrictions.
a) The park has to be at least 1 hectare in size.
b) The park should not be more than 5 kilometres away from the centre of the populated area.
c) It should be located on public land.
d) It should be on the ground that is relatively flat (less than 3% slope).
e) It should not be in a location that is subject to flooding.
f) Public toilets should be within 500 m.
g) The park should have easy access (within 500m) to public infrastructure that includes;
i. roads,
ii. mass transit (bus or train if applicable),
iii. electricity,
iv. water supply, and
v. drainage.

Your task:

• Identify an urban community that is near where you live.

• List all the spatial datasets that will allow you applying above listed site selection restrictions. (Notes: As an example, you might identify 'rail network' data set if the site has to be within 500 m distance from the nearest train station. Please provide the name of the dataset that is searchable in a spatial database (e.g. 'rail network' not train track)

• Explain the series of GIS processes you would go through to arrive at a final recommendation of a site for a new park that meets the above criteria. This should identify the process, the data set it would operate on and the resulting product. These should ideally be linked together in a flow diagram that leads to the final recommendation.
