Geospatial Analysis
Learning Outcome 1: Synthesize underlying geospatial concepts and apply them appropriately;
Learning Outcome 2: Critically evaluate forms of social analytics, applying appropriate techniques on social information;
Learning Outcome 3: Determine, design, prototype and implement geospatial applications;
Learning Outcome 4: Critically evaluate and identify emerging technologies and research areas relevant to geospatial analytics.
Task 1 - Descriptive explaining (2000 words, 50%)
a) Utilization of geospatial information are widely associates in social context with the support of different geospatial applications. (800 words, 20%)
Discuss the following topics/techniques in conducting a geospatial data analysis.
1. Coordinate Reference Systems
2. Techniques for manipulating Geospatial Data
3. Proximity Analysis
Your answer should contain the following key points. (But not limited to those.)
• An example describes real-world usage.
• A code snippet/s that supports your answer.
b) The usages of geospatial technology are very minimal in Sri Lanka, comparative to other countries in the world. (1200 words, 30%)
Resources management and Taxation are two (2) different geospatial applications, which can fulfill the current needs of Sri Lankans. Although, these applications can fulfill Sri Lankan needs, they are not being implemented in Sri Lanka, yet.Prepare a proposal to implement those applications in Sri Lanka. Following aspects should be incorporated in each proposal
- Need assessment
- Different types of data to be input
- Proposed functions / operations
- Expected output
You may refer Esri applications, but not necessary limit it.
Task 2 - Geospatial Application
Geospatial analysis can be applicable for the matters not only contexts in social, but also environmental, economic and political.
The objective of this exercise is focused to select suitable spatial regions for hospitals at Vancouver, BC. When building a new hospital, there are criteria that should be followed in order to find the most appropriate location. These criteria consist of required proximities or distances from certain features, such as roads and public washrooms.
Thus, the required criteria are as follows,
• At least 500m away from Existing Hospitals
• Closer (within 100m) to the Residential Area (Dwellings)
• Less than 100m away from Road
• Less than 100m away from Street
• Less than 100m away from Sub street
• Less than 200m away from Metro
• At least 500m away from Public Washrooms
• Less than 500m away from Fire positions
Use the existing CRS (EPSG: 26910) as project CRS and prepare a map to present your result.
Task 3 - Geospatial Modeling through Programming
Use of python/R programming to analyze Geospatial data in social context
You are provided all kinds of crime details during first six month of the year 2017 in Colombo Municipal Council area (1-15 divisions). Further details of schools and police stations are also provided. You may use graphs, charts or map, where necessary and explain your answer for following questions.
I. What are divisions having highest overall crime densities?
II. What is most occurring crime in each division?
III. Which month occurred the highest number of crimes in each division?
IV. Prove/disprove the statement - "Drug occurrence mostly occurs in the areas lesser than 150m from school".
