Module 3 – LiDAR
Case Study
Watershed Name: Wheatley River Improvement Group
Location: Wheatley River, PEI
Areas of concern: Risk of excessive erosion due to steep slope near streams.
Watershed Stats (area, land use, human resources, budget, photos, maps, etc.):
WRIG consists of 6 sub watersheds and is 8,819 Ha (88.2km
2
) in size
Land use:
o
Agriculture – 69.5% o
Forest – 21.9% o
Developed – 7.2% o
Wetland – 1.4% In this case study, LiDAR has been identified as the most appropriate technology for collecting the relevant data. Follow these steps to complete the case study:
1.
Review the information provided. 2.
Answer the questions and complete the project requirements table in this document. 3.
Once you have completed the case study independently, watch the video (in SAM) to self-check your responses. Be sure to make note of the correct answers, as these will help you when you complete your final project.
4.
Watch the case study demonstration video (in SAM), which walks through the steps of accessing the relevant data and working with it
in QGIS. Follow along and use the steps to help inform your data-
based decisions for your final project.
5.
Use the Learner Workbook to take note of your learning and reflections. Be sure to reference these notes when you complete your final project.
Module 3 – LiDAR
Case Study
Resolution & Accuracy – Do you need high resolution imagery? Do you require accurately georeferenced data?
Coverage Area –
How large is the area you are looking to cover? Budget & Financial – What financial constraints are in place?
Timing of Data –
Do you require up to date information or is previously collected data suitable?
Data Sources & Storage – Where will you source the data? Do you need to collect it yourself? Outputs Required – What outputs are required to achieve your goals?
(e.g
.,
Orthomosaic, digital surface model, slope map, measurement, etc.)
Analysis Software – What software will be required to work with your data? Additional Considerations-
Is
there anything else you will need to consider? (e.g.
,
environment, weather, IT, human resources, etc.)
Project Requirements
Case study questions:
1.
Why was LiDAR selected for this project? 2.
How and where would you source or collect the required data?
3.
How would you use GIS software to generate your required outputs from the data you source?
4.
Why would this information be valuable for the Wheatley River Improvement Group?
