General guidelines The Portfolio Assessment requires you to submit work from three practicals: Part 1 – Hydrology Tools (Practicals A&B) and Part 2: Lynx Habitat exercise. Submit your portfolio as a single document, using a style that is consistent throughout the portfolio. Include: • Title page for the document plus title pages for both parts 1 and 2 • Figure/table numbers for all figures (including map and diagrams) and tables • Captions for all figures and tables describing what is presented. • Citations and reference list using the APA 7th edition style • All maps should include all the essential elements of a map: legends, scale bars, north arrows and place names as required. Page limit: 20 pages max. Part 1: Hydrology Tools Practicals A and B Task 1: (1 x map) Create a layout of the Strahler stream vectors to include the hillshaded layer plus the altitudes contained in the Hydro2mDTM layer. Use a sequence of colours and line thicknesses for the streams to show the Strahler hierarchy. Include legends for the altitude and the Strahler stream classification. Add scale bar, north arrow and the source of the data (The Environment Agency). Export your finished map as a JPEG by using the Share menu. Change the resolution to 300 dpi (dots per inch). Task 2: (1 x diagram) Provide a complete model diagram to replicate all the catchment analysis steps in Practical A, plus the addition of the following: ▪ A catchment statistics table for slope ▪ A catchment statistics table for altitude ▪ A hillshade for the topographic map Task 3: (1 x map) Using the data produced by your model, create a map showing the Strahler stream order together with a hillshaded layer and altitudes for the Palmer’s Brook catchment (i.e. a similar map as that produced in Task 1). Remember to include scale bar, legends, north arrow and data source. Export your finished map as a JPEG by using the Share menu. Change the resolution to 300 dpi (dots per inch). Task 4: (500 words) Write a short report (no more than 500 words) describing the Valency and Palmer’s Brook catchments in terms of their topographic characteristics and suggest reasons why the Valency is more susceptible to the Principles of GIS – Portfolio Assessment 2 kind of catastrophic flooding that occurred in 2004. Use other data sources as you wish, including citation and referencing to relevant supporting studies or articles. Part 2: Lynx Habitat Modelling Task 1 (1 x table, 1 x map, 1 x diagram plus 500 words) 1. Provide a table that shows: a) Area of each patch (Km2) b) Total area of woodland within each patch (Km2) c) Percentage of woodland within each patch. 2. Create a map that shows the patches and corridors superimposed on the topography. Include place names and key topographic features as part of your final design. 3. Provide a final copy of the SuitabilityModel. 4. Examine the patches and the corridors using the Basemap OpenStreetMap layer as a backdrop. Assess the likelihood that a sustainable lynx population is possible within the patches and would be able to use the corridors between the patches. Having completed this, what measures could be taken to increase the likelihood of success of reintroducing the lynx to Scotland (500 words max.). Task 2 (1 x table, 1 x map, 1 x diagram plus 250 words) 1. Repeat steps 1 – 3 above in Task 1 but try to refine the analysis by including proximity to roads as part of the suitability analysis. You can download road data from Ordnance Survey’s Open Roads: https://www.ordnancesurvey.co.uk/business-government/products/open-map-roads. You may want to clean-up this dataset first (i.e. remove minor roads) and then follow a similar workflow as to that already applied in the model with respect to proximity to streams. 2. Provide a 250 word description of your method for including proximity to roads in the suitability model.
