ENGM285 (2023/24) Computer Lab 1 Geographical Information Systems 1 Getting started This practical intends to give an exciting introduction to GIS through hands-on experience on two (near) realistic exercises making use of real data. The tutorial is ArcGIS based. In order to do the exercises you need to install the ArcGIS Pro version 3.0 or higher on your computer. Importantly, you need to install the Spatial Analyst extension as well. You should have received a link to the software and license codes from FEPS IT Support. This will allow you to install the software on a Windows computer. If you do not have access to a windows computer, you can log on the Enhanced Virtual Desktop on https://it.surrey.ac.uk/off-campus- access/virtual-desktop. On-campus the software is already installed on the computers in the AA building (room 28/29 AA 02, 5 AA 02). After installing the software, you will need to install the data that is used for the tutorial. The data is present on the ENGM285 SurreyLearn page, as the files exercise_1_pro_package.mpkx and exercise_2_pr_package.mpkx. You may have guessed that mpk stands for map package. Download these files to a convenient location on your own computer. Do not double-click on these files, you will have more control about where to unpack the data if you open them through the ArcGIS interface.

First start the ArcGIS Pro software; this is only one of the programs installed in the ArcGIS package, so be sure to start the right program (Figure 2).

Click on "Start without a template". Next, find the Analysis ribbon and within that the Toolboxes button. This will give you access to the full range of analysis tools offered by the app. (Figure 3): In the window that opens find the tool Extract Package that sits within the Package group that in turn sits within the Data Management group. Click on the tool to start it. In the tool, specify the exercise_1_pro_package.mpkx file that you wish to unpack as well as the directory where you want to unpack it to (Figure 4). Note: It would be attractive to place your files on OneDrive, but regrettably OneDrive and ArcGIS do not work well together. Therefore we will work on a folder on the C drive and package up our files in a zip-file at the end of a session and copy the packaged file to OneDrive. 1 Project Map Insert Analysis View goa ModelBuilder Pyth▾ History Ready Tools Environments Use Tools Analysis allery 2 al Geoprocessing Contents ☑ Tools ДХ Untitled Edit Imagery Command Search (Alt+Q) Share Help Data Engineering Explora Suitability Modeler Networ Feature Raster Analysis Analysis Visibility Analysis Neighb Portal Geoprocessing Extract Package Extract Package (Data Management Tools) 3 Extracts the contents of a package to a specified fo of the input package.

Any resemblance to real persons or organisations is purely coincidental. The Water Management Region "South East" consists of four Water Management Areas: West Thames, North East Thames, Kent & South London, and Solent & South Downs. The region has a fixed budget for flood protection and wants to use an objective method of distributing the funds over the four areas. Following lengthy negotiations, it was decided that the funds will be distributed by ratio of the exposure to flood risk. The agreed method for quantifying exposure to flood risk is an overlay of the flood hazard map with the land cover map. The land cover class Continuous Urban Fabric gets a weight of 1, Discontinuous Urban Fabric gets a weight of 0.8 and Industrial or Business Land gets a weight of 0.6. 1. Work out the distribution of the budget. 2. One of the WMA's suggested using exposed population rather than land use as the subject of exposure. Which area would that be? Give arguments for and against this alternative. 3. What limitations do you see in the followed procedure? 4. If you could introduce one additional variable to the analysis, what would it be? And why! Data provided: • Land cover (CORINE dataset) • WMR outline • WMA outline • Flood Hazard map 4 Exercise 1: Guidance 1. Log in to a computer with ArcGIS Pro installed 2. Follow the steps in 'Getting Started' to unpack the data on your computer 3. Start ArcGIS Pro and start a new "Project", using the option "Start without a template. 4. Go to the "Insert” tab and "Import a map". open the 'map file' exercise_1.mapx. (Figure 5) Untitled Comma 5.

Key information Module name Unit of Assessment Unit of Assessment weighting Submission date Learning outcomes ENGM285 - Geographical Information Science and Remote Sensing Assignment 1: Geographical Information Science 20% 26 February 2024, 4pm Be capable of applying GIS tools to engineering/environmental problems Be able to critically evaluate data, analysis techniques and results 2. Task The coursework is to finalize and prepare a report on Exercise 2 of the GIS Practical of Lab Session 1. The exercise asks you to propose a location for a Waste Water Treatment Plant. The question prescribes five criteria for finding a location. You are then asked to prepare a suitability raster layer for each of these criteria. Present each map in your report and explain the methods and tools used to create the map and the rationale for using this method. You are expected to use overlay analysis to combine the raster layers into a single layer indicating overall suitability as a Waste Water Treatment Plant location, discuss your findings and draw a conclusion based on your analysis. Discuss critically what you consider to be the strengths and weaknesses of the followed approach. How robust do you consider your findings? What are the major aspects of uncertainty? Present the report professionally. The maximum length of the report is 8 pages, including cover page and figures, but it should be possible to complete it to a high standard in 4 pages. Submissions must be in PDF format and submitted via the Assignment folder on the ENGM285 page on SurreyLearn. 1 3. Marking Criteria The report is marked according to the following criteria: • Professional presentation (20%) . • • о This includes: precise and technically correct language, styles and formatting, referencing, numbered captions for figures and tables, map presentation, conciseness and clarity Use of GIS tools to operationalize given criteria (30%) о This includes: applying appropriate GIS tools for each criterion and applying correctly. Where appropriate justify choice of parameters. Use of tools to combine criteria and select location (30%) ○ This includes: choice and justification of equation for combining criteria, where appropriate normalisation of criterion scores, a balanced interpretation of results to select possible locations Critical reflection in discussion and conclusion (20%) ○ This includes: a reasonable assessment of the effect of uncertain factors and arbitrary decisions in the outcome of the analysis, an appreciation of both the possibilities and limitations of the approach and the role it can have in decision making. The University Grade Descriptors for Level 7 will be applied when marking. 4. Marking template Criterion 1. Professional presentation Weight Mark Comment 20% 2. Use of GIS tools to operationalize given 30% criteria 3. Use of tools to combine criteria and 30% select location 4. Critical reflection in discussion and 20% conclusion OVERALL MARK 5. Group work It is possible to work in groups of max. two students for this coursework. It is assumed that the work is divided equally between both partners in the group and that the work is produced in collaboration and joint working, rather than dividing up the tasks. Therefore, both students working in a team will obtain the same mark. If one student makes a disproportionate contribution, please discuss with the Module Leader ahead of submission. 2
