OTHER INFORMATION TO NOTE Page 20: There was an error with the pre-prepared project file “TewkesburyCaseStudy_Polygons.qgis” at this stage, which may have resulted in you getting an error when applying the code to update the postcodes. This has now been amended and if you wish to download the amended data, within folder ‘LandReg&CodePoint’, please do so here: http://ow.ly/X7iSG Page 21: Copy and paste the code to update the postcode from the text file “VoronoiPolygon_FieldCalculatorCode” supplied in the main folder and not the version in the pdf booklet as it won’t work. Other: The pdf version of the booklet within your folder may contain additional information that is not included in the printed version you were supplied with: • List of suggested resources for the links of where to find good sources of Open Data (page 33 of pdf booklet) • Additional tutorial on QGIS 3D Capability using OS Terrain 50 and other visualisations of water-related data in QGIS (page 31,32 of pdf booklet)
Editor's Notes
- The class is based around the 2007 Tewkesbury floods, demonstrating how to use OS OpenData to map flood risk areas, calculate housing cost damages and display the ability of Open sources in real life situations. It is designed to teach you about the various open products, what is available to you and how to use a free GIS system without needing any experience. The booklet provided along with the memory sticks have step by step instructions & images on exactly how to use the tools and data. It doesn’t matter if you are brand new to it or have years of GIS experience, there will be something new for everyone. Everything used in the class is open from the data to the tools used. OS, EA, DEFRA, Land Registry, BGS, Natural England all have a variety of open source products available for us to demonstrate.
- Loads of helpers, just raise your hand There are a range of QGIS project files that are available for various sections if you want to skip ahead at all. At various stages in the document, if you get stuck or simply skip to the next step there are shapefiles that can be loaded in. These have QMLs attached to them so are loaded already styled.
- You can choose to follow the class as much or as little as you wish. Feel free to go straight to the third party project folder, the 3D examples or even amalgamate your own data in with what is provided. Those helping you will have plenty of experience, so feel free to share your ideas if you want.
