2 GIS: a formal definition “A system for capturing, storing, checking, integrating, manipulating, analysing and displaying data which are spatially referenced to the Earth. This is normally considered to involve a spatially referenced computer database and appropriate applications software”Chorley Report, 1987“…a digital map, data located on the map, and a software application (GIS) that links the two together” Diana Freeman (2004)
3 What is Data? Location Data How Many? – What Kind? – Where? Scale of DataLocal to GlobalData PresentationWords, Charts, Graphs, Tables, or MapsEstimates are that 80% of all data has a spatial componentData from most sciences can be analyzed spatiallySlide from ESRI presentation for GIS DayIn the Dr. John Snow example, the locations of the water pumps, the cholera deaths, and the old cemetery are all spatial data. The spatial analysis that Dr. Snow performed was geographic information system (GIS) analysis without a computer. It took Dr. Snow a week to complete his analysis, by then hundreds had died and Soho was deserted; many of the people had fearfully fled. Today we can perform the same analysis in a few hours.3
4 “Imagination is more important than knowledge.” How can GIS aid teaching and learningGIS is a powerful and versatile tool for decision makersEnables core geographical issues to be investigatedProvides opportunity to explore spatial relationshipsImprove students’ graphical and statistical analysis skillsSupports development of a wide range of skillsIdeal resource for courseworkIncrease motivation and retentionImprove their enquiry skillsDevelop their mapping skillsAppreciate how people , places and environments change over a period of time.Experience alternative images of people., places and environments changeImprove the appearance of work“Imagination is more important than knowledge.”
5 GIS concepts are not new! London cholera epidemic 1854Cholera deathWater pumpSoho+In the London Cholera epidemic of 1854 Dr. John Snow was able to locate the source of the the outbreak by plotting the locations of fatal cases.
6 GIS is not just for Geography! Writing about personal experiences at different locations, scales or further a field in English e.g. What is it like looking down from space and what would you see as you travelled from one place to another?Comparing places in the past and present in History.Shape, Space, Measure, Trigonometry in Mathematics.Measuring Athletic events in Physical Education.Observing the Earth from Space in Science.Analysing voting trends in Politics.Carrying out surveys of local areas in CitizenshipSurveying of plant species in BiologyCreating Art using mapping software

15 GIS starting points on GA and RGS websites Geographical Association’s Spatially speaking project Geographical Association’s Think Pieces GIS project Geographical Association’s GIS starts here
16 Skills based development Curriculum based developmentHere you develop first the ideas of skills for example:Switching on/off layersBasic tools like zoom in/out, panUsing tools like swipe & transparencyAdding points, lines & polygonsViewing multiple layersSearching by attributesSelecting an area to search withinAdding your own data to geographically referenced locations(points, lines & polygons)Here you would focus on curriculum opportunities as dependant upon your programmes of studies for example based upon our 7 SoW:Map skillsMy placeConnectionsMicroclimateGlobal CitiesWhy did so many people die in the Haiti EQ?
17 ISSUES Get to grips with the basic language Start small Keep it simple Keep practisingTimeDon’t be afraid to ask for helpThink beyond geographyMake it real
