This is normally considered to involve a spatially referenced computer database and appropriate applications software” Chorley Report, 1987Slide5: GIS concepts are not new ! London cholera epidemic - 1854 +Slide6: GIS components Applications ? G I S Spatial data Computer hardware / software toolsSlide7: What makes data spatial ? Place name Postcode Distance & bearing DescriptionSlide8: Categories of spatial data Point GPS Street address Soil sample grid Line / Polyline AHS boundary Postcode boundary Road centreline Raster Aerial photograph Landsat-7 satellite imagery DEMSlide9: Resolution of spatial data Scale is important 1:100,000 means 1cm = 1 kilometre Spatial resolution refers to the relative accuracy or precision of spatial data E.g. Landsat-7 satellite images have 30 metre cellsSlide10: GIS Software MapInfo Professional (demo) Vertical Mapper ESRI ArcGIS Spatial Analyst Geostatistical Analyst Manifold GRASS Free open source PostGIS Free open sourceSlide11: Summary GIS handles SPATIAL information GIS is a valuable tool for managing and analysing environmental health datasets Don’t underestimate the time involved in obtaining data in the form you need Similar for learning how to use a GIS software package You do not have the permission to view this presentation.
