Document Summary
Week 3 lecture 1: introduction to gis in the context of natural hazards. Geotagging: mobile location devices allow receiving and broadcasting of location. Remote sensing satellite advancements in delivering high resolution imagery. Most data now have a geospatial tag . Internet speed, cloud computing and web 2. 0 (google earth) People as individual sensors (vgi: through the use of mobile phones (gps), smart watch and other devices geospatial datasets and information. Gis is concerned with the description, explanation and prediction of patterns and processes of geographic scales. Geographic information systems are computer- based spatial information systems for compiling, storing, manipulating, managing, processing and analysing geographic data, modelling spatially variable phenomena and disseminating primary or derived geospatial information. Integration of spatial data: management of spatial data, ~> storage, manipulation and analysis of spatial data, production and display of spatial data. Spatial data translates into simply objects: points, lines. Location of specific infrastructure: rivers, areas, grids.
