Geospatial Analysis Tools and Applications for the Water Industry Ilona Kemeling WSUG 16th May 2012

Geospatial Analysis Content Geo-Statistical Analysis in ArcGIS Asset data is already stored in a geographical information system Geospatial Analysis Software Assets interact with local geography Geospatial analysis is used to visualise trends Geo-Statistical Analysis in ArcGIS GIS designed for data management but available for analysis

Assets interact with local geography Sewer blockages vary depending on number of connected users, type of users and presence of tree roots. CSO spills are more frequent in areas with more impermeable surface. Overland flooding can either be harmless or lead to a costly pollution incidence, depending on the landscape around a manhole.

Asset data is already stored in a geographical information system Statistics requires a database GIS provides a database but also provides geospatial information – location and shape This extends the range of statistical analysis that can be carried out

GIS designed for data management but available for analysis Water companies use various large-scale systems Integrating CAD and asset management Access through network Mobile access Analysis Tend to use Desktop applications Access to live GIS or local download Also purpose-specific software that uses GIS components (e.g. InfoNet, modelling software)
