Spatial Analytics and Mapping (10)
Spatial analytics provide powerful tools to model and analyse spatial data enabling relationships and trends to be identified that would not otherwise be apparent. Spatial analytics help organisations exploit the power of GIS for applications such as determining land-use suitability, preparing cost-benefit analysis, optimising resource allocation or targeting specific user groups or customers.
Fascinating but worrying to see the work reported in The Age Newspaper ("Great Ocean Road at risk from surging sea” 11/01/2019 – Royce Millar) concerning the impact of rising sea levels on the iconic Great Ocean Road along the south-western Victorian coastline. The article indicates that there are great concerns of continued sea level rise and erosion impacts washing away major sections of the Great Ocean Road in and around the Apollo Bay region.
Recently, a client commissioned us to map a web map of Australia to distribute in China. Specifically, the use case called for a web map of Australia with Chinese language labels, so that Chinese native-speakers could easily interact with the map of Australia in their own language. Both states and capital cities needed labels, and of course the more readable the cartography underneath – the better.
When we come to depict any spatial data in GIS, from physical assets and locations to real-world events and trends, there are two differing systems to display data; Raster and Vector representations. Both of these methods present data in their own format, with their own advantages and disadvantages.
Call triple zero; you expect the ambulance to get there promptly. Move into a new house; you expect to be able to get connected to gas and electricity etc. Many vital life transactions depend on reliable geospatial data for property addresses. In Victoria, the custodian for provision of most address data is your local government.
Many local councils currently face challenges maintaining this and other geospatial data, often due to easily preventable organisational issues. A key flaw with many councils’ is the lack of appreciation of the importance of geospatial data among the organisation’s upper tiers.
If you are into mapping emergencies, you will be interested to know that the Canadians have developed a national approach to Emergency Management Symbology (EMS)*.
The EMS is designed to be used by individual and multi-agency emergency mapping applications to facilitate interoperability and situational awareness.
Successful emergency response often starts with a map. The question of “where” is fundamental to instigating an effective response to an incident, the deployment of resources, the assessment of risks and the safety of the community. The symbols used to represent the location and type of incident or resources are critical to communication. The more recognizable the symbol, the faster its interpretation and the ability to make decisions based on it. Critically, there may be dire consequences if symbols are misinterpreted.
