When you're in a decision making position it's important to have the right information sources available to you. This leads us to the fifth and final benefit of geospatial technology and in particular Geographic Information Systems (GIS):
Better Decision Making
Depending on your perspective there's always a best decision regarding a particular project or endeavour. Thats why the word 'best' is used. This may refer to meeting budget targets, locating infrastructure in the safest places or minimising the impact on surrounding people and areas.
For big and complex projects this is no simple task and it requires the input of numerous knowledge holders. GIS is a system for managing, visualising and analysing the geographic component of this information. It allows us to layer different types of information ontop of each other, to query it, to restyle it and to re-order it so that the best decision will be revealed to the user.
Of course using GIS is just one of many fall back options when in a decision making position. One can have unlimited meetings or leave the decisions to a vote whereby the responsibility for success can be shared. I'll let you judge the latter options however..
So if you do decide to use GIS to work with the locational aspect of your information then the likelihood of making the best decision is significantly higher. It'll allow you to feel more confident in your achievements and will lead to more moments of celebration.
