Geospatial, i.e. Geographic, modelling is about creating a map inside a computer with specific geographic locations, districts, areas etc. It might also contain statistics, like the number of people that live in each district.
On top of this model we then run software tools that can produce different ‘what-if’ analysis on the data. Something simple might be to find out how many people live within 20 Kms of some specific location.
More complex questions might be to find the right combination of locations to cover the whole population within 1 hour drive time or altering the type of service centre based on the level of demand.
How Can Geospatial Modelling Help You?
The main areas where geographic modelling is used are service provision and route planning. Service provision is about providing a service to a geographic area within some constraint, such as travel time. Examples are:
- Where are the best places to locate clinics to provide easy access for patients?
- What are the likely change in demand which some rearrangement of service centres?
- How many logistic centres are needed to cover a given area within a pre-set drive time
