Document Summary
Data model it is a template for data. Spatial model they are the expressions of how the world is believed to work. Social processes : residential segregation, movement of cars. Digital or computational : computer operations, 0 s and 1s language, geocomputation. Spatial : variation in space, results of modelling change when object location change. Spatial shortest distance over which change is recorded. Spectral capacity to resolve spectral features and bands into separate components. Radiometric number of divisions of bit depth. Temporal shortest time over which change is recorded. In order to support a decision or process, to experiment on replica of world. To examine dynamic outcomes, analyzing statistical results, modelling. Static models represents single point in time, combines inputs into a single output. Aggregated and individual model human systems, physical systems. Cellular models raster approach, states, calibration and validations. Agent-based models for modelling individuals, macro pattern can emerge. Cartographic models local, focal, zonal, global.
