Geometric modelling is an important subtask of conceptual modelling and requires the following basics: - Overview of ISO 19107 - spatial schema - Overview of ISO 19125 - simple features - Examples of the usage of spatial schema and simple feature elements for feature class definitions - Relation to GML - Relation to DBs
This topic describes the process of Geometric modelling using vector data, means the primitives like points, lines, areas, bodies, or raster data. There is a strong relation to ISO standards (see relations) as they provide basic data types for geometric modelling. Main issues: - Geometric modeling based on vector data - Geometric modeling based on raster data - Conversion between the models - examples, advantages, disadvantages of the models
