Flashcards
Data Models & Planar Geometries
Cards in this deck (20)
- 1Spatial ModelBasic properties and process for a set of spatial features
- 2Cartographic ModelTemporally static, combined spatial datasets, operations
and functions for problem-solving - 3Spatio-temporal ModelsDynamics in space and time, time-driven processes
- 4Network ModelsModeling of resources (flow, accumulation) as limited to networks
- 5Data ModelsEntities and fields as conceptual models
- 6Static ModelingTaking inputs to transform them into outputs using sets of tools and functions
- 7Dynamic ModelingIterative, sets of initial conditions, apply transformations to obtain a series of predictions at time intervals
- 8VectorCoordinate based data model that represents points, lines, polygons
- 9RasterComposed of rectangular arrays of regularly spaced square grid cells and each cell has a value (attribute)
- 10PixelSmallest resolvable piece of scanned image - pixel is always a cell but a cell is not always a pixel
- 11GeodatabaseObject oriented spatial model (feature classes, feature datasets, non-spatial tables, topology, relationship classes, geometric networks
- 12Relationship ClassesModel real-world relationships that exist between objects such as parcels and buildings
- 13GridParallel and perpendicular lines for reference as a map projection or coordinate system
- 14TINTriangular Irregular Network
- 15Triangular Irregular Network (TIN)Portions vector data into contiguous, nonoverlapping triangles
- 16Advantages of TINSmall areas with high precision elevation data
- 17Disadvantage of TINRequires very accurate data source and costs are expensive, production and use are very computer intensive
- 18TopologicalFeatures need to be connected using specific rules
- 19HierarchicalDatabase that stores related information in a tree-like structure
- 20NetworkCollection of topologically connected network elements (edges, junctions, turns)
