Gis 23 Lecture 3 Gis Data Representation Modeling Download Free The document summarizes the representation of geospatial data in a geographical information system (gis). it discusses the nature of geospatial data, types of attribute data, and gis data models. specifically, it describes the vector data model, which represents spatial features using points, lines, and polygons. points are represented by x y coordinates, lines by a series of coordinates, and. L155 gis data models and data processing lecture 3 dr. steve ramroop 3 this slide gives some general statements regarding spatial data structures and what makes spatial data different from non spatial data.
Gis Lecture 8 Cgcwc05 Pdf Geospatial data is numerical representation which analyses and describes real world features in gis. the nature of geospatial database is a dynamic rather than static and allows a range of functions such as organising, storing, processing, analysing and visualising spatial data. geospatial data depicts the real world in two basic models such as the object based model. Characteristics of spatial data types of spatial data this week, we will learn: concepts of database representation of diferent types of spatial data in gis commonly used spatial operators in gis. The document provides an overview of key concepts in geographic information systems (gis) including common data models. it discusses the two main data models raster and vector explaining their characteristics, advantages, and disadvantages.
