Chapter 6 Gis Pdf Geographic Information System Object Computer Ocg 311 gis technology chapter 3: gis data structure characteristics of gis data 1. location – (a) the spatial location of features are defined by coordinates in a specific reference system. (b) those features are represented by points, lines or polygons. (c) the geometry of the features refers to the three dimensional representation in space. 2. temporality – (a) the database model should. Gis data structures from the 2 d map to 1 d computer files representing geographic features: review from opening lecture how do we describe geographical features? by recognizing two types of data: spatial data which describes location (where) attribute data which specifies characteristics at that location (what, how much, and when).
