13. FID feature identification code links the feature with it’s attributes Practice these vocabulary with Purpose Games “Price Ch1 Vectors” found here: http://www.purposegames.com/game/price-ch1-vectors-quiz/info

14. Georeferenced the information is tied to a specific location on the earth’s surface Practice these vocabulary with Purpose Games “Price Ch1 Vectors” found here: http://www.purposegames.com/game/price-ch1-vectors-quiz/info

16. Shapefile contain only one feature class, spatial data model developed for and used by ArcView3 and later versions Practice these vocabulary with Purpose Games “Price Ch1 Vectors” found here: http://www.purposegames.com/game/price-ch1-vectors-quiz/info

17. Spaghetti model a model which stores spatial features as a series of xy coordinates as independent objects unrelated to each other and does not store topological relationships between features Practice these vocabulary with Purpose Games “Price Ch1 Vectors” found here: http://www.purposegames.com/game/price-ch1-vectors-quiz/info

18. Thematic mapping displaying the features of a spatial data layer based on values in its attribute table Practice these vocabulary with Purpose Games “Price Ch1 Vectors” found here: http://www.purposegames.com/game/price-ch1-vectors-quiz/info

19. Topological model a data model which stores spatial relationships between features in addition to their xy coordinates Practice these vocabulary with Purpose Games “Price Ch1 Vectors” found here: http://www.purposegames.com/game/price-ch1-vectors-quiz/info

20. Two basic vector models topological models and spaghetti models Practice these vocabulary with Purpose Games “Price Ch1 Vectors” found here: http://www.purposegames.com/game/price-ch1-vectors-quiz/info

21. Vector model a spatial data storage method in which features are represented by one or more pairs of x,y coordinate values forming points, lines or polygons Practice these vocabulary with Purpose Games “Price Ch1 Vectors” found here: http://www.purposegames.com/game/price-ch1-vectors-quiz/info

22. Vertex/vertices intermediate points along the line Practice these vocabulary with Purpose Games “Price Ch1 Vectors” found here: http://www.purposegames.com/game/price-ch1-vectors-quiz/info

23. Raster model a spatial data storage method in which spatial data are represented by a series of small squares called cells or pixels Practice these vocabulary with Purpose Games “Price Ch1 Rasters” found here: http://www.purposegames.com/game/price-ch1-rasters-quiz/info

24. Two styles of raster storage continuous rasters discrete rasters Practice these vocabulary with Purpose Games “Price Ch1 Rasters” found here: http://www.purposegames.com/game/price-ch1-rasters-quiz/info

25. Continuous raster data that take on a variety of different values and that change rapidly across a data set (elevation, for example) Practice these vocabulary with Purpose Games “Price Ch1 Rasters” found here: http://www.purposegames.com/game/price-ch1-rasters-quiz/info

26. Discrete raster data which take on a relatively small number of distinct values Practice these vocabulary with Purpose Games “Price Ch1 Rasters” found here: http://www.purposegames.com/game/price-ch1-rasters-quiz/info

27. Each pixel has a numeric code indicating the land use, and the raster is stored as an array of numbers Practice these vocabulary with Purpose Games “Price Ch1 Rasters” found here: http://www.purposegames.com/game/price-ch1-rasters-quiz/info
