  1. 3. A GIS operation to extract data within a specific boundary
  2. 5. A type of spatial data represented by grid cells (e.g., satellite images)
  3. 8. A type of spatial data represented by points, lines, and polygons (e.g., city boundaries, road networks)
  4. 9. Converting addresses into geographic coordinates
  5. 10. A systematic presentation of intersecting coordinate lines on a flat surface upon which features from a curved surface (as of the earth or the celestial sphere) may be mapped
  6. 12. The ratio of distance on the map to actual distance on the ground
  7. 14. A representation usually on a flat surface of the whole or a part of an area
  8. 15. The level of detail in spatial data, especially in raster images
  9. 16. The closeness of GIS data to the actual location or value
  10. 18. The study of spatial relationships between features in a dataset
  11. 20. A science that deals with the description, distribution, and interaction of the diverse physical, biological, and cultural features of the earth's surface
  12. 21. Information that describes data, such as its source or creation date
  13. 23. A popular file format used in GIS to store geometric location and associated data
  14. 25. The details that describe the properties and characteristics of spatial features. They can be of different types, including categorical (e.g., land use type), numerical (e.g., population), or binary (e.g., presence or absence of a certain characteristic).

  1. 1. The visual representation of a geographic dataset in any digital map environment. A slice or stratum of the geographic reality in a particular area, more or less equivalent to a legend item on a paper map (e.g., roads, rivers).
  2. 2. Combining two or more layers to analyze their relationships
  3. 4. A key explaining symbols and colors on a map
  4. 6. The visual representation of data on a map (e.g., colors, lines, icons)
  5. 7. Estimating unknown values within a dataset based on known data points
  6. 11. A zone created around a feature on a map (e.g., an area within 5 km of a river)
  7. 12. Relating to, occupying, or having the character of space or location
  8. 13. A request to extract specific data from a dataset
  9. 17. Any of a set of numbers used in specifying the location of a point on a line, on a surface, or in space
  10. 19. The level of detail at which data is measured or reported
  11. 22. A reference point or system used in mapping coordinates
  12. 24. Factual information (such as measurements or statistics) used as a basis for reasoning, discussion, or calculation
