Across
- 3. The smallest individual unit of a raster image. Each _____ holds a value that represents a specific attribute of the area it covers.
- 4. Data: A type of qualitative data that categorizes information without a natural order or rank. Examples include country names or land cover types.
- 10. Unit: A spatial unit used for data collection, storage, and presentation. Common examples include census tracts, counties, or zip code areas.
- 11. A data model that represents geographic data as a grid of cells or pixels. Each pixel has a value representing a specific attribute, such as elevation, temperature, or land cover. This type of data is well-suited for continuous phenomena like imagery and elevation models.
- 12. Map: A map that focuses on a specific theme or subject, such as population density, climate, or income levels.
- 13. Line: A line that encloses the map's content. It helps to define the overall map area and separate it from marginal information.
- 14. The heading of the map, which provides a concise description of its content, purpose, and sometimes location.
- 16. Additional text below the title that provides more specific information about the map's content (often the location but with smaller font that the heading of the map).
- 17. A smaller map within a larger map that shows a specific area in greater detail or a remote location relative to the main map.
- 19. Autocorrelation: The principle that objects or attributes closer to each other in space are more related than objects farther apart.
- 20. A key that explains the symbols, colors, and patterns used on a map. It is essential for interpreting the map's features.
- 21. Line: The outermost line that delineates the map's entire content, including the map body, legend, title, and other elements.
Down
- 1. A data model that represents geographic features as points, lines, and polygons. This type of data is ideal for discrete features like roads, rivers, and property boundaries.
- 2. Data: Data that describes qualities or characteristics that cannot be measured numerically, such as land use type or vegetation class. It is often represented by distinct different colors or patterns on a map.
- 5. A cartographic element, usually a north arrow or graticules, that helps a user orient the map.
- 6. Class: A homogeneous collection of common features, each having the same spatial representation (point, line, or polygon) and set of attributes. It is a fundamental data structure within a geodatabase.
- 7. Data: A type of data that categorizes information with a specific, meaningful order or rank. Examples include levels of pollution (low, medium, high) or highway classifications (interstate, state route).
- 8. A container used to store, manage, and query geographic datasets. It can hold a variety of data types, including feature classes, raster datasets, and tables.
- 9. Resolution: The ground area represented by a single cell in a raster image.
- 15. Mapping Unit: The smallest size of a feature that is important enough to be distinguished in a particular feature class. Any feature smaller than the ________ mapping unit may be excluded or merged with larger features.
- 16. The ratio or relationship between a distance or area on a map and the corresponding distance or area on the ground. It can be expressed as a representative fraction (e.g., 1:24,000) or a graphic.
- 18. A non-topological, vector-based data storage format for storing the location, shape, and attributes of geographic features. It is one of the most common file formats for geospatial data.
