Across
- 5. may include the physical characteristics of a place, such as boundaries of a neighborhood, or the attributes of a place, such as a neighborhood's perceived unsafe areas.
- 8. A device or system that detects surface features on the earth by bouncing radio waves off them and measuring the energy reflected back.
- 9. To test for, detect, and correct errors in a computer program or component.
- 11. A collection of states representing the changes that have occurred over time in a versioned geodatabase.
- 12. In geoprocessing, data put into the system for processing, usually specified by a path in a dialog box, script, or at the command line.
- 14. The height or vertical elevation of a point above a reference surface.
- 15. data Data classified relative to a fixed zero point on a linear scale. Mathematical operations can be used on these values with predictable and meaningful results.
- 17. A brass or bronze disk, set in a concrete base or similarly permanent structure, inscribed with a mark showing its elevation above or below an adopted vertical datum.
- 19. A diagram or abstract map in which geographical areas are distorted proportionally to the value of an attribute.
- 20. In a rectangular coordinate system, the distance of the x-coordinate along a horizontal axis from the vertical or y-axis.
- 24. The route of data passage through a system.
- 26. Half of a celestial body, such as the earth.
- 28. The name of the U.S. Department of Defense's Global Positioning System (GPS).
- 30. Reducing the number of points that define a line while preserving its essential shape.
Down
- 1. a geometric element from which paths are constructed. A segment consists of a start point, an endpoint, and a function that describes a straight line or curve between these two points.
- 2. In linear referencing, a series of vertical line or marker symbols displayed on top of features at an interval specified in route measure units.
- 3. A file, created by either a software user or an operating system, that holds temporary data or results during an operation.
- 4. Half of a celestial body, such as the earth.
- 6. One of a set of ordered x,y coordinate pairs that defines the shape of a line or polygon feature.
- 7. A set of data elements arranged in rows and columns. Each row represents a single record. Each column represents a field of the record.
- 9. One or more structured sets of persistent data, managed and stored as a unit and generally associated with software to update and query the data.
- 10. A database or file structure used primarily to store, query, and manipulate spatial data. Geodatabases store geometry, a spatial reference system, attributes, and behavioral rules for data. Various types of geographic datasets can be collected within a geodatabase, including feature classes, attribute tables, raster datasets, network datasets, topologies, and many others
- 13. an on-demand cache that contains levels of detail for areas that have been visited, or a pre-processed cache that has a specified, incomplete, level of detail range for the entire layer.
- 16. A spatial data model that defines space as an array of equally sized cells arranged in rows and columns, and composed of single or multiple bands.
- 18. In a rectangular coordinate system, any of the quarters formed by the central intersection of x and y axes that divide a plane into four equal parts.
- 21. A map depicting background reference information such as landforms, roads, landmarks, and political boundaries, onto which other thematic information is placed
- 22. A rectangular arrangement of data, usually numbers, in rows and columns. In computer science, a two-dimensional array
- 23. a network location used to represent a starting, stopping, or renewal location for routes in vehicle routing problem (VRP) analysis.
- 25. A coordinate-based data model that represents geographic features as points, lines, and polygons.
- 26. The study of water, its behavior, and its movements across and below the surface of the earth, and through the atmosphere.
- 27. An angle equal to 1/60 of a degree of latitude or longitude and containing sixty seconds.
- 29. A request to select features or records from a database
