Across
  1. 3. The vertical height of a location relative to a reference surface, commonly mean sea level.
  2. 5. A GIS operation that transfers attributes between features based on their geographic relationships.
  3. 9. A raster image file format that embeds geographic referencing information.
  4. 12. A raster operation that assigns new values or categories to existing cell values.
  5. 13. A geoprocessing operation that merges adjacent or overlapping features based on shared attributes or specified rules.
  6. 15. A GIS data storage structure that organizes spatial datasets, attributes, and relationships.
  7. 18. A digital representation of terrain elevations, commonly stored as a raster grid.
  8. 20. A remote sensing technology that uses laser pulses to measure distances and create detailed 3D representations of the Earth's surface.
  9. 21. A term describing information that is associated with a specific location on Earth's surface.
  10. 22. A vegetation index calculated from red and near-infrared reflectance to assess vegetation greenness.
  11. 23. A GIS operation that creates a zone at a specified distance around a geographic feature.
Down
  1. 1. Information describing a dataset's source, content, accuracy, coordinate system, and other characteristics.
  2. 2. A closed, two-dimensional vector feature used to represent areas such as parcels, lakes, or floodplains.
  3. 4. A reference framework used to define geographic coordinates and elevations on Earth.
  4. 6. A geoprocessing operation that identifies overlapping portions of multiple feature layers and combines their attributes.
  5. 7. A geoprocessing tool used to extract features or data within a defined boundary.
  6. 8. The process of calculating new raster cell values when changing a grid's resolution or alignment.
  7. 10. To correct an aerial or satellite image for terrain and sensor distortions so it aligns accurately with a map.
  8. 11. A mathematical method of representing Earth's curved surface on a flat map.
  9. 14. A popular programming language used to automate GIS workflows and perform spatial analysis.
  10. 16. The spatial rules and relationships that describe how geographic features connect, overlap, and share boundaries.
  11. 17. A widely used Esri vector data format consisting of several associated files that store feature geometries and attributes.
  12. 19. A popular free, open-source desktop geographic information system.
