1. Spatial Information Retrieval

2. Spatial Data Mining + Knowledge Discovery Used for mining data in spatial databases with huge amounts of data Spatial data is defined as location-related data in an object A spatial database stores spatial objects and spatial relationships between these objects Important application - GIS

3. What is GIS Geographic Information System A computer-based system for storing, analyzing, and reporting map and spatial database, providing environmental, social economic and geographic information. A computer-assisted information system to collect, store, manipulate and display spatial within the context of an organization, with the purpose of functioning as a decision support system

4. What is GIS Layers or Themes: Objects that contain spatial information are represented as several different layers where each layer holds data about a particular kind of feature. Each feature is linked to a position on the graphical image on a map and a record in an attribute table.
