CSci 8715 :Spatial Databases Spatial Data Warehouses : A Survey Group 4: Nipun Garg Surabhi Mithal http://www-users.cs.umn.edu/~smithal/
Motivation Need For Spatial DW Research literature scattered. Need for effective consolidation Applications in Urban Planning, Retail, Logistics, Forecasting, Security etc.
Problem Statement • Objectives • Effective grouping of topics • Good Coverage of literature. • Identification of future research areas. • Challenges • Classification • Scattered information. • Difficult to consolidate. • Difficult to compare different approaches
