GEOLAP Technology A geospatial-enabled decision support application framework for
• GIS technology is mainly based on transaction processing
• Strong need for analytical tools, processing complex queries of geodata
• Current GIS analytical technology does not exploit the strength of multidimensional data structures
• Geospatial information is not structured to be efficiently integrated into multidimensional data structures
• Restructuring geospatial data into multidimensional cubes is a time and resource intensive process, unlikely to happen without a paradigm shift
• This paradigm shift would enhance responsiveness (time), simplify complex queries, etc.
• Linking an intelligent cartographic context to OLAP represents an interesting short to mid term approach

GEOLAP TechnologyCharacteristics of the GEOLAP Technology
• The OLAP server is fetching contextual geodata to a GIS servers that renders this information based on the context of the OLAP analysis
• GIS servers are capable to render and symbolize, within seconds, complex geographical information
• The “geo” part of GEOLAP is generated on-the-fly. In consequence, the development cycle is reduced (no need to restructure the data) and applications can be rolled out faster

GEOLAP TechnologyCharacteristics of the GEOLAP Technology
• Symbolization of the information based on values of attributes generated from OLAP query
• Spatial filter that delimitates spatially the information to be analyzed
• Drill operations (down, across, up) among descriptive and geospatial data
• Short response time for complex queries associated to high volume of data
• Connectivity to OGC WMS server for map background generation (for the future, support of WFS, WCS, SVG standards is envisioned)
• Web-based architecture, 100 % HTML output

GEOLAP TechnologyGeneral Architecture of the Cartographic InventoryManagement and Analysis Application
– Metadata collected over the years by mapping agencies is mainly used for documenting and to support search capabilities for geodata, while it represents a much more important value
– Very few analysis are performed to analyze and manage data inventory due to the lack of proper tools
– Automatic representation of these analysis is usually unavailable and as such is done by hand and represents a long and labor-intensive process
– A better management of geodata inventory can be envisioned

GEOLAP TechnologyExample of an application
• The proposed solution
An application that links elegantly and efficiently,
analytical processes to a cartographic representation,
with decision-support tools
to empower a more adapted exploitation, analysis and management of geodata inventory

GEOLAP TechnologyExample of an application – context of the proposed solution
• Objective : empower a more adapted exploitation, analysis and management of geodata inventory
• To reach the objective, there is a need to
– Offer a complete inventory of data, up to date, and well documented with the proper metadata
– Offer fast and efficient tools to facilitate the discovery, access and exploitation of geospatial data
– Analyze the usage of the geodata to• Improve the overall quality of service to their users
• Improve the global process for managing the quality of their data
• Improve the global planning and decisional process for the improvement, update and production of geodata

GEOLAP TechnologyPresentation of the Cartographic Inventory Management and Analysis Application
• Web-based application thin client 100% HTML
• Multiple ways to present the information (map, chart, tables, lists)
• Link to the ordering system
• Link to the map and imagery visualization system (WMS server)
• Five modules targeted
– Inventory management and analysis (completed)
– Cartographic Development Indices management (completed)
– Production management and analysis (partially completed)
– Data diffusion management and analysis (planned)
– Quality control management and analysis (planned)

GEOLAP TechnologyConclusion
• Because
– this technology closely integrates GIS and BI technology
• It enables
– navigation in data as well as on a map, in a natural way by users, without special BI or GIS knowledge
– complex analysis on large amount of data without negative impact on operational system (e.g. slowdown or system crash)
– a whole new class of applications
• Now high level users (e.g. managers)
– are able to concentrate on business issues rather than fighting with a tool
