Frequently Asked Questions - CubeSTOR®
What is a Spatial Data Warehouse?
The concept of a Spatial Data Warehouse evolves from the same concepts and definition that are applied to business data warehousing:
A subject-oriented, integrated, time-variant, non-volatile collection of (geo)spatial data.
In essence, geospatial data that:
- Is composed of multiple (disparate) data sources and data products;
- Is optimized to support data production and data distribution requirements
- Is updated by operational systems.
A Spatial Data Warehouse is a multi-dimensional solution:
- It stores all types of GeoData (vector, matrix, raster, etc.) directly into the repository at different levels of resolution
- It allows end-users to query vast amounts (terabytes) of disparate GeoData with a very fast response time
- It allows for visual discovery (or navigation) of all GeoData relating to a subject, or spatial extent:
- End-users can "slice and dice" through different (and disparate) layers of GeoData
- End-users can drill down or roll up through various dimensions (resolutions) of GeoData
- End-users obtain a generalized or aggregated view of the GeoData

What is CubeSTOR®?
CubeSTOR is a highly scalable Spatial Data Warehouse solution that handles massive amounts of disparate geospatial data. Built within the Oracle engine, this product includes a spatial cartridge used to store, manage, access and publish geospatial data (vector, matrix and imagery) on the Internet.

Does CubeSTOR have any reprojection capabilities?
CubeSTOR allows users to specify a different reprojection when data is being ingested inside the warehouse. CubeSTOR directly supports over 1100 EPSG projections. In addition, users can create their own spatial reference system definitions.

How does CubeSTOR differ from ESRI ArcSDE™?
The two (2) major differences between CubeSTOR and ESRI ArcSDE are:
- CubeSTOR provides you full customization capabilities for the spatial data model used to create the spatial tables inside the warehouse
- Visual discovery of geospatial data stored inside CubeSTOR does not require any prior knowledge of the existence and/or location of a particular layer. This means that you don't need to create a project (map) to link/access/discover a layer. CubeSTOR support GeoData Browsing. White Paper on GeoData Browsing (PDF format)

Does CubeSTOR support color rasters, multi-layered rasters, lossless compression, lossy compression?
Yes to all of the above.

Does CubeSTOR support recreation of seamless orthomosaic when tiles are updated in the warehouse?
Yes. The aggregation process allows you to update individual tiles without having to reaggregate the entire content of the spatial data warehouse.
