Geographic / Geospatial Statistics

The spatial context of information is critical when it comes to data – where something occurs is often now recognized to be just as important as what is actually occurring.

Geography Standards

Cartographic Standards

Wherever possible, OSI geographies and symbologies default to the mapping standards as commonly defined within the National Topographic System (NTS) Polychrome Map Standards and Specifications. To expand on these standards, where applicable, proprietary standards have also been defined following conventional and sound cartographic principles.

Metadata Standards

Metadata is kept and recorded for every spatial dataset used by OSI. All metadata is compliant with the Government of Alberta’s (GOA) standard of the ISO 19115 North American Profile. See more information on this standard.

Quality Control Standards

Every spatial deliverable in OSI undergoes a thorough Quality Control (QC) review to ensure accuracy and consistency throughout. This simple yet proprietary QC review process is rigorously enforced within OSI.
