GEOGRAPHIC INTELLIGENCE v2.5<\/span><\/p>\n

Boundaries, Coordinates & Time<\/h1>\n

Coordinates state whether they are geographic centroids, administrative centroids, representative points, facilities or exact points. Boundaries are separately sourced and versioned.<\/p>\n

Preserve historical geography with historical data.<\/p><\/blockquote>\n<\/section>\n

PRINCIPLE<\/span><\/p>\n

A centroid is not a boundary, and a new boundary must not silently rewrite old data.<\/h2>\n<\/div>\n
