Abstract
Canada, Mexico, and the United States Harmonize Their Small-Scale Frameworks
Track: Spatial Data Infrastructure
Author(s): Jay Donnelly
In 2004, the largest nations of North America collaboratively produced basic cartographic data layers at a scale of 1:10,000,000. These integrated data sets were documented in three languages; were made available online by each country for download at no cost to the end users; were provided as Web map services; and were published in a political base map of North America that was distributed to everyone who attended that year’s Esri International User Conference. These fundamental map layers became the geospatial framework for the North American Environmental Atlas. Federal mapping organizations in Canada, Mexico, and the United States have now agreed to produce an entirely new set of frameworks at a scale of 1:1,000,000. These data will be harmonized at national borders and will adhere to the Global Map data dictionary.
