Description
Three national delimitation processes for páramos in Colombia, from 2007 to 2018, comparing spatial extents across scales of 1:250,000, 1:100,000, and 1:25,000. The dataset, created by Alejandra Uribe-Albornoz, contains geospatial layers showing gain and loss areas between transitions. It was derived from official government open-data and last updated in May 2026.
Use Cases
Analyzing changes in páramo ecosystem boundaries based on multi-year national delimitations.
Comparing mapping precision and its impact on area calculations based on the described scale transitions (1:250k to 1:100k to 1:25k).
Validating spatial analysis methodologies for environmental monitoring based on the described erase and symmetric difference tools.
Strengths
Compares three distinct national delimitation efforts from 2007, 2012, and 2013-2018.
Includes analysis at multiple mapping scales, with some areas delineated at a detailed 1:25,000 scale.
Derived from official Colombian government open-data sources.
