Case Studies in Validating Maps: Oil Palm and Land Cover

Chris and Krishna talk about validation as a practical part of developing geospatial analytics, focussing on their personal experiences mapping oil palm and land cover at scale.

A central theme in throughout this conversation is the use auxiliary geospatial products, science and human intuition to validate maps.

(00:00) Introduction, what is validation?

(02:30) Chris talks about mapping oil palm using Sentinel-1

(25:00) Krishna talks about global land cover mapping using Sentinel-2

(51:00) What tools do Krishna and Chris use for validation. (Krishna loves QGIS)
