Complexities in Land Cover Validation: Updates, Protocols, and New Requirements

This report discusses the evolving complexities in land cover validation since 2006, including the need to update validation standards due to new sensors, varying reference documents, and high-resolution data. It also explores ongoing efforts and proposed initiatives in the JECAM community, GEOGLAM, and GFOI to generalize essential agriculture variables and develop modules for SilvaCarbon partner countries.

  2. LC validation protocol • Official CEOS-LPV procolfrom 2006 • Since 2006, things have become more complex • Much more capacity for LC maps production & new single-class production GlobeLand30 (Chen et al., 2015)

  3. LC validation protocol • Official CEOS-LPV procolfrom 2006 • Since 2006, things have become more complex • Much more sources of « reference data » • From CEOS test-site concept to Google Earth BOSTON University http://www.geo-wiki.org/ GlobCover – CCI projects http://glcval.geo-compass.com/

  4. LC validation protocol • Official CEOS-LPV procolfrom 2006 • Since 2006, things have become more complex • New varyingreference documents

  5. LC validation protocol • Official CEOS-LPV procolfrom 2006 • Since 2006, things have become more complex • New sensors and CEOS requirements • High resolution • LC change • Land Use => Need to update the validation standards

  6. LC validation protocol • Startedwithcropland validation (one-class product)Ongoing effort in the JECAM communityGEOGLAM planning to propose Essential Agriculture Variables (EAV’s) • To begeneralized to general LC products • GFOI Method and Guidance Documents: • Modules being developed in response to needs of SilvaCarbon partner countries • Extensive use in REDD+ countries • Continuous action • Pragmatic question: how to start?

  7. Other actions • Website update (review of LC products) • Newsletter to beissued • Organization of LC validation workshop?
