Collect earth & earth map

  1. 1. Collect Earth & Earth Map Land monitoring and analysis Alfonso Sanchez-Paus Land Monitoring Specialist Alfonso.SanchezPausDiaz@fao.org
  2. 2. Augmented Visual Interpretation • Data Collection tool integrated in Google Earth. Free access to Very High Resolution imagery. • Multitemporal imagery thanks to Google Earth, Bing Maps and High Resolution Imagery from Google Earth Engine. See video.
  3. 3. Geo-link between 3 data repositories
  4. 4. Access to 40 years of satellite data through Google Earth Engine Sentinel 2 &1 Landsat 5,7,8 MODIS Climate data
  5. 5. OpenForis.org Learn more about the rest of the software suite online FREE AND OPEN SOURCE
  6. 6. Collect Earth user cases Collect Earth facilitates the analysis of high and very high resolution satellite imagery for a wide variety of purposes, including : • Monitoring agricultural land and urban areas • Collection of spatially explicit socio-economic data (Vietnam) • Quantifying deforestation, reforestation and desertification (UN-REDD FREL ) • Support multi-phase National Forest Inventories • Land Use, Land Use Change and Forestry (LULUCF) assessments (18 partnering countries)
  7. 7. Data Analysis - Saiku • Fast, intuitive and flexible data analysis • Powerful tool for data quality control • Data export to Excel, CSV and PDF • Produce colorful and informative charts and graphs with a few clicks • Export graphics to JPG, PNG or other formats

  15. 15. Earth Map – new FAO Google Tool Google Earth Engine interface for simplified access to complex datasets Facilitated understanding of land cover/use dynamics processes for: ● Design and baseline assessment ● Monitoring during implementation ● Final evaluation Earth Map: new tool for quick historical environmental and climate analysis earthmapdemo.info
  16. 16. Code Editor full throttle and basic users Pros Full power to the user + Whole dataset access = Huge potential Cons Blinking-cursor syndrome Advanced skills requested Unfit for most non-expert users Also the Explorer may be too advanced in some context
  17. 17. Bare-bones interface, drop-down menus Pre-set functions and data for areas/tasks Google Infrastructure + FAO know-how High local knowledge, mixed skills AOI: pre-set or hand-drawn Visual output as images, charts or tables Trace anomalies and frequencies Gather quantifiable evidence Earth Map: facilitating, empowering, leveraging users
