DESCRIPTION
Presentation at workshop: Reducing the costs of GHG estimates in agriculture to inform low emissions development November 10-12, 2014 Sponsored by the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) and the Food and Agriculture Organization of the United Nations (FAO)TRANSCRIPT
Collect Earth
Multi-purpose land monitoring

What is Collect Earth?
A demo is worth a thousand words
• Free and Open Source tool ( downloadable from
www.openfori.org )
• Very High Resolution multi-temporal images from Google Earth and Bing Maps
• Landsat 7 and 8 datasets from Google Earth Engine
• Data Analysis through Saiku
History
• Open Foris Initiative
– Collect, Collect Mobile and Collect Earth
– Calc
– Geospatial Toolkit
• BMU-ICI Project ( Capacity Building for REDD+ NFMS )
– 18 Countries + more UN-REDD countries such as PNG and Mongolia
Use Cases
• Support multi-phase National Forest Inventories
• LULUCF assessments
• Monitoring agricultural land and urban areas
• Validation of existing maps
• Collection of spatially explicit socio-economic data
• Quantifying deforestation, reforestation and desertification

UNFCCC reporting
• Collection of activity data – Follow IPCC guidelines:
• IPCC Vol.4 Chapter 3 (Consistent Representation of Lands) : Approach 3 Spatially-Explicit Land-Use Conversion Data – Sampling approach (same as Annex II countries) – Land use, land use conversion (at least from 2000) and
Land Use Subdivision
– Data directly importable to GHG inventory tools (ALU Tool/IPCC software) • Integrating other data sources (Climate zone and soil
data)
Visual Interpretation applied to
Agriculture
• Plantations : e.g. Palm Oil plantations and Subsistence Agriculture in PNG.
> 27000 plots assessed -> data can be included
in GHG inventory
• Eurostat LUCAS
– N²O emissions for CAPRI
– Linear elements
Google Earth Engine
Support for NDVI, NDWI and EVI intra-year / inter-year analysis
Feature for crop identification

For Office Collect desktop is a flexible tool
for office or field camp based
inventory data entry.
Customizable validation rules
minimize data entry erros and
feedback reports help to identify
potential problems.
Sub headline
For Field Collect Mobile is an easy to use
Collect client for mobile Android
devices. Entering the data
already in the field can
significanlty improve the quality
of the data and reduce time
needed for data cleansing.
For Fast Delivery Colleyc Earth is an interative
image interpretation tool which
users Google Earth interface.
Collect Earth allows collection of
land cover and land use
information with the fastest
possible way and with minimum
GIS experience.

Easy Import Calc is a fully customizable tool for
facilitated data analysis. You can
import data directly from Collect,
import external equations and build
complex processing chains
Sub headline
For experts and end-
users Calc is designed for
both, experts and end users.
Whereas the experts can build
the processing chains, end
users can just hit play and
repreat the calculation
processes.
Reporting Calc results can be presented
using Saiku Analytics. This
allows easy reporting and
presenting the results in both,
tabular and graphical form.
