Introduction : The EO Service Provider
Background : The World Bank Project
WB Task team Leader (TTL) : Mr. Songsu Choi, South Asia RegionWB Team participants : Mr. Mats Andersson, Country Offices Project users : municipalities’ administration, WB activities TLs
- Project context :- Rapid urbanization & excessive slums expansion in South Asia- Delhi, Dhaka and Mumbai - megacities on top of the list - WB South Asia Megacities Improvement Program running
- Project Information requirements:- Key - a sequence of land use datasets monitoring urban growth- Additional - urban density mapping and road network mapping
- Reason / Driver for this information:- Sustainable urban management & planning - strategic policy priority - Better understand the spatial growth of built-up areas, its structure and
trends
The EO Information Products :What they are (1)
Time series of land use / land cover
- Standard product with flexible contents
- Thematic contents: 11 classes focused on urban (6 including density classes), agriculture, forest, water and other classes
- Spatial coverage: ~15000km2
- Temporal coverage: span of 20 years
- Timeliness:
Delhi 1992-2003-2011
Dhaka 1992-2002-2011
Mumbai 1991-2001-2011
- Resolution: 20m, minimal mapping area 1ha
- Validated product on Europe and Worldwide service cases
- EO data used: European HR missions archives - RapidEye and Spot1-5
The EO Information Products :What they are (2)
Land use / land cover changes Report with change statistics
- Standard product with flexible contents
- Thematic contents: 11x11 change classes; 8 change flows defined
- Spatial coverage: ~15000km2
- Temporal coverage: 3 periods in 20 years
- Resolution: 20m, minimal mapping area 1ha
- Statistics: consumption & formation share, balance; spatial distribution and intensity of changes; trends
- Validated product on Europe and Worldwide service cases
The EO Information Products :What they bring
Service benefits
- harmonised contents for large areas over long time
- information on spatial composition, quality and intensity of changes
- information comparable between megacities
Service advantages over existing solutions
- more time & cost efficient then on-site survey
- change detection (topomaps potential limited)
Limitations / Constraints
- EO data availability, quality and acquisition time
- availability of in-situ information
Positive impact on WB Project
- insight into urban related processes and drivers
- knowing the past / forecasting the future
- identification of priority areas
- more focused and efficient use of resources
Examples of Previous UseLand Use Mapping
Azerbaijan - Baku, Absheron
User: World Bank / SCUPA
Objectives:- production of up-to-date EO based land use
information for large area (AOI ~ 1.500 km²)- support creation of Greater Baku Regional
Development Plan
- Results: series of land use information, maps & statistics
- Service produced in the context of the GSE RESPOND project in 2008
- EO data: HR/VHR imagery (SPOT5, ALOS & KOMPSAT)
- Users feedback:“… your effort is very much appreciated by SCUPA management and theybelieve that these maps will be very useful for further actions in preparing of the GBRDP.”

Examples of Previous Use Change Analysis
Europe – Land Cover changes 2000/2006
User: European Environmental Agency (EEA)
Objectives:- production of countries & Europe analysis and
assessment based on CLC pan-European data 2006 - compliance with the EEA integrated assessment
framework- support of the EEA analytical & reporting obligations
- Results: statistics, graphs, change intensity maps and assessments for EEA38 countries
- Service produced in the context of the EEA contract in 2010
- Users feedback:Direct input into to the EEA Land Use Data Centre (LUDC), support of the ‘State and Outlook of Europe’s Environment‘ (SOER2010) and the ‘Europe’s Environment Assessment / Eureca2012‘ as well as other specific reports on land issues.
