1 Historical Assessment of Spatial Growth of Built-ups and Metropolitan areas of Delhi and Mumbai in India and Dhaka in Bangladesh Tomas Soukup, GISAT World Bank HQ, Washington DC Date : 12 April 2011

2 Introduction : The EO Service Provider GISAT company facts: - SME geoinformation company since located in Prague, Czech Republic - committed to remote sensing services - ISO quality certified Strong expertise in: - land monitoring - urban/spatial planning - environment - agriculture - emergency response & security Clients/customers: - National, European, Worldwide More to be found on

3 Background : The World Bank Project WB Task team Leader (TTL) : Mr. Songsu Choi, South Asia Region WB 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

4 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: ~15000km 2 - Temporal coverage: span of 20 years - Timeliness: Delhi Dhaka Mumbai 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

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: ~15000km 2 - 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

6 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

7 Examples of Previous Use Land Use Mapping Azerbaijan - Baku, Absheron User: World Bank / SCUPA Objectives: - production of up-to-date EO based land use information for large area (AOI ~ km²) - support creation of Greater Baku Regional Development Plan - Results: series of land use information, maps & statistics Copyright: M. Tomik, Service produced in the context of the GSE RESPOND project in EO data: HR/VHR imagery (SPOT5, ALOS & KOMPSAT) - Users feedback: your effort is very much appreciated by SCUPA management and they believe that these maps will be very useful for further actions in preparing of the GBRDP. Contact: Mr. Fuad Jafarli, SCUPA

8 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 compliance with the EEA integrated assessment framework - support of the EEA analytical & reporting obligations Copyright: M. Tomik, Results: statistics, graphs, change intensity maps and assessments for EEA38 countries - Service produced in the context of the EEA contract in 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.
