  1. Global Land Cover Network Workshop Bangkok December 1st 2003 Sub-regional Environmental Monitoring and Information System Phase II [SEMIS-II] Abhijit Patil UNEP RRC.AP, Bangkok

  2. Background • Following up from achievements of SEMIS I and recognizing the need for follow-up support; • SEMIS I achievements: Core datasets; conceptual database design; technical capacity for data exchange • Considering the request by Greater Mekong Sub-region (GMS-WGE-4) in Mar ’98, and endorsement by ministerial meeting in Sep’98, ADB approved SEMIS-II in Dec ’99 …to help GMS governments to make informed decisions regarding sustainable development through Integrated Economic and Environmental Development Planning

  3. Objectives • Assess the availability of useful and relevant data for planning purposes; • Increase andstrengthen the capacity of the national Governments to collect and process the information/data; • Increase the capacity of national Governments to make informed decisions regarding development investments relating to sustainable utilization of natural resources; • Enhance the ability of GMS national Governments to conduct integrated economic and environmental planning with relevant data; and • Conduct, store, manipulate, and share actual integrated planning information using the data collected in pilot projects for some “Hotspot” areas, such as those identified in TA 5783--REG: SEF-GMS.

  4. Work Program & Activities • Activities • Implementation plan • Position paper on data availability, quality, relevance, and data gaps • IEEDP planning concept/procedures, case study • Sub-regional inception workshop, National workshop to present and discuss data/info. gaps, and sharing mechanism • Assess capacity needs and develop capacity building plan • Data collection & mgmt. Guidelines. HW/SW support, Sub-regional training-cum-internship (GIS/RS) • GMS level land cover mapping (coarse and large res.) • Environment Atlas of GMS • National workshops to present findings, conclusions and follow-up actions to national line agencies (including planning/finance and environment agencies), Sub-regional seminar

  5. SEMIS II Outputs • Report on the availability, accessibility and usefulness of available data and data gaps • IEEDP concept paper/manual • Report on current status of data collection and processing facilities • Data collection and mgmt. Guidelines - translation • Capacity building • Training on GIS/RS applications in environmental management and planning • IEEDP procedures • HW/SW support • 6. Database generation • Land use/cover for whole GMS • Large scale (50K) data for HS areas • Case studies • Environment Atlas of GMS

  6. Major Output… Report on on data availability, accessibility and data gaps at sub-regional level • Available data and their relevance for planning purpose • Data gaps • Recommendations on • additional data requirements • Need of data standardization • (Working level scales, data exchange format, etc.) • National level mechanism for data generation/management

  7. Major Output… Guidelines and manual on geo-spatial data collection and management & translations • Contents • Review - regional data availability, accessibility and standards • Basic concepts – spatial data, measurement levels, data models, scale and resolution, precision and accuracy, projection systems • Guidelines – database design & mgmt., acquisition, quality, metadata, update/maintain and archival

  8. Activities on the DATA Specific Outputs: Data layers • Review available data and data gaps • Acquire the new data • Fill up the data gaps with the cooperation of concerned agencies • Guideline for data collecting/Mgnt • Training and Internship for technology transfer • Enhanced with HW/SW support • Case Studies by national agencies

  9. Present status on data • New series of Satellite data over the whole GMS area has been acquired • Landsat 7 ETM+ • NOAA AVHRR • GIS layers have been collected • New land cover data sets at 1:1M scale for GMS • New land cover data sets at 1:50K scale for Hotspot • Data collection Guideline in national languages

  10. Core Datasets

  11. Core Datasets (Cont;)

  12. Early Warning Information Systems (EWIS) It is product of the SEMIS I project, which involves a fairly complete database of important GIS layers like Environment (Forest, Rivers, Wetlands etc.) Demographic data (Population, Poverty etc.) Infrastructure (Road, Dams etc.) and some other ancillary information (layers) The data is provided in different scales (1:1M, 1:5M and 1:250K) depending on the layer and the source. The data was generated by UNEP RRC.AP along with the help of MRC, WWF and other international agencies. The national agencies were the major source for the local data layers.

  13. Additional Data • The additional to the core data layers followings are identified • Hydrological layers “part of topography, important for planning, normally use independently, should be collected”, (Topo and Hydro data layers can be derived independently using modern technology) • Digital imagery “digitized air photos, digital orthoimagery, satellite imagery etc.” (Landsat 7ETM+ is one of the solutions) • Scanned paper map “Reproduce the map, head-up digitizing, easy to georeferenced” (original maps can be scanned and save as raster format and use for multi purposes)

  14. Additional Data • The additional to the core data layers… (cont;) • Slope and aspect data layers “critical to some applications such as erosion, Crop selection etc.”, (not difficult to generate from elevation data, but useful for those who can not do for themselves) • Water Quality Data “.pH, conductivity, chemical analysis are proposed to be measured” (depth to groundwater, surface water hydrology, basin delineation, subsurface flow etc are useful for analysis of the impact of the potential projects)

  15. Major Output: GIS Layers GIS datasets for GMS • GMS level dataset • National level • Thailand • Vietnam • Yunnan • Myanmar • Cambodia & Lao PDR
