  • The Use of GIS and Remote Sensing for Environment Statistics Contents
    UNITED NATIONS STATISTICS DIVISION (UNSD) Workshop on Environment Statistics in support of the implementation of the Framework for the Development of Environment Statistics, Arusha, Tanzania, 6-10 July 2015 The use of GIS and remote sensing for environment statistics Contents • Temporal and spatial considerations • GIS data • Geospatial information • Data collections • Remote sensing • GIS Tools • Demos Temporal and spatial considerations • From FDES 2013 – Environment statistics require the simultaneous consideration of a number of temporal and spatial issues. – Important to align the temporal aggregations of environmental data with those used in economic and social statistics to ensure their proper integration, often a uniform calendar or fiscal year do not fit the diversity of natural phenomena; – therefore the use of different time scales, longer or shorter time periods is also necessary for the aggregation of environmental data over time. Spatial and Temporal • Spatial - Anything/event that occur in space has a spatial dimension – e.g environmental phenomena like air pollution, biodiversity conservation… • Temporal – anything/event relating to or limited by time, e.g disasters in 2014, hourly PM10 concentration at a specific site… Temporal and spatial considerations • For example, in fluid environmental phenomena, the temporal dimension is needed since there can be ebbs and flows, droughts and floods, snow and runoffs which all influence measurements. • Sometimes daily variations and at other times seasonal variations depending on what is being measured. Seasonal variations can be seen in the fluctuations in certain types of fish biomass, surface water levels, ice cap surface or the incidence of fires – monitoring focused more during some months • Temporal statistics often point out the maximum, the minimum and/or other ways of describing the relevant phenomenon and its levels below or above certain benchmarks, and are not restricted to a sum or an average over a longer period.

This unit may also be useful for SPTs at schools that already have computers and are thinking about buying more computer equipment or establishing additional computer labs. If your school already has a computer system and you are not considering expanding it at this time, you may wish to skip Unit 3 and jump to Unit 4. Why do we want to establish a computer effectively, you may want to stop the small system or lab at our school? group discussions and have each group This is an important question for the SPT briefly present the main points and answers to discuss and answer. At first, the answer to the questions its members have discussed. to this question may appear to be simple. Members of the SPT may answer, “Yes, we The questions that follow should help you should establish a computer system at our determine if your school should establish a school.” However, before you jump to this computer system or lab. Before starting the conclusion, it is important for you and the discussion, it would be helpful to present SPT to consider, discuss, and answer a few this list of questions to the SPT and ask if other related questions.

  • Technical Paper on Spatial Data Infrastructure Standards
    Integrated Spatial Planning Toolkit Module X: Technical Paper on Spatial Data Infrastructure Standards Draft October 28 2009 - for circulation and comment Prepared by: Dr Melissa Burgess Integrated Spatial Planning and Communications Specialist United Nations Development Programme Regional Center Bangkok Email: [email protected] Background: The United Nations Development Program - Regional Centre in Bangkok (UNDP-RCB) is managing a project funded by the Government of Japan titled “Better Informed Environmental Decision Making through Integrated Spatial Planning”, which is under implementation in the Asia-Pacific Region. A Toolkit designed to assist governments develop their capacity for Integrated Spatial Planning is being developed as part of this project. This document comprises the first draft of Module X of this Integrated Spatial Planning Toolkit, on Spatial Data Infrastructure Standards. Integrated Spatial Planning Toolkit Module X: Spatial Data Infrastructure Standards Page 1 Technical Paper on Spatial Data Introduction Spatial Data Infrastructure standards Spatial Data Infrastructure (SDI) comprise of those policies, organisational remits, data, technologies, standards, delivery mechanisms, and financial and human resources necessary to ensure that users of spatial data are supported in meeting their objectives by improving capacity for geographic information exchanges, harmonization and integration. SDI Standards describe objects, features and items that are collected, automated or affected by the activities or the functions of organisations. The development, publication and acceptance of data standards are important goals of an integrated information management solution. Such standards are essential for all users and producers of data and information. They are particularly important in any co-management, co-maintenance or partnership arrangements where data and information need to be shared or aggregated.
