Risk assessment (RA) means the determination of qualitative and quantitative value of risks, related to a certain situation and the recognized hazards. Risk assessment is a certain phase in a risk management process. Risk management (RM) focuses on identification of risk improvement strategies. RM uses information from the risk assessment to identify engineering, management and financial strategies to diminish those consequences. Risk assessment and risk management of climate change related risks to the urban water cycle areaddressed in WA 2 of the PREPARED project (PREPARED, 2009). RA and RM are the cross-cutting issues and will have an ongoing two-way interaction with the technology development for adaptation of drinking water supply and sanitation systems of cities in the other WAs. Taking into account that climate change affects the entire water cycle and all these processes have spatial distribution, GIS tools and applications will form the basis for DSS development and will be used in the monitoring systems for integrated water resources management. This report presents the information about GIS software and applications which may help to evaluate climate change impacts on drinking water supply and sewerage systems, to predict possible changes and be prepared for the consequences. The accent is on the products related to RA/RM for the urban water cycle hazards. The descriptions of these products in this report were based on available digital information (Web), a literature review and the answers to the questionnaire, received from the project partners (both research and utilities). The following key subjects were used for identification of GIS software listed in the review. The GIS applications can be directly used or adapted for RA/RM under regional circumstances of: o Drinking water supply o Sewerage networks o WWT o Risk management o Risk assessment o Climate Change o Urban water cycle Taking into account that in the project development and/or adaptation of Open Source software was planned, the difference between both open source and commercial categories of software is discussed. In addition, GIS is used to identify potential chemical and microbial contaminant sources by combining land use, industrial activity and location of drinking water abstraction points. The main goal of the (literature) study was to provide an overview of GIS applications that have been or can be used for RA/RM of climate change Overview of GIS applications - Prepared 2011.015 © PREPARED - 1 - 10 august 2011 hazards and to define missing GIS applications, which should be developed/adapted during the project. Each identified software category is described in the report with reference to the last available version (for Open Source products) or the web site of the developer (for commercial products). The descriptions of products do not reflect the opinion of the authors or the PREPARED project, as they were based on the (commercial) information of the developer. A first vision of missing (by opinion of partners’ organizations) software products, which should be developed/adapted in future for adaptation on climate change hazard events, is included in the summary of the report.

GIS software can be sorted into different categories. Below, there is a list of notable GIS software applications, characterised by two main groups: open source and commercial software (see table 1.1). Open-source software is computer software that is available in source code form for which the source code and certain other rights, normally reserved for copyright holders, are provided under a software license that permits users to study, change, and improve the software. Open source licenses often meet the requirements of the Open Source Definition. Some open source software is available within the public domain. Open source software is very often developed in a public, collaborative manner [2]. Free open source software is referred to as FOSS. Public domain software is software that has been placed in the public domain, in other words there is absolutely no ownership (such as copyright) of the intellectual property that the software represents. Commercial, off-the-shelf (COTS) or simply off the shelf (OTS) is a term defining technology which is ready-made and available for sale, lease, or license to the general public. Freeware (from "free" and "software") is computer software that is available for use at no cost or for an optional fee. Software referred to as freeware is almost always proprietary. Commercial software is occasionally referred to as payware. The principal difference is that free software can be used, studied, and modified without restriction; free software embodies the concept of freedom to use, while freeware is free-of-charge. Freeware is also different from shareware; the latter obliges the user to pay after some trial period or to gain additional functionality [1].

  • 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.

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.

When scientists are evaluated … their efforts in curating, managing and quality assurance of data sets that future generations of researchers can use are not taken into account … .” Dr J-B Minster, Chair: ICSU World Data Center System. Collecting and analysing spatial data during Disaster Risk Assessments is generally seen as a relatively easy one where data is collected and thereafter most of the actual project work revolves around the analysis of the data and modeling the risks… However, the time and effort that it takes to get the spatial data into a usable format and eventually give it back to the end-users in a way that they would be able to utilize it effectively in future exercises/projects, is generally underestimated… Spatial Data types Notable commercial or proprietary GIS software CAD / GIS (vector/raster): Autodesk – MapGuide and AutoCAD .

  • What Is Openjump
    http://tsusiatsoftware.net/jts/javadoc/index.html What is OpenJUMP Download OpenJUMP facts sheet "JUMP is a computer program that uses a unified mapping platform as a visualisation framework..." (changed ESRI keynote on What is GIS? by M. Bobzien) But to be a bit more serious - OpenJUMP is an open source GIS software written in Java and it is based on JUMP GIS by Vivid Solutions. Furthermore... It is a Vector GIS that can read rasters as well . OpenJUMP is known to work on Windows, Linux and Mac platforms, but should work on any operating system that runs Java 1.5 or later. It is not just another free demo viewer, but you can edit, save, analyze etc. with JUMP / OpenJUMP . It works, even with medium size datasets, and with professional touch . It provides a GIS API with a flexible plugin structure, so that new features are relatively easy to develope around the sound mapping platform. It utilizes OGC standards like SFS, GML, WMS and WFS . It is already translated in English, Finnish, French, German, Italian, Portugese and Spanish. The translation in other languages is in progress. ..and it is free (under the GPL license). OpenJUMP finally adds some key enhancements to the original JUMP software, including: . I18N (internationalization), . more drawing and geometry editing tools, . advanced attribute query, . enhanced set of selection tools, . image export in Scalable Vector Graphics (SVG) format, . function to copy objects including attributes, . it can show layers dependent on the current map scale, . more classification methods for thematic coloring . ... OpenJUMP is the result of a larger umbrella project called the JUMP Pilot Project (JPP).
