Geostatistical tools to map the interaction between development aid and indices of need

  
No. 49. (2018)

Abstract

In order to meet and assess progress towards global sustainable development goals (SDGs), an improved understanding of geographic variation in population wellbeing indicators such as health status, wealth and access to resources is crucial, as the equitable and efficient allocation of international aid relies on knowing where funds are needed most. Unfortunately, in many low-income countries, detailed, reliable and timely information on the spatial distribution and characteristics of intended aid recipients are rarely available. Furthermore, lack of information on the past ...

 

First- and second-order conservative remapping schemes for grids in spherical coordinates

  
Monthly Weather Review In Monthly Weather Review, Vol. 127, No. 9. (1 September 1999), pp. 2204-2210, https://doi.org/10.1175/1520-0493(1999)127<2204:fasocr>2.0.co;2

Abstract

Coupling atmosphere, ocean, sea ice, and land surface models requires a means for remapping fields between grids in an accurate and conservative manner. A method is described here for computing interpolation weights for first- and second-order conservative remappings. The method is completely general and can be used for any grid on a sphere. ...

 

Mapping the interaction between development aid and stunting in Nigeria

  
In 28th IUSSP International Population Conference (2017)

Abstract

For meeting sustainable development goals (SDGs) an improved understanding of geographic differences in health status, wealth and access to resources is crucial. The equitable and effcient allocation of international aid relies on knowing where funds are needed most. For instance, aid for poverty alleviation or financial access improvement requires knowledge of where the poor are. Unfortunately, detailed, reliable and timely information on the spatial distribution and characteristics of intended aid recipients in many low income countries are rarely available. This lack ...

Creating spatial interpolation surfaces with DHS data

  
No. 11. (2015)

Abstract

Improved understanding of sub-national geographic variation and inequity in demographic and health indicators is increasingly recognized as central to meeting development goals. Data from DHS surveys are critical to monitoring progress in these indicators but are generally not used to support sub-national evaluation below the first-level administrative unit. This study explored the potential of geostatistical approaches for the production of interpolated surfaces from GPS cluster located survey data, and for the prediction of gridded surfaces at 5×5km resolution. The impact of DHS cluster displacement on these interpolated ...

Abstract

Forests cover over a third of the total land area of Europe. In recent years, large forest fires have repeatedly affected Europe, in particular the Mediterranean countries. Fire danger is influenced by weather in the short term, and by climate when considering longer time intervals. In this work, the emphasis is on the direct influence on fire danger of weather and climate. [\n] For climate analysis at the continental scale, a daily high-emission scenario (RCP 8.5) was considered up to the end ...

Integrating geospatial information into fire risk assessment

  
International Journal of Wildland Fire, Vol. 23, No. 5. (2014), 606, https://doi.org/10.1071/wf12052

Abstract

Fire risk assessment should take into account the most relevant components associated to fire occurrence. To estimate when and where the fire will produce undesired effects, we need to model both (a) fire ignition and propagation potential and (b) fire vulnerability. Following these ideas, a comprehensive fire risk assessment system is proposed in this paper, which makes extensive use of geographic information technologies to offer a spatially explicit evaluation of fire risk conditions. The paper first describes the conceptual model, then ...

Predicting plant species richness in a managed forest

  
Forest Ecology and Management, Vol. 180, No. 1-3. (July 2003), pp. 583-593, https://doi.org/10.1016/s0378-1127(02)00646-1

Abstract

This paper describes an attempt to predict ground flora species richness under various forest management scenarios. The approach is based on a geographic information system (GIS) and uses three standard map layers of topography, soils and stands to derive environmental gradients of light, nutrients, water and disturbance. A simple floristic survey provides the data necessary to relate plant distribution with environmental variables. The potential distribution of 60 understorey plant species is modelled based on the four derived gradients. The sum of ...

Topographic position and landforms analysis

  
In ESRI International User Conference (2001)

Abstract

[Excerpt: Introduction] Many physical and biological processes acting on the landscape are highly correlated with topographic position: a hilltop, valley bottom, exposed ridge, flat plain, upper or lower slope, and so on. Examples of these processes include soil erosion and deposition; hydrological balance and response; wind exposure; and cold air drainage. These biophysical attributes in turn are key predictors of habitat suitability, community composition, and species distribution and abundance. This poster presents an algorithm, implemented in GRID, for generating a multi-scale Topographic Position Index, classifying this index into slope position and ...

The integration of land change modeling framework FUTURES into GRASS GIS 7

  
In Free and Open Source Software for Geospatial - Open innovation for Europe, Vol. 12 (2015), pp. 21-24

Abstract

Many valuable models and tools developed by scientists are often inaccessible to their potential users because of non-existent sharing infrastructure or lack of documentation. Case in point is the FUTure Urban-Regional Environment Simulation (FUTURES), a patch-based land change model for generating scenario-based regional forecasts of urban growth pattern. Despite a high- impact publication, few scientists, planners, or policy makers have adopted FUTURES due to complexity in use and lack of direct access. We seek to address these issues by integrating FUTURES into GRASS GIS, a free and open source ...

Abstract

In addition to their importance to human and animal health, vector-borne diseases are fascinating systems to study. The involvement of multiple species whose biologies and life cycles cover differing space and time scales makes it extremely difficult to predict epidemics. A single environmental factor may have opposite impacts on the system at different points in time. Patchiness at different geographical scales may have very different causes, so it is important to identify the proper scale for a particular study. New developments ...

IEEE Earthzine, Vol. 7, No. 2. (2014), 877975, https://doi.org/10.1101/009589

Abstract

Bioclimate-driven regression analysis is a widely used approach for modelling ecological niches and zonation. Although the bioclimatic complexity of the European continent is high, a particular combination of 12 climatic and topographic covariates was recently found able to reliably reproduce the ecological zoning of the Food and Agriculture Organization of the United Nations (FAO) for forest resources assessment at pan-European scale, generating the first fuzzy similarity map of FAO ecozones in Europe. The reproducible procedure followed to derive this collection of ...

Remote Sensing Based Post-Disaster Damage Mapping – Ready for a Collaborative Approach?

  
IEEE Earthzine, Vol. 4, No. 1. (2011), 290822

Abstract

[Excerpt] Rapid and accurate assessment of structural damage is essential after disaster events, especially in densely built-up urban areas. The results provide guidance for rescue forces and other immediate relief efforts, as well as subsequent rehabilitation and reconstruction. Especially for spatially extensive events, ground-based mapping is too slow, typically hindered by disaster-related site access difficulties, or too dangerous as in the case of potential radioactive contamination resulting from the March 2011 earthquake and tsunami disaster in Japan. Remote sensing has long ...

 

Remote Sensing and GIS for Natural Hazards Assessment and Disaster Risk Management

  
In Remote Sensing and GIScience in Geomorphology, Vol. 3 (2013), pp. 259-298, https://doi.org/10.1016/b978-0-12-374739-6.00051-8

Abstract

The world has experienced an increasing impact of disasters in the past decades. Many regions are exposed to natural hazards, each with unique characteristics. The main causes for this increase can be attributed to a higher frequency of extreme hydro-meteorological events, most probably related to climate change and an increase in a vulnerable population. To reduce disaster losses, more efforts should be applied toward disaster-risk management, with a focus on hazard assessment, elements-at-risk mapping, and vulnerability and risk assessment, all of ...

If you want to explore the complete range of PostGIS techniques and expose the related extensions, this book is a must-have. This book is a deep-dive into the full range of PostGIS topics, with practical applications of the concepts ...

 

Geospatial tools address emerging issues in spatial ecology: a review and commentary on the Special Issue

  
International Journal of Geographical Information Science, Vol. 25, No. 3. (1 March 2011), pp. 337-365, https://doi.org/10.1080/13658816.2011.554296

Abstract

Spatial ecology focuses on the role of space and time in ecological processes and events from a local to a global scale and is particularly relevant in developing environmental policy and (mandated) monitoring goals. In other words, spatial ecology is where geography and ecology intersect, and high-quality geospatial data and analysis tools are required to address emerging issues in spatial ecology. In this commentary and review for the International Journal of GIS Special Issue on Spatial Ecology, we highlight selected current ...

 

Environmental Modeling Using Open Source Tools

  
Encyclopedia of GIS In Encyclopedia of GIS (2008), pp. 275-279, https://doi.org/10.1007/978-0-387-35973-1_355

Abstract

[Definition] Geospatial data can include socioeconomic, environmental, geophysical, and technical data about the Earth and societal infrastructure and hence is pivotal in environmental modeling and management (EMM). Desktop, web-based, and embedded geospatial systems have become an essential part of EMM, providing pre- or post-processing of geospatial data, analysis and visualization of results using a graphical user interface (GUI). When combined with the growing culture of free and open source software (FOSS), this combination of geographic information systems) GIS and environmental modeling ...

 

Bioclimatic and physical characterization of the world’s islands

  
Proceedings of the National Academy of Sciences, Vol. 110, No. 38. (17 September 2013), pp. 15307-15312, https://doi.org/10.1073/pnas.1306309110

Abstract

The Earth’s islands harbor a distinct, yet highly threatened, biological and cultural diversity that has been shaped by geographic isolation and unique environments. Island systems are key natural laboratories for testing theory in ecology and evolution. However, despite their potential usefulness for research, a quantitative description of island environments and an environmental classification are still lacking. Here, we prepare a standardized dataset and perform a comprehensive global environmental characterization for 17,883 of the world’s marine islands >1 km2 (∼98% of total ...

Geospatial and visual modeling for exploring sediment source areas across the Sele River landscape, Italy

  
Italian Journal of Agronomy, Vol. 6, No. 2. (13 April 2011), https://doi.org/10.4081/ija.2011.e14

Abstract

This study uses the revised universal soil loss equation (RUSLE) and Geographic Information System technology to map erosion-prone areas in the Sele basin (Campania-Basilicata regions, southern Italy). Current land use/cover, soil erodibility and climate factors were evaluated to determine their effects on average annual soil loss. Geospatial technologies were applied to generate RUSLE factors and erosion map. Long-term soil losses were 53 Mg ha–1 per year averaged over an area of 2500 km2 and more than 30% of the Sele basin ...

The European Forest Fire Information System (EFFIS) has been established by the Joint Research Centre (JRC) and the Directorate General for Environment (DG ENV) of the European Commission (EC) in close collaboration with the Member States and neighbour countries. EFFIS is intended as complementary system to national and regional systems in the countries, providing harmonised information required for international collaboration on forest fire prevention and fighting and in cases of trans-boundary fire events. However, one missing component in the system is ...

 

Web services for forest data, analysis and monitoring: developments from EuroGEOSS

  
IEEE Earthzine, Vol. 5, No. 2. (2012), 389531

Abstract

[Introduction] Forests play a crucial role in timber production, maintenance and development of biodiversity and in carbon sequestration and storage. However, the reliable information on forest extent, type and change, which is so important to policy makers and managers, is frequently inconsistent, incomplete and out of sync between countries and continents. In this article, we describe components developed in line with the GEOSS and INSPIRE frameworks, which access and use distributed forest information at different spatial scales, and demonstrate how these ...

 

Local Indicators of Spatial Association—LISA

  
Geographical Analysis, Vol. 27, No. 2. (1 September 1995), pp. 93-115, https://doi.org/10.1111/j.1538-4632.1995.tb00338.x

Abstract

The capabilities for visualization, rapid data retrieval, and manipulation in geographic information systems (GIS) have created the need for new techniques of exploratory data analysis that focus on the “spatial” aspects of the data. The identification of local patterns of spatial association is an important concern in this respect. In this paper, I outline a new general class of local indicators of spatial association (LISA) and show how they allow for the decomposition of global indicators, such as Moran's I, into ...

 

Improving Access, Utility and Analyses of FAO Forestry Statistics via Geographic Web-based Services

  
IEEE Earthzine, Vol. 5, No. 2. (2012), 378146

Abstract

[Introduction] Forests cover about four billion hectares, or 30 percent, of the Earth’s land area (FAO, 2010). At all spatial scales, from global to local, trees and forests play a critical role in human livelihoods, as well as ecosystem function and health. Monitoring the forest resource requires accurate and timely information on both extent and area change over time. The Food and Agriculture Organization of the United Nations (FAO) evaluates and compiles data on the state of the world’s forests in the ...

Abstract

Worldwide, governments are growingly focusing on free and open source software (FOSS) as a move toward transparency and the freedom to run, copy, study, change and improve the software. The European Commission (EC) is also supporting the development of FOSS [...]. In addition to the financial savings, FOSS contributes to scientific knowledge freedom in computational science (CS) and is increasingly rewarded in the science-policy interface within the emerging paradigm of open science. Since complex computational science applications may be affected by ...

 

Toward open science at the European scale: Geospatial Semantic Array Programming for integrated environmental modelling

  
Geophysical Research Abstracts In European Geosciences Union (EGU) General Assembly 2013, Vol. 15 (2013), 13245, https://doi.org/10.6084/m9.figshare.155703

Abstract

[Excerpt] Interfacing science and policy raises challenging issues when large spatial-scale (regional, continental, global) environmental problems need transdisciplinary integration within a context of modelling complexity and multiple sources of uncertainty. This is characteristic of science-based support for environmental policy at European scale, and key aspects have also long been investigated by European Commission transnational research. Approaches (either of computational science or of policy-making) suitable at a given domain-specific scale may not be appropriate for wide-scale transdisciplinary modelling for environment (WSTMe) and ...

 

The geographical relationships of British and Irish vascular plants

  
Botanical Journal of the Linnean Society, Vol. 124, No. 1. (May 1997), pp. 1-120, https://doi.org/10.1006/bojl.1996.0084

Abstract

Classifications of British and Irish vascular plants into floristic elements are reviewed. Only H.C. Watson and J.R. Matthews have attempted to devise a more or less comprehensive classification, based on the British range of the species (Watson) or the European distribution (Matthews). A new classification of 1481 native species is presented, based on their range in the Northern Hemisphere. Species are classified by their occurrence in one or more major biomes (Arctic, Boreal, Temperate, Southern) and their longitudinal distribution (Oceanic, Suboceanic, ...

 

OpenGIS Geography Markup Language version 3.3

  
No. OGC 10-129r1. (2012)

Abstract

Introduction. Geography Markup Language is an XML grammar written in XML Schema for the description of application schemas as well as the transport and storage of geographic information. The key concepts used by Geography Markup Language (GML) to model the world are drawn from the ISO 19100 series of International Standards and the OpenGIS Abstract Specification. A feature is an "abstraction of real world phenomena" (ISO 19101); it is a geographic feature if it is associated with a location relative to the Earth. So a digital representation ...

 

OpenGIS Web Coverage Service version 2.0

  
No. OGC 09-110r3. (2010)

Abstract

Introduction. The OGC Web Coverage Service (WCS) supports electronic retrieval of geospatial data as "coverages" – that is, digital geospatial information representing space/time-varying phe- nomena. This document specifies the WCS core; every implementation of a WCS shall adhere to this standard. This standard thus defines only basic requirements. Extensions to the core will define extensions to meet additional requirements, such as the response encoding. Indeed, additional extensions are required in order to completely specify a WCS for implementation. A WCS provides access to coverage data in forms that are ...

 

OpenGIS Web Map Service version 1.3.0

  
No. OGC 06-042. (2006)

Abstract

Introduction. A Web Map Service (WMS) produces maps of spatially referenced data dynamically from geographic information. This International Standard defines a “map” to be a portrayal of geographic information as a digital image file suitable for display on a computer screen. A map is not the data itself. WMS-produced maps are generally rendered in a pictorial format such as PNG, GIF or JPEG, or occasionally as vector-based graphical elements in Scalable Vector Graphics (SVG) or Web Computer Graphics Metafile (WebCGM) formats. This International Standard defines three operations: ...

 

OpenGIS Web Processing Service version 1.0.0

  
No. OGC 05-007r7. (2007)

Abstract

Introduction. This document specifies the interface to a Web Processing Service (WPS). WPS defines a standardized interface that facilitates the publishing of geospatial processes, and the discovery of and binding to those processes by clients. ―Processes‖ include any algorithm, calculation or model that operates on spatially referenced data. ―Publishing‖ means making available machine-readable binding information as well as human- readable metadata that allows service discovery and use. A WPS can be configured to offer any sort of GIS functionality to clients across a network, including access to pre-programmed calculations ...
