“Great interest currently exists for developing ecosystem models to forecast how ecosystem services may change under alternative land use and climate futures. Ecosystem services are diverse and include supporting services or functions (e.g., primary production, nutrient cycling), provisioning services (e.g., wildlife, groundwater), regulating services (e.g., water purification, floodwater retention), and even cultural services (e.g., ecotourism, cultural heritage). Hence, the knowledge base necessary to quantify ecosystem services is broad and derived from many diverse scientific disciplines. Building the required interdisciplinary models is especially challenging as modelers from different locations and times may develop the disciplinary models needed for ecosystem simulations, and these models must be identified and made accessible to the interdisciplinary simulation. Additional difficulties include inconsistent data structures, formats, and metadata required by geospatial models as well as limitations on computing, storage, and connectivity. Traditional standalone and closed network systems cannot fully support sharing and integrating interdisciplinary geospatial models from variant sources. To address this need, we developed an approach to openly share and access geospatial computational models using distributed Geographic Information System (GIS) techniques and open geospatial standards. We included a means to share computational models compliant with Open Geospatial Consortium (OGC) Web Processing Services (WPS) standard to ensure modelers have an efficient and simplified means to publish new models. To demonstrate our approach, we developed five disciplinary models that can be integrated and shared to simulate a few of the ecosystem services (e.g., water storage, waterfowl breeding) that are provided by wetlands in the Prairie Pothole Region (PPR) of North America.”

GIS-Based Evaluation of Soybean Growing Areas Suitability in China

IFIP Advances in Information and Communication Technology, 2011, Volume 346, Computer and Computing Technologies in Agriculture IV, Pages 357-366

“In this study, the suitable areas for soybean in China were presented by GIS-based Multi-Criteria Evaluation (MCE) approach. We collected datas of environmental conditions and soybean growth associated factors, then, by the GIS technology we established spatial database of regional weather, topography, and soil conditions. Using the Spatial Analyst, the Spatial Interpolation, the Reclassification and the Weighted Overlayof ARCGIS9.2 operated to the database. Then the suitable criteria map of soybean in China was created, and the potential suitability of soybean planting areas was evaluated. The results showing 5,960,271 km2 of areas are fit for spring soybean and 5,286,643 km2 of areas are fit for summer soybean in the Northeast Plain, the Huang-Huai Plain and the Yangtze River Delta, in addition, there are lots of scattered suitable areas for soybean cultivation. This present study was aimed to provide some value references for Government formulating policies on the adjustment of industrial structure, and some reasonable guidance for farmers cultivating the agricultural products, more importantly, to achieve the purpose of utilizing natural resources reasonably.”

Modelling Sustainability

Mathematics and Computers in Simulation, Volume 81 Issue 7, March 2011

Vladislav Todorov and Dora Marinova

“The article presents a general classification of the models being developed in the area of sustainability arguing that the existing models represent the historical conceptualisation of sustainability starting from environmental constraints and moving towards economic valuation and social behaviour and policies. Coupled with computer power, sophisticated models with a varying levels of complexity have also been developed (static/dynamic; local/global; specific/general). However as any model is a simplification of the complex reality, the main purpose of any sustainability modelling (and the newly emerging area of sustainometrics) should be to allow dynamic representation, including the co-evolution of the sustainability systems and the role of humans as sustainability guardians.”

Grid-enabled Spatial Data Infrastructure for Environmental Sciences: Challenges and Opportunities

Future Generation Computer Systems, Volume 27 Issue 3, March 2011

Gregory Giuliani, Nicolas Ray, and Anthony Lehmann

“Spatial Data Infrastructures (SDIs) are being widely used in the environmental sciences to share, discover, visualize and retrieve geospatial data through Open Geospatial Consortium (OGC) web services. However, SDIs have limited analytical capabilities, an essential task to turn data into understandable information. Geospatial data are typically processed on desktop computers, but their limited power limits the types of analyses that can be conducted given ever-increasing amounts of high resolution data. With the recently introduced Web Processing Service and the availability of large storage and computing facilities offered by Grid infrastructures, new opportunities are emerging within the environmental sciences communities. The enviroGRIDS project, funded by the European Commission ”Seventh Framework Programme” (EU/FP7), will target these issues.”

Johann Lambert’s Classic “Notes and Comments on the Composition of Terrestrial and Celestial Maps” Republished

Notes and Comments on the Composition of Terrestrial and Celestial Maps, recently republished by Esri Press, brings to light the work of Johann Heinrich Lambert, a man whose work constitutes the beginning of the modern period in mathematical cartography.

The original German edition, published in 1772, introduced several distinct map projections created by Lambert that are still in use today. Unavailable for several years, the 1972 English translation by noted geographer Waldo R. Tobler has been enhanced to include an expanded preface and updated reference section in its new release.

“The subject of map projections has seen important contributions from many remarkable individuals, with Johann Lambert [being] one of the foremost authorities,” says Tobler.

Tobler is a leading geographer and cartographer who has authored and coauthored many influential articles and papers on cartography and map projections. He is professor emeritus in geography at the University of California, Santa Barbara.

Notes and Comments on the Composition of Terrestrial and Celestial Maps (ISBN: 978-1-58948-281-4, 132 pages, $24.95) is available at online retailers worldwide, at esri.com/esripress, or by calling 1-800-447-9778. Outside the United States, visit esri.com/esripressorders for complete ordering options, or visit esri.com/distributors to contact your local Esri distributor. Interested retailers can contact Esri Press book distributor Ingram Publisher Services.

Through its Classic Series, Esri Press preserves important scholarship in the field of cartography by republishing seminal texts that are no longer in print. Other books in this series include Semiology of Graphics by Jacques Bertin, The Look of Maps by Arthur H. Robinson, and Cartographic Relief Presentation by Eduard Imhof.
