Gray wolf populations have been rebounding in the Great Lakes region, after being nearly extirpated from the conterminous United States. Breeding populations of wolves have established in the Upper Peninsula of Michigan but have not yet become widely established in the Lower Peninsula (LP) of Michigan, despite several sightings of wolves in the LP since 2004. The objective of this analysis was ...

This paper describes TerraHidro that is a distributed hydrologic modeling platform. TerraHidro is general purpose water resources system that presents a new concept to represent water flows based on graph structure, in the geographic information system (GIS) context. The drainage extractions and Amazonian basin delimitations using TerraHidro have been compared with ArcGis Hydro Tools regarding ...

We demonstrate the use of sensitivity analysis to rank sources of uncertainty in models for economic appraisal of flood risk management policies, taking into account spatial scale issues. A methodology of multi-scale variance-based global sensitivity analysis is developed, and illustrated on the NOE model on the Orb River, France. The variability of the amount of expected annual flood avoided d...

The Italian Locust, Calliptamus italicus (Linnaeus) (Orthoptera: Acrididae) , is one of the most harmful species to the grasslands in Xinjiang province, China. It attacks a variety of plants in Compositae, Chenopodiaceae and Gramineae. We used CLIMEX and ArcGIS to determine the potential geographical distribution of C. italicus in China under current and future climatic scenarios. Our analysis ...

Sistem Informasi Geografis (SIG) adalah suatu sistem pada perangkat komputer yang selanjutnya digunakan untuk mengumpulkan, mengelola, memanipulasi dan menghasilkan data geografis. Materi pembelajaran mengenai SIG merupakan salah satu materi wajib dipelajari di sekolah. Namun, disisi lain proses ini masih sering mengalami hambatan, satunya diakibatkan kurangnya penguasaan terhadap sarana prasar...

Based on an analysis of the current research and application of Road maintenance, geographic information system (WebGIS) and ArcGIS Server, the platform overhead construction for Road maintenance development is studied and the key issues are presented, including the organization and design of spatial data on the basis of the geodatabase technology, middleware technology, tiles cache index techn...

This case study describes the processes involved in creating a GIS dataset to be used in evaluating risk at a sub-building level. The presentation will describe project scope (areas of interest, final products, accuracy, level of detail), production (photogrammetry, attribution from ArcGIS StreetMap USA, customized ArcPad field work), and data sources (50 year-old insurance maps, aerial photogr...
