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 ...

As networking and data storage technologies advance, web services have become a commonplace for data mining and sharing in an e-business model. Compared with business information, geospatial information is normally overwhelmed by the sheer volume of data. There has been a great need for the integration of web services and geospatial information to provide a platform for geospatial information d...

Data-Driven Approaches to Crime and Traffic Safety (DDACTS) integrate crash and crime data to design more efficient patrol routes for high visibility traffic enforcement. These new policies allow police to more effectively allocate their limited resources. Although the DDACTS model seems to work well in the United States, it is necessary to thoroughly study its effects before applying it in oth...

The melon fruit fly, Bactrocera cucurbitae Coquillett (Diptera: Tephritidae), is one of the important insect pests of fruits and vegetables. In order to monitor and control it effectively, it is necessary to know the potential geographical distribution of this pest. The ER (Eclosion rate) model was constructed from empirical biological data, and analyzed with ArcGIS. Based on the soil temperatu...

Dieser Beitrag fokussiert auf die Visualisierung raumzeitlicher Daten in interaktiven Webkarten unter Berücksichtigung allgemein anerkannter Design Guidelines.
