Geographic mapping of the distribution of malaria is complicated by the limitations of the available data. The most widely available data are from prevalence surveys, but these surveys are generally carried out at arbitrary locations and include nonstandardized and overlapping age groups. To achieve comparability between different surveys, the authors propose the use of transmission models, par...

Reliability and performance considerations have led to widespread use of mirror sites for content delivery. Based on measurements, redirection to a geographically closer replica is indeed valuable. Given an IP address, a mapping tool has to return the geographic location of the host to which the IP address has been assigned. This is a difficult problem because an IP address does not inherently ...

Rabies remains a disease of significant public health concern. In the Americas, bats are an important source of rabies for pets, livestock, and humans. For effective rabies control and prevention, identifying potential areas for disease occurrence is critical to guide future research, inform public health policies, and design interventions. To anticipate zoonotic infectious diseases distributio...

Geographic Information Systems (GIS) have been used increasingly to map instances of environmental injustice, the disproportionate exposure of certain populations to environmental hazards. Some of the technical and analytic difficulties of mapping environmental injustice are outlined in this article, along with suggestions for using GIS to better assess and predict environmental health and equi...

Most of the research on Phragmites australis is restricted to sites on the European continent even though P. australis occurs abundantly in many regions in the Asian and other continents under different climatic and habitat conditions. The populations used in this study were collected from different parts of Iran. All these populations were grown in the same conditions in experimental field, lo...

Availability of high resolution satellite data and advancement in Geographic Information System (GIS) together with GPS technology has provided powerful modern tools for large scale mapping, geospatial data analysis and integration enabling development of effective decision support system. Here we present a case study of ground water resource mapping in Guwahati city, Assam using these tools. I...
