GIS need a function to draw sketches quickly and in arbitrary scales. We propose a multiscale hierarchical spatial model for cartographic data. Objects are stored with increasing detail and can be used to compose a map at a particular scale. This results in a multi-scale cartographic forest when applied to cartographic mapping. The structure of the multi-scale forest is explained. It is based o...

BACKGROUND Despite growing acceptance and implementation of geographic information systems (GIS) in the public health arena, its utility for clinical population management and coordination by leaders in a primary care clinical health setting has been neither fully realized nor evaluated. METHODS In a primary care network of clinics charged with caring for vulnerable urban communities, we used...

The term “outlier" can generally be defined as an observation that is significantly different from the other values in a data set. The outliers may be instances of error or indicate events. The task of outlier detection aims at identifying such outliers in order to improve the analysis of data and further discover interesting and useful knowledge about unusual events within numerous application...

In this age of modern era, the use of internet must be maximized. Yeah, internet will help us very much not only for important thing but also for daily activities. Many people now, from any level can use internet. The sources of internet connection can also be enjoyed in many places. As one of the benefits is to get the on-line web mapping illustrated using open source gis toolkits book, as the...

Computer tools for spatial analysis of plant genetic resources data: 1. DIVA-GIS The DIVA-GIS software allows analysis of genebank and herbarium databases to elucidate genetic, ecological and geographic patterns in the distribution of crops and wild species. It useful for scientists who cannot afford generic commercial GIS software, or do not have the time to learn how to use it, and for others...

Dr. Stephen Huffman [email protected] [Editor’s note: This paper describes a series of maps produced by Dr. Huffman using a pre-release version of GMI’s World Language Mapping System (WLMS) GIS data set. Most of these maps have been adjusted to use the current released version of the WLMS along with GMI’s Seamless Digital Chart of the World. Images of the maps, Portable Document File (PDF) files of ...

To date, much of the work that uses Geographical Information Systems (GIS) to study human geographies applies a social science paradigm to quantitative data. There is a growing recognition of the need, however, to test whether GIS can be used to map out the qualitative ‘data’ provided by the articulation of subjective spatial experiences. This paper expands the conceptual possibilities opened u...

INTRODUCTION Snakebite accidents are an important health problem in rural areas of tropical countries worldwide, including Costa Rica, where most bites are caused by the pit-viper Bothrops asper. The treatment of these potentially fatal accidents is based on the timely administration of specific antivenom. In many regions of the world, insufficient health care systems and lack of antivenom in r...
