An increasing number of thematic datasets are published as RDF graphs and linked to other datasets by identifying equivalent resources in other relevant datasets. Among the set of properties usually used as data linking criteria, geolocation (addresses, locations, coordinates ) remains one of the most commonly used. However, resources that actually refer to complex topographic features are gene...

Many evolutionary analyses assume that the positions of species geographic ranges are sufficiently phylogenetically conserved that current ranges reflect ancestral ranges and retain the historic signal of speciation. The validity of this assumption has been challenged, because there is evidence that ranges can shift rapidly and extensively. Here I test the assumption of range conservatism using...

datum Basis for measurement of position on the Earth’s surface. discrete object view Conceptualization of geographic phenomena as analogous to a tabletop littered with countable, possibly movable objects. ecological fallacy The fallacy of making inferences about individuals from aggregated data. field view Conceptualization of geographic phenomena as a set of functions over geographic space. ge...

Lately, the amount of mobility data recorded by GPS-enabled (and other) devices has increased drastically, entailing the necessity of efficient processing and analysis methods. In many cases, not only the geographic position, but also additional time-dependent information are traced and/or generated, according to the purpose of the evaluation. For example, in the field of animal behavior resear...

In India, Holstein and its crosses are being used extensively in breeding programmes and all these breeding bulls are screened for autosomal recessive genes. Blood samples are collected in ethylenediaminetetraacetic acid (EDTA) coated tubes and DNA was isolated by using phenol-chloroform method. Polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) wereperformed by using...

Location-specific Internet services are predicated on the ability to identify the geographic position of IP hosts accurately. Fundamental to prior geolocation techniques is their reliance on landmarks with known coordinates whose distance from target hosts is intrinsically tied to the ability to make accurate location estimates. In this paper, we introduce a new lightweight framework for IP geo...
