The drift angle caused by the Earth’s self-rotation may introduce rotational displacement artifact on the geolocation results of imagery acquired by an Earth observing sensor onboard the International Space Station (ISS). If uncorrected, it would cause a gradual degradation of positional accuracy from the center towards the edges of an image. One correction method to account for the drift angle...

Using Google Earth, Google Maps, and/or network visualization programs such as Pajek, one can overlay the network of relations among addresses in scientific publications onto the geographic map. We discuss the pros and cons of various options, and provide software (freeware) for bridging existing gaps between the Science Citation Indices and Scopus, on the one hand, and these various visualizat...

We provide a description of the tools and techniques used in our analysis of the VAST 2008 Challenge dealing with mass movement of persons departing Isla Del Sueño on boats for the United States during 2005–2007 1. We used visual analytics to explore migration patterns, characterize the choice and evolution of landing sites, characterize the geographical patterns of interdictions and determine ...

The packet processing system IPclip (IP Calling Line Identification Presentation) is presented. It is implemented on an FPGA board and configurable at runtime via a graphical configuration tool. The functionality is demonstrated in a localization scenario using an analysis tool and Google Earth.

Background: WHO AnthroPlus is a software which helps us to assess the nutritional status of school-age children and adolescents based on the new WHO Growth Reference 2007. Global Positioning System (GPS) with google earth is an innovative approach to map the spatial distribution of morbidities at the field level. The present study was undertaken to assess the nutritional status of school age ch...

This paper describes the digitization and utilization of Complete Map of Peking, Qianlong Period, which is the oldest measured map of Beijing made about 250 years ago. We first proposed the geometric correction method called “linepreserving distance weighting method” to preserve linear features relevant in the old map of cities. Next we improved the reliability of the old map as information inf...

Photogrammetry is becoming a highly efficient alternative technique to laser-scanning for creating virtual outcrop models. It is easy to create a 3-dimensional digital model of an outcrop and extract geological information contained in it by using photos taken from different locations and integrating few free and/or cheap software. Subsequently, both the virtual outcrop and the geological data ...

With the proliferation of geographic data and resources over the Internet, there is an increasing demand for integration services that allow a transparent access to massive repositories of heterogeneous spatial data. Recent initiatives such as Google Earth are likely to encourage other companies or state agencies to publish their (satellite) data over the Internet. To fulfill this demand, we ne...

Urban green spaces can yield considerable health benefits to urban residents. Assessing these health benefits is a key step for managing urban green spaces for human health and wellbeing in cities. In this study, we assessed the change of health benefits generated by urban green spaces in 28 megacities worldwide between 2005 and 2015 by using availability and accessibility as proxy indicators. ...
