In order to adequately model ecosystems services of the urban environment, it is necessary to accurately inventory urban vegetation abundance and spatial distribution. An object-based, methodological design for estimating urban vegetation structure within the metropolis of Phoenix, Arizona using remote sensing techniques on high-resolution (0.6m) aerial photography was derived utilizing a hybri...

In this paper, we analyze probability density functions (PDFs) of scatterings derived from fully polarimetric synthetic aperture radar (SAR) images for improving the accuracies of estimated urban density. We have reported a method for estimating urban density that uses an index Tv+c obtained by normalizing the sum of volume and helix scatterings Pv+c. Validation results showed that estimated ur...

Urban indicators are efficient tools designed to simplify, quantify and communicate relevant information for land planners. Since urban data has a strong spatial representation, one can use geographical data as the basis for constructing information regarding urban environments. One important source of information about the land status is imagery collected through remote sensing. Afterwards, us...

Impervious surface has been recognized as a key indicator in assessing urban environments. However, accurate impervious surface extraction is still a challenge. Effectiveness of impervious surface in urban land-use classification has not been well addressed. This paper explored extraction of impervious surface information from Landsat Enhanced Thematic Mapper data based on the integration of fr...

This work is concerned with extracting straight lines in SAR image areas for application of urban analysis. The methodology combines the Hough transform and the line detectors algorithms proposed in Tupin et al. [2] to extract the main axes in road networks. A real SAR image is used to test the proposed algorithm.

A nurse residency program's best practice recommendations are presented within this article and are organized around three processes: establishing the program infrastructure, creating a multistaged evidence-based program, and sustaining the program through appropriate evaluation and dissemination of results. These recommendations represent lessons learned and key findings derived from a team of...

It is a great pleasure for me to attend the Fourth Annual Forum on City Informatization in the Asian-Pacific Region while having this opportunity to exchange views with the distinguished guests. IT Promotes Development, the theme of the annual forum which fully reveals the significance of sustainable development of informatization and its role in the development. This is a theme which attracts ...
