This paper focuses on the design of devices for handheld spatial interaction. In particular, it addresses the requirements and construction of a new platform for interactive AR, described from an ergonomics stance, prioritizing human factors of spatial interaction. The result is a multi-configurable platform for spatial interaction, evaluated in two AR application scenarios. The user tests vali...

tourism as a growing industry needs special attention in developing countries. during last decades, nature based tourism has been growing faster than other tourism fields and it seems to grow even faster. ever growing demand for nature based tourism emphasizes the necessity of a holistic planning for preserving environment against degradation. objective of this study is to present a nature base...

The study aims at developing a GIS based contamination Risk Assessment procedure in water distribution systems. Water distribution network analysis model EPANET 2.0 was integrated with ArcGIS 8.3 for the water quality analysis retrieving data from the GIS database. Water supply system of Zone VIII of Guntur, India was selected for the case study. The results of water quality simulation were dis...

Forest management depends on forest condition data and the ability to quantify impacts of activities make informed decisions. Spatially quantifying water yield (WY) from forests across large landscapes enables managers consider potential WY changes when designing plans. Current datasets are either spatially coarse or too restricted specific sites with in situ monitoring support some project-lev...

one of the new areas in the field of studying the country's development planning is border regions. although from past to present different aspects of the problems related to these regions have been studied, but spatial planning of border regions not only its position has not been clarified in the planning system of the country's development but also its dimensions and characteristics...
