Mobile industry set to boom with GPS technology
As per the RNCOS report, “Globally, the GPS market is expected to exceed US$ 30 Billion by 2008. The two segments under this technology namely people tracking & handset market will have maximum growth rate, about 9%.” Mobile industry is set to boom in 2007 with mobile giants, application developers, and OS managers planning to introduce various large-scale rollouts of GPS technology. Most phone manufacturers will introduce devices enabled for navigating with a GPS like Nokia has plans to introduce a personal mapping program that’ll let users to send messages to each other and also have instructions on how to congregate, delivered to the handset. www.rncos.com

Sunderban, one of the largest mangrove forests in the world, is located in the deltaic region of Ganga and Bramhaputra rivers in India and Bangladesh. The impact of biotic and abiotic factors on Sunderban is enormous (Rao, 1959), due to which the area has got reduced to nearly half during the past few centuries (Blasco, 1975; Naskar and Guha Bakshi, 1982; Naskar, 1985).
The mangrove-forested area of Sunderban (including portions in Bangladesh) was recorded to be 20,000 km2 by Clark (Annon., 1895), and 17,500 km2 by Prain in 1903. Grif?th (1982) reported that mangrove forests in the Sunderban covered over 4264 km2 and 4109 km2 respectively in India and Bangladesh during early eighties. The present area of Sunderban is 2081 km2 (Anon., 2001).

The debate is intense.
So are interests, and the clash of interests.
Conflicts are visible.
Equally visible is the cynicism displayed by some.
We could see all these forces at play in the Munich
Satellite Navigation Summit last month.
Still, there is a hope.
There is also a strong sense of conviction, commitment and confidence.
Galileo will happen.
It has to.
It is just a …

The ionosphere represents one of the most important error sources that affecting GPS positioning. It is strongly related to solar activity and geomagnetic ?eld. The GPS satellites and dual frequency receivers can be used to measure the Total Electron Content (TEC) of the Earth’s ionosphere. Global electron content maps have been produced by various research centers using the world-wide permanent network of GPS receivers. In this study a rapid method of monitoring the ionospheric disturbance using dual frequency GPS data of the Aristotle University Thessaloniki (AUT1) permanent station is presented. The Total Electron Content can be determined using the so called Single Layer Model (SLM) of the ionosphere. The SLM is based on the assumption that all free electrons are concentrated in a spherical layer of in?nitesimal thickness (single layer) at height H above the earth’s surface. The Total Electron Content is modeled as a truncated Taylor series with the geographical latitude and the hour angle of the sun as independent variables, using the L4 – geometry free linear combination. The results are con?rmed using global information for Sun spot and geomagnetic activity from NOAA and Kyoto University respectively.

The onset of the 21st century marked the beginning of the Asia-Paci?c era. This is the region where most of the world’s growth and economic development will occur over the next twenty years. The new millennium also signaled the birth of the urban era. Half of the world’s population now lives in cities, and that number is growing rapidly. In fact, the rate of urbanization in the Asia/Paci?c is alarming. The region currently has a population of 3.5 billion people; with that number expect to grow to 5 billion within the next 20 years. Most of that growth will occur in Asia’s cities.

This rapid urbanization presents staggering challenges for the region’s city governments. Up until now, most cities have not developed in a sustainable way. Economic development, land use planning, urban infrastructure, sewers, potable water systems, solid waste handling, and transportation systems are all inadequate to meet current needs let alone the rapid growth that lie ahead.

A review on one of the most famous european satnav symposia

The Munich Satellite Navigation Summit (MSNS) 2007 closed on March, 8th – about 400 guests from 28 nations left Munich after three days conferencing. In the run-up of the MSNS the conference advertised with the words: High quality, …

China cracks down on illegal surveying, mapping
China continues cracking down on illegal surveying and mapping and investigate and punish leaks of state secrets, said an of?cial from the State Bureau of Survey and Mapping (SBSM). Seven government departments including SBSM, Ministry of Information Industry and National Administration for Protection of State Secrets have pledged to strengthen control of the geographical information market. A total of 759 cases of illegal surveying and mapping were found in 2006, and many of the cases involved foreign organizations and individuals. Last year, two Japanese scholars were ?ned a total of 80,000 yuan and deported for mapping the coordinates of an airport and water facilities in Xinjiang Uygur Autonomous Region. It was feared their results could be used for military purposes.

GIS ILWIS migrates to open source
The Integrated Land and Water Information System (ILWIS, http:// www.itc.nl/ilwis) is a PC-based GIS & Remote Sensing software, developed by ITC. The ITC directorate has recently decided to make current ILWIS software free of charge and to migrate it as such to open source software under the 52° North initiative. Leading research organizations in the ?eld of geoinformatics (ifgi, conterra, ITC, ESRI) participate in 52° North’s innovative development for establishing open spatial data infrastructures (SDI) and transformation of these into practical technological solutions.
