China’s GI industry to exceed $10 billion by 2010
The geographic information industry is a burgeoning and fast-growing industry. Statistics from overseas authoritative institutions show that since 2000, the annual growth rate of the geographic information industry has exceeded 25 percent. More and more large international enterprises, such as Microsoft and Google.com, have begun to enter into this field. According to a recent report published in the China Economic Net website China has proposed in the Outline of the 11th Five-Year Plan for National Economy and Social Development “to intensify the construction of infrastructures and facilities for surveying and mapping, enrich, develop and utilize the fundamental geographic information resources, and develop the geographic information industry”. The report further says that the total output value (based on incomplete statistics) of China’s geographic information industry reached RMB 26 billion Yuan (more than 3 billion USD) in 2005 and the industry is becoming a rapidly rising burgeoning industry among modern service industries and a new growth point for the economy. The annual total production value of China’s geographic information industry is expected to exceed RMB 80 billion Yuan (more than 10 billion USD) by 2010. http://en.ce.cn
US agency says China used laser to jam US satellite
China has beamed a ground-based laser at US spy satellites over its territory, a US agency says. The action exposed the potential vulnerability of space systems that provide crucial data to American troops and consumers around the world. The Defence Department remains tightlipped about details, including which satellite was involved or when it occurred. The Pentagon’s National Reconnaissance Office Director Donald Kerr has acknowledged the incident, first reported by Defence News, but said it did not materially damage the US satellite’s ability to collect information. “Space is a much bigger part of our military posture than it used to be, so any effort by the Chinese or anybody else to jam our satellites is potentially a big deal,” said Loren Thompson, Defence Analyst with the Virginia-based Lexington Institute. Clearly, the incident sparked fresh concerns among US officials about the US ability to determine if satellite problems are caused by malfunctions, weather anomalies like solar flares, or targeted attacks.

GPS coming to GSM handsets
After years of anticipation, GPS technology should finally arrive in a significant number of GSM mobile handsets in 2007, according to a new study by market research analyst ABI Research, USA. The report also says that 25 percent of WCDMA handsets will incorporate GPS by the end of 2008. The factors like government regulations covering location technology for emergency services such as E911 as well as a recognized demand for LBS will be responsible for the expected rise of GPS in GSM and WCDMA handsets, according to Alan Varghese, ABI principal analyst. www.eetimes.com

The Basic role of a Hydrographic Office’s (HO) is to provide essential hydrographic Services to support safe and efficient navigation and promote national maritime development for the nation. In recent years HOs all over the world are playing leading role in development of Electronic Navigational Charts for marine community so that vessels can navigate safely on their voyage across oceans.
The GPS is a ubiquitous tool on the planet today. Its ability to pinpoint a person’s position on the globe, and store information about that location has been one of the most significant contributions to society in the latter Twentieth Century. Currently, the systematic collection of geospatial attribute data is limited to very expensive GPS receivers and specially trained personnel. The general procedure for collecting geospatial attributes with the consumer-grade GPS has required the use of “add-ons”, such as hand-held computers, laptops and palm pilots. These add-ons are frequently outside of the financial and technical reach of many communities, organizations and under funded agencies. The protocols and procedures presented here are designed to modify and merge existing methods and technologies to overcome these financial and technical barriers.
Spatial data is the fuel for 3D Applications, but all too often the fuel supplied is inappropriate. The software applied and expertise required when modelling a flood event or predicting a cityscape’s lineof-site is exactly the same using highly precise data as it is for generalised data. The difference is in how well that analysis relates to the real world … i.e. whether the analysis is correct or not. Conversely, supplying highly accurate or dense data to a generalised analysis can cost both time and money which is not reflected in the final product. Hence the word of this paper is: appropriate. Apply the most appropriate data to your application. There is nothing wrong with “approximate” or “inexpensive” 3D data, as long as it is appropriate for the level of analysis being performed.
