GPR is a geophysical investigation method. Its principle is similar to that of Seismics but instead of emitting elastic waves, it emits electromagnetic waves. They are much shorter, which leads to a much higher spatial resolution. GPR is sensitive to the electromagnetic properties of the material under investigation. Interfaces of rock formations, fi ssures and aquiferous areas are displayed.
Obviously, before any datasets can be compared or combined, they must be brought together onto the same datum (Janssen, 2009). The practice of transforming from one datum to another is not diffi cult and the necessary parameters are available in many different software packages. However, with the increased number of datums comes an increased number of ways to transform between datums.
The Global Spatial Data Infrastructure SDI Cookbook defines SDI as the “… collection of technologies, policies and institutional arrangements that facilitate the availability of and access to spatial data.” This definition (which predates the cookbook) is more than fifteen years old, and over the course of fifteen years much progress has been made toward the SDI vision of abundant, easily shared, easily used geospatial information.
While for foreign users, services are providing IRS satellite data, establishment and upgradation of ground stations for IRS data reception and RS data contributions from Indian Space Research Organization (ISRO) for disaster agreements such as International Charter and Sentinel Asia.
As you are aware GPS meets most of the navigation requirements of users. However, to improve the performance and integrity of the GPS system and to meet civil aviation requirements, the basic GPS system is to be augmented by GEO satellite with corrections and confi dences.
The Spectra Precision business within Trimble had very rapidly assembled a portfolio of optical and GNSS surveying products. While Spectra Precision had in-house engineering, design and manufacturing capabilities on the optical side, the GNSS products had been sourced from a variety of external suppliers.

On 16 January, the second of the two Galileo In-Orbit Validation (IOV) satellites, FM2 (Flight Model 2) also known as GSAT0102, started transmitting navigation signals on the L1/E1 frequency using the E12 ranging code, according to tracking reports from the COoperative Network for GIOVE Observation (CONGO). FM2 was launched together with PFM, the ProtoFlight Model (GSAT0101), on October 21, 2011.
The GIS Research Centre at Feng Chia University in Taiwan developed Taiwan’s first municipal works cloud-based map platform. It will allow city government officials and policy makers to have a clear picture of the city’s major construction projects. The platform, which was commissioned by the Taichung City Government, will integrate the city’s digital map libraries including urban planning and cadastral map libraries, and will allow users to browse records concerning the city’s major construction projects and tenders.
