LightSquared is a gem! I am not only talking about its nationwide high-speed 4G capabilities and that it will be a boost to our lagging IT industry which has fallen behind 18 other nations. I am focusing on how it can beautifully complement high precision applications of GPS. It is a gem for GPS high precision users and for RTK.

Positioning with GPS can be realized two main ways: i-Single Point Positioning (SPP), ii- relative positioning. When the high accuracy is required, the accuracy obtained from SPP is not enough and for those applications relative positioning method have to be considered. However in this method, there should be at least two receivers to collect the data and software to process these data.

Archaeology reflects the amazing diversity of human life across the globe (Neto, 2000). Archaeological investigations are considered as a principal source of knowledge of prehistoric, ancient, and extinct cultures. In order to reconstruct history, archaeologists rely on all the unearthed evidence, such as man-made objects, which can be as small as tools and ornaments or as large as architectural residues (Xia, 2006). Thus, it is important to explore archaeological contrivance and record them in a systematic way.

The World Bank, with the support of development partners and civil society organizations (CSO), are continuing to support the implementation of land administration and management projects throughout the world. From the World Bank side, specific support to the land sector has been provided for the past three decades. These projects have varying degrees of emphasis on social equity and economic development. In post-conflict countries, tenure security and access to land are major factors in providing long-term stability.

The Planning Commission and Ministry of Earth Sciences, Government of India conducted a workshop on National GIS on September 14, 2011 in New Delhi to discuss the National GIS vision document version 2 with all concerned involved and to formalize a national-level endorsement.
