In a modern mobile mapping system, the navigation component usually consists of a GPS receiver and an inertial navigation system (INS), which can provide accurate geo-referencing to the imaging sensors [1][2]. To achieve centimetre-level positioning accuracy, RTK-GPS is a natural choice. However, RTK-GPS in urban areas suffers from frequent outages due to blockages of either the GPS signals or the reference station radio links. In addition, multipath from buildings, trees and heavy vehicles could degrade the accuracy of the GPS when the vehicle is near them. ]]> http://mycoordinates.org/continuous-high-precision-navigation/feed/ 0 Maps: Changing approach http://mycoordinates.org/maps-changing-approach/ http://mycoordinates.org/maps-changing-approach/#comments Fri, 16 Apr 2010 20:20:23 +0000 admin http://mycoordinates.org/?p=7203
With the wide access to relatively inexpensive or freeware computer software for map production and using the Internet and the World Wide Web (Web) for dissemination this process has been automated somewhat, enabling the production of products and (Web) publishing to be fairly straight-forward. Using the Web as a publishing medium has allowed these relatively small voices to disseminate their viewpoint, which might otherwise be impossible...]]> http://mycoordinates.org/maps-changing-approach/feed/ 1 Exploring the moon in three dimension http://mycoordinates.org/exploring-the-moon-in-three-dimension-2/ http://mycoordinates.org/exploring-the-moon-in-three-dimension-2/#comments Wed, 15 Apr 2009 06:01:05 +0000 admin http://mycoordinates.org/?p=3040 1111

here has been a renewed interest in exploration of the moon and in the past four decades the exploration of moon has become a reality [1]. A number of missions have been flown to the moon by many countries. Many of these missions have carried imaging systems that, collectively, have returned an incredible wealth of information on the shape and surface characteristics of the moon. Mapping of moon began in the seventeenth Century by Galileo...]]> http://mycoordinates.org/exploring-the-moon-in-three-dimension-2/feed/ 0 Yes, we can! http://mycoordinates.org/yes-we-can/ http://mycoordinates.org/yes-we-can/#comments Sat, 15 Nov 2008 07:10:57 +0000 admin http://mycoordinates.org/?p=3215 The Terrain Mapping camera (TMC) on board Chandrayaan-1 spacecraft was successfully operated on October 29, 2008 through a series of commands issued from the Spacecraft Control Centre of ISRO Telemetry, Tracking and Command Network (ISTRAC) at Bangalore.

The advancement in the field of Science and Technology should be made available to the youth and to the community. As the adaptation of scientific and technological principles and developments, to maximize the use of local resources, are central to empowerment in the quality of life, the Policy recognizes the importance of emerging, modern technologies, particularly in the field of information technology and electronic media, in enabling the youth to perform and achieve in all sectors of their interest.]]> http://mycoordinates.org/when-gps-empowers-rural-youth/feed/ 0 Sampling the world http://mycoordinates.org/sampling-the-world/ http://mycoordinates.org/sampling-the-world/#comments Sun, 16 Mar 2008 12:04:56 +0000 admin http://mycoordinates.org/?p=8624
How would the world look like if you were standing on an arbitrary point on earth? It is not easy to imagine, how a randomly chosen location would look like since most pictures that come into our mind are somewhat special: our home, Piccadilly Square, a picture from National Geographic, or a photo that had been taken on top of a famous summit.]]> http://mycoordinates.org/sampling-the-world/feed/ 0 Mapping errors http://mycoordinates.org/mapping-errors/ http://mycoordinates.org/mapping-errors/#comments Sat, 15 Mar 2008 11:15:07 +0000 admin http://mycoordinates.org/?p=8468 Filipo Rodriguez, Gian Paolo Plaia Application of cognitive psychology for reduction of mapping errors Human factors contributing to mapping errors made by operators working on digital mapping systems were studied from Cognitive Psychology perspective to evolve suitable strategies to reduce errors.
