Positional Accuracy Improvement Legacy Dataset Cadastral Modernization
2016/10/14
Cadastral map is a parcel-based information which is specifically designed to define the limitation of boundaries. In Malaysia, the cadastral map is under authority of the Department of Surveying and ...
Ionospheric biases correction for coordinates derived from GPS single point positioning
GNSS Global Positioning System singlepoint positioning
2015/9/10
Most GPS users employ low cost receivers. These receivers do not allow users to record the pseudorange that
they observe, but the computed coordinates. This work presents an original and simple metho...
Georeferenced cartography dataset of the La Fossa crater fumarolic field at Vulcano Island (Aeolian Archipelago, Italy):conversion and comparison of data from local to global positioning methods

The present study illustrates the procedures applied for the coordinate system conversion of the historical fumarole positions at La Fossa crater, to allow their comparison with newly acquired global ...
Development of subsurface positioning system using electromagnetic method
electromagnetic methods magnetic field subsurface pipe
2009/3/5
It is useful to employ jacking method for construction of lifelines. We have developed an electromagnetic positioning system of underground pipes at the depth between 10 and 15 m. This system consists...
