The Lobuche Glacier and Ice Fall Glacier are located in the Sagarmatha (Everest) National Park – Himalaya Nepal. During the Changri Nup Monitoring Expedition 2003 the two glaciers were surveyed using terrestrial laser scanner.The research program is coordinated by the HELPGroup (HIMALAYAN ENVIRONMENTAL LABORATORY PROJECT) .These researches are promoted in synergy with Ev-K2-CNR (Italian National Council of Research ).
Lobuche Glacier Lobuche Glacier -- Khumbu Valley Khumbu Valley (from 5100 m to 5400m)(from 5100 m to 5400m)The glacier was surveyed 2 times during the expedition with a time interval of 10 days in order to evaluate glacier changes.
Ice Fall Glacier Ice Fall Glacier -- Khumbu Valley Khumbu Valley (from 5400 m to 6100 m)(from 5400 m to 6100 m)The Khumbu Ice Fall glacier is the first part of the classic southern route on Everest. This glacier is constantly shifting downthe mountain. It was surveyed using the laser scanner for 3 day in continuous to evaluate ice shifting.
Six days of high mountain trekking were required to reach Lobuche and Ice Fall glaciers.Local porters and sherpa are needful for high mountains research programs
First laser data results analyzed using Reconstructor Software.
Reconstructor is developed by Institute for the Protection and Security of the Citizen of the Joint Research Centre (Ipsc-JRC) (http://ipsc.jrc.cec.eu.int/, http://mortimer.jrc.it) Inn.Tec. s.r.l – Consortium for Innovation Technology – in accordance with European Commission is official distributor of the software packages for laser data processing (http:// www.topotek.it, http:// inntec.it)
Ice surface backscatter at laser signal is good. The 3D data allows direct measurements of the glacier.
Reflector targets suitable to be survey by the laser scanner are used for range scan registration and geo-referencing.
These targets are visible at long distance (up to 2500 m) and orientation can be fixed according to the laser position.
Laser scanner survey project within the context of the 2003 Changri Nup Glacier Monitoring was carried on by the research team composed by:
Prof Cesare Alippi of Politecnico of MilanoPolo Regionale di LeccoPolitecnico fo Milano
Prof Luigi Giussani of Politecnico of MilanoPolo Regionale di LeccoPolitecnico fo Milano

External digital photos are applied on the 3D Lobuche Model using the Reconstructor SoftwareGeometrical information allows glacier surface calculation.Textured model provides additional information for glaciological analyses.
Registered scans can be compared using the Reconstructor Software Temporal comparisons can provide geometrical information on Ice Fall shifting
