After all
the information and data are being obtained and prepared, now we reach the
section of spatial analysis. In this section, different layers for each
attribute (derived from last section) would be overlaid to provide a better
understanding of the situation and lead us to our destination (modeling the
snow avalanche).

Spatial Analysis Process |
|
Natural Potential of Snow Avalanche |

|
Both snowpack volume and
vegetation forestcover are considered to be the natural factors that affect
the potential of avalanche occurrence. Combining two factors by overlaying
would sort out the area that has high potential of avalanche. |
|
On the other hand,
both tourism and mining activity are considered to be the human trigger of
snow avalanche. Combining two by overlaying would sort out the area that
has high potential of triggering avalanche.
|
|
Then it is time to
combining the natural potential and human trigger of snow avalanche to
provide an overview. By overlaying them, we could find out the area that is
potentially having snow avalanche and has the high possibility to be
triggered because of human activity. |
|
Now, we can overlay the
snow avalanche hazard layer with the human activity layer. That would map
out the area with human population that would have greater chance to
experience snow avalanche. In another word, those areas have relative high
risk of snow avalanche hazard. |
|
At the end, we once again
overlay the snow avalanche hazard layer with the transportation network.
That would give us the answer of how snow avalanche affect road network and
where. |
