3/3/2014 ESC 4511 REMOTE SENSING Lab week 2

This is what i had learnt and done today. No idea of what it is? Basically what we learnt today mostly focused on remote sensing algorithms. From my understanding, algorithms actually is a system that utilize formulas to convert unreadable digital data to readable data through computers. This serve the purpose for the users to read and analyse the data.

Through today lab, we were able to use Ermapper, insert unreadable data through land satellite. Format of the file were ERS file. Then the file undergo varies steps for example contrast setting, changing band colour, add in layers and etc before turning it into 3D view as above. Afterwards we were given task to look for houses, but we could'nt find it. We were very disappointed.

Why is that the algorithms in remote sensing is important in remote sensing. As i mention before, algorithms serve the purpose of converting unreadable format to readable format. This step is important in term of later work regarding map studies or GIS studies. For example, GIS mapping requires raster data that is readable. Other examples were, map making which important in country planning and so on. 

In a nutshell we won't be here if it wasn't because of algorithms of remote sensing. The end.
