Finished with setting up Octave and other things required on the PSU Virtual Machine. Also setup postGIS, which is a geographical extension of PostGreSQL. On the android client side, now the app is posting all the sensors' data to the apache server running on the VM. Now, I'm ready to run the octave scripts on the data and store the landmarks in a geo-database. [Schema is not yet decided]. Also, started working on the UI of the android app to take comments and reviews from the user.
