One of the benefits of this data is sustainable monitoring of earth surface transformation could be monitored and mapped clearly since it has 10 meters spatial resolution.

Malang and Solo are two cities located on Java island, these cities have similar characteristics, which is inhabitant are mostly college or university students.

Malang and Surabaya are already connected by highway, however, it is only to Pandaan gate. From Pandaan gate to Malang, we still need to drive through national road, which needs another one hour to reach Malang City. A new highway is undergoing to connected Pandaan directly to Sawojajar (Malang City). This new highway (Fig. 2) will cut-down the travel time to less then an hour.
