The use of fundamental components of multipurpose cadastre which can be used as basic information and backbone for government policy with geographical information system as a tool are applied in this research method to appraisecampus room. The process to appraise of the facilities in a room begins with collecting facilities data which related to attribute data and defining room boundary which related to spatial data. Room appraisal are analysed by firstly calculate room valuebasedon facilities and activity hours.The method to calculate room value is comparison of quantity and functionality of facilities in every room. Thorough analysis is conducted to separate room value data containing human errors. The determination of which category (high, medium, low) every room fit in is based on distribution of value of every room value which is free of human errors. Room appraisal using this research method will lead to optimize every campus room especially low category room.

Toll roads is one important component to improve the progress of a country, because with the addition of toll roads, the accessibility easier and can advance the economic movement. One of the toll road construction that is underway is construction of Cileunyi - Sumedang - Dawuan (Cisumdawu). The Cisumdawu Toll is prepared to tackle congestion on Jalan Cadas Pangeran and facilitate access to Kertajati International Airport. The construction of the Cisumdawu toll road itself is inseparable from land acquisition problems. Land acquisition is a process to purchase community-owned land which passed by toll road. Land acquisition requires a land certificate to facilitate legal affairs, unfortunately many land in rural areas do not yet have a certificate. This certification process can be assisted by unmanned aerial vehicle (UAV) technology to map parcel data. This research examines how UAV assist in the acceleration of certification for land parcels to be acquired.
