The following 12 reports were published as a result of the Territory-wide Geotechnical Area Studies Programme (GASP) carried out by GEO between 1979 and 1985. The reports contain land resources information of Hong Kong. Each of the reports cover a specific area of the region. GASP Report XII is a summary of the other 11 reports. In compiling the report, the authors have taken the opportunity to provide additional historical information on the development of Hong Kong, largely through the medium of annotated photographs, so that the report represents an important historical document in its own right.
