Land Use and Land Cover Mapping of PRD and HK

LULC Mapping of PRD and HK

With increasing economic and social integration between Hong Kong and other cities in the Pearl River Delta (PRD), there is a growing need to take into account regional dimensions in our land use planning, such as urban development, infrastructure provision and nature protection. It is crucial to keep abreast of the land use development within the PRD.

The Land Utilization Map of Hong Kong (LUM HK) is prepared annually by the Planning Department (PlanD). The broad land use pattern of the PRD region was recorded in the PRD Land Utilization Map (PRD LUM) prepared back in 2003.

As a major city in the PRD region, both LUM HK and PRD LUM are needed to support regional as well as local planning. The rapid urbanization of many PRD cities in the past decade has fundamentally reshaped land use and landscape of the region, it is therefore necessary to provide a broad overview as well as visualization platform upon reviewing the methodology and land use classification in updating the PRD LUM and LUM HK. It is expected to establish a robust and efficient mechanism to support systematic retrieval and maintenance of various information.

The primary objective of the Study is to provide the latest available satellite images and broad land use data of the PRD areas to facilitate better understanding of the current land use and development pattern of PRD and assist the Review of the Territorial Planning Strategy under the HK2030 Study and regional planning in general, as well as to provide LUM HK by using the developed Hybrid MOOSC method in the rural and urban areas of Hong Kong.

Some deliverables in this Study include:
