– A Two-day Workshop

對 地 觀 察 科 技 應 用 工 作 坊

Prominence of the Department of Land Surveying and

Geo-Informatics (LSGI) in the area of Earth Observation

(EO) for Urban Planning and Management was

demonstrated in a two-day workshop held on 20 and 21

November 2006 at the Harbour Plaza Metropolis Hotel.

The aim of the workshop was to provide a forum for

international researchers and scientists, specializing in EO,

to interact with practitioners working in different aspects

of city planning. Critical issues were examined with Hong

Kong being the point of reference. Delegates comprised

an international group of researchers, and practitioners

from Hong Kong government departments (Figure 1),

providing a mixture of top-down demonstrations and

case studies, with bottom-up feedback from user groups.

The workshop addressed four major application areas

in the light of recent technological developments in EO

including high resolution, multi-sensor systems, and

advances in computer speed and graphics capability. The

application areas were: environmental monitoring,

land use/land cover mapping, planning, and

geotechnical monitoring.

The workshop concluded:

that with the exception of thermal modeling, the

impediments to wider use of EO data in urban planning

and management are educational and institutional, not

technical; that the technology for image data acquisition

is available and its wider utilisation in cities generally,

and especially in Hong Kong, is mainly dependent

on increased awareness of its availability among
