spatial levels: that of strategic urban planning; and that of detailed local area planning
(also known as neighborhood planning) in which site development and control
functions are performed. Furthermore, UPM draws a distinction between planned
and unplanned development. The aforementioned dis-
tinction is crucial because it provides a basis for exploring
and understanding the spatial and temporal characteris-
tics of the typical objects (and hence the kinds of
remote sensing image data) that need to be considered at
both levels of planning. Broadly speaking, the strategic
planning level requires spatial data with lower spatial
and temporal resolutions than the local area planning
and development control level. Nevertheless, a detailed
examination of the specific activities is needed to deter-
mine the optimal spatial and temporal requirements for
a given situation.

Planning and Management of Urban Development
UPM is a discipline that seeks to create institutional frameworks and regulatory
processes that can lead to the creation and maintenance of high-quality, sustainable
urban environments. Providing and maintaining basic urban infrastructure (e.g.,
roads, and networks for energy, communication, water supply and sanitation), and
regulating the construction and use of buildings and land are key UPM process
components that are concerned with changes in the physical or built environment.
As physical urban development generally entails considerable private and public
investments with long economic life spans, formal planning and coordinated devel-
opment is generally desirable.
A Model of Urban Development and Planning
The urban planning process seeks to allocate available and developable land for
urban functions, facilitate its servicing, and regulate access to the land by various
public and private actors. These actors then pursue their development goals within
the spatial development framework or plan.
The entire urban planning process is generally divided into two phases (Baross
1987 ):
Phase 1 - City Development: Public authorities undertake broad zoning of land
(land use planning) and provide trunk infrastructure. Public and private developers
consolidate land in preparation for actual site development.
