GIS will be very helpful tool in doing land use
accounting. GIS Sieve Mapping screens out of consideration those areas that
ought not to be built over due to various types of constraints such as physical
or environmental (e.g. flood prone areas) and political or legal (e.g.
protected areas). Sieve mapping is a necessary support to the land accounting
procedure because some of the areas that are not suitable may overlap and are
counted twice or many times over. With the aid of maps a particular area with
several overlapping constraints is counted only once under one constraint. This
way, multiple counting is avoided.
