Download User Manual (Draft)

You can edit zoning maps by pressing the Edit zoning map button on the left hand side of the
dialog. A Map window showing the Zoning map for “specific land use function” opens. With the
Grid tools in this Map window, it is possible to assign specific zoning statuses to individual cells.
In the right hand part, Zoning anticipations (for all land uses), the system allows you to
configure the anticipation to changes in the zoning status. You can specify the type of
anticipation (linear (by default) and S-shape) as well as the size of this effect. A value smaller
than 1, but larger than 0, will cause a more delayed transition and a value larger than 1 will
cause an earlier transition. This zoning anticipation acknowledges that before zoning measures
are released; already the first developments can start.
Suitability parameters
Suitability is represented in the model by one map for each vacant land use or function land use.
Values on the suitability map quantify the effect that physical characteristics of the land have on
the possible future occurrence of land uses. The suitability maps could be created with the help
of the OVERLAY-TOOL. You can select your interested land use on the dropdown list of Land
use vacant/function.
The path of the suitability map file for the first date and time is displayed by default when you
open the system. The system allows the user to add the suitability map for specific land use with
specific time by clicking on the Add and Del button. The description about how to add or delete
the map files is available in section Map file.
The user can view or edit the suitability map by clicking on the Edit button. With the opened
Suitability map for “specific land use” Map window, it is possible to change the suitability value
of individual cells. A higher value indicates a higher suitability. Suitability is displayed in the
map in colours varying from cyan to red, representing values between 0 (not suitable) and 10
(perfectly suitable). Before you add the suitability map to the system, you have to ensure that
the values on the map are integer values.
The system provides the opportunity to set up the maximum suitability (for all land uses) by
enter a value of the range of (0, 255) in the text box. This maximum suitability value should be
the highest value on any suitability map in the WAIKATO SDSS system. In general, if the
suitability map is created in in OVERLAY-TOOL, it can be used directly in WAIKATO SDSS
system with a maximum suitability value of 10.
Accessibility parameters
The accessibility for each land use function is calculated as a function of the distance to the
nearest road network. It represents how easy an activity can fulfil its needs for transportation
from a particular cell. It accounts for: the distance of the cell to the nearest link or node, the
quality of that link, and the needs for transportation of the particular activity or land use
function.
