7. GIS for land use planning > 7.4 Framework
7.4.1 Concept of Framework
Level of expertise required for this Chapter: Planner; specifically for LUPMIS @ TCPD
A Framework (Spatial Development Framework, SDF) has an indicative, ‘thematic’ map, showing where development activities and investments are to occur in a longer time frame.
Frameworks do not have precisely delineated units, but show cartographic symbols of corridors and circles, not actual spatial mapping units.
Concepts are derived from general plans on national and regional scales, and from economic and social planning considerations of the Medium Term Development Plan (MTDP).
If no MTDP exists, it is up to the planner in this stage, to express economic targets, and to define them in a crude spatial context.
Remember, a Framework is a visualization of political concepts for development, rather ideas than precise maps – unlike the Structure Plan. Requirements for precise location of geographical data are therefore not high.
The following two Chapters will illustrate the workplan (step-by-step guide, Chapter 7.4.2), primarily addressed to planners, and the GIS procedures in Map Maker to execute these steps ( Chapter 7.4.3), primarily addressed to any GIS user.
See also Chapter 7.1.1 for the role of the Framework within the entire planning concept, and its further description.

Though land use planning is based on defined methodologies, uses new technologies and requires accurate data, planning itself is not a science.
Planning is ‘manipulation for a better future’.

Background of spatial planning:
Planning at this level is a consideration of three basic spatial planning concepts:
or a sound balance of these spatial concepts.
A) Corridor development takes places along major axis in ‘buffer areas’, which are in most cases roads, either existing or improved or planned. This is also called 'arterial development'.
The buffer command in Map Maker is a very useful tool to define the spatial extension of buffers (see next Chapter, step 3).
B) Subcentre development is the planning and promotion of a number of centres in the entire planning area (also called ‘nodes’ or 'nodal development'). Size, functionality and distances of these subcentres have to be carefully planned. Not necessarily they are identical to each other.
GIS tools of creating circles and round buffers are the adequate means to define and visualize such subcentres (see next Chapter, steps 4 and 5).
C) Development of a (new or existing) centre is also a concept useful in some geographical areas and in some fields, in particular with functionalities which depend on a higher central level, i.e. not on a widespread use, such as higher administrative or service functions.
Like the spatial extension of subcentres, the GIS tools of creating circle and round buffers will be applied at the GIS.
