4. Daily use of GIS for Land Use Management
DATA STORAGE AND DATABASE DESIGN
Geo-Informatics is the custodian of all LUMS core datasets, which
consists of spatial and attributes tables. The data is sourced by GIS
as approvals takes place and this is published on Intranet and Internet
GIS viewers;
Spatial and attribute data layers are housed in an Enterprise database
(Oracle 10g) in a Spatial Data Object (SDO Geometry) format;
Town Planning scheme data is stored in a 3 phase layer system
depending on property status. Layers are:
• Scheme Proposed (amendment scheme approved but
property not registered)
• Scheme Parcel (registered property)
• Scheme History (Parcels that changed in zoning
or legal status)
DATA STORAGE AND DATABASE DESIGN
Table structures are setup to accommodate data for the existing (19
Town Planning Schemes still in operation) and proposed (Land Use
Management Scheme for Ekurhuleni area);
Table structures are also designed to ensure constant data integrity
when spatial and attribute data are transferred between layers; and
Secondary Town Planning layers such as: Line of no access,
building lines, height zones, etc. are also updated in conjunction
with zoning changes.
LAND USE MANAGEMENT SCHEME PROJECT
In house preparation and compilation of a Uniform Land Use Management
Scheme for EMM from 19 existing Town Planning Schemes and BCDA
into a uniform EMM Land Use Management Scheme.

LAND USE MANAGEMENT SCHEME PROJECT
A LUMS Task Team was established, which includes planners, as
well as GIS Specialists;
All properties’ existing zonings were captured in GIS database;
Scans of additional rights/ restrictions in terms of Annexures and
Consent approvals were made – Hyperlinks created;
A LUMS grid (1:2 000) was created in GIS database; and
A customised GIS Viewer was created to show the planners the
current zonings for comments and corrections.
LAND USE MANAGEMENT SCHEME PROJECT
An Arc Reader Package was also created with current zonings for
comments and corrections;
Town Planners set up a Conversion Table for the existing 19 Town
Planning Schemes’ categories to the uniform Land Use Management
Scheme categories;
Bulk conversions of existing Zonings were done in database
according to conversion table;
Each of the existing TPS has a unique code that is also in the GIS
database. This was used to create queries for the bulk conversions;
and
All properties with additional rights in terms of ‘Annexures’ and
‘Consents’ were flagged.
LAND USE MANAGEMENT SCHEME PROJECT
All flagged properties were individually evaluated by LUMS Task Team
and conversions were updated in database;
Properties with ad hoc conversions were marked in the GIS database to
distinguish them from the bulk conversions;
Again a customised GIS Viewer was created to show planners the
conversions/ proposed zonings that were done, for comments and
corrections; and
Again an Arc Reader Package was created with proposed zonings for
comments and corrections.
LAND USE MANAGEMENT SCHEME PROJECT
Sometimes slight changes to bulk conversions were necessary as
draft LUMS evolved. This needed updating in GIS database;
Hard Copy scheme maps (1:8 000 grid) with new zoning categories
were printed for each of the 19 TPS for corrections in the respective
Customer Care Areas for those not comfortable with technology;
Hard copy maps with changes were updated in GIS database.
While the project is running, new zonings changes are still being
effected in the GIS.
Project nearing the stage of Public Participation.
SYNERGY OF GIS AND LUMS
Collecting zoning information from all the existing Town Planning Schemes;
All stakeholders will be able to view zoning and development controls on the GIS;
Billing/valuation system scan benefit from the zoning information captured in GIS;
Transferring existing zonings to the new EMM scheme; and
Updates to the scheme will be done with the help of the GIS database.
