To the questionnaire titled “Survey of Management Requirements for the Corporate GIS”, 38 people responded.  Only 16 of those who responded, had directorates that used GIS. Except for two, the remainder of the respondents indicated that they would very much like to use GIS.  


The most frequently listed perceived benefit of a Corporate GIS was speed of access to information.  Other perceived benefits listed included: regular marketing, enhanced decision making, time saving, more efficient management, cost savings, economies of scale, good communications in head office, data conforming to specific standards, consistent and coherent information, improved quality of work, and a better understanding of how water resources in an area can be impacted. Only one respondent felt their directorate would not benefit from the use of a GIS.


Approximately 50% of the respondents felt that the Corporate GIS should be available widely within the department, in regional offices and catchment management agencies.  These respondents were currently users of GIS.  The non-users of GIS, mostly the Administration Directorate, felt that it was not necessary for the Corporate GIS to be widely used.   Advantages to distributing information widely included: wider participation in activities, speed of proper planning and access to information, transparency, more informed decision making, and as the information was already paid for – costs could be minimised by distributing it widely.   Including smaller organisations in the distribution network, generated a less enthusiastic response, with reasons listed such as these smaller organisations may have insufficient skills.  The solution to this must surely be to distribute to the outside organisations on demand, but that it would be necessary to consult with these organisations and inform them of the facilities, at appropriate stages of development.  Distribution of the database over the internet, should be investigated in future, at an appropriate stage of its development.


The question on which systems should run or be accessible through the Corporate GIS generated a unanimously positive response from those that were able to answer the question.  It was considered necessary that all GIS systems in the department, both regional and head office,  should be accessible through the GIS and as a design principle.  Outside organisations that should also be linked included: Department of Agriculture, and the Department of  Environmental Affairs.  Current strategies to achieve this include getting all new GIS initiatives in the department such as Project Planning and Forestry to ensure that their database designs and data capture standards, are such that the systems can be integrated at a later stage.  However, older systems are more problematic, and datasets frequently have to be “panel-beated” to relate to other data-sets on the corporate data-base.  Business Information feels that the application and modelling side of GIS should be driven by the end-user.


In terms of information on the data-base the following needs were identified, over and above that which is already on the database:


1)             All information that would appear on 1: 50 000 maps.

Infrastructure, topography, contours, bridges, powerlines, refuse sites, town names

Action:   Business Information to inquire about obtaining these datasets from Mowbray.


2)             Information of water infrastructure

Major dams, other dams, pumps, pipelines, boreholes, canals, gauging stations, slope/areas sites, gaps in flow gauging network, stormwater systems, sewerage treatment works, pipelines, industrial discharge points, location of new projects, DWAF sites & installations, hydrology & project data, service coverage levels, project locations, canals, water resources.

“More information needs to be provided on an item, like say dams.  At the moment the only useful information on a particular dam you can find is the dam name and the river on which it is located.  For water resources management purposes, additional information on say dam capacity, surface area volume relationship, data built, dam design parameters would be useful.  The same can be said for gauging stations, where you have the station numbers as the only information available.  It would also help if you can get information on any type of measuring structure, river on which it is, the management area in which it is, catchment area upstream of the measuring structure, date station was opened and even the flow records at the stations.  Although this information is available, it would be handy to have it on GIS.”

Water services schemes and related information.

Action:  Business Information to set up a meeting with D:Hydrology to discuss getting possibilities with respect to the above requirements.

It should be noted that some of this information will be available with the installation of the WARMS system.


3)              Cadastral data linked to land name and land ownership information (ACTEXT).  Access to SG diagrams. Registered water uses.

 Water allocation permits/ schedules.

Action:  The cadastral data with property link codes should be available on the corporate database within the next month or two.  This data set will be linked to title deed information of the property, property owner, licencing data and hopefully the postal address of the owner.  Pilot projects have been run to prove that linking these datasets is  possible.  All this will be achieved with the introduction of the WARMS project.  The data will be available on the Corporate Database.



4)             Forestry – related information

Conservation areas, agriculture, indigenous forests, commercial,provincial& national, alien vegetation, specific studies for control (GWCA + invasive plants: 1: 10 000 scale) – form outside organisations, locations of woodlots.

“Natural forest area by composition type and age class.  Woodland types (both in state and communal land).  Plantations, age class, species types, and all information from secondary proceesing including prices and production volumes and value, non-timber forest types, communities around forests and all community forestry projects, urban forestry including trees along streets and parks.  We also need fuelwood information per headlands.  Socio-economic information such as social dimensions.  Other alternative energy uses.

Action:   Business Information to meet with Forestry management to discuss a way forward.


5)             1: 50 000 Contours

Action:   Business Information has already captured a third of this entire dataset, with the remainder being captured by Mowbray.  Huge amounts of editing still have to be performed on this dataset by Mowbray to mapjoin, etc.  It is anticipated that this dataset with only be available on the CDB in the 2001/2002 year.


6)             Population and development data

Population numbers,  Dept. of Health data on location of clinics &  creches, Dept of Education data on location of schools, Dept. of Land Affairs data on location of their projects, Info. On factories, industries and farming, rural settlements, poverty indexes, census & social water service levels, social information (pop distributions, cultural data, etc.), economic information, population by income levels, rura/urban/peri-urban, income at communities.

Action:   The Census ’96 data has arrived, and is currently available over the LAN – it will be downloaded on the CDB in due course.   Business Information is currently negotiating to obtain the HELP database of ESKOM, and mapping of rural villages.   Appropriate government departments are being contacted for additional datasets. We are not having much success in obtaining industrial data.  Additional data will be sought from D:CWSS.


7)             Data at varying scales

Map grids at scales of 1/50 000 & 1/250 000& 1/500 000.

Smaller specific areas will require data at a scale of 1/10 000 .

Action:   Business Information is currently working on this strategy.  However 1/10 000 data will only be obtained for very specifically requested projects.


8)             Satellite data & Ortho-rectified photographs

Action:  currently the corporate data base will not be able to deal with large amounts of raster data.  Digital photogrammetric and statellite data (as well as the scanned 1:50 000 series) will be archived centrally with Business Information and managed through a document management system.  However, specific requested datasets of these be copied into the working-space of individual computers, and used as a backdrop against the CDB.


9)             Boundaries

Local authority boundaries, district council boundaries,  TLC’s,  catchment management areas. DWAF organisational data/  personnel characteristic of the regional staff.

Action:  Business Information to source the boundary data.

We feel that in the medium term it is better to have DWAF organisational data on the DWAF Internet/intranet homepage.


10)   Water Quality/Quantity related Information

Likely pollution products/ discharge/source

Waste disposal sites

Geohydrology monitoring boreholes

Slimes dams  (point pollution source)

HIS data

Flow rates for streams/dam levels/transfer schemes/rainfall/etc.

Outside studies on different catchments.

Action:  Some data will be provided through the WMS System.  Business Information to discuss this further with relevant Scientific Services directorates.


10)          Ecological Reserve/human reserve/international obligations/class of resource/quantity & quality of available water.

Botanical data.

Action:  Two vegetation coverages are already available on DB.  ENPAT data to be down-loaded in due course.

Business Information needs to speak to Ecological & Social Services Regarding their needs/requirements.


11)          GIS User Group Survey

Results of survey, and actions steps in Appendix.

Requested initiatives from the GIS User Group include:

1)    1: 50 000 river coverage

2)    Africa Data

3)    WGS84


Other comments:

It was clear that there is a need for GIS education in the department.  The training initiatives by Business Information were welcomed.

The response from Management to the questionaire was poor – which may indicate levels of  awareness need to be raised regarding GIS and its capabilities.  Management prehaps sees GIS as a specialist tool for the scientist.  Business Information ultimately sees GIS as a management information tool, which ultimately should be as easy as a word-processor to use.

Business Information will be offering courses on how to use the Corporate GIS towards the end of the year/  and next year.
