Khanya under surveilance

Khanya’s main activity is in reality upheld by traveling as it stands now. The commentator always asked the question why we have to travel all these monstrous kilometers whilst we’re an ICT institution. With all the wonderful communication links we have with partner schools abroad, we still summons people to one-on-one meetings to demonstrate whatever authority and powers.

You don’t have to control people to have their co-operation. We are in an era of outcomes and if you want to control each and every activity en-route to your outcomes, you’ll add tremendous stress to your person and monetary budget.

One can still have a comprehensive record of each and everyone on the Khanya staff complement by using GIS principles and tools.

Staff member’s vehicles can be fitted with GPS tracking devices registering there geographic position 24/7. Broader planning can be submitted, cutting time on planning and reporting. Maps with traveling routes and kilometers can be generated to substantiate travel claims and to shed some more light on the traveling habits of people and possible savings and route-sharing. All cell phones are GPS devices. Cell phone users register definite coordinates at a specific time and that is another way of confirming their position. Sustainability is always an issue and this have to be tested and piloted before implementation but this is clearly the way forward in planning, monitoring and reporting in any dynamic organisation like Khanya.

Monitoring people’s whereabouts against their planning will be much easier and immediately available without physically visiting the same location.
Animals are tracked with simple Geographic Positioning Systems (GPS’s). Vehicles and movable property alike.

The questions always confronting the author are: “Why do we lose so many children through the hands of kidnappers and criminals? Is there not, for arguments sake, a moral, legal and answerable way to track all children under the age of twelve years? Are children not in essence the property of parents and government?

The implementation of this can be worked out by all our religious, moral, ethical, political, juridical and technocratic fraternities.

To have an understanding of GIS / GPS, can have great and far-reaching implications on the close life of all human beings.
Would you agree to share your under aged kid’s geographic position with government at any given time for the greater good to it?

Managing load shedding with GIS

Eskom devised a National Emergency Response plan to manage both the demand and supply side of the energy crisis. Load shedding is one of the features of this plan. According to Eskom, “Shortages on the electricity system unbalance the network, which can cause it to collapse. By rotating the load in a planned and controlled manner, the system remains stable.”

The electricity network is a complex grid of interconnected lines and related features. This network transmits power from the points of generation to the points of consumption. Eskom uses GIS (Geographic Information System) technology to manage the network.

A GIS comprises hardware, software, a geodatabase and personnel. The geodatabase is the key component of the GIS. The geodatabase stores multiple digitized data sources such as attribute tables, geographic features and information about the spatial interrelations between them, satellite and aerial imagery, surface modeling data, and survey measurements.

The GIS technology enables the Eskom personnel to locate underground pipes and cables, balance the load, plan maintenance, track energy use, and track faults.

Initially, Eskom informed consumers about possible power cuts by using a colour-coded monitor on the TV stations and on their web site. Since 31 March, Eskom implemented scheduled load shedding, which will extend to July 2008.

To generate the load shedding schedules, personnel query the database by entering an attribute or a number of attributes. The database creates a result in a table. The table can be imported into spreadsheet software so that additional data can be added.

Many the municipalities, including the City of Cape Town, buy electricity from Eskom.
