Overview

• Objectives of the SDI act • SDI role players • Standards implemented at the NGI • Examples of the implementation

• Save the date • Today's offerings from the WCSIF

• The establishment of the (CSI) Committee for Spatial Information.

• The establishment of an electronic metadata catalogue and provide for the capture and publishing of metadata.

• Avoiding duplication of Geo-spatial data capture.

• The determination of standards and prescriptions with regards to the facilitation of sharing of spatial information.

Standards implemented at the NGI SANS 1880 – SAGDaD feature content catalogue

Code: 57 Name: Road Definition: A path or way used by vehicles, pedestrians and/or animals. Aliases: Attribute: Enumerated_type Values: 1. National freeway A limited-access, dual carriageway free of obstructions with a minimum speed limit to keep slow vehicles off the

freeway. These roads carry an “N” designation. 2. National road The main network of roads linking cities of national importance, harbours and some border towns. The national routes

form the country's major road transport infrastructure and are maintained by the national government. 3. Arterial road A wide, busy road that joins important towns and cities in each province to the national route network. The government

of each province is responsible for their own arterial roads.

4. Main road A road linking large towns which are not on national or arterial routes, to the nearest major centre or city. Both local

and provincial authorities maintain main roads.
