Today the MODEL MAKER digital terrain modelling (DTM) software package is well known and widely used nationally in South Africa and internationally in the fields of land survey, engineering, mining and construction. Since the beginning of its design in 1980 it has been continuously enhanced to keep it in line with industry demands and the latest computer technology.

imBannerDuring 1994 the addition of computer aided drafting (CAD) functions increased the use of the program. With the addition of an irrigation design module during 1998 it is now the only software package available that provides the user with user-friendly and well supported functions for DTM, CAD and Irrigation design in one package. The system operates independent of other commercial software and provides its own plotting and reporting capabilities.

Model Maker's irrigation design system is made up from the Model Maker DTM software modules 1,2,6 & 17 (see the modules described under Model Maker) and is internationally marketed as Irri-Maker by Model Maker Systems from South Africa and Senninger Irrigations, Inc. from Orlando, Florida in the USA.
