Abstract (AB)	Following the development of a GIS for sugar cane lands in Mauritius, the PCTIN module of Digital Terrain Modelling (DTM) was used to assist in the installation of a Centre Pivot Irrigation System. Slope maps were generated to highlight critical areas likely to affect the tower wheels. Profile analyses revealed problems with regard to the clearance of the trusses above the crop canopy. Spots where pressure head variations could arise were highlighted to enable optimization of water application. The results demonstrate the usefulness of DTM in determining the appropriate site, enabling the modification of truss spans according to terrain constraints for minimum land levelling and investments, and optimum performance.
