Conclusions
An extension of Tomlin’s directional identifiers is proposed, allowing the modelling of non-planar features. Along with this, the integration of time- dependent travel cost variables is achieved through linking MFworks with an external Visual Basic application for updating the cost-of-passage surface, demonstrating that such interaction extends the inherent capabilities of a GIS engine. Another conclusion to be drawn from this paper is that network analysis in raster GIS is a variant of surface analysis.
