Using Visual Basic to Enhance ArcInfo ArcGRID Author: Chip Hankley 3817 Mineral Point Road Phone: 608-262-2320 Although the GRID module of ArcInfo provides a flexible modeling environment, some operations or conditions may result in extraordinarily slow GRID calculations. Using the multidimensional array capabilities of Visual Basic (VB) and Visual Basic for Applications (VBA) can mimic the raster environment of GRID, yet perform spatial operations much faster. This paper demonstrates some of the performance differences between GRID and VB as well as simple techniques for transferring GRID data between ArcInfo and VB/VBA. |
