Occasionally, you may need to change the waterRIDE surface framework. Most commonly, this would be from a TIN (wrb) to a grid (wrr) to enhance performance.

Two options are available:

1. To rasterise a TIN waterRIDE™ surface (.wrb) into a grid waterRIDE™ surface (.wrr) on a grid size specified by the user. Grid surfaces pixelate when zoomed in, however, drawing and accessing grids can be significantly faster, especially for very large networks, and

2. To convert a Grid surface (.wrr) into a TIN (.wrb) by triangulating across all the grid cells.
