Select Discover>Configuration>Grid Handlers and make sure that the following grid handlers are listed. Apart from creating grids in these formats, Discover can also import grids created in other gridding software applications including the following:ĭiscover supplies a number of Grid Handler files which enable it to create or import grids in any of these formats. The objectives of this tutorial are to interpolate a surface grid and generate a contour plan, create a profile, determine grid slope and aspect, perform sun-shading and clip the grid to a region.ĭiscover can create surface grids in 3 widely used grid formats: Geosoft *GRD, ER Mapper *.ERS and Surfer *.GRD. ![]() ![]() A topographic dataset containing spot heights is used as the data source.Īn Exercise in Surface Modelling and Analysis Elevation data, stored as a series of spot height points, are located in the table called SPOT HEIGHTS in the \Discover Tutorial \Surfaces folder. This tutorial shows how gridded surfaces and contour plans are created and used in Discover.
