Functions

`_t`(s)
`calculate_slope_standard_deviation`(grid)	Return the standard deviation of the slopes.
`contour_points`(grid, value[, max_segments, ...])	Return a set of point segments that represent the spatial locations of contours threaded through the grid.
`derivative`(grid, derivative_type[, ...])	Return a derivative of a grid or a tilt-angle
`expression`(grids, expr[, result_file_name, ...])	Apply an expressing to grids.
`feather`(grid, width[, edge_value, ...])	Feather the edge of a grid to a constant value at the edge.
`flood`(grid[, file_name, overwrite, ...])	Flood blank areas in a grid based on a minimum-curvature surface.
`grid_bool`(g1, g2[, joined_grid, opt, size, olap])	Combine two grids into a single grid, with boolean logic to determine the result.
`grid_mosaic`(mosaic, grid_list[, type_decorate])	Combine a set of grids into a single grid.
`remove_trend`(grid[, file_name, method, ...])	Calculate a polynomial trend surface and return trend-removed grid.
`sample`(grid, xyz)	Return grid values sampled at the point locations.
`tilt_depth`(grid[, resolution, return_as, ...])	Return estimate of the depth sources of potential filed anomalies.
