Perform viewshed analysis using a loaded grid file with a user-specified transmitter location, height, starting angle and radius. Watershed maps automatically calculate and display drainage basins and streams from your grid file. The two components of the vector map, direction and magnitude, are automatically generated from a single grid by computing the gradient of the represented surface. You can create vector maps from information in one grid or two separate grids. Instantly create vector maps in Surfer to show direction and magnitude of data at points on a map.

Wireframes are created by connecting Z values along lines of constant X and Y. Surfer wireframe maps provide an impressive three dimensional display of your data. Surfer determines the orientation of each grid cell and calculates reflectance of a point light source on the grid surface. Colors are assigned based on slope orientation relative to a light source. Shaded relief maps are raster images based on grid files. Base maps are created from any number of file formats, such as SHP, DXF, GeoTIFF, and PDF. Surfer can import maps in many different formats to display geographic information. Use the points to show the distribution of data points on the map, and to demonstrate the accuracy of the gridding methods you use. Post maps show points at XY locations, such as sample locations, well locations, or original data point locations. Surfer automatically blends colors between Z values so you end up with a smooth color gradation over the entire map. Image maps use different colors to represent Z values of a grid file. Overlay several surface maps to generate informative block diagrams. Change the lighting, display angle and tilt with a click of the mouse.

The 3D surface map uses shading and color to emphasize your data features. You can accept the Surfer intelligent defaults to automatically create a contour map, or double-click a map to easily customize map features.
