The Home | New Map | Speciality | Grid Values command creates a grid values map. A grid values map indicates the location and values of the grid nodes with symbols and labels. Posting grid values on a map can be useful for visualizing the density of the grid, as well as for verifying the plausibility of your gridded data. The frequency of the plotted grid nodes can be controlled in the X and Y directions independently. The grid values can also be displayed for only a specific range of values. You can specify the symbol type, size, color, and angle for the grid nodes. Associated data values may be placed next to the posted point. The size, angle, color, and typeface for the label can also be specified. Grid lines can also be plotted to help you visualize the grid density.
The Home | Add to Map | Layer | Grid Values or Map Tools | Add to Map | Layer | Grid Values command adds a grid values map layer to the selected map.
The grid values map displays grid node location and values for all or a subset of the grid nodes. In this example every fourth grid node value and location is displayed in the X and Y directions. The grid values layer is overlaid with a filled contour layer.
To create a new grid values map:
Click Home | New Map | Speciality | Grid Values.
Select a grid file in the Open Grid dialog. Click Open.
The map is automatically created with symbols and labels displayed across the map. The X and Y frequencies are automatically set to display approximately ten rows and columns of grid nodes.
To change the features of the grid values map, click once on the grid values layer in the Contents window or plot window. When the grid values layer is selected, the grid values properties are displayed in the Properties window.
Click on the Grid Values map layer to select it.
