The 2D Scatter Point module is used to interpolate from groups of 2D scattered data to other objects (meshes, grids, TINs). Several [[GMS:Interpolation|interpolation]] schemes are supported, including [[GMS:Kriging|kriging]]. | The 2D Scatter Point module is used to interpolate from groups of 2D scattered data to other objects (meshes, grids, TINs).

A number of [[GMS:2D Scatter Point Tool Palette|tools]] are included for creating and manipulating 2D scatter point sets. In general, 2D scatter sets are imported using the [[GMS:File Import Wizard|''File Import Wizard'']]. 2D scatter sets can also be [[GMS:2D Scatter Point Set Creation and Editing|created]] from other objects in GMS such as GIS objects, feature objects, meshes, grids, TINs, etc. | |||
Multiple 2D scatters sets can be in the module. Existing scatter sets can be duplicated or merged together. | |||
Besides interpolating 2D scatter sets to other data, the module can also be used to [[GMS:Converting 2D Scatter Points to Other Types of Data|create objects (meshes, grids, TINs)]] from the scatter data. | |||
The module contains its own [[GMS:2D Scatter Point Display Options|display options]] which include [[GMS:Contour Options|contour]] displays. Also, each scatter point has an [[GMS:Active/Inactive Points|active/inactive]] status. A scatter point with an inactive status can be displayed, but the dataset value at the point is ignored when interpolation takes place. | |||
The 2D Scatter Point module also allows exporting scatter sets by right-clicking on the scatter set and selecting the '''Export''' command. Options for export include: Text Tab Deliminated 2D Scatter Point Files (*.txt), Text GMS 2D Scatter Point Files (*.xy), and Shapefiles (*.shp). | |||
