Points to raster

Dialog box

The Points to raster operation rasterizes a point map. The class names, IDs, or values in the point map are also used in the raster map; i.e. the domain of the point map is also the domain of the raster map. The user has to select or create a georeference for the output raster map.

Dialog box options:

Input point map:

Select an input point map. Open the list box and select the desired input map, or drag a point map directly from the Catalog into this box. No special input map requirements; you can also select an attribute from a map's attribute table.

Point size:

Type a value (integer > 0) for the size of the points in pixels in the output map. Point size 1 means each point is represented by 1 pixel in the output map. Point size 2 means that each point is represented by 2*2 pixels in the output map.

Output raster map:

Type a name for the output raster map that will contain the rasterized points.

Georeference:

Select an existing georeference for the output raster map; open the list box by clicking it. Or create a new georeference by clicking the little create button . You can usually select an existing georeference corners.

Value range:

In case the input and output map use a value domain, accept the default value range, or specify your own range of possible values in the output map.

Precision:

In case the input and output map use a value domain, accept the default precision of output values, or specify your own precision.

Description:

Optionally, type a description for the output map. The description will appear in the status bar of the Main window when moving the mouse pointer over the map in a Catalog, and in the title bar of a map window when the output map is displayed. If no description is supplied, the output map will use its own definition as description.

When you click the Show button, the dependent output map will be defined, calculated and shown. When you click the Define button, the dependent output map will only be defined; if necessary, the map will be calculated later, for instance when the map is opened to be displayed.
