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 |
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.
