Run new Process... Run new Process...
Run new Process... applies one or more geoprocessing operations to Items, creating new Items from the results.
Click Run new Process... to display the Processing Input dialog.
Note: You can also click on the launch button to display the Processing Input dialog.
You have the following options:
Use the currently selected Item(s)
If you have Item(s) selected in the Map Window this option will be selected by default but can be changed to the following option.
Use the Item(s) from an existing Overlay
If no Item(s) are selected this option will be selected and cannot be changed. In this case choose the required overlay.
Click Next.
The Processing Operations dialog will be displayed:
Select the required process.
When a process operation is selected the grey button:
will change to an active Save button:
When you have defined your new process and entered all the required property values click the Save button to display the Save Process As dialog:
Enter a Folder name and Name for the Process and click OK.
The new Process will now be added to the current NOL:
Click Next in the Processing Operations dialog.
Before the process can start the output type must be specified. The Processing Output dialog will be displayed to allow you to do this:
This dialog allows you to specify the ouput for the selected process, as follows:
Create a new Overlay for the processed Item(s)
If you select this option the Create Overlay... button will become active. Click this button to display the New Overlay Types dialog:
Create new file
Saves the file in any of the following formats:
Cadcorp Base Dataset (*.bds)
Cadcorp Feature Database (*.fdb)
Cadcorp Item Database (*.idb)
Microsoft SQL Server Spatial Dataset
This is an editable dataset that stores items in a Microsoft SQL Server Spatial database, using the planar geometry type.
See Microsoft SQL Server Spatial Dataset for the full description of the Microsoft SQL Server Spatial Dataset option.
PostGIS
This is an editable dataset that stores items in a PostGIS-enabled PostgreSQL database, using the PostGIS spatial schema.
See PostGIS for the full description of the PostGIS option.
Oracle Spatial
This is an editable dataset that stores items in an Oracle 9i, or later, Spatial database, using the Oracle Object-Relational schema.
See Oracle Spatial for the full description of the Oracle Spatial option.
Cadcorp Internal Dataset
This is an internal dataset. Contents of the internal dataset are stored within the SWD file and cannot be shared with other SWDs.
The Internal Dataset dialog will be displayed to allow the name for the new overlay to be entered.
Replace the input Item(s) with the processed Item(s)
The input Item(s) will be replaced with the processed Item(s). Only use this option if you do not need to keep the input Item(s).
Add the processed Item(s) to an existing Overlay
The processed Item(s) will be added to an existing overlay, keeping the input Item(s).
When the selection has been made click Finish.
The process will now be carried out.
