Converts a specified set of latitude/longitude locations to a line geometry. Output from this operation is a LineString.
Option Name | Description |
---|---|
Coordinate system | This field specifies the coordinate system to use for the line geometry. To change the default coordinate system, clear the default value then start typing the name of a coordinate system or an EPSG code to see a drop-down list of systems that begin with or contain those characters (the list appears after you have entered three alphanumeric characters). You can also click the browse button to open the Select Coordinate System dialog and select one from the list. Regardless of which coordinate system you select, the descriptive name will appear in the field and the respective EPSG code is saved for the stage. For more information on EPSG codes, see www.spatialreference.org. To retrieve a list of supported codespaces for EPSG, you can submit the SOAP request List Supported CoordSys by Code Space from the Geometry Service Demo page at |
Segment points |
The field containing the set of longitude/latitude locations to convert to a line geometry. You create this field using an Aggregator stage in Enterprise Designer to construct a list of points that gets passed to Spatial Calculator. This field must be a List of ListFieldType with two subfields Latitude and Longitude:
The following example shows the source for two lines in the following format: ID (for example, LINEID), longitude, latitude.
