Point Options

This set of preferences allows you to set the point updates for each persistent update. Point updates are changes applied to a corresponding point (Latitude, Longitude). For a particular point, you can: exclude the point, set the speed of the point or change (increase or decrease) the speed of the point by a value or percentage.

You can add only one point at a time by specifying the longitude and latitude values and selecting the desired update to be applied. You can only modify the updates corresponding to a single point at a time. While modifying, the selected point and the corresponding updates will be displayed, however you can not change latitude and longitude of the point.

Note: Clicking the save button will add all the persistent updates displayed in the list. You can delete updates from this list prior to saving. Once saved, the only way to remove the updates is to reset using the Reset Updates control.

Table 1. Point Update Options
Option	Description
Select Database	The name of the database that contains the data to use in the update process. Use the database name specified in the Spectrum Spatial Routing Database Resource tool. For more information, see the Spectrum Technology Platform Administration Guide.
Coordinate System	The coordinate system of the input coordinates. 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 `http://<server>:<port>/Spatial/GeometryService/DemoPage.html`.
Latitude/Longitude	The point to perform the persistent update. You must specify a point which consists of a Latitude and Longitude.
Exclude	Select this to exclude the specified point from all route calculations.
Override	Select this to set the new speed of the specified point from all route calculations. Define the new Speed, and set the Speed Unit (kilometers per hour, miles per hour, meters per minute, or meters per second).
Increase or Decrease	Select this to increase or decrease the speed of the specified point by a defined velocity. Define the amount to increase or decrease the Speed, and set the Speed Unit (kilometers per hour, miles per hour, meters per minute, or meters per second).
Percentage Change	Select this to increase or decrease the speed of the specified point by a defined percentage of the points current velocity. Define the percentage (positive or negative) to increase or decrease the speed.
