This topic focuses on the procedure to identify GPS Lat, Lon point from a GPS calibrated drawing.

For a similar procedure using the Map tool see this topic.

 

Prerequisites

This topic assumes that you have a GPS Calibrated drawing of your plant.

For more information on calibrating your drawing see this topic.

 

Explanation

The WireCAD Locations table within the project database contains fields for named locations within your plant. In addition, those named locations can be associated with GPS coordinates.

There are four fields to contain the GPS data:

•GPSLat - Latitude decimal precision 18 decimals.

•GPSLon - Longitude decimal precision 18 decimals.

•GPSEl - Elevation decimal precision 18 decimals.

•GPSLocation - text convenience field of the Lat,Lon.

 

Note: We realize that 18 decimal places is far beyond the capabilities of any non-stationary GPS receiver. We just want to be thorough.

WireCAD provides a tool to identify the GPS coordinates from your GPS calibrated drawing and fill the field data appropriately.

 

1.Open your GPS calibrated drawing. If your drawing does not display GPS in the lower right-hand corner, stop.

2.Click Mapping Tools > Tools > ID GPS Location Coords. This will open a dialog from which to select the Location of interest.

3.Select the row(s) of interest within the Locations grid. Here we will define the GPS coordinates for the Location "AMU.COM CTR CORE SWITCH.ROOM 120.5".

4.Click Pick > . The ID dialog is temporarily dismissed to allow you to pick the coordinate from the drawing.

5.Pick the coordinate by moving your cursor to the coordinate in the drawing and left-click. If you have selected [Leave Location Marker] as we have here you will leave behind a location marker at the point you have picked.

6.The ID dialog will be shown with the coordinate data in the selected row(s).

 

7.Click File > Save.

8.You are done.
