FoR SMartServer 3.3 and prior releases, the LOCATIONS widget is called the Map Widget.

You can create contexts to organize devices within the SmartServer IoT to mirror their locations within the physical site to facilitate effective system planning and navigation. A context is a digital representation of a real world region, area, or space. You will use the CMS Planning widget (introduced in SmartServer 2.8) to view, create, organize, edit, and delete contexts. Other CMS widgets use the context information to organize your devices by the contexts you define. For example, you can organize sequence of operations, dashboards, and connections by contexts. See the SmartServer IoT Node-RED Tutorial for a getting started tutorial on creating a sequence of operation and applying it to a context within the system.

For each context you create, you select a context type which can be a region, campus, building, floor, room, or area. A campus may be a region, such as Northern California, a site such as the Olympic Village, or a campus such as the University of California. An area may, for example, be an area in a campus, such as a parking lot or street, or an area on a floor such as a VAV zone. An area can also be created within a region. You can associate other system entities such as datapoints, devices and users with these contexts to provide a physical location reference to these entities.  For example, you can use contexts to identify select specific devices or user interfaces such as the following:

9. Optionally, set the Base Point: x / y reference for measuring distances and positioning contexts and devices in relation to the drawing. The base point is specified as the pixel x,y coordinates of the starting point of the drawing coordinate system. The default base point is 0, 0 representing the upper-left point, which is the first point in the image. For the building context, this field is not used for calculations.
   
   
10. Optionally, set the True North Angle, which is specified as true north angle - project north angle. That is, if the project north angle is oriented straight up, and with that orientation true north is 90 degrees, then the angle to true north is 90 (90 - 0). The default true north angle is 0 degrees. This value may be fractional. For the building context, this field is not used for calculations.
    
    
11. Optionally, set the Drawing Scale, which is the number of pixels per linear meter (number of pixels / linear meters). This value may be fractional. The default is 3 pixels per meter. For the building context, this field is not used for calculations.
    
12. Optionally, set the Geographic Location: Latitude / Longitude, or click the Set Location () button. These fields define the real-world location of the base point in latitude and longitude coordinates. For the building context, this field is not used for calculations.

...

1. Hover over the building context and then select the Create Child Context button ().
   
   
   
   The Create Child Context view appears.
   
   
   
   
2. Enter the context parameters as appropriate, including:
   
   
   • Name – name for the floor.
   • Type – Floor. This type is the subsequent context type that contains room and area context types and contains the floor plan image. It defines a physical floor in a building and is comprised of one or more rooms. A floor context type nested below the building are geolocated relative to the building context type they are nested below. A floor and room context type nested below the building are geolocated relative to the building context type they are nested below. The room and area context types defined below the floor context type are relative to their position assigned on the floor plan image.
   • Description – optional description.
     
     
     
     
3. Click the Import Image Floor area and upload the selected floor plan image from your computer. For devices to appear where they are expected on the map, continue with the steps below setting Base Point, True North Angle, and Drawing Scale. 
   
   
   
   
4. Set the Base Point: x / y reference for measuring distances and positioning contexts and devices in relation to the drawing. The base point is specified as the pixel x,y coordinates of the starting point of the drawing coordinate system. The default base point is 0, 0 representing the upper-left point, which is the first point in the image. 
   
   
5. Set the True North Angle, which is specified as true north angle - project north angle. That is, if the project north angle is oriented straight up, and with that orientation true north is 90 degrees, then the angle to true north is 90 (90 - 0). The default true north angle is 0 degrees. This value may be fractional. 
   
   Example:
   
   
   1. Consider the following location on the map (the arrow points to true north): 
      https://www.google.com/maps/@37.2921622,-121.9884976,475m/data=!3m1!1e3

      
      
      
      

   2. The floor plan appears as follows (the arrow points to true north):
      
      
      
      

   3. Measure the angle (green arrow) between true north (red arrow) and current "north" (black line). Always calculate the true north angle in a counter-clockwise direction.
      

      
      

      
      
      

      For this example, the true north value is 132.25 degrees.
      
      
6. Set the Drawing Scale, which is the number of pixels per linear meter (number of pixels / linear meters). This value may be fractional. The default is 3 pixels per meter. 
   
   Example:
   
   
   1. Measure the size of the building (360.20m for this example).
      
      
      
      

   2. Determine the pixel size of the image (662 for this example). For a Windows PC, the pixel size is displayed with the image file. For a Mac, right-click the image file and select Get Info.
      
      
      
      

   3. Calculate the drawing scale.
      
      For this example: 662 / 360.20 = 1.84 pixels per meter.
7. Set the Geographic Location: Latitude / Longitude, or click the Set Location () button. These fields define the real-world location of the base point in latitude and longitude coordinates. 
   
   
   
   
   1. If you click the Set Location button, then the following view appears:
      
      
      
      

   2. Zoom in on the map to set the building location. The latitude and longitude fields are set based on the building coordinates.
      
       Use the + button to zoom in and the - button to zoom out on the map. You can modify the geoposition by first clicking the Edit button (), and then clicking and dragging the handles or marker. Save or cancel edits by selecting the appropriate option .

      
      

      

   
   
   
8. Optionally, set the Custom Fields (Tag / Value) pairs.
   
   
9. Click Save.
   
   The Planning widget appears with the floor you created.
