These are the steps to follow in order to display inside your software/web application the positions computed by Dragonfly on the floor plan image uploaded inside the Dragonfly Cloud Dashboard:

Step 1 – Determine the Floor plan ID

Determine the {FloorplanID} of the floor plan that you want to visualize inside your application. This can be done by following these steps:

1. Access the Dragonfly dashboard at at this link.
2. From the top right corner of the screen select the Site ID that contains the floor plan of interest.
3. Click on General > Floor plans.
4. Take note of the {FloorplanID} of the floor plan of interest shown under the Floor plan ID column (e.g. it is an alphanumeric string like this “jbk5aaybku“).

Step 2 – Download the floor plan KML and image

Create a function inside your application in order to download:

1. The KML file with the geo-references of the images:
   • https://s3.eu-central-1.amazonaws.com/onit.its.floorplans/{SiteID}/{FloorplanID}_a.kml
2. The floor plan image:
   1. https://s3.eu-central-1.amazonaws.com/onit.its.floorplans/{SiteID}/{FloorplanID}_a.{Extension}

Where:

• {SiteID} is the ID of the site.
• {FloorplanID} is the ID of the floor plan.
• {Extension} is the extension of the floor plan image. Please try with GIF or JPG or PNG.

Step 3 – Display the floor plan and position inside your application

Once you have the KML files and the floor plan images you have 2 options:

OPTION 1 – positions as WGS84 coordinates

1. parse the information available inside the KML file to retrieve the four boundaries of the floor plan image.
2. overlay the floor plan image on Google or Open Street map or on any other map using the info retrieved at the previous point.
3. display the WGS-84 coordinates returned by Dragonfly on the floor plan image!

OPTION 2 – positions as pixel of the floor plan image

1. display the floor plan image inside your application (without having to use the KML file and without having to overly the floor plan image on any underlying map).
2. convert WGS-84 coordinates returned by Dragonfly  into pixels of a floor plan image following the instruction at this link.
3. display the position (converted into pixels) on the floor plan image!
