What is a Site
A Site represents a place whereby sensors are physically located. A Site usually comprise of one or more buildings. A Site in Senfi has a geographical location and a 3D representation.
3D Representation
Users may choose to use bespoke model or user drawn model as the 3D representation of the Site.
Bespoke Model
Users can upload a bespoke model as the 3D representation of the Site. A bespoke model is one which is prepared in a 3D modelling software like Autodesk 3DS Max, Revit etc.
Advantages of using a bespoke model:
- This allows for Users to repurpose their existing BIM models as a source for the Digital Twin.
- Operators viewing the Digital Twin will get a true representation of the building's space, allowing them to get oriented easily.
User-drawn Model
Users who do not own a bespoke model may choose to use generate a quick user-drawn model. A user-drawn model is one which is drawn by tracing on a map. Currently, you can only draw one outline in the user-drawn model. This will be used as the building footprint. You can specify the number of floors in this building and the system will generate a building model for you.
Advantages of using a user-drawn model:
- Fast to generate
- Cost saving
Building/Block/Level (BBL)
3D model tends to only have geometrical information of the buildings. For ease of location referencing, Senfi uses the concept of Building>Block>Level (BBL) to refer to a particular location in the Site, E.g. Campus A > Block B > Level 5. This information is added to the 3D model during the Site creation. View Building/Block/Level (BBL) for more information.
2D Floor plan
On top of the 3D representation, it is strongly encouraged to have a floorplan associated with each level of a building/block. This makes it easy to locate things both in 3D as well as in 2D. Associating a floorplan with a level requires calibration. This process involves selecting a few corresponding points in the 3D building and the floorplan. This only needs to be done once when adding a floorplan, or when there are changes to the floorplan or 3D model.

Site ID
site_id is a unique integer associated with a particular Site. It is auto generated when the Site is created, and it is passed in as a parameter in integration to identify the Site.
