站点

如整体概念所指出的，站点是实在放置传感器的地方。每个站点都有一个分配的ID（site_id），而开发者在与Senfi集成时可使用该ID。

建筑物，楼，层

一个站点通常包含建筑物，这些建筑物可能由不同的大楼组成。每个大楼都由多个楼层组成。因此，Senfi中的站点组织为：建筑物>楼>层，或简称BBL。

模型类型

Senfi支持两种类型的模型。

1. 定制模型
2. 手画建模

定制模型

定制模型是使用3DS Max等三维建模软件准备的模型。定制模型中已经存在建筑物/楼/层的信息，而这些信息是无法在内容管理系统中更改的。

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. You can modify the building, block and level of a user-drawn model.

Floorplan Calibration

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.
