Location
A device is usually located at a location. A location is something like a roof which has an owner that needs to be contacted previous to accessing the roof. So a location should have the following properties:
- id
- name
- description
- contact
- media (photos i.e.)
Position
A position is a well described geo position. A position can belong to a location. If you have 4 devices on a roof then each device has a position but all 4 devices have the same location. A position should have the following properties
- id
- latitude
- longitude
- elevation
- location
Why is this usefull?
- Location: if a device needs maintenance, you want to know as much as possible about the location you are going to access
- Position: a unified position datamodel allows quite nice things like calculating the
line of sight (LOS)
or the fresnel zone between two antennas. If you combine this with the SRTM data of NASA you can draw quite helpfull graphs like WiND of AWMN does:
