25. Tools
GeoSystem has three tools:
o Network Creator: ArcGIS Desktop Plugin that allows us to realize an
automatic location of devices (sensors, collectors and gateways)
considering a number of prerequisites.
o GeoStreet for ArcGIS: ArcGIS Desktop Plugin to check the location of the
network without going outside, by using 360° images (GM2).
o Network Manager: to define the fixed network, through updating groups
of sensors and collectors, and even the position of these.

27. Network Creator
Input information
The Network Creator requires the following input information:
o Potential customers
o Rush
o Counters, buildings, house numbers

28. Setting
Preliminary requirements
Distances between sensors:
In line of sight: 100 m
Without line of sight: 30 m
Distances between collectors:
in line of sight: 200 m
without line of sight: 40 m
Maximum customers:
by collector: 50
by gateway: 300
Number of groups per gateway: 7

29. Checking input data
Initial checking

30. Location of sensors
Initial phase: determination of the locations of the sensors in
the facade.
Warning signs indicate that these
steps have already been executed and
the program will remove this data (if
you ticked)
At the end of the process displays a
message indicating that the process
ended (with or without errors) for
each of the parties
Note: The user should review and relocate those sensors that the process did not find a
location in facade (Class: SENSOR_SIN_FACHADA).

31. Location of sensors II
• Contadores_Ubicacion (counters_location): "View" that determines the
location of the counters: inside or outside.
• ClientesPo (potential customers): View with potential customers by house
numbers, with the location of their counters.
• Clientes_Acometida (customer_rush): Gets the customers that are on the
beginning or end of a rush.
• Preparar edificios (make_buildings): Gets the external facades of buildings
to locate the sensors in them. You also get what will be the class
"edificios_interseccion" which will be later used to determine the visibility
between network elements.
• Ubicar clientes en fachada (customers in facade): Gets the intersections of
the rush of customers (Clientes_Acometida) with facades.

32. Grouping sensors
To group up of sensors,
Warning signs indicate that these
steps have already been executed and
the program will remove this data (if
you ticked)
At the end of the process displays a
message indicating that the process
ended (with or without errors) for
each of the parties

33. Grouping sensors II
Grouping sensors: to determine groups of sensors considering
the values established in the setting.
Set Collectors & Gateways: Determines which sensor of the
group becomes a collector and groups up the sensors to define
which of them is associated to a particular Gateway.

34. Results

35. GeoStreet
Once the pre-automatic location of fixed network is
established, this tool is used to validate its location
in the terrain without going outside.

36. GeoStreet
Plugin that displays 360° images in ArcMap.

39. Network manager
Setting
Check distances and values ​used in the calculations:
Distances between sensors:
In line of sight: 100 m
Without line of sight: 30 m
Distances between collectors:
in line of sight: 200 m
without line of sight: 40 m
Maximum customers:
by collector: 50
by gateway: 300
Number of groups per gateway: 7

40. Network initialize
It initializes the fixed network allowing us to define groups of
sensors and to asign collectors and gateways to the groups.

41. Grouping sensors
It allow us to create group of sensor and to asign the gateway to
the group

42. Grouping sensors II
It makes the following checks:
1. Check the connectivity between the sensor marked as
collector and the gateway (or one of its collectors).
2. Check the number of customers of the gateway considering
the new set of sensors.
3. Check the number of collectors of the gateway.
4. Check the number of customers in the group of sensors.
5. Specifies whether you can access from the sensor
corresponding to at least one other sensors in the group,
taking into account the distances defined in the
configuration.
6. Indicates whether the entire group was validated or not.
7. Allows the user to select a sensor (on the map) to be added
8. to the list.

43. Data checking
It allows us to check gateways and collectors.
