A GIS water management system was developed using free and open source software as a strategic element for smart cities. The existing proprietary solution had limitations including a generic data model, restrictions on external system connections, and limitations on publishing information. The migration process involved redesigning the data model, creating geometric and thematic validation systems, matching models and importing data, connecting to subsystems, and developing client functionality. The resulting open source solution provides flexibility, scalability, and interoperability to address smart city needs.

2. Index
● Introduction
● The problem
● Migration process
● Results
● Conclusions and future work

3. Introduction
● Water management system as a strategic
element in Smart Cities
● Integration of several elements: pipes,
depuration elements, valves...
● GIS as the main system to manage elements

4. The problem
● Propietary solution for GIS
● Generic Data model
● Not all needs atended (or yes, but you must to
pay for them)
● Restrictions to connect to external systems
● Limitations for publish the information

5. Technology Stack

6. Migration process (1/9)
Design a system architecture

7. Migration process (2/9)
● Redesign data model. A custom data model is
needed to specific problems.

8. Migration process (3/9)
Create a geometric and thematic validation
system acording to the data model

9. Migration process (4/9)
Create a geometric and thematic validation system
acording the data mode

10. Migration process (5/9)
Matching between two models and import data

11. Implementing functionalities (6/9)
Connecting to several subsystems

12. Implementing functionalities (7/9)
TARDIS views

13. Implementing functionalities (7/9)
Point In Time Recovery (PITR)

15. Case Study: SmartWater (FIWARE)
(Smart City world congress, Nov. 2016)

16. Conclusions and future work
● IT solution for Smart Cities
● It is possible to make a full solution in FOSS
● Migration from propietary to FOSS. Just one
time.
● Interoperability between several systems
● Flexibility and scalability to new requirements
● DSS as next step for the system
