## Current behavior

The agent (person or entity) must write the location of the incident, but following the implementation that will be done for closing issue #68 , writting latitude and longitude can be problematic.

## Expected behavior

What would be perfect is: the person or the entity, can click on a google maps' map the location of the incident. The latitude and longitude will be stored and sent in the incident's location. (always following the format explained in #68 )

## What is the motivation / use case for changing the behavior?

An easier behaviour of the aplication and the incident creation for the agent creating the report (the incident)

Others:

Remember taht, the sensor will send it's own location, so the location selection won't be necessary.

Start by reading issue #68 and the incident-submission flow. Determine where the agent enters an incident location and how location data is stored and sent. Done means the agent can select a location on a Google Maps map, with latitude and longitude sent in the format required by #68, while sensor-provided locations do not require selection.
