• Seldom destructive (hail, tornado, flash floods)

• Rapid evolution (~ 1 h)• Small scales (~10km)• Limited predictability

CROWDSOURCING!CROWDSOURCING!


• Free and open source software (LGPL) for information collection, visualization, and interactive mapping

• Sending information via web or smart-phone by Android (and maybe iOS apps...)

• Storage of data on MySQL “flat” database: data are then mapped as JSON

• Structured as a CMS• Customization of the application depending on your

needs• Attaching photos, videos, files, or links to other news• Anyone could post information → Crowdsourcing


• Current version: v3 → not tested yethttps://github.com/ushahidi/platform

• Used version: v2.7.4https://github.com/ushahidi/Ushahidi_Web

→ Basic requirements:- Php 5.2.3 or greater (>5.3 recommended)- MySQL version >5.0- HTTP Server (of course…)• Online resource to test functionality on your own

map: https://crowdmap.com


Ushahidi experience

• Snow surveys from 2012: - 580 snow surveys by “authorized” users on

four locations in the Alps- more than 30 avalanches reported- in total more than 2,100 reports collected

• Localization of the survey based on station code• Insertion on MySql DB• Automatic publication of the report

Ushahidi: Pros

• Simple zipped folder, need only web and DB installation → ready in about 1 hour

• Free plugins to extend capabilities• Basic customization: some options accessible

for a basic IT skill user• Adding users• Validating and confirm the information collected• Designing different forms to collect information• Adding categories to map• Choosing base layer• Creating triggers (email alert for new reports)


Ushahidi: Cons

• Few guides for developers• Lacks on mobile interface• Bugs (mostly on DB management)• DB MySQL, preferable PostgreSQL → new

feature in v3 but not tested yet• Advanced customization: for nerdy people

only!• Adding custom base layer• Create new theme (CSS styling)• Modify DB behavior• Create complex trigger actions• Manage DB and code bugs


Final considerations

For basic functionality, Ushahidi does greatly its job.

But if you need a system with advanced features, greater customization, a flexible tool that can also help in complex work situations, it is better to develop your own project allowing more freedom of action (for example using Drupal or other complex CMF)

However the version 3 perhaps has introduced new useful features...


Lesson learned• Strength:

– Costs reduction– Easy and rapid

development– Huge help by www

• Weakness: – Too frequent updates– Dead OS projects– New releases compatibility– Initial choices very hard


Near future?• Innovative sensors• Networking &

Communication• Cloud computing• Crowdsourcing

– Citizens as sensors– Collaborative

frameworks• Big data paradigm

ESONDA, Ferrara, 21-23 settembre 2016


Ongoing works

• Data fusion (ground obs, EO, social media)• Improving Nowcasting• Extending Early warnings• Increasing web-services

– WMS / WFS / WMST services– GeoJSON– Webapps
