2. Service Specifications
The ROMEO service provides two type of information on Rome territory for a selected user (Province of Rome Local Authority):
Maps of new buildings.
Maps of burned areas.

3. Service Specifications
The user can select the specific region where he is interested in detecting the fire scars and/or new urban areas.
The user can select a year of interest in detecting the fire scars and/or new urban areas.
Most of the work for the production of the maps will be made off line using a neural network algorithm.
The service provide change maps starting from year 2000, with a temporal resolution of 1 year.
The spatial resolution for fire scars is 30 meters (Landsat).
The spatial resolution for new buildings is up to 1 meter (Orthophotos).

4. Burned Areas Maps
The maps of burned areas was made using a neural network algorithm applied on a landsat image
6 bands.
NDVI.
Multiple updates per year.

5. Burned Areas Maps
The maps of burned areas was made using a neural network algorithm applied on a landsat image.

6. Burned Areas Maps
The maps of burned areas was made using a neural network algorithm applied on a landsat image.

7. Burned Areas Maps
The maps of burned areas was made using a neural network algorithm applied on a landsat image.

8. New Buildings Maps
To detect the new buildings, a comparison between two soil sealing maps, obtained by the use of a neural network algorithm applied on a landsat image, was used.
Sealed surfaces
Unsealed surfaces

11. New Buildings Maps
The sealing maps need to be refined by human interaction using hortophotos, to idintify the buildings not detected by the NN algorithm.

12. New Buildings and Fire Scars
For each year, two different multi-polygon shapefiles are produced, each polygon has the following information:
Type of surface (New building / fire scar)
Year
Month
Perimeter
Area

13. ESA services portal server
Service Integration
Integration of the service process inside the SSE environment:
GEO-K server
Client
ESA services portal server
Toolbox 7.0
Apache
Tomcat
Web Server
(WMS - IIS)
GEO-K database

14. GEO-K Web Features Server (WFS)
Service Integration
The main requirements for the Web Feature Service are:
1. The interfaces is defined in XML.
2. GML is used to express features within the interface.
3. The datastore used to store geographic features is opaque to client applications and their only view of the data is through the WFS interface.
Client via SSE Portal
GEO-K Web Features Server (WFS)

15. Service Access Request

Service Access Request

16. Service Description Select type of map (buildings, fire scars, both)
Select the years of interest
Select a maximum/minimum area or perimeter of the polygons
Draw an area of interest
Download the selected features of one layer or both, in shapefile format
Export in KML, GeoTIFF, PDF

17. Final comments
Experience with SSE:
The system is suitable for providing this kind of services
Good system stability
Extend the accessibility to other Web Browsers.
Documentation should be updated.
Expectations:
Extend the service from a test area to the whole province of Rome.
Offer the service to new local Administrations
