Content • Who is R3 GIS? • Why a Green Area Management System? • Geodatabase and Data model • Jobs, inspections, workflows • Citizen information • Conclusions
Founded 2003 Main office in Merano (BZ), second office in Milano 12 Collaborators, (6 in software development) Quality Certification ISO 9001:2008 Member of the Open Geospatial Consortium Funding member of the Foss Academy Operating through partners in Italy, Austria and Germany
Activities SOFTWARE DEVELOPMENT ACTIVITIES CONSULTING PROJECTS TRAINING SERVICES TOURISM AND SKI AREAS PUBLIC ADMINISTRATION GREEN AREA MANAGEMENT UTILITIES ENVIRONMENT AND AGRICULTURE FOSS ACADEMY SECTORS
Open Source Technology • CentOS or RedHat operating system • Geodatabase PostgreSQL/PostGIS • PHP, Java, Javascript, HTML • UMN Mapserver/GeoServer • Analysis: Grass, jGrass, gvSIG, uDig, QGis • WebGIS Client: OpenLayers, GisClient R3 GIS contributes to most of these Technologies
Management of urban green areas • Public parks and gardens • Private gardens • Cemeteries • Tree-lined streets • Transport corridors with trees and vegetation • River-bank corridors with trees and vegetation
Why a Green Area management software? • Documentation in the case of damages • Planning and accounting for maintenance activities • Reporting, statistical analysis • Quality control and improvement
Why a WebGIS? All users access one central database An authentication system enforces security Access by all stakeholders involved Privileges are set according to responsibilities Access in the field on a tablet or PDA

Data Model requirements • Flexibility (type of managed assets must be configurable) • Hierarchical structure (allows different levels of abstraction) • Compatibility to national standards (National data core, Inspire) • Applicability to different maintenance jobs (each type of job requires different tools, expertise, machines and has a different price)
VEGETATION STREET FURNITURE MANAGEMENT Data model structure
Data model example CITY GEODATABASE GREEN AREA DATA MODEL VEGETATIONURBAN GREENGREEN AREA FLAT LAWN A101016 LAWN WITH CONCRETE BLOCKS A101050 LAWN LAWN IN ESCARPMENT A101051 LAWN IN TRAM LINE A101052 Assets are classified according to the type of maintenance activities they are subject to. This allows for accurate maintenance cost calculations and stimulates update of geometries.
Map Interface • WebGIS interface with standard GIS tools • Based on OGC Standards • Multilingual • Simple geometry editing tools • Print functions in different sizes and formats • Google Street View integrated • Interactive selection, query and Tooltip tools • Editing tools with snapping capability • Legend and hierarchical layer tree • Measuring tools
Data entry Import-Export Tools: checks integrity and topology, stores historical information Editing tools allow entry and management of geometry and attributes directly from the map interface

Workflows managed: a view examples • TREES: tree database with main characteristics of each plant. Workflows for planting and felling trees and for removing the stump. • VTA: visual and instrumental tree assessments, documentation, traceability • PLAYS: Playgrounds, equipment and periodical inspections. Management of maintenance activities. • GREEN AREAS: GIS inventory of all objects, statistics, historical information. • JOBS: planning, monitoring and documentation of maintenance activities, directly linked to the assets involved • QUALITY: tools to ensure monitoring and action to ensure quality of public areas
Example: Visual TreeAssessment (VTA) Each tree is subject to periodic assessment to ensure public safety and quality of urban green spaces
Example: Visual Tree Assessment (VTA) Visual Assessment Instrumental Analysis
Job programming and follow-up Job, Operator, time of execution, cost, etc. are connected to actual asset on the ground. historical database • Programming of maintenance activities • Quantities are provided by the GIS • Cost is calculated based on quantities • The job is programmed in a certain time period • Closing activities as they are carried out

Quality control • Non compliances are recorded in the field through Trimble Juno PDAs with Position, photo and attributes. • Synchronisation transfers all data to the server, where it is combined with the GIS and checked against open jobs and previous non-compliances • After checks a job is created and assigned to the contractor responsible for the site

Publication on the web • Main data are made available to the public • Each change in the management application is automatically applied to the public interface • Public interface is very simple and user friendly • Examples: • Merano (www.ambiente.comune.merano.bz.it) • Rimini (http://www.antheasit.it/public)
Who uses R3 TREES? Municipalities: About 35 cities in Italy including Milano, Pavia, Forli, Sanremo, Rimini, … Transport companies: Highway Milano-Genova, Tangenziali di Milano, Ferrovie Nord Institutions managing housing estates: Provinces, Insurance companies, Cooperatives Contractors for green area management.
Conclusions A well organised GIS of urban green areas can: • Allow you to share all relevant information with all stakeholders • Document all activities and thus take decisions based on data and gives legal security in case of accidents • Improve management activities by learning from past experience • Ensure save and enjoyable parks and recreation areas in your town.
