Deiana & Coda - input2012

  1. 1. Province of Ogliastra’s GIS services and 3D Cagliari 10/12 May 2012
  2. 2. Province of Ogliastra’s GIS services and 3D The adaptation to the Regional Landscape Plan• Province of Ogliastra is a young administration established in 2001 through enactment of a regional law by the Autonomous Region of Sardinia.• Following the entry into force, in 2006, of the Regional Landscape Plan (PPR) of the Autonomous Region of Sardinia (RAS), the Province of Ogliastra undertook the process of upgrading its Provincial Urban Plan (PUP) to the above mentioned PPR and to the Hydrogeological Plan (PAI).• 1° Phase: a large amount of data, mostly derived from the old PUP of the Province of Nuoro. Cagliari 10/12 May 2012
  3. 3. Province of Ogliastra’s GIS services and 3D The reordering of knowledge• In 2° phase, called the "reordering of knowledge", analyzes and processes of adaptation of the Provincia of Ogliastra’s PUP to PPR have been partly replaced and partly implemented by integrating into the system the large amount of information material made available by the RAS: – updated orthophotomaps; – geodatabase in scale 1:10.000; – Digital Terrain Models (DTM) and a list of different thematic maps.• A new series of territorial analysis has been produced, later used both at the provincial and at the municipal level. Cagliari 10/12 May 2012
  4. 4. Province of Ogliastra’s GIS services and 3D Support to municipalities and shared planning• In a 3° phase of "co-planning," the Planning Office of the Province of Ogliastra took then an active role in supporting of the planning offices of its inner 23 municipalities, providing: – the analysis already performed plus GIS software and hardware tools; – its experts’ technical support for the definition of all the assets covered by Regional Landscape Plan (PPR).• In parallel, the Planning Office of the Province of Ogliastra has supported the same above mentioned single municipalities’ working groups with different moments of training, followed by a targeted coaching in the ordinary working activities. Cagliari 10/12 May 2012
  5. 5. Province of Ogliastra’s GIS services and 3D Lessons learned and new opportunities• What finally emerged is the need to have an increased availability of spatial analysis tools that would allow to solve common problems, related to the territory planning, design and control activities: an increasing number of operators asking for support showed an real interest in GIS technology.• Simultaneously, the Cartographic Office of the RAS was offering a further huge amount of data produced under the new Regional Land Information System (SITR): – LIDAR datasets with relative orthophotos; – various types of high-resolution DTM, satellite imagery. Cagliari 10/12 May 2012
  6. 6. Province of Ogliastra’s GIS services and 3D 3D Web GIS 3D and SkylineGlobe technology• After about 10 years, from all this context emerges the need to have a GIS analysis tool that would give the possibility to exploit the elevation sources to have a vision of the area in three dimensions.• Thus, the adoption of a 3D GIS platform, comprehensive of a great WebGIS client/server solution, to create a photorealistic and high-performance navigator, for interactive 3D visualization and querying of spatial data.• The choice, after appropriate analysis of competing solutions, has settled over the SkylineGlobe technology. Cagliari 10/12 May 2012
  7. 7. Province of Ogliastra’s GIS services and 3D 3D base terrain creation• The production of the 3D map used as a basis for the 3D WebGIS implementation was performed in outsourcing at GeoInfoLab: this option has allowed to break down dramatically (over than one thousand percent) the costs related both to Skyline TerraBuilder’s necessary license and to the experience needed in order to obtain quickly the best result possible from the source files available.• The only file produced in a global MPT v2.0 format, in a Skyline TerraBuilder v1.7 multiprocessor environment, has reached a dimension of about 36.2 GB. Cagliari 10/12 May 2012
  8. 8. Province of Ogliastra’s GIS services and 3D Cagliari 10/12 May 2012
  9. 9. Province of Ogliastra’s GIS services and 3D 3D base terrain creation• In fact it is a result of the merging of the following different main sources: – 10 meters/pixel elevation source, made available in ESRI GRID format for all the Province of Ogliastra (about 1,52 GB); – 1 meter/pixel elevation source, made available only for coastal zones of the Province of Ogliastra in ASCII format (about 3,93 GB); – 50 centimetres/pixel image source, made available in 24 bit colour TIFF format for all the Province of Ogliastra (about 30,9 GB); – 20 centimetres/pixel image source, made available only for coastal zones of the Province of Ogliastra in colour ECW format (about 1,18 GB). Cagliari 10/12 May 2012
  10. 10. Province of Ogliastra’s GIS services and 3D 3D base terrain creation• Areas outer the Province of Ogliastra, considered less interesting for the project, have been covered by image and elevation sources with different decreasing levels of resolution: – 20 meters/pixel for elevation source of the whole Sardinia; – 300 meters/pixel for image source of the whole Italy (Sardinia included); – 1,22 kilometres/pixel for elevation source of the whole Italy (Sardinia excluded); – 4,89 kilometres/pixel for image source of the rest of the globe; – 19,57 kilometres/pixel for elevation source of the rest of the globe. Cagliari 10/12 May 2012
  11. 11. Province of Ogliastra’s GIS services and 3D Integrating and querying the information• In this phase, the environment used is Skyline TerraExplorer Pro which allows to integrate the MPT files, with the additional information of interest: – GIS layer, made available in various formats and coordinate systems (either locally or on a/the network); – scripts; – images; – audio/videos content; – 3D objects; – point clouds from laser scan acquisitions; – … Cagliari 10/12 May 2012

  13. 13. Province of Ogliastra’s GIS services and 3D Integrating and querying the information• The graphical interface includes the main 3D navigation window and the structure of all the information integrated.• Skyline TerraExplorer Pro environment allows to launch quickly and intuitively several 3D analysis (contour, slope with directions, terrain profile, best path, flood, volume, viewshed, shadow).• Other interesting tools are underground navigation, interfacing GPS devices via NMEA protocol, network sharing of collaborative sessions, pipe and power line tools, audio/video feeds integration, 3D object import and urban design. Cagliari 10/12 May 2012

  15. 15. Province of Ogliastra’s GIS services and 3D Integrating and querying the information• Once operator has finished the integration of information, he can save the project in the proprietary FLY format.• This stores all the information (paths and properties) related to all the resources involved (MPT file, GIS layers and other sources), and can then be used to create digital media kits or to publish 3D WebGIS projects on the Internet.• Anyone can freely download and install the Skyline TerraExplorer Viewer application, in order to access and query the so published projects and all the information there integrated. Cagliari 10/12 May 2012
  16. 16. Province of Ogliastra’s GIS services and 3D Streaming the 3D terrain• Given the considerable size of the 3D terrain, the navigation through the Internet requires an application server able to deliver this information seamless in streaming: the Skyline TerraGate streaming server.• A Skyline TerraGate license supporting up to 25 concurrent connections let the various TerraExplorer clients (Pro Plus or Viewer) query simultaneously different portions of the MPT.• For each streaming session, the TerraGate Manager records: client IP address, date and start time of the session, its duration and total volume of data provided. Cagliari 10/12 May 2012
  17. 17. Province of Ogliastra’s GIS services and 3D Streaming the layers• A further saving of money comes for the delivery of layers, a task accomplished by GeoServer, an open-source certified OGC compliant server solution.• The vector layers are loaded on the server disk space in the Shapefile format, and then uploaded and managed by GeoServer server application, which delivers them on-demand via WFS protocol. The published FLY project include information for the directly loading from GeoServer.• Implementation of raster layers’ streaming through WMS protocol, always via GeoServer, is expected in a next phase. Cagliari 10/12 May 2012
  18. 18. Province of Ogliastra’s GIS services and 3D Potential of the 3D WebGIS by Skyline• The possibilities offered by the use of 3D WebGIS by Skyline are truly remarkable. The main fields of application and interest for the Province of Ogliastra ranging from land and environmental planning, to tourism and cultural promotion, from civil defense and safety, to transport services and infrastructures.• The Planning Office of the Province of Ogliastra is preparing new updated geodatasets on a provincial scale, containing information relating to the Provincial Coordination Territorial Plan, the Provincial Transport Plan, the Provincial Energy Plan, the Civil Protection Plan, the Wildlife and Hunting Plan, .... Cagliari 10/12 May 2012
  19. 19. Province of Ogliastra’s GIS services and 3D Enhancement and promotion of local trails• In higher detail, the use of this 3D WebGIS platform is currently being studied within the project called "routes" managed by GAL Ogliastra. This project involves the same Province of Ogliastra, as leader, and all its 23 municipalities, in the development of a provincial network of routes, with particular emphasis on the enhancement of the local paths’ network.• The application designed will have to publish and promote in the 3D WebGIS platform the itineraries and paths, which will also be available for the download in formats used for GPS devices, iPhones and Android mobile platform.
