2 ISO 9001:2008 Certified Quality System ABACO srl C.so Umberto I, Mantova, Italy tel. +39 (0) fax +39 (0) Abaco is active since 1990 in the R&D of edge technologies that can be now applied to IACS solutions. In addition to the usual LPIS information, we have now solutions to take advantage of 3D data captured with different acquisition technologies. 15 th GeoCAP conference Taormina (Sicily) IT November 18 20, 2009

3 3D GOAL Understanding reality More measuring tools Improve controls using 3D

4 DTM It is useful to obtain land information, apply measuring tools and for 3D viewing.

5 DTM It is useful to obtain land information, apply measuring tools and for 3D viewing.

6 LiDAR & SAR Vegetations Models They are useful to obtain land information and to apply measuring tools. Not easy to be used due to the huge quantity of data.

32 DbMAP Web 3D Flyers finding models

33 Benefits with 3D Some examples Finding disadvantaged land parcels (ex. LFA); Seeing rural developments through feedback of inspectors; Determining quality parameters of vineyards production (ex. for certifications); Feedback for checking the crop plans (unlikely crops).

34 3D technological requirements Enhanced LPIS Based on centralized spatial enabled RDBMS Compliant with OGC Services Ability to manage large scale spatial datasets including high detail 3D terrain models Information mining Full accessibility to 3D data attributes, visual querying tools Web based 3D tools for visualization and use Visualization and measurements of terrain, urban and rural data. Authoring tools to create/update 3D models Ex. tools for automated extraction of 3D features (like buildings, façades, etc.)

35 DataBase - 3D data types For example, Oracle Spatial supports natively the following 3D data types: SDO_TIN SDO_GEOMETRY SDO_PC
