摘要：The town of Racconigi is located in the north west of Italy, about thirty kilometers south of Turin. The Royal Park and Castle are part of the so-called system of "corone di delizie" (crowns of delights), a group of royal residences that surrounds Turin, the former capital city of the first Savoy Kingdom and later Italy. These residences have recently been included in the world heritage list by UNESCO (1997); in recent times the site has become a remarkable centre of cultural activities and events. The Park is rich in wildlife and lush vegetation, and, starting from the beginning of the twentieth century, it was left to run wild, because of high maintenance costs. Therefore, to face an overall decay, which became more significant after the Second World War, extensive recovery and restoration projects were required to bring the Park back to its original glory. The Architecture and Landscape Safeguard Office in Piedmont, which manages the site, started an important restoration project: the first phase consisted in the collection of reliable geometric knowledge, which was lacking, therefore the DITAG Geomatics research Group at the Politecnico di Torino was involved in creating a stable Reference Network and updated cartographic supports. The hydraulic system in the park has been completely replanned and restored over the last three years. Now attention is focused on the rich botanical property of the Royal Park, which is 170 hectares wide (about 430 acres), with an 18 hectare lake (about 45 acres) and about 25 Km of paths. A group of botanists carried out a complete census of the trees approximately twenty years ago, with the goal of preparing a botanical classification of the species and of examining their state of health. All the data was collected in a paper archive and their position mapped on a paper support; the survey output is now difficult to access or manage, and it needs to be updated. For a modern management of the site, all the data needs to be translated into a digital format. An appropriate information system is of primary importance. As the park is going to be opened to the public, it is so important to identify dangerous situations in order to guarantee the safety of the visitors. The system has to collect all available site data (historic plans, archive resources, specialists census, topographic surveys…), in order to have a complete overview of the situation; the system has to help in the ordinary maintenance operations of the trees (e.g. pruning, planting and the felling of the trees), and to keep the database updated, recording changes and variations. To guarantee these operations a support management system which is based on a web architecture in order to offer flexible usage, both in the data collection phase and in the system fruition has been created. An appropriate data structure was considered in a GIS environment, aimed at collecting the survey data, storing the historical information from previous sources and making the link to its position evident. The system is completely based on Open Source tools, in order to build a flexible and scalable architecture. This choice is also in tune with the policy of the Safeguard Office, which has the aim of developing a set of Open solutions that can be used to replicate in all the properties it manages. This database stores multi-temporal spatial data and its structure is described in the paper
