WAYS TO ACHIEVING A SPATIAL INFORMATION SYSTEM (SIS) FOR THE FORESTRY SECTOR BY USING OF MAPSYS 8.0 PROGRAMME PUBLISHEDLaura Vasilica Damian, Cristian Ghiţă Crainic
The design of spatial information system represents nowadays an issue for a series of sectors of practical application fields where some spatial data linked to the activities deployed are being used. As a consequence, in the case of forestry sector, the implementation of the information sector is imperiously required taking into account the specificity of the deployed activities. Modern positioning technologies of different characteristic points as well as the cartographic products in digital format provides for a complex and differentiated exploiting of the data collected in this manner. The use of ortho-photographic plan in forestry sector represents a mean of collecting data (the so-called raster data) which are very important for the characteristics of deployed activities. Moreover, the forestry maps and forest arrangements can provide important information as regards the stand (forests) specificity required in growing stock’s careful management activities. The design of a complex database requires that field data be accurate and mirrors the objective reality on the ground. Achieving this goal supposes input data checking within the IT system, on the ground, while the potential shortcomings will be adjusted accordingly. Data processing in order to complete the design of the information systems require the use of some very specialised and dedicated software which will accomplish the specific points’ spatial positioning and reporting, as well as the data base completion. The study case carried out within the Siniob U.P.I., Sacuieni Forest Range Canton, Bihor County Forestry Directorate. For the study case was used the MapSys 8.0 programme. The data were collected from the ortho-photographic plan; some completions of these data being made within the parcels where forestry works were performed starting from the ortho-photographic plan design and up to present. Some particular issues were identified when the growing stock limits were set, especially for the areas where vegetation lives outside the growing stock while the separation of the above-mentioned parcels raise some problems. The solving of these problems involves visits paid on the spot and the stands’ separation; in this later case the limit points being set previously by the combined use of GNSS-TS technology. Following to the data accurate processing, digital products are generated, namely the thematic maps and alphanumeric data in tabular format out of which they can be exported to different working formats, if necessary. The spatial information systems are very useful products for forestry sector, being characterised by a high technical resilience, and providing useful information for different managerial, technical solutions etc., necessary to be adopted.
