Databases and GIS Technologies

The works on creation GIS were carried out in 1999-2000 yy. in Olyekminsky reserve. At the first stage the topographical basis GIS of Olyekminsky reserve, realized in two program environments basing various models of cartographical performance - ArcView (vector model) and IDRISI (rastr model) was made. In 2000 the thematic layers of vegetation and geology of reserve are created. The performance of this task became possible due to presence in reserve of maps landscape, vegetation, soils, geological, made in the beginning 90 years on a paper basis. 

Similar minimal set of thematic layers: a hydrology, relief, vegetation, geology allow the employees of reserve to decide all variety of tasks under the analysis of long-term numbers of the data saved on the program of background monitoring in reserve for all period of supervision with 1985 on 2001 yy. 

The software package ArcView enables integration of databases created for plants, animal, soils etc. with GIS. Any card of primary supervision with exact description of coordinates, can be submitted as a point on a thematic layer of GIS. It can be also results " of the tracks accounts ", "air account", the results of the geobotanical, soil, hydrochemical, geochemical, hydrobiological descriptions etc. Now are created thematic layers on rare plants of reserve, including on the plants which have been brought in to the Red Book of Russian Federation. The layers with results of the air accounts of hoofed animals are created. 

Besides with the help of the “hot connection tool " is possible to connect with the chosen point on a thematic layer any information: a video, photo, sound, textual, devoted to the given object of research. 

At last, with GIS it is possible to look after not only spatial heterogeneity of distribution of plants, animal, but also to define, how the ways of seasonal migration of animals, the area distribution of plants and animal change in time. It is reached by imposing the layers created for each chosen interval of time against each other. At such "step-by-step" performance of results the change of the spatial characteristics of object for this or that interval of time is evidently visible. The size " of a temporary step " gets out by researcher. 

Thus, with the help of the GIS- projects it is possible to unit and to systematize all kinds of the information, which is saved in reserve at realization of the program of background ecological monitoring: databases, texts, photos, figures, videomaterials and sound files.
