**3. PERMANENT DATA UPDATE** **A permanent data update allows forecasting of increasing and decreasing forestry areas depending on the natural causes and disasters and human activity.** 
**4. DETAILED MAPPING OF FORESTRY AREAS** Detailed mapping of forestry areas based on satellite images of 0.5m-2m resolution can be used for various purposes: - Control of valuable trees growth; - Prediction of floods impact and consequences; - Control of fire safety and forecast of damages; - Other. *Vegetation detection featuring the clustered vegetation and classification by types (foliar, coniferous, mixed, unique tree species):*   
**5. VEGETATION DETECTION IN URBAN AND SUBURBAN AREAS** This method implies to use the most accurate images of 0.3-1m resolution and is applicable in vegetation detection within city areas: parks, forested parks, gardens, square parks. For each detected parcel, the area is calculated (including bushes, lawns). In addition, the output data can be presented as a detailed map where the trees (up to every single separate tree) can be detected based on the images of high resolution only (HR resolution satellite images). In its turn, it will give a possibility for: - Registration of vegetation unit, even to within 1 tree; - Accurate mapping of vegetation; - Maintenance of various environment-oriented DBs (e.g. [the DB of the oldest trees][1] ) - Assessment of the state of the vegetation.
