Find on the Google Maps 25 closest airport on European continent from the desired location, in a radius of 250, 500, 1.000 or 10.000 kilometers. Type the desired location in the form of the city name (for example: Barcelona ) or a full address (for example: Carre de Pons i Gallarza 11, Barcelona).
After processing the results you get in the left column : name of the airport , distance from the defined location expressed in kilometers , city and state in which the airport is located. Requested locations will be displayed on the Google Maps in the markers form.

Application of USLE, GIS, and Remote Sensing in the Assessment of Soil Erosion Rates in Southeastern Serbia

Polish Journal of Environmental Studies

The assessment of soil erosion rate and its spatial distribution in the hilly-mountainous Nisava River basin was conducted by Universal Soil Loss Equation (USLE) model through a GIS-based approach. A Landsat 7 Enhanced Thematic Mapper (ETM+) image and normalized difference vegetation index (NDVI) were used for the determination of crop management factor. The average annual soil loss was estimated at 13.1 t·ha-1·yr-1, classifying the Nisava River basin under the high erosion rate category. Abou

Spatial modelling of soil erosion potential in a mountainous watershed of South-eastern Serbia

Springer

This work aims at the assessment of soil erosion rate and its spatial distribution in hilly mountainous Nisava River Basin (South-eastern Serbia) with a surface area of approximately 2,848 km2. The study was conducted using Universal Soil Loss Equation (USLE) model due to its modest data demand and easy comprehensible structure. The erosion factors of USLE were collected and processed through a GIS-based approach. Landsat 7 Enhanced Thematic Mapper (ETM+) image and normalized difference vegetation index (ND
