an important factor in sustainable agriculture and economic management is to calculate areas under different crops that the inputs of agriculture connect to this topic. planning of agricultural mechanization, fertilizer and pesticide requirements, pests and diseases control, estimates of agricultural production, income and tax and financial planning, all linked to the cultivated areas and estim...

In monitoring vegetation change and urban planning, the measure and the mapping of the green vegetation over the Earth play an important role. The normalized difference vegetation index (NDVI) is the most popular approach to generate vegetation maps for remote sensing imagery. Unfortunately, the NDVI generates low-resolution vegetation maps. Highresolution imagery, such as IKONOS imagery, can b...

Mapping and monitoring of vast coastal wetlands vulnerable to dynamic coastal erosion, sea-level rise, fire, and marsh succession require remote sensing approaches that capitalize on newly available sensors, advanced classification techniques, and combinations of multi-sensor and multi-date data. This pilot study assesses the feasibility and accuracy potential for mapping specific coastal wetla...

Aims Biodiversity is traditionally studied mostly at the species level, but biogeographical and macroecological studies higher taxonomic levels can provide valuable insights into evolutionary processes large spatial scales. Our aim was to assess representation of vascular plant families within different vegetation formations across Europe. Location Methods We used a data set 816,005 plots from ...
