TL;DR: To provide a reliable end product to farmers, advances in platform design, production, standardization of image georeferencing and mosaicing, and information extraction workflow are required and the farmer should involve in the process of field design, image acquisition, image interpretation and analysis.

TL;DR: Wang et al. as discussed by the authors summarized landscape studies of karst landscapes patterns, their dynamics and interactions among landscape pattern, hydrological processes and ecosystem services (ES), and conducted a systematic literature review to identify knowledge gaps and recommend future research and policy directions.

TL;DR: In this article, the authors investigated the spatiotemporal variations in vegetation cover using a Normal Difference Vegetation Index (NDVI) time-series data set obtained from Moderate Resolution Imaging Spectroradiometer (MODIS) and climate data from 2000 to 2010.

TL;DR: A remote sensing based approach to evaluate the long-term efforts of the ERPs started in 2000 was proposed, and counties with high project effectiveness in spite of complex natural conditions were identified, while counties with negative vegetation trends despite relatively favorable conditions and high investments were also distinguished.

TL;DR: Wang et al. as discussed by the authors used three Landsat Thematic Mapper images from 1990, 2004, and 2011 to examine whether various image pre-processing methods (vegetation indices, topographic correction, and minimum noise fraction [MNF] transformation) and a digital elevation model improved image classification.
