Journal ArticleDOI
TL;DR: In this paper, pixel-based and object-based image analysis approaches for classifying broad land cover classes over agricultural landscapes are compared using three supervised machine learning algorithms: decision tree (DT), random forest (RF), and the support vector machine (SVM).

785 citations


Journal ArticleDOI
TL;DR: The Landsat Data Continuity Mission (LDCM) as mentioned in this paper is a successor to the Landsat data continuity mission (LDSM) that will collect, archive, and distribute the image data as part of the Earth Resources Observation and Science (EROS) archive.

Journal ArticleDOI
TL;DR: In this article, the remote detection of water stress in a citrus orchard was investigated using leaf-level measurements of chlorophyll fluorescence and Photochemical Reflectance Index (PRI) data, seasonal time-series of crown tem- perature and PRI, and high-resolution airborne imagery.

Journal ArticleDOI
TL;DR: In this article, the authors presented an approach for combining four passive microwave products from the VU University Amsterdam/National Aeronautics and Space Administration and two active microwave items from the Vienna University of Technology.

Journal ArticleDOI
TL;DR: In this article, the authors evaluated the accuracy of the GIMMS3g data by comparison with the global Terra MODIS NDVI (MOD13C2 Collection 5) data using linear regression trend analysis.

Journal ArticleDOI
TL;DR: In this article, the authors present the case for using Lidar sampling as a means to enable timely and robust large-area characterizations, and discuss the potential of using lidar in an integrated sampling framework for large area ecosystem characterization and monitoring.

Journal ArticleDOI
TL;DR: In this paper, the authors provided an analysis of trends in vegetation greenness of semi-arid areas using AVHRR GIMMS from 1981 to 2007, and found that greenness increases are found both in semi-arsid areas where precipitation is the dominating limiting factor for plant production (0.019 NDVI units) and in semiarid regions where air temperature is the primarily growth constraint (0.,013 NDVI Units).

Journal ArticleDOI
TL;DR: In this article, the utility of moderate-resolution thermal satellite imagery in water resource management is explored, including methods developed to safeguard evapotranspiration (ET) estimates from expected errors in the remote sensing inputs.

Journal ArticleDOI
TL;DR: Sentinel-3 as mentioned in this paper is an Earth observation satellite mission specifically designed for Global Monitoring for Environment and Security (GMES) to ensure the long-term collection and operational delivery of high-quality measurements to GMES ocean, land, and atmospheric services, while contributing to the emergency and security services.

Journal ArticleDOI
TL;DR: In this article, a random forest classifier was applied to spectral as well as mono- and multi-seasonal textural features extracted from Landsat TM imagery to increase the accuracy of land cover classification over a complex Mediterranean landscape.

Journal ArticleDOI
TL;DR: In this article, a multi-purpose time-series-based disturbance detection approach is proposed to identify and model stable historical variation to enable change detection within newly acquired data, which can analyse in-situ or satellite data time series of biophysical indicators from local to global scale since it is fast, does not depend on thresholds and does not require time series gap filling.

Journal ArticleDOI
TL;DR: In this paper, a multispectral expert system used a neural network approach to provide Rapid Response thickness class maps using a spectral library approach based on the shape and depth of near infrared spectral absorption features.
