TL;DR: In this article, three supervised classification algorithms namely Maximum Likelihood (MXL), Artificial Neural Network (ANN) and Support Vector Machine (SVM) were evaluated and compared using very high resolution WorldView-2 satellite imagery for vegetation type/land cover (VT/LC) mapping in Keoladeo National Park (KNP), India.
Abstract: The present study evaluates and compares performance of three supervised classification algorithms namely Maximum Likelihood (MXL), Artificial Neural Network (ANN) and Support Vector Machine (SVM), using very high resolution WorldView-2 satellite imagery for vegetation type/land cover (VT/LC) mapping in Keoladeo National Park (KNP), India. We mapped 16 (8 gregarious VT and 8 LC) classes, and used Bootstrap (with 100 iterations) method for accuracy assessment. All three algorithms produced high overall accuracy (OA) (67–85%) and kappa (K) (65–83) values. Visual comparison of the predictions revealed that SVM (OA = 85.12% (K = 83.9) with 3.85% width of confidence interval) performed the best followed by ANN (69.72% (67.32) with 4.43%) and MXL (67.37% (65.22) with 4.33%). This research provides insight for selection of classification algorithm for detailed VT/LC mapping of wetland associated systems using very high resolution satellite data. The findings of this research are useful for environmental management, restoration and conservation planning of KNP, India. The database will be of high value for future development and sustainability issues in the park.

TL;DR: In this paper, a method has been developed for quantitative measurement of vegetation conditions over broad regions using ERTS-1 spectral bands 5 and 7, corrected for sun angle, which is shown to be correlated with aboveground green biomass on rangelands.
Abstract: The Great Plains Corridor rangeland project utilizes natural vegetation systems as phenological indicators of seasonal development and climatic effects upon regional growth conditions. A method has been developed for quantitative measurement of vegetation conditions over broad regions using ERTS-1 MSS data. Radiance values recorded in ERTS-1 spectral bands 5 and 7, corrected for sun angle, are used to compute a band ratio parameter which is shown to be correlated with aboveground green biomass on rangelands.

TL;DR: Introductory Digital Image Processing: A Remote Sensing Perspective focuses on digital image processing of aircraft- and satellite-derived, remotely sensed data for Earth resource management applications.
Abstract: For junior/graduate-level courses in Remote Sensing in Geography, Geology, Forestry, and Biology. Introductory Digital Image Processing: A Remote Sensing Perspective focuses on digital image processing of aircraft- and satellite-derived, remotely sensed data for Earth resource management applications. Extensively illustrated, it explains how to extract biophysical information from remote sensor data for almost all multidisciplinary land-based environmental projects. Part of the Pearson Series Geographic Information Science. Now in full color, the Fourth Edition provides up-to-date information on analytical methods used to analyze digital remote sensing data. Each chapter contains a substantive reference list that can be used by students and scientists as a starting place for their digital image processing project or research. A new appendix provides sources of imagery and other geospatial information.

TL;DR: In the early stages of economic development, economic development is characterized by urbanization, where the population moves through migration from an agricultural, rural based existence to one where production occurs in cities of endogenous numbers and size.
Abstract: This chapter on urbanization and growth focuses on modeling and empirical evidence that pertain to a number of inter-related questions. Why do cities form in an economy, with so much of economic activity in countries geographically concentrated in cities? Second, how do different types of cities interact with each other in terms of trade and migration? Given the answers to these questions the chapter turns to growth issues. How does a system of cities evolve under economic and population growth; and how does urban growth intersect with, or even define national economic growth? In growth theory, endogenous growth is based on knowledge spillovers and sharing, and evidence suggests that much of that interaction must occur at the level of individual cities. In the early stages of growth, economic development is characterized by urbanization – a spatial transformation of the economy, where the population moves through migration from an agricultural, rural based existence to one where production occurs in cities of endogenous numbers and size. How do we model that transformation process and what are the key aspects of the transformation? In any static, growth, or development–urbanization context, how do governance, institutions, and public policy affect city formation and sizes, which then in turn affect economic efficiency. Cities require enormous public infrastructure investments which affect urban quality of life, in particular health and safety and commuting and congestion costs. Institutions governing land markets, property rights, local government autonomy, and local financing affect the city formation process and city sizes. And national government policies concerning trade, labor policies and national investment in communications and transport infrastructure affect the shape of the urban system. A final set of questions has to do with where cities locate. What is the effect of history, of climate and of natural resource locations, including rivers and natural harbors, on the location of current urban agglomerations?
