Landsat 8, a NASA and USGS collaboration, acquires global moderate-resolution measurements of the Earth's terrestrial polar regions in visible, near-infrared, short wave, thermal infrared. 8 extends remarkable 40 year record has enhanced capabilities including new spectral bands blue cirrus cloud-detection portion spectrum, two bands, improved sensor signal-to-noise performance associated improvements radiometric resolution, an duty cycle that allows collection significantly greater number...
Formal planning and development of what became the first Landsat satellite commenced over 50 years ago in 1967. Now, having collected earth observation data for well four decades since 1972 launch Landsat-1, program is increasingly complex vibrant. Critical programmatic elements are ensuring continuity high quality measurements scientific operational investigations, including ground systems, acquisition planning, archiving management, provision analysis ready products.

Abstract Cover crops have critical significance for agroecosystem sustainability and long been promoted in the U.S. Midwest. Knowledge of cover cropping variations impacts government policies remains very limited. We developed an accurate cost‐effective approach utilizing satellite fusion data, environmental variables, machine learning to quantify corn soybean fields from 2000 2021 found that crop adoption most counties was stagnant 2011, but has significantly increased 2011 2021. The is...
Cover crops have critical significance for agroecosystem sustainability and been long promoted in the U.S. Midwest. Knowledge of variations cover cropping impacts government policies remains very limited. We developed an accurate cost-effective approach utilizing multi-source satellite fusion data, environmental variables, machine learning to quantify corn soybean fields from 2000 2021 found that crop adoption most counties has significantly increased recent 11 years 2011 2021.

This work investigates the spatial dynamics currently at in Missouri hog production industry with regard to confined animal feeding operations (CAFOs). Through a quantitative analysis of enterprise size and an interpretation legal social pressures area, clustering facilities within is examined. State legislation was found influence various sizes CAFOs how they cluster. As whole, largest were be most influenced due their heavily restricted geography while smaller less by state laws. Cette...
Reflectance measurements of crop plants and canopies show promise for guiding within-season, variable-rate nitrogen (N) application. Most research results have been obtained around solar noon with clear skies. However, practical application, the system must work under cloudy skies or away from noon. The objective this was to assess effect cloud conditions on reflectance a corn canopy. approach estimate an instantaneous sky clearness index (ICI) which could be used correct field radiometer...
A long-term growth analysis was conducted for the City of Springfield, Missouri. The Springfield Department Planning and Development interested in determining characteristics patterns urban within metropolitan area over past three decades. interest assessing development trends region stems from present day environmental problems areas recently annexed or that have undergone intensive development. myriad exist if city continues to grow as expected (a fifty percent increase next 20 years)....
The development of an integrated digitizing and display surface, which utilizes touch entry flat panel (FPD) technology, is a significant hardware advance in the field geographic information systems (GIS). Inherent qualities FPD, notably ac gas plasma display, makes such marriage inevitable. Large diagonal sizes, high resolution color, screen flatness, monitor thickness are desirable features surface. Recently, GIS literature has addressed need for innovation. graphics displays based on...
