A Remote Sensing Driven Geospatial Approach To Regional Crop Growth And Yield Modeling, Sadia Alam Shammi
A Remote Sensing Driven Geospatial Approach To Regional Crop Growth And Yield Modeling, Sadia Alam Shammi
Theses and Dissertations
Agriculture and food security are interlinked. New technologies and instruments are making the agricultural system easy to operate and increasing the food production. Remote sensing technology is widely used as a non-destructive method for crop growth monitoring, climate analysis, and forecasting crop yield. The objectives of this study are to (1) monitor crop growth remotely, (2) identify climate impacts on crop yield, and (3) forecasting crop yield. This study proposed methods to improve crop growth monitoring and yield predictions by using remote sensing technology. In this study, we developed crop vegetative growth metrics (VGM) from the MODIS (Moderate Resolution Imaging …
Assessment Of Great Basin Bristlecone Pine (Pinus Longaevaâ D.K. Bailey) Forest Communities Using Geospatial Technologies, David Richard Burchfield
Assessment Of Great Basin Bristlecone Pine (Pinus Longaevaâ D.K. Bailey) Forest Communities Using Geospatial Technologies, David Richard Burchfield
Theses and Dissertations
Great Basin bristlecone pine (Pinus longaeva D.K. Bailey) is a keystone species of the subalpine forest in the Great Basin and western Colorado Plateau ecoregions in Utah, Nevada, and California. Bristlecone pine is also the world's longest-lived non-clonal organism, with individuals occasionally reaching ages up to 5,000 years old. Because of its longevity, bristlecone pine contains an important proxy record of climate data in its growth rings. Despite its ecological and scientific importance, bristlecone pine's distribution and associated environmental drivers are poorly understood. Geospatial technologies, including unmanned aircraft systems (UAS), remote sensing, geographic information systems (GIS), and spatial modeling techniques …
Digital Earth: The Impact Of Geographic Technology Through The Ages, Mishka Vance Huq
Digital Earth: The Impact Of Geographic Technology Through The Ages, Mishka Vance Huq
Theses and Dissertations
Geographic technology encompasses a wide range of geographic knowledge, concepts, processes, and artifacts. Because of its interdisciplinarity and integration with other technologies, the paper examines the diffuse impacts of geographic technology within the evolving relationship between technological and societal developments over time.
Isolating Locations Of Potential Episodes Of Cave Collapse And Their Relationship To Cave Level Development Through Major River System Incisions, Ethan William Conley
Isolating Locations Of Potential Episodes Of Cave Collapse And Their Relationship To Cave Level Development Through Major River System Incisions, Ethan William Conley
Theses and Dissertations
Karst landscapes, in which dissolution of bedrock is the dominant geomorphic process, make up 10%-20% of Earth’s land surfaces and supply between 20%-25% of the global population with drinking water. Dissolution dominates the genesis of karst systems, creating flow pathways, conduits, and caves. Cave patterns from dissolution can be influenced by regional factors, such as water table base-level fluctuations correlating to major river system incisions. During periods of negligible regional incisions, multiple cave levels may form. Despite the significant role dissolution plays in karstic genesis, physical erosional processes can enhance the formation of these karst systems and should not be …
