Interpreting Annual Time Series with LandTrendr

open access: yes, 2023
AbstractTime-series analysis of change can be achieved by fitting the entire spectral trajectory using simple statistical models. These allow us to both simplify the time series and to extract useful information about the changes occurring. In this chapter, you will get an introduction to the use of LandTrendr, one of these time-series approaches used ...

Long-term vegetation changes in elephant-related areas of concern in Kruger National Park, South Africa. [PDF]

open access: yesEcol Appl
Abstract African elephants, whether alone or in combination with other environmental factors such as floods, droughts, fire, and other herbivores, have significant impacts on large savanna trees, often contributing to declines over time. However, their effects on woody vegetation in general remain less well understood.

Dynamic monitoring of urban built-up object expansion trajectories in Karachi, Pakistan with time series images and the LandTrendr algorithm. [PDF]

open access: yesSci Rep, 2021
AbstractIn the complex process of urbanization, retrieving its dynamic expansion trajectories with an efficient method is challenging, especially for urban regions that are not clearly distinguished from the surroundings in arid regions. In this study, we propose a framework for extracting spatiotemporal change information on urban disturbances. First,

Urban Renewal Mapping: A Case Study in Beijing from 2000 to 2020

open access: yesJournal of Remote Sensing, 2023
Understanding the distribution and land history of old urban areas (OUAs) and renewed urban areas (RUAs) has become the key point of urban management. However, it is hard to acquire adequate information for lack of pertinent detection methods.

Mapping Annual Global Forest Gain From 1983 to 2021 With Landsat Imagery

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
The world's forests are experiencing rapid changes due to land use and climate change. However, a detailed map of global forest gain at fine spatial and temporal resolutions is still missing.
