Remote sensing annual dynamics of rapid permafrost thaw disturbances with LandTrendr

Remote Sensing of Environment, 2022
Abstract Permafrost is warming globally which leads to widespread permafrost thaw. Particularly ice-rich permafrost is vulnerable to rapid thaw and erosion, impacting whole landscapes and ecosystems. Retrogressive thaw slumps (RTS) are abrupt permafrost disturbances that expand by several meters each year and lead to an increased soil organic carbon ...

Interpreting Annual Time Series with LandTrendr

, 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 ...

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

Journal 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.

The Database of European Forest Insect and Disease Disturbances: DEFID2

Global Change Biology, Volume 29, Issue 21, Page 6040-6065, November 2023., 2023
Insect and disease disturbances appear on the rise in European forests and further climate change may make them more widespread and intense still. Despite the need to better monitor and understand insect and disease disturbances, geospatial data on them are scattered.

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

IEEE 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.

Mapping mangrove dynamics and colonization patterns at the Suriname coast using historic satellite data and the LandTrendr algorithm

International Journal of Applied Earth Observation and Geoinformation, 2021
Mangroves play an important role in protecting coasts against wave energy and storms. Mangrove ecosystems provide important habitats for fauna and flora and are an important carbon sink. Loss of mangroves forest may lead to enhanced coastal erosion.

A LandTrendr Algorithm-Based Study of Forest Disturbance from 2000 to 2020 in Jilin Province, China

Polish Journal of Environmental Studies, 2022
Forest resources are of great importance for achieving human sustainable development and carbon neutrality goals. Therefore, this study evaluated forest disturbance in Jilin Province, China, from 2000 to 2020 using the LandTrendr algorithm. The results of the study showed that the overall area of forest disturbance was 448.76 km2 in Jilin Province ...

Mapping mangrove dynamics using LandTrendr on Google Earth Engine

, 2020
The coast of Suriname is very dynamic due to slowly migrating mudbanks in front of the coast originating from the Amazon. Coastal erosion or accreation takes place depending on the location of the mudbanks. The dynamics of the mangrove forest between 2000 and 2018 was studied using the Historic Satellite Archive available in Google Earth Engine.
