- Pelagos Client DocumentationPelagos Client is a stand-alone web application for visualizing large time series datasets on top of a zoomable world map. A dataset can be provided either as a single static file, a tree of tile files or by a dynamic tile generation server with an optional static cache.
- Mountain Top RemovalContains SkyTruth’s Mountaintop Removal (MTR) Mining related work. We are using Google’s Earth Engine to identify active MTR mines on Landsat Satellite Imagery using a Normalized Differenced Vegetation Index (NDVI) threshold. To eliminate locations with NDVI reflectance values similar to mine sites a mask was created to block roads, rivers and streams, and urban areas from the analysis. This work is the continuation of SkyTruth’s 2007 MTR mining project, which relied upon a time-intensive manual classification of spectral imagery. By using Earth Engine we are able to automate the classification of active MTR sites.
