The Earth Observing System's LandViewer application is an online GIS-assistant which provides a set of advanced tools to perform real-time remote sensing data analytics. The site allows you to access and use a constantly updated satellite imagery catalog.
One of the coolest features of LandViewer is the ability to create your own time-lapse animations using satellite imagery captured over time. With this function you can easily create videos or animated GIF's which show changes to locations over time. For example, in the image above you can see the construction of the Bhadla Solar Park in India between 2016 and 2019 using Sentinel-2 satellite imagery. The time-lapse tools in LandViewer allow you to customize the quantity of frames per second, resize the video, create a GIF, show dates and download the results.
The imagery in LandViewer provides access to imagery from the world’s top providers of high-resolution satellite imagery, including Airbus Defense & Space, SI Imaging Services, and SpaceWill. It also allows you to browse, preview and purchase products from Pléiades 1a/1b, SPOT 5, SPOT 6 and SPOT 7, as well as KOMPSAT-2, 3, 3A and SuperView, Gaofen 1, 2, and Ziyuan-3.
LandViewer includes tools which allow you to perform time series analysis of satellite imagery. For example you can perform analysis of vegetation growth, crop identification, and land use change. Landviewer is therefore an important tool in a number of different fields. In agriculture monitoring it can be used to identify high/low crop yield and identify different types of vegetation areas for fertilizing, sowing/resting, and watering. In coastal monitoring LandViewer can be used to analyze coastal zones and to analyze water temperature, salinity, phytoplankton, and potential threats to shores. In forestry LandViewer can be used to identify identification of specific zones by vegetation density, vegetation type and monitor deforestation.
