Explore the planet more deeply with Esri’s new Landsat Explorer web app! Use the app to both visualize our planet and understand how the Earth has changed over time. Now you can instantly analyze more than 500,000 Landsat 8 and GLS scenes, offering global coverage with over 500 new scenes added every day. The app is free, with no download or installation required.


Landsat Explorer enables you use different spectral bands to go beyond what the eye can see. But the Landsat Explorer app isn’t just about viewing images using different band combinations or enhancements. The analysis tools enable you to perform change detection, create custom masks, make your own indexes, generate spectral and temporal profiles, and more, all on the fly. Use the app to instantly access multispectral and temporal Landsat imagery to reveal how the Earth's surface has changed over the last forty years.


Curious to see how your hometown has expanded since you were a kid? Zoom to your hometown and use the time slider to compare before and after images.  Want to quantify areas of agriculture usage or forest burn? Use the Mask tool to identify specific types of landcover, interactively setting thresholds. Want to measure the extent of a flood, like in Allahabad, India, below? Select two points in time and use the Change Detection tool to highlight the affected areas.

With Landsat Explorer, you can easily and dynamically investigate questions about geology, vegetation, agriculture, and cities anywhere in the world, including the places that matter most to you. And, if you want to share your discoveries, you can save your results to ArcGIS online or as local files. The app is driven by publicly accessible images services hosted on AWS and directly usable in a wide range of applications including ArcGIS Desktop.

Planet’s high-resolution satellite constellations image the entire world every single day. If you rely on imagery from Planet, managing this wealth of available data can be a challenge. That’s why Esri has added tools for managing PlanetScope and RapidEye imagery to its array of free, open-source tools that simplify image management in ArcGIS.

With the Python toolbox for managing Planet imagery, users can create mosaic datasets to manage Planet imagery within the familiar ArcGIS environment. With these scripts, data managers can streamline or automate the creation of scalable mosaic datasets, which can then be shared as image services with internal users or users outside your organization.

Imagery from Planet’s PlanetScope and RapidEye satellite constellations supports numerous applications—including mapping, deep learning, disaster response, precision agriculture, or simple temporal image analytics—which generate rich information products. Once managed with mosaic datasets, it’s straightforward for GIS or image analysts to exploit the temporal aspects of Planet imagery via an image service, to analyze the spectral data to draw actionable conclusions, to use the imagery to provide context within a GIS, and more.

The Python tools work by drawing on the Planet API to query, activate, and download PlanetScope or RapidEye Basic scenes over a given timeframe and area of interest. The imagery is then made accessible to users via the Planet Explorer app or the Planet API.  The Planet toolbox is supported in ArcMap 10.5, and can also be used in ArcGIS Pro.
