When using imagery or remote sensing data in your field of study! one of the first steps you ne! to take is to visually examine the data to discover the desir! features within the remote sensing data. Esri offers content and applications for you to examine and analyze various images. In this blog post! we will discuss in detail the Landsat Explorer application that Esri offers for your use.
Application highlights some of the capabilities for accessing
Landsat imagery layers power! by ArcGIS for Server and Landsat Public Datasets running on the Amazon Web Services Cloud. The layers are updat! daily with new Landsat imagery. Creat! to help you visualize our planet and understand how the Earth has chang! over time! Esri Landsat Explorer harnesses the power of Landsat satellites that collect data that is beyond a lead genaration we’re us to tracking email open and click rat the nak! eye. You can leverage different Landsat clusters to better explore the world’s geology! vegetation! agricultural lands! and cities. Additionally! you can access the entire Landsat archive to visualize how the Earth’s surface has chang! over the past four decades.
After a brief information about the images! we will look at where we can access Landsat images and move on to the details of researching and analyzing changes in the image.
The nature of each image dataset is relat! to
the type of sensor us! to how to write a blog that ranks higher in search engines collect the images. Technical details of each sensor type can be found in the metadata for each dataset. Additional information about the images may include items such as the visible area! text services collection date! or other technical aspects of the sensor. Understanding these technical aspects of the image will improve your ability to find desir! features in your field of study. Remote sensing data collects information about features and presents this information as values in an image stor! as raster bands . The
measurement of a single feature is record! as an element in one of these raster bands. Individual image datasets may contain many raster bands. You can combine and display these raster bands as band combinations or band composites. These band combinations are us! to display image data on a map! depending on the visualization ne!s and characteristics.
To learn more about how raster bands can be us! to discover a desir! feature! you use the Landsat imagery layer in the ArcGIS Living Atlas of the World. This imagery layer is bas! on imagery from the Landsat program! which uses satellites to collect various raster bands us! to monitor the Earth.
