Hi,
Welcome to Dawn of Geospatial World. Where you can learn about GIS, Remote sensing, Satellite Imageries.

About this Video
In this stepbystep tutorial, we'll show you how to download ASTER DEM data for free. ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) is a satellitebased mission that provides highquality elevation data, making it a valuable resource for a wide range of applications, including geographic information systems (GIS), geological analysis, and topographic mapping.

Here are some specifications of the ASTER satellite:

Launch date: December 18, 1999
Orbit altitude: 705 km
Orbit inclination: 98.2 degrees
Spatial resolution: 1590 meters for visible and nearinfrared (VNIR) bands, and 90 meters for thermal infrared (TIR) bands
Spectral bands: 14 bands ranging from visible to thermal infrared (VNIR: 3 bands, SWIR: 6 bands, TIR: 5 bands)
Swath width: 60 km
Revisit time: 16 days (for global coverage)
Mission life: 5 years (extended to more than 20 years with ongoing operations)
Instrument: Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER)
Agency: NASA and Japan's Ministry of Economy, Trade, and Industry (METI)

During this tutorial, we'll cover everything you need to know to download ASTER DEM data for free, including the software you'll need to access the data and where to find the download links. We'll walk you through the entire process, from navigating the NASA EarthData website to selecting the right data for your project and downloading it to your computer.

Whether you're a GIS professional, geologist, or student looking to explore elevation data, this tutorial will help you get started with ASTER DEM data without spending a dime.
