Alternatively, you may wish to use asf_search, a Python module for performing searches of the ASF catalog. It also offers baseline functionality and download support. Additionally, numerous constants are provided to ease the search process. It is available through PyPi and Conda. More information can be found here.

asf_search supports downloading data, both from search results as provided by the search functions, and directly on product URLs. An authenticated session is generally required. asf_search uses Requests. Using .netrc credentials is the preferred method for authentication. More information on .netrc authentication can be found here.
If not using .netrc credentials, you may authenticate using an ASFSession object and one of the following authentication methods. ASFSession is a subclass of Session. The session should be passed to whichever download method is being called, can be re-used, and is thread safe.
Advanced Systems Format (.asf)The Advanced Systems Format (ASF) is the preferred Windows Media file format. With Windows Media Player, if the appropriate codecs are installed on your computer, you can play audio content, video content, or both, that is compressed with a wide variety of codecs and that is stored in an .asf file. Additionally, you can stream audio and video content with Windows Media Services, or you can package that content with Windows Media Rights Manager.ASF is an extensible file format that stores synchronized multimedia data. It supports data delivery over a wide variety of networks and protocols. It is also suitable for local playback. ASF supports advanced multimedia capabilities including extensible media types, component download, scalable media types, author-specified stream prioritization, multiple language support, and extensive bibliographic capabilities that include document and content management.Typically, ASF files that contain audio content that is compressed with the Windows Media Audio (WMA) codec use the .wma extension. Similarly, ASF files that contain audio content, video content, or both, that is compressed with Windows Media Audio (WMA) and Windows Media Video (WMV) codecs use the .wmv extension. Finally, content that is compressed with any other codec use the generic .asf extension. For more information about ASF, visit the following Microsoft Web site:
Windows Media Download (WMD) packages combine Windows Media Player skin borders, playlist information, and multimedia content in a single downloadable file that uses a .wmd extension. A .wmd package can include a whole album of music videos that also displays advertising in the form of graphical branding and links to an online music retailer Web site.To download a .wmd package from a Web site, click the link to the package. When the package is downloaded to your computer, Windows Media Player automatically extracts the files that are contained in the package, adds the playlists in the package, adds the content to Media Library, displays the border skin in theNow Playing pane of Windows Media Player (in full mode), and then plays the first item in the playlist. For more information about .wmd files, visit the following Microsoft Web site:
NASA's Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC) is located in the Geophysical Institute at the University of Alaska, Fairbanks. ASF DAAC is supported by NASA to acquire, process, archive, and distribute synthetic aperture radar (SAR) data from polar-orbiting satellite and airborne sensors to advance Earth science research. Most of the datasets at ASF DAAC, including Copernicus Sentinel-1, are open access and freely available to the public for download.
Additionally, asf_search support downloading data, both from search results as provided by the above search functions, and directly on product URLs. An authenticated session is generally required. This is provided by the ASFSession class, and use of one of its three authentication methods:
What is ASF? ASF is the abbreviation of Adavanced Systems Format (formerly known as Advanced Streaming Format or Active Streaming Format), which is Microsoft's proprietary digital audio/video container format, especially meant for streaming media. ASF supports synchronous playing and downloading and any compression/decompression coding, which is quite beneficial to video on demand, live streaming and distance education.
It is rarely known that an ASF file is encoded with MPEG-4 V1/2/3 codec. To play ASF files without any problem with your default ASF player, you need first install the MPEG-4 V1/2/3. You may use the below provided link to find the required ASF codec to download for your ASF player, and then restart your computer to play ASF files smoothly.
Try 5KPlayer once, you will never regret to download this ASF player. It collects adavantages of other media players and it has superiorities among other media players. For instance, it plays ASF files AVI MKV MTS M2TS 4K 5K 8K videos flawlessly, it download online videos music in seconds and it can AirPlay videos music from iPhone/iPad/iPod to Mac/PC/Apple TV.
This tutorial aims to provide a brief introduction to ASF's Search API by demonstrating how to download multiple Sentinel 1 Single Look Complex (SLC) images for the year 2017 for a specific area of interest.
Anyone with an EarthData account can access the data from ASF archive. In order to initialize the download task, you must provide EarthData login credentials for authenticating the session using the auth_with_creds() method. Description of other methods to authenticate are available in the documentation.
In this post, I have demonstrated how to download multiple Sentinel 1 SLC images for a particular area of interest using a python-based script. The goal is to automate this task so that it can be replicated for other areas with ease.
ASF, or named Advanced System Formats, is Microsoft's proprietary digital audio/ digital video container format for Windows media files. An ASF file may contain video and audio, or metadata like MP3 files. This file format supports you to view the file once a certain amount of bytes have been downloaded.
What if you do not want to download a third-party program, or there is little storage space on your computer? Do not worry, you can also choose to use an online ASF to MP4 convert to solve your issue. And this article lists 2 free online converters for you to take into consideration.
Below you will find a selection of sample .asf video files for you to download. On the right there are some details about the file such as its size so you can best decide which one will fit your needs.
I am a newbie to video editing and I've been trying to take some files I downloaded from a stream online (public government videos), to make an Adobe Premiere Pro video out of them. Here's an example link to a file I downloaded that I want to edit:
The link you gave is for a streaming media file, not a download. Most likely, whatever ripper you used to pull down the file did a poor job and produced a faulty file. It may actually play back since most playback applications are rather permissive when it comes to errors in the file, however a professional editing package like Premiere will tend to throw errors if there are major problems in the file since it won't be able to generate suitable output from the file. The best bet is probably to try and find a non-streaming version, particularly since the quality of the streaming version is VERY low.
The GLO-30 Copernicus DEM provides global coverage (with the current exception of an area covering Armenia and Azerbaijan, see Figure 2) at 30-m pixel spacing. When an On Demand job is requested, we download the required DEM tiles from the Copernicus Digital Elevation Model (DEM) GLO-30 Public dataset available in the Registry of Open Data on AWS, managed by Sinergise. We mosaic the tiles and reproject them to the appropriate UTM Zone for the location of the SAR granule to be processed, resampling them as required for processing. A geoid correction is applied before it is used for On Demand processing.
Developed by Microsoft, ASF is an abbreviation of Advanced Streaming Format. This format is used to play the full dynamic images on the Internet to download video while playing the image. You can open it with Windows Media Player.
This is a free and fast online converter, which converts PDF, image, video, document, audio, e-book, and compressed file formats to other formats. It is straightforward to use. You only need to select the format on the drop-down bar (such as the document in the document converter). Press Go to reach the upload file page, and you will be prompted to download it.
