We have never had this good of a perspective of our changing planet because of satellite imagery. Some of the biggest challenges we face today are best understood through satellite land cover. This is because remote sensing covers that much more ground. Their main goal is to support scientific research using geodesy technology. For example, think of flooding, plate tectonics, and earthquakes.
Instead of spending days searching for a good base map, you can tap into this list of free satellite imagery data. It looks like Landsat 9 is set to launch in September It will have similar specifications to Landsat 8. Its visible red, green, and blue bands will have a meter resolution, plus one panchromatic band at 15 meters.
Is there any news about Landsat 9? What are its specs and when can we start seeing some of its data? Just in , the US government softened restrictions for sharper imagery available to the public. Now, the general public can obtain 50cm 0.
Unfortunately, they are not open to download in most cases. Landsat-1 was launch in summer and this was the first of its kind for Earth observation satellites. So, is as far back as you can go for remote sensing satellite imagery.
Has Big Brother put a kibosh on that type of access? Hi, unfortunately none of these satellites will be able to help you. The best resolution available commercially is Worldview-3 at 0. If you bring out a tape measure to the ground, you can see how large that pixel is. Do you have any recommendations? This is a very impressive list. What would be the best source to detect FIRE globally as fast as possible? Imagery was sharp and loaded quickly. Unfortunately Arc2Earth went out of business and no one seems to have replaced them.
I think there was licensing problems with Google. Where can I access imagery as good as Google for a decent cost? Clear editor. Upload or insert images from URL.

To search for a location, you just need to enter it in the field. There is no possibility to download but the tool allows sharing free data to social media like Facebook, Whatsapp, Telegram, Twitter, or via email. There are no specific features for analysis apart from sorting out map labels, live and daily satellites, daily fire spots, or storm tracks.
There is an option to measure area and distance and zoom to center as well as to pass to your location. The product is designated to help rescue missions to manage disasters and respond to emergencies. It provides information on nature calamities like hurricanes, typhoons, wildfires, floods, explosions, earthquakes with brief descriptions and photos. You can search for disaster events by their name and date from most recent back to Earlier images are available in the archive.
You can save images to your computer with a preview as TIFF files. The up-to-date images provide information on disaster management fires, floods and air quality. Browsing is available from a PC, tablet, or smartphone. Search is possible by events and dates either clicking or swiping the timescale.
Most of the photos are available in standard geospatial projection, Arctic and Antarctic. Users can share a permanent link or download the required free satellite images via the snapshot option selecting the preferred resolution 30 m km , file format JPEG, KMZ, GeoTiff, PNG , zipping, and clicking the download button.
The free portal provides a plethora of overlays, base layers, and additional layers for multiple modifications, to check air quality, dust storms, droughts, floods, vegetation, ash plumes, shipping, among others. Detailed online tutorials to use and download free satellite imagery help site visitors navigate the tool highlighting its multiple features. The mission lasted from to You can zoom in and out or move the map with a mouse. The product has several release versions.
The latest one is 3. The free satellite imagery of the source can be loaded via the link to the dataset, registration is required. VITO provides free satellite imagery on its product distribution portal available with and without subscription. The subscription offers advanced search features as well as the possibility to get the required data in the future once they are available.
The imagery on the portal is grouped into several collections e. Resolution ranges from m to 1 km. In each category and subcategory, the users define their search criteria like the region of interest by dragging or typing the country or continent in the search field, specifying the date range, and clicking the search button.
The portal has a demo tutorial explaining how to use it. Viewing free satellite imagery is allowed anonymously while downloading requires registration and accepting the terms and conditions. The files can be retrieved in the KML format.
The search results come with a thumbnail and can be downloaded one by one or all together. For large data amounts, it is best to place an order and get an email link. For quick download, install an FTP client. Some free collections e. File stitching and band combinations are performed upon request in customized order deliveries for specific users. The portal is a large repository for free satellite image data housed and operated by the Department of Geographical Sciences at the University of Maryland, U.
The source is useful to anyone interested in global environmental systems. The free satellite imagery on the platform shows the land cover and its changes on the local and global scale. It embraces forests, crops, grasses, sands, urban constructions. The data applications include science, environment studies, resources and disaster management, computer science. It provides open-access geosciences data. Each data category has a video tutorial with user guidelines. Please answer my enquiry above.
I can do this with IR scans. What is the best resolution of these scans you can provide. Can you accommodate me? Scroll down to band designations. For example, you may be interested in the thermal infrared and SWIR bands. But you may want to look at some of the other research articles that have been published.
If I want to do research about air pollution or air quality, what data set should I mark? And after I get them how do I proceed? I zoom out and I can see that this area in red has been highlighted and is will filter out my selection to this area. When I try to plot it, I just see a random array of colored panels. How do I either transform this shapefile into the correct satellite image, or download the geoTIFF files?
For reference, the object I downloaded contains the following elements for each of square panels:. Like many others, this is all Greek to me. However, the reason I am looking into this at all, is that we need the satellite data and a means to interpret it in order to update our old floodplain maps. It does not need to be official or certified, just reasonably accurate. How difficult would this be to accomplish, and how big of an area can we cover?
I wanted Sentinel satellite images because of resolution but cannot get for that period since they only cover from I have decided to use Landsat but when I download cannot get georeferenced ones and aslo they are full of cloud cover. Kindly assist. Are location coordinates i. GPS data in Earth Explorer subject to copyright restrictions? I am creating an adventure game that will make use of such coordinates,and I would like to know if it would be okay to do this. Note: No maps or images will be used.
Can you be more specific for which imagery that you want a service for? Is there copyright limits on the imagery as with anything that has to do with Google…. Hi Jim, thanks for the comment. Let us know specifically where you are having issues… As with everyone, we are happy to help out wherever we can. Wow, no instructions on how to download imagery, just vague waffle.
You need to give clear and concise instructions. Also number of Indices, suitable for geology, vegetation studies etc.
