is it possible to mass download basemap tiles..having to go through dozens of times and hit download is a bit mind numbing
Not sure, sorry.
Phenomenal tutorial, helped me understand a lot
Would you be willing to share your R code to do this?
# ANIMATE THE BUILDING # OF A HISTOGRAM (NORMAL DISTRIBUTION) nobs <- 10000 randomnumbers <- rnorm(n=nobs, mean=0, sd=1 ) maxval <- max(randomnumbers) for(observation in 1:nobs) { hist(randomnumbers[1:observation], xlim=c(-4,4), ylim=c(0,nobs/5), main=paste("Observations: ", observation), xlab="Value") }
Formatting in comments introduces line-wrapping in the code, but that is easy to fix once you copy/paste this code to your text editor. Then, copy and paste the code into R and observe the magic.
hello thank you for the tutorial , and I wanted to ask is there an easier way to download multiple data from sentinel 2 as I want to download data of a location through multiple periods of time
Not sure, sorry.
hello, Did you get an error on your account? Ksat 0.099 does not come out
Do you know if you can download heightmap data from this browser?
Sorry, not sure. Best way to find out would be to log in and look at what products are available or email their support people.
Finland was never a Baltic country. Never behind iron curtain. Never a part of Soviet union. Never under communism and never an eastern bloc country.
THANK YOU! We enjoyed it very much, including our son and his fiance, who flew in from California.. Have a Happy one, Jonathan
Thank you so much!
I could not login .. tried several times.. What can I do?
Not sure what I can tell you with the limited information provided. Did you create an account? Did you verify it by the email the sent? If not, I would start there. If you did, ensure that you are using the proper credentials (and make sure that CAPS is off). If you are still having troubles, I suggest that you contact them -- see helpcenter.dataspace.copernicus.eu/hc/en-gb (as I have no control over their authentication process).
@@pattern_lab Thank you for the reply sir, I didn't noticed mail. Now I can search for my data. but downloading is not getting completed. maximum upto 3-4 % and again failing. Is there any solution sir? same problem is happening for some others too..
Could be your internet connection. Images are large. Ensure that your connection can handle it.
Excelente! Tutorial bem objetivo e fácil. Muito obrigada!
Thank you very much for this
thank you so much ,I found a small probleme I've download a sentinel image type 2 (2017) but they're no georeferencing what should I do ?
I don’t have enough information to answer you. Perhaps contact their technical support.
You can download georeferenced data if you try the analytical download and change the format to kmz or tiff. You will have to be logged in to do this.
Thank you very much for this sir. Would appreciate a video on the use of the QGIS plugin. I have been encountering a recurrent error using the plugin- Pixel per meter exceeding the limit.
Perhaps some day…
There is a limitation of 2500x2500 pixel allowed for download with the QGIS plug-in. If you're requesting data at 10m resolution, you might want to split up your area of interest into smaller chunks.
All the images are indicating offline, is there anything I haven't done right?
This portal is shutting down. You'll need to head over to the Copernicus Data Space Ecosystem (dataspace.copernicus.eu/), create a new account and access the data from there. I hope to produce a how-to video for that soon.
New Video: ruclips.net/video/f39LMyPyoqI/видео.html
How did you captured the video? is this a fixed camera?
Fixed camera, yes.
Hi I could not find Sentinel from Data set search to set criteria, Please; help me. Thank you.
You don't provide a lot to go on, but let me try to help you. First, do you have an account and are you logged in? Have you selected a geographic area for your search? If you have, then, if it is a specific Sentinel platform that you wish to search for data from, I suggest using a filter to identify the parameters that you seek. I just went and looked and was able to find Sentinel data without problems.

Hi, do you know if jpg2 files are geo-referenced, and if so could I import them into QGIS? thx
I cannot unequivocally say, because I am not 100% sure, but I do believe that you could georeference a .jpg2 file (the primary difference is that they are compressed with the JPEG2000 standard. However, not all jpg images must be georeferenced. It comes down to knowing your data.
This was really an informative and interactive workshop. It has really given me the basics of R. I couldn’t skip one second of it. 👍
You made this look easy, mine just popped up with "Offline product retrieval has been initiated. Please check again your Cart to know when it will be online." Will it download if I just leave it or have I just sent a request which needs to be checked before I can download the data?
Some data may need to be pulled from storage prior to being able to download it. It shouldn't take very long. I'm not sure if they will email you when it is available or whether it just shows up in your cart. There's a link to information about retrieval from the Long Term Archive at sentinel.esa.int/web/sentinel/faq
How can I do zoom previous to downloading?
You should be able to use your scroll-wheel on your mouse. I use a two-finger swipe up/down on my track-pad.
Why is that??

This story is a grave reminder of what many people had to do to escape totalitarianism.

Simple Trick For Those Asking How to open these jpg2 files..they can use online converter to see their files. (jpg2 to jpg converter online).
Happy Canadian Thanksgiving to you too! Beautiful natural setting 😍
Excelente video…
Sweden wasn't at all protecting all of the Baltic refugees, haven't you heard or read about Baltutlämningen???
How comes Estonian does not know about Finland. Finland is not eastern Europian country. It is a Nordic and western country. The Finnish war heroes who fighted against Soviet union and died would turn around in graves If they heard this. Finland was heroically fighting for it's independence and freedom and retained it. Finland was a part of Sweden over 600 years and autonomious oblast of Russian Empire of tsar 100 years. 1917 Finland announced it's independence and has been independent ever since. So Finland was never under communism and never a part of Soviet union. Soviet tried to conquer Finland, but did not succeed. Nowadays Finland is with other Nordic countries one of The top countries in The world. All of them are prosperous countries with high standard of living. World economic Forum conference in Switzerland Davos ranked Finland the best country 2019 and World happines index report and UN ranked Finland the happiest country 2018, 2019, 2020 and 2021. Eastern Europian countries have never achived that.
Before WW2 Estonia and Latvia were richer than Finland.
@@JohnHenryEden2277 But not now. However I have a feeling Baltic countries are going to do it again. Finland's economy unfortunately is going down.
Finland is a Nordic and a western country. Finland is a capitalist country and was never a part of Soviet union. Also Finland is a member of Nordic council. The Nordic countries are: Finland 🇫🇮 Sweden🇸🇪 Norway🇸🇯 Denmark🇩🇰 and Iceland🇮🇸.
thank you
Sometimes when I select one the data is in .nc instead of jp2, how can I open these? or how can I filter them to only show those who are in jp2?
I am not 100% certain, but the .nc files may be ncdf format, which I believe are for the Sentinel-3 data.
CAN I DOWNLOAD A DEM ?
I am not sure, I have never done so.
Intro to Geoinformatics! My most favourite course I got an A in!
Thank you very much.
What kind of alphabet is important in password?
Authentication on the site is not something that I control, but a quick look at their website clearly states that (scihub.copernicus.eu/dhus/#/self-registration): "Sentinel data access is free and open to all. On completion of the registration form below you will receive an e-mail with a link to validate your e-mail address. Following this you can start to download the data. Username field accepts only lowercase alphanumeric characters plus ".", "-" and "_". Password field accepts only alphanumeric characters plus "!", "@", "#", "$", "%", "^", "&", "*", ")", "(", "+", "=", ".", "_", "-". Password fields minimum length is 8 characters."
Amazing work Tarmo!
Thanks a lot! Hope you're keeping well.
Yay!!!!!! Tarmo, this is cool! Always been one of the cooler profs!
You’re a genius!!
I appreciate your enthusiasm. Thanks.
What software did you use to view those files?
We have a license for PCI Geomatica Banff, but any remote sensing and many GIS environments can open such files. Even R can be used, among other options.
why cant I zoom on specific area, is there some special way of zooming?
Since you do not provide much detail in your question, it's hard to give a precise answer. However, to zoom in and out on the map, scroll your mouse wheel.
It’s just by mouse wheel

Same qestion. How to zoom to a specific are of a product previous to download?
THE BEST tutorial around. Thanks!
This is helpful. thanks for sharing.
Glad it was helpful!
I did basically what Neal did below. I used the cushions from the Phantom to create a platform based on the GoPro base. I did not use a gimbal as I the camera is the snap-shutter and not the rolling-sutter. The platform is oriented nadir (as best we could) and we fly super slow. We also use a zip tie through the dampening springs in the event of a failure. We later did connect a GPS and the system works nicely. Seems that Neal and I had basically an identical setup.
I realize this video is an older post. I myself have constructed such a platform - same drone and camera. I built a vibration dampening layer - like on the standard phantom gimbal set-ups Top and bottom plates cut from 1/16" (1.5mm) carbon-fibre sheet. (ran loose zip-tie through centre of dampening springs in event of failure) - camera was over $5K when I bought it); from the bottom carbon fibre plate, ran 3" aluminum bolts down through mounting holes on ADC snap camera. Rubber teflon tubing used as spacers between the bottom carbon-fibre plate and aluminum camera plate. This permitted access to the control buttons on the top of the ADC Snap, and provided another measure of vibration dampening. Power for camera run direct off positive and negative battery contacts inside the aircraft. Did not connect the GPS - but will in next assembly, onto a Phantom 3 Professional that permits flight planning using DJI Ground Station Pro. Only real issue I have had with this set-up is maintaining Nadir view. For this issue, all my flights were vertical in little to zero wind conditions, else the angular tint of the aircraft in correction locational position, or in flight (tilts down in direction of travel as result of rotor-speed variation). I have been trying to modify a gimbal solution to this problem using a Zenmuse H3-3D, however, this unit is configured for the voltage pattern on a Phantom 2, not a Phantom 3, making such conversion difficult. I will post updates - if anyone is still looking at this thread - early in 2018. If anyone has faced and addressed this issue, please let me know. Happy New Year!

I study soil hydrology, I'm Brazilian and in my laboratory we have this equipment. Your video helped me to use the equipment. But since I'm not native to English, I do not understand some things. For example: why is the calibration 4 cm? Would you have any written content that would help me with these calibration issues? Thank you
