Just to add when RGB is 4-3-2 it's natural colour or True composite. Anything other than that like 5-4-3 (colour infrared) would be False Colour Composite (FCC). Very nice tutorial. Really helpful. Thanks
Dear Sir, I recently came across your insightful TH-cam tutorial on Landsat 8 Image Classification using QGIS, and I truly appreciate the clear and informative content you provided. Your step-by-step guidance was immensely helpful. I would love to see similar tutorials for Landsat 8 Image Classification using ArcGIS and RStudio. If you've already covered these topics, could you please share the links in the comments section? Your expertise is invaluable, and your tutorials make complex processes accessible to learners like me. Thanks again for your dedication to sharing knowledge!
This is such a wonderful presentation, absolutely wonderful job. Your patience and articulation makes this work much easier. Thank you, you have earned yourself a subscriber.
I feel at 8.37 minutes wavelength setting is not correct...as it is for 2,3,4,5,6,7 not for 1... Please see in your video center wavelength shows 7.0; that is not correct. But I must appreciate that it is excellent guide
I'd like to thank you so much for the nice tutorial you've come up with on SCP. For me, it's just the beginning of a long journey, but now I feel encouraged to move forward. Keep posting more you're an excellent coach!
Thank you so much brother for such a great tutorial! Please make some tutorials on Landsat 8 unsupervised image classification, cloud masking, accuracy assessment, and LULC change prediction with CA-Markov Model.
HI, Everything was going good. I was following all of the steps but during 26:28 the option you go for i.e classification. I am not getting this option displayed there in its place. I have only option of Home, Training inputs and ROI. Do you have any idea to make it show up? Thanks
I’ve downloaded the zip file and I found xml format (not mtl) I’ve tried to convert it to .txt but it doesn’t work . Could please explain how can I risolve this problem? Thank you so much
Thank you so much for these wonderful tutorials. Please can you do a new tutorial for the updated earthexplorer website? it's difficult to get this image as you did with the updated website. thank you
Thank you for your video. When it comes to RT_clip bands I can't get file for the first band (B1). Only next six bands. What can be the reason of such difference with the result of SCP in your case?
@@ARIJITGEOLOGY I figured it out. There should be some option to active them while loading the Reflectance Bands from Clipped ones. As I was working using Sentinel - 2A satellite imagery, I was able to activate it. I couldn't able to find while working with LANDSAT imagery tho. at 09:37 that guy has an option only to blue and green bands option. May be we should check that option to get remaining bands.
Thank you very much for this. Please, I tried the tutorial but whenever I do the reflectance from the clip files, band 1 is always omitted! I have tried all I know, including upgrading Qgis to the latest version still no success. Please I will need your help here. From one of your devouted students!
According to the "Frequently asked questions" of the plugin, there are some bands that the plugin avoids in the pre-processing for a semi-automatic classification. "Which image bands should I use for a semi-automatic classification? In general, it is preferable to avoid thermal infrared bands. If you are using Landsat 4, 5 or 7 you should select bands: 1, 2, 3, 4, 5, 7 avoiding band 6 that is thermal infrared; for Landsat 8 you should select bands: 2, 3, 4, 5, 6, 7. Landsat 8 band 1 is generally avoided because it is very similar to the blue band and it is mainly used for coastal aerosol study. Landsat thermal infrared band is excluded from classifications because values are mainly related to object temperature." Maybe he is using another version of the plugin and thats the reason why he still have the Band 1. Anyways, I think that we can use the original Band 1 in the furthing processus.
Hi mate, i have a question, i don't have the classification option below the training input, do you know why it could be? i have Qgis 3.16, cause of this problem i can't go on with the process :c
I like this tutorial, but what if my study area, for example, is composed of two images NE and SW, how can we combine the both images (NE-SW) to analyze them with the Scp method?
Lovely and very informative video. Thanks. Kindly make the next video on converting it in to vector and calculating amount of the given classes please. Kindly also make a video over authenticity check of the whole classification in case we need to do it for scientific publication please
First of all thank you this helpful tutorial..My data set is belong to Landsat 8 and also Level-2 and Collection-2. So what should i do those data set? Which stage should I start from? thank you so much :)
Thank you very much for this very rich video. Please, could you produce another wich shows how to cut the part of NDVI for exemple according to the limits of the zone of study.
When I acess the landsat Natural Color Image, only RGB bands show up. Which particular image do I need to download to have the multiple bands like yours?
This is very useful. I am a complete novice in this area, please could you explain to me how to acquire the data over an entire country. The USGS website limits the images to very small areas or am I doing it wrongly?
Hey🙌🏻 i think i have the same problem as you at 8:56. I can‘t choose the folder „clip“ for „directory containing landsat bands“. No meta data or bands are found. Do you habe any solution? Cause you skipped the problem and everything worked.
Thanks for the video. I'm following along and tried to clip the Landsat images to a shapefile of a watershed that I already had created. This resulted in QGIS hanging up and not responding, so had to force quit. I'm not sure if this is a glitch with QGIS (the latest version seems to have a few bugs) or perhaps this task is too resource-intensive. If you have any suggestions, I'd appreciate them. Thanks
Thanks alot very helpful video. Please tell one thing ,my area of interest covering under 5 images of Landsat8 so do i need to first merge same number band of different area or it can be done directly in SCP plugin.
Is it possible to create a ground hillshade type model (to see ground features) with just DEM and Landsat 8 (for when NO LiDAR is available)? For example, do math on a DEM based on a classification mask? I know that LiDAR will have less holes because a laser gets to the ground more than a Landsat band would, but that is ok if it averages out the parts that did get through. It just won't be as accurate? Thanks
Hello sir, thanks for your handy tutorial. I have one problem, I hope you I explained all the things to make you understand. My problem is: I have classified NDBI into a Built-up area and non Built-up area. Over my study area there is a multiple municipality. So how can I change the raster value ie Built-up area raster value by population and each municipality has different population. Is there any way to solve this problem. One way is by clip the raster by features and reclassify. But I want whole study area.
You are amazing. Thank you very much. I was needing an introduction to Satellite Imaging, and this is fantastic ! Do you know where is the standard place to start with in depth theory ? Any Book, open resource, paid, website ? Should I start going to NASA ? I would like to get really good in producing/processing satellite imaginery on a regular basis, for my future projects, and it would help !
At 9:36 you've checked "only green and blue bands option" but this option isn't showing in my interface. Only "add bands in a new bandset" option is available. What should I do?
Plz.... Could you make same tutorial again in updated version of SCP? I think most people having issues with recent scp plugin. It'll be helpful if you do it. I'm waiting for your response Thanks 🙏
When I try to save training sample (ROI which I create for a class), it gives error. It proceeds up 73% and then produce error showing MTL file is not valid layer and cannot read. Any help will be highly appreciated
How does it work for Landsat 5 for instance that band 6 is the thermal band? I should not add it to the lot of bands that will be analyzed, is that correct? what will change in the process, can you say?
Hi, I was wondering if you would be able to make a similar but looking at mapping change over time? I am currently working on my undergraduate dissertation looking at vegetation change in north east Iceland from 1970-2020 at 5 year intervals using Landsat data. Any help would be greatly appreciated! Thanks in advance :)
Hi, I have a file with temperatures and coordinates from weather stations at 10 minutes interval time over the next 4 hours, the temperature in centigrade. I need to make a layer from every time interval from set weather stations. If I want to show in every layer the temperature using areas with a different color inside the map for every weather station to identify color with its temperature. Then to filter by layer and also select one or more combinations to get a map to analyze change temperature for 2 or 3 hours. The raster interpolation is it necessary in this case? Any advice is appreciated. Thanks in advance for your help!
can you please tell how we can compare two maps (current species distribution vs future specices distribution map) to shows change in habitat suitability?
I have installed the semi-automatic classification plugin on QGIS 3.20.0(Odense) and also downloaded Landsat 8 images and wanted to test one of the semi-automatic classification procedures. However, I failed to create a training input file (*.scp) getting the following information on my QGIS main window: Information [4]: Select a raster; raster is not loaded.
