Easiest way to download High resolution Satellite imagery (15 cm) using QGIS

hello everyone welcome back to another brand new video of this channel uh in this video I'm going to show you how you can download high resolution Saturday imagery using qgis for our day-to-day users uh as a geography information analyst or as a emergency analyst we often use very high resolution set at image that is but often it is fine often it is very difficult to find authentic sources from where we can download uh satellite imageries with high resolution for our particular study area so in this video I am going to show you some simple steps by which you can download very high resolution imagery using qgis for this particular purpose you will need a plugin called type plus this plugin isn't usually available within a qgis own plug-in directory you need to download it from a particular link I will provide the link in the description box of this video so let's get into this video uh and we will I will show you the step-by-step process to how you can download a high resolution image that is using tile plus so once you are into the qgis interface you need to go to the plugin option from here from menu bar and then you will see the management plugin sorry manage and initial plugins options then you can have to click on here and now you will have to get into install from zip file so once you are here you will see a new box here you have to show the path where the plugin zip file is located uh click onto this three dot icon then you have to go to the directory where the zip file is located of the of the plugin that I I have mentioned so my uh plug-in C file is located in desktop for finding it easily I've already saved it in desktop so that I can show very easily in this video so this is the file of the plugin so one click on this and open so and now you have to click on this install plugin option so you can see that the plugin has been installed successfully now close close the uh close this toolbox then you'll see there is an icon uh this is the tile plus uh plugin which has been which I have one which has been installed uh just now and now click on here now you'll see there is a new interface will be coming on and from here you have to select a map you can select any map as where you you desire uh like you can you can download any any Maps like Google Map Google terrain Maps or history it's satellite or history light gray Maps whatever you want for my particular case I will be downloading Google satellite so click on Google satellite and click on this plus icon and here it is the best map of Google satellite so now you have to select if any particular study area for your case so for my study for my case I might be choosing any study area within the UK so uh let's get them to Heathrow Airport so this would be easier because uh which will be downloading for our case so once you are here you have to set your study area within the interface uh sorry within the canvas extend and then you have to click on this Google option and from here you have to click on export and then save this so it is the save raster layer as uh Tool uh it is the usual tool which we how we uh save our raster files or any Vector file or any any kind of layer is in qgis so from here you have to first uncheck this option which is called create PRT it will easily save any trust open as virtual dial as well so you don't need that so uncheck it fast then you have to select your file format so for my case I might be uh I will be uh exported as a geot file so if you can download it or you can sorry you can save it as any file format it can be JPC it can be um that's the PNG or any other value can be also uh it does image in file own file format dot dot aimg so for my case I'll be downloading our sorry saving it as got file and then you have to set the file of uh name or in a particular folder where you will be saving the uh the file so maybe I'll be saving here in downloads uh and then London folder so it will call it I will call it as uh Heathrow foreign system so for the Britain or UK the default coordinate system is uh British national grid so if you can see click it and then there will be a new error will be coming it you don't need to uh like care about it you just you can just ignore it and then you have to set the map canvas extent so once you click on here you will see uh all the columns uh you'll set to zero and rows will also be zero so it is not a particular thing so you have to set it as far as or your own you have to set your a resolution raster resolution once you set your rest resolution the column Center also will be automatically set so for my case I will set the horizontal and also vertical resolution has 0.1 that is 10 centimeter you can set up to anything you want but keep in mind that in and for Google satellite the highest resolution that is available is only 15 centimeter you can get up to 50 centimeter or anything more than that not anything less than that and then a Groupon one again so once you have uh yeah you have uh set every uh every parameter now you can just click on uh okay then once you click on it you still see that the file is uh is is will start uh processing as uh whether the pride will be start exporting so it will takes uh for uh it takes some time uh there may be a five or six minutes depending on the speed of your profit processor for some processor it might take around one minute or two minutes but in most cases if you are using laptop or any normal desktop it will uh take around uh five or six minutes so I will uh continue back again once the file is downloaded so once the image is exported it will automatically be installed on the map uh now necessarily you'd also see a window after which which asks you to uh setting the transformation coordinate system so you don't need to do anything here just click on OK and now yeah we can check the quality of the exported image if you want so zoom in whatever you want and see that how much better quality diameter is so if you want to check the uh the reservation in the properties you just right click on here and go to the properties uh scroll down and you see the pixel site is 0.1 that means 10 centimeter which is set earlier uh if you want to compare with with the base map uh uncheck both the base metals and the raster objectively passed okay it's actually the same as the base map so in this way you can export you can download any high resolution image in your particular Studio yeah and most interesting fact is that this imager is automatic edit your referenced so you don't need to uh do anything like you don't need to uh geo-reference it manually after you after the what is completed so if you uh if this video is helpful for you or if you find this video useful uh please don't forget to like the video and subscribe to my channel and stay tuned for the next video goodbye foreign
