 on the behalf of Shashikant Sharma, myself RJ Banderi is presenting from Sakthi sir. Okay, please go ahead. So, there are 10 problems. So, I will go one by one and what exactly we have to do for that problem and what will be the requirement and what we will be expecting from the students or participants. Okay, let us take first one, mapping of natural resources or a manmade features. So, basically, we have to map the natural resources like agriculture area or forest area, water bodies or manmade features like built-up area, so any manmade constructions. So, that kind of resources can be mapped. So, to map these features, what will be the requirement? We need remote sensing data like list 4 data or list 3 data. So, this type of data will be required and one has to learn how to interpret the imagery. So, we have to interpret the imagery and we have to extract the information from the imagery. So, we have to work out what type of tone or texture or color will be the reflecting means resembling the particular features. So, identification of the features on the imagery. So, it requires the skill to interpret the imagery as well as some ground knowledge also is required. And after knowing all these things, we have to do the automatic extraction of the features. So, for that computer-based image processing also is required. And all this type of input data will be available on the bo1. So, one can take this type of problem and work out the flowchart for it and one by one step can be executed. And finally, come out as a map, thematic map. Thematic means it represents particular subjects. So, come out with some particular subject to map or a thematic map. So, that will be the output. And if you see second problem, so that is change detection based on Awebs or List3 data sets. So, what type of change detection? Any, suppose a forest area, what was the before? Then this date. So, two type of database we have to take and interpret both the data sets, whether visually or digitally. And then overlay to both the data set and come out with the change. So, one has to work out all the steps and flowcharts and execute it one by one and come out with the change map. Change map as well as change statistics. Okay. Then third one is LULC, land use land cover change with hotspots using land use land cover maps available from the bo1. So, we have on the bo1 to 50,000 scale as well as 50,000 scale data sets. One can directly download this readymade data set, use it and come out with change. Particular change wherever hotspots means dynamic changing area. Means some significant change should be observed. So, that change map one has to prepare as a output and come out with the statistic how much change is there. Then fourth problem, flood mapping. So, we observed that in India at many places flooding is happening in every monsoon season like in Bihar, Kosi river, Bramputra. So, at many places we observe the flood. So, we have to map the flood for that we have to consider pre and post season data sets. So, post pre monsoon just you observe that what will be the normal condition and then post monsoon how much area is inundated. So, that area will maps we have to prepare means one has to prepare and come out with the statistic how much area is gone under the inundation. Then state wise healthcare indicators maps. So, this type of database one has to take from the health department or that sites and then healthcare map indicators even can find out and prepare the healthcare maps. So, there is not much remote sensing data sets roles. Then sixth one is locust infestations, stubble burning, low lying area mapping, zoom cultivation. So, we observed that at many places there is a locust attacks and in particularly in Punjab you can find out stubble burning means residue crop residue to burn it for next cropping to clear this residue for next cropping season. So, to find out this type of area one has to take that seasonal images and interpret that those area particularly and find out how much area is under stubble burning. Then low lying area particularly where in monsoon season it goes under flooding means water gets accumulated in the low lying area. So, for this type of study you can use the DEM and find out slope so that you can find out low lying area. And in case of zoom cultivation particularly this type of phenomena observed in the northeast area in hilly area particularly. So, in the northeast area what happens every year or for a particular season people used to burn the forest area and clear some patches for that agriculture practices. So, this type of practices is happening in northeast area. So, for that you have to study the images wherever this forest patches are gone means vanishing and those area one has to map and over period of time they take one or two crop or a one or two year they do the practices and then they left over those area for natural regeneration. So, this type of phenomena we have to interpret from the imageries and bring out with the map and how much this zoom cultivation area is gone under the agriculture area under the cultivation. Then in case of transportation networks linear networks mapping. So, for this higher resolution imagery is required particularly Cartoset kind of the imageries. So, that imageries can be used and linear features can be abstracted either visually or digitally and drainage map in case of drainage map it is of course it is of some at some level it is observed on the image. But DEM is the pattern you can directly derive these images from the DEM Cartoset DEM then land degradation maps. So, this is actually a map of a digitification area or a land which is undergoing under degradation. So, some processes one has to interpret on the imageries and bring out the land degradation map whether it is degraded or under good condition like one example water erosion then wind erosion vegetation degradation. See you can observe okay previously it was a good area good green area and then now some vegetation is going under degradation. So, this kind of land degradation maps can be prepared and come out with the final outputs of the map and area statistic. Then health infrastructure population age group etc for vaccination. So, this kind of data can be available from this NIC national informatics center means tabular information what much role of remorse sensing. And then 10th one is detection of change in water bodies reservoir and wetlands. So, for this two time frame databases required and you can map a generate map of two time frame database integrate it and come out with the changes whether water bodies shrinking or it is expanding or whether reservoir number of reservoirs are increased or a wetland area is increased. So, this kind of studies can be done and come out with the wetland changes map or water body changes map. So, this final map can be done and 11th is a means can be taken your own topic. So, these are about the topics of the map at home. Okay, that is all from the oversight. Are there any questions we can take some if there is any questions from the YouTube. Yes, one question was is to be allowing all this data even after the completion of this event like map at home will that data be available for them to use. Yeah, in general, on that one website, a lot of data is available free of cost every time. But here, in some special cases, we will be taking permission. So, suppose if you require some high resolution data or anything, we will try to take permission, but it will be available only for map at home participants only, because all, I mean, general rules, whatever things are available that we cannot make it for, I mean, indefinite. Okay, so thank you. Shivana, just add that in the comment. Okay, like, okay, yeah, we'll hold on till then. And then one question which came is how to download the data. I think Shivana, you should reply to that saying there will be a live demo for one problem statement. I think that is just tell them that on the webinar, I think it is the third event demonstration of an example by Mr. Nellay Mishant. Okay, just tell them that we will show you how to download it one, and you can use that to use information to download other data using ISRO resources, like the resources we have. Yes, okay. Each for each platform that given us videos, right, MOSDAQ, Vedas, et cetera, and how to download above and Vedas, MOSDAQ, there is YouTube links. So just as them to go to that, we won't be making, tell them clearly, we won't be making just videos for this event. Yes, sir. There will be a separate session by Arul for downloading the data, how to download data from Bhuvan, because largest number of data is available on Bhuvan. So that people have to understand very thoroughly. Okay, sir. Because there was a question about list 3 or 4, I think, and demonstration, et cetera. So yeah, after Mr. Arul's presentation, just tell them that there will be a live demo using QGIS, how to download this data and do a one problem statement. I think that will help them a lot. Okay, sir. I could be added as a comment. Shivannan, just add that as a comment. That same question comes also. Okay, sir.
