 we have data analysis as a second unit once you complete your database creation of editing Then you do that as a ready now. You have to do the analysis right once you have extract map Pantodeo non-spatial data Then errors being removed now you have to analyze like I I want to know how many water bodies I have And what is the total area of the road? What is the total length of the road? What is the total perennial water bodies?oon మా ఎయ౗త్త్తరా చానౕత్నస్లింందిదింప్త్టాలూతులెఘ్స్కిమ్రందిక్నకాన్తునాన్రురుచామ్కోనులెబర్మూదావానక్తాన్త్ప్త్తోస్ప్� అనా నింమతాల ఱిని నిస్వాకై వాలెరంన్ మిల్సల్ మిల్సటిని ప౰రంరడోవర నిమావతినాటాకూలస్ మాల్సల్ హాల్రంనా సపనియాదాంని మార్సల్ � ఏ్వ్ట్ ఇసునినిసి ప్రుద్ ప్దెస్య్ చనిక్యందులారారిక్టు ట్ల్యురినులుత్లుయుత్నువత్ పర్ఠర ప్రందర్రలిక్త్కరారిసి కరర్నుమె only 3 entities can measure the point length of the soil. we have the overlau operations one upon another for example we have the soil we have the agriculture land in GIS you can create different team wise layer wise all agriculture lands have a layer we have made soil land and water bodies have been made if you overlau one upon another you will be knowing if you deliver your water source map you will be understanding that it is a irrigated area because you have plenty of water bodies so the production of the crop is very high whereas other parts we do not have the water body then that area production is very less or you may say more fellow lands you can compare directly when you do the overlay analysis the weeds will help is find out why it is maybe less production గాచిందాం విసి సిపారండి మనోష్టెవిక్టాచరం వమరిందావా రాస్నాటింద రంచారంత్టికాదందాఠిరంగతారందిన థమిసిక్ధంవ్టాన పమాదాటికాం less than 500 metres from the settlement area. So when I make it the proximity analysis in GIS it will create a 500 metre buffer from that location where you are planning the school so how many villages I can cover in my gram pancha if I propose this location. the only one we'll place for example. Then make a ring from the point where you have the asserting facility. If it is PAG otherwise the same school if I propose here ఎతార్ర్ క్ంవ్య్ ఠ్ంమ్ర్, న్ంత్య్స్ న్జ్న్ ప్ంద్ ఆవ్ఘుప్ధాచ్యన, ప్తోజామైమ్గాన్ ప్న్సచింలాల్యన్ మ్కిత్ట్చతార్. వ్పిక్ మ్

measurement of length, measurement of area any special feature which you see jays quickly you can measure here there are measurement tool or when you extract in a table or from automatically the length or area will be stored right so if you if you wish to see there is a measurement tool jays from here to here what is the length of the road quickly you can analyze any feature not only road it may be water body it may be agricultural land it may be particular point of the building that also you can measure using these tools all geospatial measurements are can be done using these three types of geospatial measures point line polygon three can be seen then we have neighborhood operations as I said buffer which is very very important neighborhood analysis tool this buffer tool is very very important buffer tool can be done for point line polygon all three entities you can run the buffer buffer will give you like the ring no which has shown given 100 meter 200 meter 300 meter 1 kilometer 10 kilometer 20 kilometer doesn't matter for example I am putting one facility here for example this is a community radio station I want to establish in the KK Hende Kopen University if I start here I need to prepare a proposal that from this point community radio station within 10 kilometer radius how many villages or how many houses I am covering that I can give with the help of GIS if I put the query in GIS buffer query it will make a ring of 10 kilometers from this point making center of this facility from the KK Hende Kopen University it will make a 10 kilometer radius so how many again how many villages are covering from megalaya state how many are from a sub right total how much population will get benefit out of this community radio station if I establish in KK Hende Kopen University that quickly you can analyze without going to the field with the help of this buffer tool right similar way if you put a irrigation canal how much land will get the benefit it's an irrigated area but if you put a new canal irrigation canal how much land will get the benefit maybe with the 1 kilometer radius that quickly it will demarcate it so under that again 1 kilometer how much land again fallow which is not cultivable which we can bring under cultivation that we can analyze we can see physically if you do the special analysis of the buffer point buffer line buffer like dryness and polygon buffer polygon buffer like you have the water body you want to make a some trench or compound wall there is a forest area you make a compound wall or you want to say the state boundary is that I want to make a boundary wall in this case also you can use one meter two meter three meter ten meter any meter buffer if you wish you can use all three and it is using this particular buffer option in JS environment which is very very important analysis tool in fact and then overlay analysis as I said for example I have the soil layer I have the agricultural crop layer so if I overlay agricultural layer on the soil some area I am seeing crops are very less production is very less even damage there is no production almost zero so the reasons you can find out why these crops are not growing why the particular day is going very well you see the based on the soil for example I am going cotton crop I do not have any black soil I have pockets of black soil but where production is very high because cotton crop needs black soil is suitable for cotton crop similarly paddy having this different crop horticulture crops when you grow all clay soil will not support so we when you do this overlay analysis you will be knowing the particular area suitable or not site suitable analysis is a multi right then which side is that suitable which soil is suitable for particular crop that you can find out when you access this overlay operations like this and also existing already happening why it is happening why not good why not bad right that also you can see when we overlay one upon another and also it will help us to find out the seasonality overlay analysis also will help us seasonality perennial the particular water body is perennial or not you can see when you overlay the same layer in different satellite images team series team right temporal data yeah these are three types of again overlay you can do point to point cooper overlay karsak the point line cooper karsak the point polygon cooper karsak the line polygon cooper karsak the polygon upon polygon also you can do but not polygon on point remember always special data will be when you go for overlay point line polygon this is the hierarchy or ordering right always use this special analysis tools point line polygon this hierarchy should maintain when you extract data when you analyze data in jas environment never be polygon on point always point on line point line on polygon can be done with polygon never go on liner point which you cannot see the special data right so this way always you have to do you can see even in analysis of the vector data point on point point on line line on line line on polygon point on polygon polygon on polygon but not polygon on point or line right these three ways that analysis and lastly we have the surface analysis and we have one more network analysis surface analysis like how your physiography look like as i said no digital elevation model there's a map exactly how your geographical data represents right this particular portion is elevation how much how it look like whether it is valley land or plain land or hilly area that you can see exactly how it look like the entire geographical area study area using your surface analysis we have gtm that is digital terrain model we have digital elevation model right then we have raster and vector both the models like tin we have as a vector surface analysis tool triangulated irregular network using contours it will generate contour you are aware no contour is an imaginary line with this equal elevation same elevation right it will mix wherever it same elevation goes like way tin also be generated in vector form using the surface how it look like exactly then last one is network analysis in gis in special analysis after measurement after buffer after vector analysis after your surface analysis you have the network analysis these network analysis basically used to find out the shortest path for example i want to move from here to for example say kamaki temple so which way is shortest path to reach the kamaki temple from this point which road you should take which is the shortest path to reach that there are different in network analysis also shortest path best path analysis of course it may be short but you will not reach in time which is the best path again to reach that particular destination right and basically the shortest path analysis at network analysis we can use for transportation and also irrigation drinking water all linear features road networking right will be used this network analysis as i said drinking water source is somewhere else but i want to give different outlets for water drinking water households or community taps on the road side then i should know what is the shortest path to reach that source to the village again within the village which are the locations suitable for giving the outlets of the drinking water tap that exactly can analyze like this which way because gs also having three-dimensional view the elevation also will come as water goes through the gravitational force the elevation also will be known and also the exact point line polygon position will be known with the gi system so it will be shown which is the shortest path how it should go how you will reach the destination from your source or origin to destination these can be identified from the network analysis this network analysis even health facility like ambulance services and all they are using to reach the quicker shortest path to hospital and also to your accident place like one zero eight service i think in s m we have no one zero eight yeah once you call one zero eight they ask where accident happens simply they enter the in the google earth the latlong they have the old network roads data ambulance which is the shortest path reach to from ambulance place to the accident place again they also enter the accident place to reach the hospital what is the shortest path which is the shortest path to reach the accident place to hospital will be found out through this network analysis they use the gis right they are demarcated they see right accordingly they follow it so this is the all this is all about spatial analysis we have in gis this is my final slide of the network analysis and if you have any doubts questions you are most welcome now one is spatial data processing like what is vector what is raster what is point line polygon how data can be generated how data can be extracted right how what is the georeferencing how data being extracted i mean scanning or distilling then editing so there is all database creation what kind of data what kind of spatial data models we have in gis like vector data model raster data model and then once you complete the mapping process then you are coming for spatial analysis right second unit in the special analysis different special analysis we have query measurement of the geographical features then surface analysis network analysis these analysis are very very useful for planning or monitoring and evaluates any scheme which you do analysis is very important that should know through the special analysis this gis or special analysis will give you not only quantification like a table it will also give you the picture pictorial form where is what how much it is right both you will see simply telling that we have 100 actors of agricultural land know that normally without gis you see in the table or from but in gis what you do in special analysis where the 100 actors of agricultural land you have in your geographical area will be shown in different color that is the beauty of this gis right so such a way special analysis will be done where people will understand reality without going to the field they will understand really this much is there this much is there this much is there so this is the gap where we need to think plan for development of the area fellows are more there is no drinking water unirrigated area more right how we know through this special analysis only once use a special analysis once it comes to the pictorial form the authority will easily understand a layman can understand really where the gaps are there where planning is important right for that your special analysis tools will help us to authority to give you approval concentrate and do the scientific planning in a scientific manner one can plan exactly where things are required facilities assets are required needed in your geographical area right there is no scope to i mean what do you say escape exactly what is there on the earth one has to tell through the map and the plan accepting or referring to that also you should know where is the gap where we need to concentrate for development two things will come in the visible impact which we can see with our eye right there is no chance for duplicacy overlapping etc when we use these special tools okay thank you
