 Geographical information system for agriculture applications, now we have been talking about what was the different methods, different data sets which we have which we were using it for the past so many years that includes your cadastral map then rate card or ROR that is about your farmland activities then topographic sheets and further on and there were problems in knowing what is happening the rest of the area in addition to what you are looking for. So and second thing is there were no references with reference to whatever they have surveyed. So now there is a need because of the global climatic change and other things we need to know what is happening in our field as well as in the adjoining areas. For this purpose we need to georeference the or we need to look around that all the data sets in one platform and then integrate it analyze it and then get a information. For this purpose we were trying to use the geographical information system is being up is useful in doing all those things in type analyzing it in space in time and other activities. So now we will just get into what are the different aspects in the geographical information that we could use it for the agriculture practices. Geographical information system is a system designed to capture capture in the sense wherever it is however it is the data could be captured and stored in the computer and the integrated data could be manipulated in the sense giving to a common reference system of mapping and also you can analyze as well as manage the data set and present all type of basial or geographical data. So these data they are all location then based on the locations on the earth surface which has been recorded as a x y coordinates as well as z coordinates that is the vertical coordinates representing the longitude as well as latitude and elevation respectively. This portion can also record dates as well as time of the occurrence of the any event that we are going to record on that surface. Now if the earth paste has to be a spatial temporal and locations and it should have ideally related to each other. So that is what the geographical information system if you look at the geographical database what is the system geographical database which we have got we have got one set you have got a thematic data in another side we have got a framework of data. Now thematic data which basic thematic data comes from different sources it comes from the aerial photography it comes from the digital elevation models which has been done by the topographic sheets and also it has come from the different landowner records and transportation network like that we have got a framework of data and these data sets they can be integrated in the sense whatever the information which you wanted to do it those things they will be able to overlay each other and thematic information is the nothing but it is the output which you wanted to present it for a geological or it is a decision making purposes. Suppose now we are interested in the flood zones if you are interested in making out which are the areas which are likely to be come under flood zones during the activity. Now the functions also there are several functions one of them is input from how you give and where you take it up manipulation it is adjusting the data types to a common platform management and query and analysis nothing but it is what is the information result like the thematic data which you wanted to do that could be done visualization is possible either in the form of a map whether in the map of a turbo or either in the form of a P chart and other things so that your results can be presented to a decision making bodies. Now another view that we want to just to see that is the different layers one thing is this is the data these are all the geo reference points on either side of on all four corners and this is captured and the road network is given over here and here it is position of the various structures on this side and vegetation cover in and around as a separate layer that has been done over there but in after integrating all the things this type of information what you are likely to get is the one where you have a road where you have the actually it is nothing but what you see each on the reality content. So each reality content has got a relevance as an attribute data this attribute data are given over here in the form of a different features and what else and it is the address and it is IDU code. So then in this way what we can do is different type of data layers can be merged and you can say and you can visualize or you can project it as though what you see it on the reality things. So what are the different type of data set DS which we can use it one thing is a desktop data so wherein you are the software is installed and runs on a personal computer on the side the another one is on the web GIS this is for an online GIS applications having data visualization tool is very good in this category. Another one is what all of us are about all of us are about or know about the Google Earth images maps and other its own thing the Google Earth what you might have done it the road network and road network then you can superimpose the satellite data and you can select where all the places which are available like restaurants and other bus stands and so many things which you are able to see it those are all the things are known as the geobrocessor data that is also available for our process. So these data sets what we have got is nothing but this is how we will be able to use the geographical information system on a different platforms and it can be given it for a different information or different decision making bodies that is what we wanted to show it as a short presentation.
