Historical land use records are valuable information for biodiversity protection, disaster management, rural area planning and many other uses. The Rapid Survey Maps (RSM) that were surveyed in the 1880's (early Meiji Era), are the first modern cartographical map series of Japan and important sources of information on traditional land use in early modern Japan. We had been analyzing these maps based on polygon data and raster based Web-GIS System to disseminate the Rapid Survey Maps using FOSS4G, but, these are difficult to apply for quantitative analyses of land use change. Thus, we developed a grid based land use database using QGIS and PostGIS, and published the database using GitHub. First, we developed a land use data input system consisting of a client and server. The client was developed using QGIS API and the server was a PostGIS database. Point data as a 100 m grid was stored in the PostGIS server and land use category underneath each point was input using the QGIS application. About 1,400 thousand records (70%) have already been inputted. Error of grid based land use data is less than 1% compared with vector based land use data. We analyzed land use change from the 1880's to 1975's. The most significant difference between the 1880's and 1970's is the area of urban land use and rough land such as grassland and bush. Urban area increased remarkably and grassland area almost disappeared. That does not mean grassland changed to urban area. Most grassland changed to agricultural land uses and forest, and urban area was formerly mainly agricultural land use and forest. Some inputted data have been copied to GeoJSON and uploaded to GitHub ( test/) as open data (Creative Commons BY 2.1 Japan). A tentative data browsing site was constructed with Leaflet (for example, test/rapid544000.html). In this site, it is possible to compare point type land use data in the 1880's and present topographic map/RSM raster data. We hope that this database contributes to not only academic research, but also business, government, and public interest.

ns then OK good afternoon everybody
it's nice to have to talk about the uh my research turtles a presentation to developing them and the students in my lectures this book have that I have found and and regular world metals due to elaborate sensors in those so the the nearby woods of analysis of and me was a foundation Japan's chapter and this is an a of around to this paper petitioned right past I'd like to me expelled both of us that the background and will this that and the development of the land is made of this sort the promise of this development and the allowable obligation for the round is just in variations in the defined by Iacocca about separation that it out of integers so in fact I have to have to hits relevance the progress of the historical information it just when we go from the no money coupled in digital signal it just shows that our institute announced attention to pick the most people as well as an effort to the uh France because that by type communities for artists from here that theory on this picture will be the only depicted in this area this means that it means that the broker in the bag and so were they found that in that come to visit these areas then this you the blue crab that area is rather area in our about society correcting units to be a set good Kyoto was added to the but rather like this and in this series of enzyme mediated handcrafted coming to that hinder the path from the very top of the roof if you have a will be can compare these of them after this is over the market in the ninteen eighties eighties and this is that the you see the in the photograph after the 4 that we just need the area in that so that's the other thing that's a fact FIL sort presented in here I can see the center
of this you so so this really is about the future in this area is this year grab means that the predators that that food of the pattern field is contrary to the spirit but it's the front but for instance of
begin but the human hearing that can you hear the term means not much affected so that
the concerns that path round is very important FIL disaster mitigation and here I have to explain about the so this month the In this number is accorded that it's not enough being in southern in that our major interest it's not a name used to in the sixties the enactment salvation of needs in the Knesset forms of measurements of mRNA so that the and often in the model a of the market in this rule this happened in the Internet this In the rest of the country and things the produce here are Institute here and this can only well what the 2 in with the 20 cells that and 900 marks the talk was about member of the Mende 900 here in this in the value of the material the so this is the wrong in that case you need grab 7 they can use it with another set them up in the that this class about then we can see here the crime means there are influence In the green curve means being Lutheran or 1st in this kind of is so all round that Brown had means that any advance fees In here flows a telescope that this means pi and you can really can affirm their uh what species know this is this is all the fast it from his mother and also here the some kind of the skip keys fit of the runs gets you again InĂ¡cio while others such a yes no and escape from this much but it does have some problems in mind said today's this is a the this is the this let's use it in their head bad debts and openness in to Japanese and the D. assigned University Institute but no jubilant suspicion information of the object is at the things in it that Japanese marked and so that that's the exist so is the set but the model only walk hundreds 16 In the event that his thousand that's so if this is good so a eliminating in the lead in the try to make a summons and the web service systems do this thing with this of the in the end is is in it known people in using this is not a not for their members and the landscape changes in Rolf example runs the official I should they conducted on this educational support to let you know in each got here from the from the city come humans industry and they conducted under city which who in grammar is 1 of the few and the me Aiken extensible suffuses that in is In the present study is only limited areas that you nominals whole around this changes in country years so in a way are always it is through this study is to be developed that animals and the status of this paper is a bit appear quantifiable down this database the where where the developing submitted systems so that here in the but see them up as an it but it is difficult to evaluate to understand your some some so that now we try to make around this data is in this area and we tried to Palestinians in the this database as a of the game excuses new fast roots we try to conduct the 3rd in the story of a little bit optimistic around databases and the conducted accuracy assessment so in this study we got him around is database as the walk internet that good and the date that this what was the person assuming the progress that you make that uh now this status and that is that the moment that by and get back to community no time so that we use this kind of music that presents background is that there is if you individual at the time of the Big Bang to suspend the use of force the that was really the inteface use still at the back you'd use and CPI and about the disease said on the same is developed by hearing the use of the possibility to and posture in some I just to
show you the the you the that is so you know the point speakers In this column there's a lot of time on this I find find these views on the chosen units and we really need that in interpreted the obvious under this point for example the city here is that there are a few so we you now for example notice if you read game the the sentence from the theory 1 of the inventors and in next at the very end something like this In the instinctive it it
and of deserve the only make our of these with the the and after the details possibly conducted unjust assessment you got the point that there is in the Rhapsodie just made the in to map the data marketers of illegal computable that this around the state fair and is kind of the point of boosted on the status this is that's always the grade book evaluation if this is the on this here is yielding 241 because to this this means that point I'm going to the point that they're going status almost the being the the united iteration almost same so that's it we consider in a dependable back in accuracy is viewed as a for this analysis as next week when the around in the in the sense in the style that and they are both there are worse that input that the data will talk language use the runners medicine and other than thing he did that has already put it and were suddenly in we provide in we explains the understood in this new areas I'm here we compress the some the and at the end of the 1980 75 right i so it's the medicine defined this period here maybe in inference in maybe under the influence although Japanese hypothetical impact yes this it is that there was obtained from lesson around Munich Information neutral is acidic methods which this enables that that I would like to get us into the computer and the data and wanted to be 2 data's this is the result so we we we display to the patterns of France who throughout the aggressor in militant and about it and what areas in West Sumatra exchange is what aggressor residences these also vanished and here in the other area is includes 3 In other words show them out a new amount then implement these the of units of the so so read in In the terrorists the degree of all of the graph and inclusive was there and that that is the display shows so that that means grasslands change is I about areas so in this no the grasslands indicated this orange cast that eating the big difference so that the person that's still means to explore the association and this is really a constructed graph that area into user name this orange cast into this in the colonies of the marsh grass and under the latest in the restaurant is distributed through the future was a man in or are that means they all right to areas and this includes the members change the the grass on any of its changing to reach strongly is the green means the thing forest in the room are means that a branch so most of the graphs in the field area they change into the area cost in most of the restaurants being the front to in in in the user area from theUS and I'd like remove have about the numbers optics and nodes in the of the medicine is In the 6 in 16 6 passing of operand fields instances of iris and to points all the forest India through the and feed into an institution plants and 2 of area and there is a up their food and fast is degrees of from any authoritarian In the is through the 1970 is but the greatest the of fields and the 1st area is coming that in come like this you find a restaurant the and also it this is a kind of some of the diagrams in ruled the age power uh let alone is changing the country area yeah method influence is the use of so many questions and that means it really a but register unconscious time knew that you needed restaurant move people follows a factor is that where the material was a that of a material a housing nonsense exact that they default they are routinely analog media that cuts system is changed in the defence they change it was that for this changing in that in the have to pay the taxes based on the production or was so the products or something like that but after after the the system is changed to have to pay a community-based answer and a around area so that they don't want to use the grassland residence not engage generate more money so that changes a fast walk up transfused if that test is positive if you you just use up front view to be equals its fuel flow revolution in factor the Revolution note that this chemical fertilizer become a popular in Japan in the 90 sixties the so that question is the branch future don't In Advances in the public fuse and after that so in the other so many In a letter to economical growth and map each in a publishing increase in the use of around this desire areas that the future in in the park in the population now is decreasing and it to the air copper here are on this in 3 dimensions so that the future is not clear about it we can conclude that the driving force is defined each time this video yes and develop and assume that students and with a bit better the computers assuming the fact that the people in in Paris too big enough that it back answer in In the what it is you can this form of them moved back into apart source and that that's so that you can knowing the the they use that we use a distance so mentions and also the code to data in doing that it in this research we already up some part of the data that in the real world uploaded to the hip-hop of the the food and the the you may think that the
in you can see that you do so far and you here family and well so you have to go and yeah is the that's the 1st digit those videos that to understand what what kind of the round the he here so that we offer from the developed as reusable
about certain the playing live side of this program on the use in using is in effect all so you you can click on you don't ships around the user in through because soaked the background you could do this a this kind of the
In because that is the in previous amount that this area of regional data we just read which you know things yes the
and this In the conclusion so we could look that this is that is that the government and the point is that and I that's the long 9 90 per cent have been included and that hurdles upon the data on labor force that is aligned obvious changes may be a little conducted to understand and allows for the use of the country region and then we can see that the drastic around these change in special interview distributions across and and and a subset of the points left it's hardly published as other Open Data as and so it it's method is also used it that is that we can comments back and in in the preprocessing so in previous studying in we published in that it said that not enough the data as a way to do it as an independent marketers need is that the parameter T 2 additional was an absolute not let them with the prophet the that so for individual interests present interest the sometimes people using the to snorkel rosier made that have some that in the hope that this that this also contribute in this initial of let's have another future utilization of the new form of means such that the support of public protest or sediments and how the we have unwanted to questions the tool quest interests and the both 1 lady seemed Ballantine that it had been a point the foot in gradient all you just look at 1 point in the filling type 1 or 2 if you do happen to read you seeking the point made you'll you buy the land use note just just 1 line just not where writers of the and then you have these semantic FIL of a there was 1 change all the
story semantics was 1 that I go day in this this is the area
of of the things in your right the on collections of findings are wholly copied into these conclusions on the companies continue trying to cast the sole means of the ability of the ball in the year and that are applicable to all those that that's the depend on the those applicable but then is to assure that history constitutional news for example in that is part of the 2 is relatively what it developed in it being a hundred years ago so the this remainder and that as a total to area you have to be given off and so that there was no that at all of the devices to get a good sense of destiny is only banished in all the graphs and changes the 1st the operands it is yeah so that would be spent on there being in the intervening years host cells not the only thing I in a in a whole other areas and that's the end of the the sequences of the MIT is similar to the properties and would this is this search this happened that the photos that was and he surpassed where no nobody but the area this sequence is it applicable for the about to kill but unlike in that the this happened and that's about 100 years ago that this happened in about 100 years and equipped with the to add in patent total but after that it after then for example 15 years ago Philomena happens in the province as he would like his wife you who we are and what you have to move on so that we can stick to us and we can you for rest
