This article aims at dealing with the inconveniences—associated with places—the foreign tourists are experiencing by utilizing the big data technology. It analyzes the spatial density of floating population of foreign tourists and suggests a variety of applications based on the results. This thesis associates the roaming big data of foreign tourists with Geographic Information System(GIS) to analyze the floating population density by location, time, and country. It uses R-Studio, a statistical computing software, and QGIS, an open source GIS software to visualize the data on a map. The first step to conduct the research is to open CSV format data and set variables for analysis. Then it analyzes the spatial density of floating population of foreign tourists sorted by time, location, and country, and the number of visitors is ranked for each location. Based on the analysis results, the data are visualized on a map through QGIS. Lastly, several adjacent target points—base stations—for certain locations are matched, and the necessary data are sampled out of them. This paper selects fourteen locations whose floating population of foreign tourists is dense: Gyeongbok Palace, Namsan Hanok Village, Deoksu Palace, Insadong, Myeongdong, Namdaemun Market, Dongdaemun Market, Garosu-gil, Apgujeongdong, Itaewon, Hongik University Entrance, Gangnam Station, COEX, and Lotte World. Moreover, it categorizes fourteen places into historical, shopping, and complex attraction and delves into the pattern or characteristics of floating population according to the categories; the categorized results directly show the distinct preferences for places and visiting time period. (Although the names of the countries the tourists are from are not provided in the roaming data of foreign tourists, they could be readily inferred from the comparison of the analysis results to the survey conducted by Korea Chamber of Commerce and Industry.) This research paper makes four pragmatic proposals in order to alleviate the inconveniences regarding the signposts, bus route, and insufficient tourist information centers; it suggests to add languages in the signposts for certain locations, modify the current route of the city tour bus, and build additional tourist information centers in several sites where floating population of foreign tourists turns out to be dense. The degree of correspondence between the analysis results and reality is examined via field inspection. Recently, tremendous amount of data is produced and open to public, which leads to the enhancement of transparency. This article, which connects the big data to GIS technology, would be one of the significant cases of effectual spatial decision.

and but now and again but the along
the lines of Wiltshire Professor drawn to their pronounce it right and fellow participants no audience I'm very honored to present my paper analysis of spatial density utilizing the Big Data of floating population of some city in the academic track the 1st 4 G conference In this presentation I will be 1st mentioning how and why initiated this research the that have been focus then the title and I'm and throughout the research the software I use for the analysis the procedure through which conducted this analysis of the results of the analysis will be demonstrated in 2 aspects 1st on and I'll provide you with a view of the spatial density of foreign tourists and solve the and further down into the 5 significant areas with the analysis results are not that in the latter part of my presentation I introducing new applications based on the results of an office currently but there was a
rise to support spatial density other special diffusion more efficiently and there are 2 cases that proved that 1st use would be such metropolitan governments all so it is operating on best-first thing passengers it's sniper service focuses on joint optimum bus route from the center the grounds for appropriate locations which are the bus stops and time travel between bosses
moreover that there was used to fight against crime publication shared information combined with the data from under local authority social services and intelligence gathered by the beat officers is helping the police forces around the world to spot tried that before it starts while previous researchers have used either come back and historical knowledge or the on offenders profiling the missing researchers presented another approach to predict the crime in a geographic space than multiple data sources in particular mobile phone and demographic data however current tourism industry mobilize and so these are all simplistic statistics we are smart phones and social networking services are producing significant data which it can pass this large amount of population the
fabulous admin looting and into dead for interest in on culture heritages and Korea independent or obstruents expressed a inconveniences and possible such fundamental problems is significant for crew whose number of foreign tourists is referring to increasing yet revisiting rate is still remains strong so I want you to a Amy research that on provides
that those and scientific spatial decision with this statistic and geographic means and that the use of learning the French West and so the on the but such interdisciplinary approach the analysis of interest uh is conducted in 2 variables the location of the country where the towers of from and the time period the combination of those 3 variables at the time the spatial density of Franklin population was drawn which enabled this research to contribute to dealing with the contents of and visitors of so the the so the remainder of the analyzes and this research was provided by a 12 bit announces contest it contains 1 million 773 thousand 618 variable users registered in 1560 cell powers of 30 I 1st used by the student to statistically analyze the up into jurists an open-source she geographic information sector system software on 2 instead of statistical analysis results on the map of the city the 1st step of analysis is
is set workspace instead necessary packages but in the hour studio In this paper the package deductible is used since it's useful for fast aggregation of large amount of data that and there's fast on arrangement arrangement of columns with in the table and then the number of foreign interest in CSV format is are important the that is further analyzed the organizing several columns consisted of combination of variables I the time our country codes that latitude and longitude the the statistical analysis results are visualized on the map in transformed into a heat map which effectively shows a floating population density by points did you points are matched to a certain location and sampled to indicate the spatial density of 4 1 hour twist within the within the area as mentioned the child of a number of foreign tourists as 1 million 774 thousand 618 and this heat map represent the foreign phone population of and assess the inventories are mostly concentrated in come together at the area above the reference and sample of memory the level I this table shows the number of foreign mobile phone subscribers a sort of a nation the Association halogens visitors from country and and the person and so are the 2nd most we have a special benefit analysis by time shows the obvious results that other person 10 to the 4 PM and post and have has most 1 twist and this is a jet of spatial density changes according to time this is a table of numbers
interest information areas within the society sort of the country and time and
this is a coach Edward don't require presence greater number of population among these affected by various i'm because
announces results were notable 1st come the
past the disposition after time
EPA's screwed into GIS the points marked with up and that contains the information of latitude longitude and the cumulative number of foreign tourists after adding adjacent points it turns out that
the on the moon and the poorest from country in 1 and its visitors are concentrated most during the time not considering that it is a historical attractions moving on to the
market as many visitors are the Twiss from country and 1
and since it is that market on item from a plan to to him is the most current time but the next the spatial density of the
optimal in common area below the river is not really the and then there are no twins attractions and it showed that certain
populations with the proposed from
country and In a sense out that this a is
renowned for the past history planets on which contributed to Chattanooga more interest in Korea for the purpose of medical person on at that location is unlike
the locations that is to say that verse
from country and so and 0 6 and intent and the of most frequently reported to the cell tower near you tell and
lastly time University all that
goes from hopes of country and around a conflict good as part of of its French words of prose various nationalities were found and fact shopping streets and nightlife establishments demonstrate the hectic spatial connectivity patterns so other some
statistic analysis entwined with geographic and social approach on here I made for suggestions to solve the inconveniences that too often entries are frequently experiencing the are the 1st serious establishing additional press information centers so cruel and all
credit to 5 times information so centers within the within society but
on 25 20 seconds are concentrated in kind of a questions analysis results hard to win over the
phone to his income and that the the the energy that depends as well there's additional POS information centers are required it suggests 7
% in the output of In the appropriate locations this application is about the
Signpost the current trend of Commerce and
Industry so states that 34 the % of tends to us and we want when 3 % of japanese tourists experience the inconveniences regarding the Signpost although handwritten Korean English so and don't know the exact meaning of the country which is the country code was not specifically mentioned in there are enough women but but you can easily infer that supposedly has its most those visitors from China and Japan based on current all present trends of Korea 7 a sense based on this spatial density announces results and our current to his friends of career at all are you can be already inferred that the sample is written in addition of foreign languages other than Korean and English are required couldn't answer is
operating still to address in common area at the at the level of the river however the
spatial density of of the population bandits simple all of their current is mood is in fact an efficient so I'm not the word into the evidence for the population of interest westbound the
lastly i I'm proposing that the service so our although science and is operating at the Beresford saying that patents are there were some inefficiency revealed in us and part of the current route so based on the the
spatial density announces of in population I noticed on air and I noticed some air all areas in locations that then falling population and links such areas but in the new route of nite the service which you dominant enhance the efficiency of that that the service system for the of point process well so are recently a
tremendous amount of social data that is being produced and open to public there's a prison industry would have to utilize such on large amount of data big data to provide customized services of 1 trees which would attract more and more as twist art to Korea and this academic paper would be a significant example diverse and scientific spatial decision that some utilizes a combination of statistical did they like and geographic information system technology thank you very much
if if the of German questions yes and the confidence of underlying almost nothing has been agreed with the reasoning of I just survey could because some of it you get your data and home commented that you do analyzed and so I the action measurement presentation that there are this roaming the that I was provided by that was again announces contest on and this state is actually from as key key thing is the creator a maybe like so passes them unless and I the data contained 1 million 774 thousand 618 individual level of often users but being further questions so for the a pain being given a much
