What’s mobmap? Input Output time-series data(CSV) Route data(KML) Movie(MP4) Mesh data(CSV) Polygon data(KML) time-series data(CSV)

Why Mobmap?

When visualising time-series data,

Export so many many PNG imageries and create GIF animation.

Take so much time and have to remake again and again every time a new attribute is added.

Play Mobmap 1 There are "Play", "Stop", "forwarding" button like a movies player. Each object begins to move when the “Play” button is clicked.

Play Mobmap 2 Following four attributes are necessary for using Mobmap. "id" (user ID), "date" (time information), "lat", "lon"

Our theme • Where and How do people come from? • How many people go path a road ?

Path Visualisation Change ”Dark” color Check

Attribute query In the case of plural conditions OR sentense（or） AND sentense（and） category=4 || category = 8 category<4 && category > 1

About spatial query Deselecting select of the polygon select of the rectangle select of the line gate Choose a movement object from the select button of the upper part menu

Export Mobmap can export trajectory data as well. Link data also can be exported as mL format.

Animation export By the default setting, output a share for ten minutes in animation reproduction one second. eg: In the case of 15sec, it is 150min

Visualise abnormal event 1 • With Person Trip data, Mesh data becomes like this

Visualise abnormal event 2 You can check population volume in time series and an abnormal movement easily.

Practice data① Simulated People Flow data

Practice data① Simulated People Flow data Simulated People Flow data is made from geo- tagged Tweet data (presented by Nightlei Co., Ltd.) I'm at Ramen Jiro Meguro shop (Meguro-ku) 139.707142710686 35.6341373645078 ex)

Practice data① Simulated People Flow data morning and a holiday. Finally, the place is (cooperation: Hiroshi kanasugi, People Flow between check-in places using road data Paths are interpolated based on the places of the check-in (movie, amusement, etc) Virtual stay time is set in advance per category determined at random in the city. which users have frequently checked in on This data is created as following estimation and interpolation methods Home place is defined as a city and district interpolation ・Path estimation ・Stay time ・Home estimate from geo-tagged Tweet data. Team at Tokyo University CSIS)

Raw geo tagged tweet data on a map (without the interpolations) Step1

Home place and stay time are given to geo tagged tweet data according to the check-in on map (night-time). Step2 Virtual stay time per about 250 check-in place category

Paths are interpolated (only in the road) for creating Simulated People Flow data per 5 min using INFORMATION PLATFORM FOR PEOPLE FLOW ANALYSIS by the university of Tokyo CSIS.

Summary Using Mobmap, We learned the method to visualise and analyze GIS data with the time-series data. This exercise provide for simulated people flow data as sample data. Also, you can handle your own data as well.

Request of the questionnaire http://goo.gl/bwgCcl Please answer following questionnaire to improve Mobmap and hands on in future.

Thanks For creating data and this exercise, Hiroshi Kanasugi helped us to interpolate and create the Simulated People Flow data. The Simulated data is made from the geo tagged tweet data by Ishikawa, Nightlei Co., Ltd.. We appreciate them.
