1. Overview
You can download all the data in the area selected on the map. In addition, it is alsopossible to download statistical data with contour table or graph.
Rectangle :Suitable for a wide range data downloading at once.
Polygon:Suitable for a wide range data downloading without unnecessary data.

Line:Suitable for data downloading with detailed route and drive direction.
And you can also download statistical data.

Different ways of using
When selecting an area with “Rectangle” or “Polygon”, data in the area will becounted regardless of the direction of travel. Therefore, if you don’t want to include
another direction data at an intersection, Using “Line” is the best way.

2. Three types of Area selection
Rectangle
Click two points on the map to select the Rectangle area.
①Select “Rectangle”.
②Click two point on the map. (Click diagonal Rectangle.)③Select “Data download”④Click “Analyze” button.

After clicking “Analysis” button, Rectangle area is displayed on the map.
The data in the Rectangle is downloaded automatically.

2Polygon
Click multiple points on the map to select the Polygon area.
①Select “Polygon”②Click multiple times on the map to draw Polygon③Select “Download data”④Click “Analysis” button

After clicking “Analysis” button,
the data in the Polygon is downloaded automatically.
To confirm Polygon area on the map, you have to double-click on the End point.

3

NOTE. How to modify Polygon.
①Click “Modify” button.
②Drag vertex to move.

4

Line
Click multiple points on the map to select the Line.
① Select “Line”.
② Click multiple times along the route on the map to draw Line.
③ Select “Download data”.
④ Select from download type.
⑤Click “Analysis” button.

After clicking “Analysis” button,
the data in the Line is downloaded automatically.
To confirm Line on the map, you have to double-click on the End point.

5

NOTE. How to save Line drawn on the map.
If you save Line, you can draw the same Line on the map again.
You can use it when you want to continue analyzing on the same route section.
① Click the “Save” button.
② CSV file is automatically downloaded.
③ Click “Read” button, then select CSV file you’ve downloaded.

The CSV file records the latitude and longitude of the click point andthe distance between points.

6

NOTE. How to modify Line.
①Click “Modify” button.
②Drag vertex to move.

3. About contents of Download data
The download content differs between “Rectangle” or “Polygon” and “Line”.
Statistics data can be downloaded on "Line".

3-1 Download with “Rectangle” or “Polygon”
The downloaded folder contains three files.
1.Section.txt: The data of index value (IRI, Linearity, Crack, PCR etc.)
evaluated for each section

2. BumpIndex.txt: The data of step height under the spring at the specific point. (Themaximum depth when applying straight edge to the road surface .)3. BumpData.txt : The data of step height on the spring at the specific point.

The contents to be downloaded are roughly divided into three groups,
and five download types are classified.
A. “Individual”
You can download index value (IRI etc.) of all data in Line.
B. “Monthly” / “Quarterly” / “Annual”
You can download statistic data and graphs of index value for each sectionin Line (in units of monthly, quarterly, and Annual).
C. “Total”
You can download statistic data and graphs of index value for each sectionin Line (in whole period).

A. Individual
In “Individual”, two files are downloaded.
1. Section.txt: The data of index value (IRI etc.) evaluated for each section.

2. BumpIndex.txt: The data of step height under the spring at the specific point .
