About this app

◆Anyone can easily create the coordinate data necessary for positioning with just a tap on a smartphone

You can create the coordinate data required when using Topcon's positioning system "Rakusho" and "LN-150 Pile Navi" at construction sites with simple operations on your smartphone or tablet.

◆ Connecting the site and design “easily” “3 easy steps with your smartphone!”
Step1: Import drawing data (DXF format)
Step2: Tap the point you want to locate
Step3: Load the data created in Rakuza into Rakubumi and start positioning!

◆Using Rakuza, you can do the following:
- Reading and viewing 2D CAD data (DXF format)
- Coordinate transformation for measurement
- Extraction and registration of measurement points
- Output of design data (CSV format)

◆Recommended for these people
- I don't know the "coordinate" data
- Want to save labor at construction sites with the latest positioning and surveying equipment
- I want to perform accurate positioning according to the drawing.
- Want to advance DX on-site and graduate from paper drawings
- I want to work on site or on the go instead of in the office.
