How to register and set up survey data

Introduction

This article provides a detailed explanation on how to register and set up survey data.

By registering the survey data as the pre-construction topography (reference topography) and inputting the design data as the target design surface, it becomes possible to calculate the soil Volume.

In addition, by surveying and registering the topography as the construction progresses, the overall progress can be calculated.

Procedures and Explanation

1. Click the 【"1" Add data layer】

2. 【"2"Upload survey data files by drag & drop or from a local folder】 and click 【Next.】

If two or more survey data files are registered, they can be automatically merged.

3. Register the survey data as preconstruction terrain or survey data.

1) Select "Survey" for the registration data type.

2) Turn ON 【"1"Preconstruction】 to register as Preconstruction Terrain (reference terrain), and turn OFF 【"1"Preconstruction】 to register as survey data.

*If the pre-construction terrain (reference terrain) has already been registered, the above items will not be displayed.

3) Set a timestamp (date and time of data registration) as the time of registration and click 【Import.】

If you wish to use the detailed settings, please refer to the following.

Supplementation

• Preconstruction terrain (reference terrain) Flag

【"1"The flag icon】 is attached to the survey data registered as preconstruction terrain (reference terrain).

• re-set  Preconstruction terrain

【"1" Set as pre-construction survey】 option will appear in the Surveys menu display. (*It will not be available for survey data that has already been registered as pre-construction survey.)

After making your selection, the following screen will appear. Please confirm the reason for the change and select the 【Submit Change】 button. (*The following image is an implementation image.)

After selecting the 【Submit Change】 button, the re-tiling process will run.

• Change the display style of survey data

You can change the display 【"1"style of survey data.】


Points: View point cloud only
Mesh: Generates a texture from the point cloud
Both: Displays both the point cloud and texture

Points　　　　　　　　　　　　　　   Mesh　　　　　　　　　         Both(points and mesh)

• Point cloud edit
  The calculation process begins as soon as unwanted objects are removed from the topographic data.
  
  Attention.
  If you edit terrain data, the calculation process will take an enormous amount of time.

Please refer to the following for the procedure

Adjust the data to an aerial viewpoint in advance, click 【"1" Survey edit】 and select 【Add Point Cloud Edit.】

• Object remove
  Click with the left mouse button after enclosing the area, right-click to exit.
  The area to be removed will be displayed and then processing will begin.
  
  
  

Attention

This function is not intended for removal of unwanted objects on slopes.
We recommend to remove trees and construction equipment on flat areas.

Supplementation

You can change the transparency of the Base map and the priority for transparency of Base map data and registration data.

• The transparency of the Base map
  Use 【"1" the Opacity slide bar】 to change the transparency of the base map
                                            Before                                                          　　　　　After
  
  
  
• Switching the display priority between map data and registered design data
  １）Display of design data lower than map data can be switched.
  Prioritize design data　　　　　　　　Prioritize Base map
  

２）Allows you to switch between displaying survey data that is lower than the map data
     No consideration of base map　　　Merge base map height and data

３）Checking the 【Fade by distance】 allows automatic adjustment of transparency display when zooming in or out
