Dajiang Zhitu and CC have produced multiple copies of data. How to combine them into one and load them in the new earth map

0 Source of problem ：

Drones are on a certain place Subregion Data collection , Through Dajiang Zhitu or Context Capture Build the tilt model , Multiple tilt model data files will be formed . If the amount of data is large , Loading one by one will be troublesome . therefore , We need to merge and load multiple tilt model data .

The most suitable method should be to collect the data in different areas and then make a whole model , However, the actual situation often requires more urgent data , Once collected, a model will be produced , Will not be put together for empty three out model . As a result, it is clearly a continuous region , There are dozens of tilt model data in your hand .

1. Principle analysis

CC And Dajiang Zhitu modeling can be set Projection 、 Coordinate origin And the of the model Block size

Just keep these parameters constant , Of the final generated data metadata.xml The documents are exactly the same .

about metadata.xml Completely consistent tilt models can be merged

2. Solution

2.1 Dajiang modeling data consolidation

from 【 Great Xinjiang wisdom map 】 The model we built , Every terra_osgbs The folder contains multiple “Block***” Folder . The new folder is named “Data”, Each generated by the big Xinjiang wisdom map “Block***” Copy folder to “Data” In the folder , And will xml Move the file to the new Data Folder in the same directory

  If there is only one tilted model exported “Block” Folder , And the same level directory also contains a “Block.osgb” file , You need to “Block.osgb” Files in “Block” In the folder , And its name cannot be modified . The new folder is named “Data”, Transfer multiple data “Block” The folder is in Block Add different suffixes based on , Copied to the “Data” In the folder , And will xml Move the file to the new Data Folder in the same directory .

 2.2 CC Data consolidation of modeling results

from Context Capture The model we built , Every Data The folder contains multiple “Tile_***” Folder . The new folder is named “Data”, Context Capture Data each “Data” In folder “Tile_***” Copy the folder to the new “Data” In the folder , And will xml File moved to and Data Folder in the same directory .

Be careful ： In use CC When modeling , When customizing the modeling boundary, you need to pay attention to the selection of boundary tiles , Avoid automatic segmentation by boundaries .

 3. Figure New Earth loading combined tilt model data

By mapping the new earth “ Import / export ” modular -> Import tilt photography （Context Capture）-> Select what needs to be loaded “Data” Folder , And select “ Common mode ”, Just import .

If it is the data of the engineering coordinate system , Please use precise mode

  Data loading results after data consolidation ：

  The figure below 0721 Merge .lfp A layer , And before 4 individual lfp The display effect of layers is exactly the same .

Be careful ： If the load is successful , But I can't see the data , It may be the terrain data display , Tilt data height problem , It can be done by “ edit ” modular -> Model editing （ Tilt model editing ）, Just go up high .
