Explanation of Hypergraph on the Operation Process of Layered Monomer

Pattern 1: spatial query method using SQL.

data preparation

A. Building vector plane data: the attribute table contains the fields of bottom elevation and height (there are as many corresponding vector planes as there are floors in each building);

B tilt photography model: the configuration file generated by the tilt model that needs to be layered and divided. Scp in suppermap

Data superposition

1. Create a new file data source in the workspace and import the vector surface into the new data source;

2. Create a new spherical scene, right-click the normal layer in the Layer Manager of the spherical scene, select "Add 3D Slice Cache Layer", and select. Add the surface data imported from the new data source to the current spherical scene (the vector surface layer should be above the skew layer) in the scp file of the skew model generated before;

Layered monomer setting

1. Select the style setting in the menu (as shown).

Stretching Settings: Height Mode-Relative Height; Bottom elevation-the corresponding bottom elevation field in the attribute table; Stretch Height-The corresponding stretch height field in the attribute table;

Fill style: transparency100%;

2.? Right-click the vector surface layer added in the scene layer manager, select "Object Selection Style", change the foreground color to a color with high saturation, set the transparency to 50%, check "Paste Object" and confirm;

The final effect:

Method 2: Use shp data for spatial modeling and model stretching, and then rely on SmID for correlation and data query.

1. Data description:

House_4326 is converted from projection coordinates 4547 to latitude and longitude coordinates 4326 based on house data.

Config data is converted into s3m cache according to the tilt data given by you, and the center point is set as geographical coordinate system.

2.? Stretching modeling

When drawing modeling, select the bottom and drawing height, and select all objects to participate in the operation.

3.? Save the current scene after the modeling is completed.

4.? Right-click the scene to generate a scene cache and save it in the sibling directory of the workspace.

6.? Pay attention to the storage type and file type (original, s3m)

8.? When finished, close the workspace and publish the data to the designated iServer for testing.
