A2, increase its depth attribute field in the database for storing each floor level diagram data, while according to step 1
Each floor depth information of underground building thing of acquisition, the attribute calibration of its corresponding depth is carried out to corresponding floor plan；
Preferably, the visualization of the degree of underground building object depth described in step 3 sectional drawing is carried out according to the following steps：
B1, according to the calibrated database achievement of each floor depth of underground building thing in step 2, in underground building
When object depth degree sectional drawing visualizes, spatial dimension selected first, the relation of construction of structures and selected scope is shown under base area
Those underground building things in the range of, the relation includes underground building thing in selected scope, or underground building
Thing intersects with selected scope；
B2, some depth value or a depth bounds are set, by by the numerical value or number range and database
The depth attribute value of underground building object plane figure is matched, and obtains the floor set for meeting depth value condition；
B3, the plane coordinates information according to each building angle point in each planogram data of floor set, will be each with geometrical line
Angle point draws connection, forms the designated floor plan of the underground building thing of a certain depth bounds of closure.
The beneficial effects of the invention are as follows：For different depths when the present invention can browse underground building thing data according to user
The demand that degree underground building thing floor browses, realizes and carries out underground building thing floor plan by depth or depth intervals
Visualization, analytically descend spatial depth information, the planning management and application of the auxiliary relevant departments progress underground space.
