Addressing figure spot layer is as planar graphical element, and its net area=addressing figure marble area-addressing zero object plane is long-pending-and addressing line object plane is long-pending-raised path through fields area;

Wherein, addressing figure marble area is the geometric area of its figure, raised path through fields area=(addressing figure marble area-addressing zero object plane long-pending-addressing line object plane is long-pending) * raised path through fields coefficient;

In data pre-service to addressing figure spot layer, the topology that relates to multi-layer image is related, and as step I) the stacked result's of operation addressing zero thing layer, addressing line thing layer, addressing figure spot layer etc. has been inherited the fragmentary atural object in the present status of land utilization database, linear ground object, pass through a left side between the data Layers such as ground class figure spot, right figure spot is encoded and is identified its this topological relation each other, a certain graphical element for addressing figure spot layer, the utilization spacial analytical method, utilize the left side in the multi-layer image respectively, the addressing zero thing layer that right figure spot code identification comes cyclic search and its overlapping to arrive, graphical element in the addressing line thing layer, and it is long-pending long-pending with addressing line object plane to write down its corresponding addressing zero object plane, when loop ends, upgrade its corresponding area value according to the computing formula of addressing figure spot net area.

5. a kind of construction project according to claim 1 is intended the method that addressing is extracted automatically, it is characterized in that described construction project plan addressing to appointment, carry out area statistics according to land use classes, and the output construction project is intended the result step that addressing is extracted automatically:

K) the ground class index that construction project is intended in the addressing red line scope is carried out according to three major types classification carrying out merger, that is: farming land, construction land and unused land, wherein the farming land index is wanted the refinement secondary ground class adjustably class corresponding with it, and merger result in view of the above, to intend addressing red line block is unit, and the land classification area of intending in the addressing red line scope is added up;

L) according to actual needs, the statistics square measure is converted;

M) the output construction project is intended the result of addressing.
