Description
Technical field
The present invention relates to planning industry technology fields, more particularly, to a kind of spatial data that will plan that industry uses
The method and apparatus being put in storage.
Background technique
The spatial data that planning industry uses is usually to be carried out by specified designing unit of local or regional planning agency to city
The performance data exported after planning and designing, this kind of performance data are mostly the graph data of CAD, due to CAD data do not have attribute value,
It is inconvenient to save, so all can be converted to the spatial data with attribute value by the advanced row data conversion of CAD data and enter inventory
Storage, while conducive to later access or rule can be repaired by the attribute value of data together in database purchase.
But having a kind of distinctive data type in CAD data is " small short-term data ", the generation of this reference book be due to
The feelings lack of standardization for causing some line numbers to be engaged according to appearance suspension, without closure or only with the line closed on during CAD mapping
Condition, but after the small short-term data of broken line are converted to the spatial data with attribute value, can not be put in storage, so needing to carry out small
The processing of short-term.But interpretation inspection is manually carried out if passed through, efficiency is greatly influenced, meanwhile, artificial interpretation is also to exist
Error, so automatic inspection processing can be carried out to the spatial data of this respect by being badly in need of a method.
Therefore it provides a kind of method and apparatus that will plan that the spatial data that industry uses is put in storage, before storage
It automaticly inspects the small short-term data wait be put in storage in spatial data and is handled, promote the efficiency of storage, be that solution is badly in need of in this field
Certainly the technical issues of.
