In step 102, extract the track address in the road detected and extract the finger target value in the road detected.
The track address in road can Shi Gai road track data storage position, i.e. obtain the path of the track data in this road.Such as, the storage position of the file at the track data place that the track address in road can include and the track data in road position in this document.
Index can be used to describe the various indexs of the attribute of road geological data, such as, can be the abscissa of shot point, the vertical coordinate of shot point, the abscissa of geophone station, the vertical coordinate of geophone station, CMP (CMP, CommonMiddlePonit) number, the vertical coordinate of the abscissa of CMP, CMP, static correction value, offset distance etc..It should be understood that be not limited to index enumerated above.
In one example, the N kind extracting the road detected refers to target value, and N is the natural number more than 0.N kind index can be preset by user, it is also possible to is defaulted as conventional index.
In step 103, the track address with the identical road referring to target value among the road detected is divided into a subset.Specifically, divide according to the track address referring to the target value road to detecting in the road detected, the track address with the identical road referring to target value is divided into a subset, to form at least one subset.It should be understood that for a kind of index, the quantity of the subset of formation depends on the quantity of the different value of this index.
In a preferred embodiment, utilize the method shown in Fig. 2 that the track address with the identical road referring to target value among the road detected is divided into a subset.
In step 104, in the way of mapping, the index of each subset, the finger target value of each subset and each subset are stored in index file.Specifically, by the index of each subset, each subset refer to that target value and storage corresponding to each subset are in index file, so, the index of a subset and refer to that target value is equivalent to the label of this subset.
In step 105, receive the scope referring to target value of user's input.Specifically, the M kind receiving user's input refers to the scope of target value, i.e. receiving every kind of scope referring to target value in the M kind index of user's input, wherein, M is the natural number more than 0 less than or equal to N.It should be understood that user inputs M kind refers to the scope of target value, i.e. user wants to obtain M kind in seismic data acquisition and refers to target value road geological data in the scope of input.
In step 106, the subset corresponding to target value of the finger in detection range from index file.Can first from index file detection and described M kind index there is the subset of mapping relations, i.e. detection subset corresponding to M kind index from index file, in other words, from index file, detect the subset only with M kind index.Then referring to that target value all meets the M kind of user's input and refers to the subset of scope of target value from M kind described in the sub-centralized detecting of detection, wherein, M is the natural number more than 0 less than or equal to N.
