The information matching unit 230 may compare the acquisition time of the digital or analog data with the geographic identification metadata, and match the digital or analog data and the geographic identification metadata having the same acquisition time according to the comparison result.

In this case, the geographical identification metadata may include not only location information but also its acquisition time.

The pattern extractor 240 may extract a dynamic pattern for the position of the matched digital or analog data. Here, the dynamic pattern may be classified into any one of a stationary state, a moving state, and a stationary state.

As shown in FIG. 4, the geotagging server according to the present invention may collect digital or analog data obtained from a communication device and geographic identification metadata of the communication device (S410).

In this case, the geotagging server 1) to collect digital or analog data and geo-identification metadata generated by the communication device itself, or 2) to obtain digital or analog data and location information of the communication device generated by the communication device itself. 3) a separate device for acquiring the location information of the digital or analog data and the communication device generated from a separate device for generating digital or analog data generated from the geographic identification metadata generated from the device of The geographic identification metadata generated from may be collected through communication equipment.

5 is an exemplary view showing the content of collected data according to an embodiment of the present invention.

As shown in FIG. 5, the figure (a) shows the digital or analog data, and shows the digital or analog data acquired according to the time t (t1 to tn). Here, the digital or analog data includes acquisition time information.

And (b) shows the geo-identification metadata indicating the location information of the communication equipment, showing the location information obtained according to the time T (T1 ~ Tm). Here, the geographic identification metadata includes acquisition time information and location information.

Next, the geotagging server may match the digital or analog data with the geo-identification metadata by comparing the obtained time information (S420). That is, the time information of the geographic identification metadata is compared using a time at which digital or analog data starts to be generated (hereinafter referred to as a start time) and an end time (hereinafter referred to as an end time).

Specifically, it is as follows. First, when the start time of the digital or analog data is t1 and the end time is t10, the geotagging server uses the time information of the digital or analog data to binary search the time information of the geo-identification metadata. Here, the binary search is not compared sequentially at the beginning or end of the time list to be searched in the continuous list T1 to Tm of the sorted geographic identification metadata, but the item located in the center is compared with the item to be searched. According to the result, one of the following three operations is performed.

1) If the start time t1 of the digital or analog data to be searched is smaller than the comparison object and there is more data to be searched, the binary search can be continued for the half of the list remaining on the smaller side of the comparison object.

2) If the start time t1 of the digital or analog data to be searched is equal to the comparison target, the search can be stopped because the comparison target is the value to be searched.

3) If the start time t1 of the digital or analog data to be searched is larger than the comparison object and there is more data to be searched, the binary search can be continued for the half of the list remaining on the larger side of the comparison object.

As such, binary search continues to compare the time information of the middle item among the half lists containing the time information until the start time t1 of the digital or analog data is searched or the remaining list to be searched becomes very small. do.

When the binary search is performed, the time information of the geographic identification metadata matching the start time t1 of the digital or analog data is searched, and then the binary search is performed again for the end time t10 of the digital or analog data.

6 is an exemplary view showing a binary searched and matched content according to an embodiment of the present invention.

As shown in Fig. 6, the start time t1 of the binary searched digital or analog data matches the time information T3 of the geo-identification metadata, and the end time t10 of the digital or analog data matches the time information T12 of the geo-identification metadata. If so, it is finally binary searched to show the match.

Therefore, based on the matched contents of the start time t1 and the end time t10 of the digital or analog data, the continuous lists t1 to t10 of the digital or analog data may be matched to the continuous lists T3 to T12 of the geographical identification metadata, respectively.

Next, the geotagging server may extract the dynamic pattern for the position of the digital or analog data using the matched digital or analog data and the geo-identification metadata (S430).

Specifically, it is as follows. First, the geotagging server can select any sample for the matched digital or analog data and the geo-identification metadata. This arbitrary sample can be selected using a random number function or a random function.

The geotagging server may select a buffer space of a specific radius according to the type of communication equipment based on the location including the geo-identification metadata selected by an arbitrary sample. Here, the buffer space uses information managed by the storage medium of the communication device or system, and the number of samples uses a preset value within the range of the total number.

7 is an exemplary view showing the data content of a selected sample according to an embodiment of the present invention.

As shown in Fig. 7, the selected geographic identification metadata is shown as an arbitrary sample, and includes time information, location information, and a buffer radius of the geographic identification metadata.

By comparing the location information between each selected sample, the dynamic pattern for the digital or analog data is classified into the stationary state, the moving state, and the stationary state. The classification method is as follows.

1) In the stopped state, each selected sample includes the same position information within a certain error range. Here, the error range may be set in the communication equipment or the service server.

For example, within a certain error range, the samples may have a relationship such as A3 = A4 = A6 = A8 = A9 = A10 = A12.

2) In the shifted state, all of the selected samples do not contain the same positional information within a certain margin of error, but include buffer space of other specimens in adjacent time zones within the radius of the positional information including the buffer space of each specimen. The radius of the location information does not cross each other (notation: <>).

For example, within a certain error range, the samples are A3 ≠ A4 ≠ A6 ≠ A8 ≠ A9 ≠ A10 ≠ A12 and (A3 + r) <> (A4 + r) <> (A6 + r) <> (A8 + r) < A relationship such as> (A9 + r) <> (A10 + r) <> (A12 + r) may be established.

3) In the stationary state, within the radius of the location information including the buffer space of each selected sample, the radius of the location information including the buffer space of another sample in an adjacent time zone intersects each other and includes the buffer space of each selected sample. Within the radius of the location information, the radius of the location information, including the buffer space of any other sample, intersects each other.

For example, (A3 + r) <> (A4 + r) <> (A6 + r), (A6 + r) <> (A8 + r), (A8 + r) <> (A9 + r) <> ( A10 + r) and (A1 + r) <> (A12 + r), (A3 + r) <> (A9 + r), (A4 + r) <> (A10 + r), (A6 + r) < > (A12 + r), etc. can be established.

In addition, the dosing state is also covered in the indoor or underground, the location information is lost because it is unknown.

Next, the geotagging server may tag the geo-identification metadata preset to the digital or analog data according to the extracted dynamic pattern (S440). That is, the geotagging server may generate geotagging data including preset geo-identification metadata according to the extracted dynamic pattern and tag the generated geotagging data on digital or analog data.

8 is an exemplary view showing the content of geotagging data according to an embodiment of the present invention.

As shown in FIG. 8, the geotagging data in FIG. (A) may include start time, end time, dynamic pattern, location link information, and the like of digital or analog data.

The position link information is changed according to the dynamic pattern. If the dynamic pattern is in the stopped state, the position information [A3] which is stopped may be set in the position link information.

The position link information is set by the position information A3 to A12 where the dynamic pattern is moving as shown in Fig. (B). For example, [A3, A4, A5, A6, A7, A8, A9, A10, A11, A12] is set in turn. Can be.

The location link information is the location information where the dynamic pattern is settled as shown in Figs. (C) and (d). The boundary area information is the location information at the top left and the bottom right. The connected rectangular block blcok or outermost line may be indicated.

For example, the position link information includes [(x value of A3, y value of A12), (x value of A6, y value of A8)] or [(x value of A3, y value), (x value of A4, y Value), (x value of A5, y value), (x value of A6, y value), (x value of A7, y value), (x value of A12, y value), (x value of A11, y Value), (x value of A10, y value)], and the like.

Next, the geotagging server may output digital or analog data tagged with geo-identification metadata. In addition, the geotagging server may output the digital or analog data tagged with the geo-identification metadata in combination with the spatial information or the non-coordinate-based geo-identifier (S450). Here, the spatial information may represent a geospatial image, a rider, a digital map, and an cadastral map. The non-coordinate-based geographic identifier may represent administrative district information such as address, distance, and intellectual information such as land location, land number, land category, boundary, and the like.

This is to handle the connection with various types of business processes.
