And is not particularly limited herein.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for displaying map information in accordance with the present application is shown. The method for displaying map information includes the steps of:
In this embodiment, an execution subject (e.g., the terminal devices 101, 102, 103 shown in fig. 1) of the method for displaying map information may receive feature data of at least one point of interest feature of a target point of interest transmitted by an electronic map server through a wired connection manner or a wireless connection manner.
In this embodiment, the execution main body may have an electronic map application installed therein, and the electronic map server is a server for providing support for the electronic map application installed in the execution main body.
In this embodiment, the target point of interest may be any one of a large number of points of interest supported by the electronic map server.
As an example, the target point of interest may be obtained by: first, a user inputs a geographic name keyword in an electronic map application, for example, the keyword "Yihe Garden"; then, the executive body sends the geographic name key words to an electronic map server; and then, the electronic map server inquires the POI corresponding to the geographic name key words, determines the found POI as a target interest point, acquires the characteristic data of at least one interest point characteristic of the target interest point and sends the acquired characteristic data to the execution main body.
As an example, the target interest point may also be obtained by: the user clicks a certain POI in the electronic map displayed by the electronic map application, and then the execution subject may determine the POI clicked by the user as the target point of interest.
In this embodiment, each interest point may include feature data of at least one interest point feature, where the feature data of each interest point feature may characterize some attribute feature of the interest point. For example, the point of interest features may include, but are not limited to, the following: name, subtitle, distance, address, price, prompt information, profile information, star information, tag information, heat information, access volume, parent-child relationship, parent-child attributes, user comments, picture information, headings, business hours, business status, data status, and the like.
It should be noted that the wireless connection means may include, but is not limited to, a 3G/4G connection, a WiFi connection, a bluetooth connection, a WiMAX connection, a Zigbee connection, a uwb (ultra wideband) connection, and other wireless connection means now known or developed in the future.
In this embodiment, in order to display the feature data of each feature of interest point of an interest point, the feature data of each feature of interest point of the interest point is displayed in the display area corresponding to each interest point. The display area corresponding to each interest point can be divided into a plurality of cells, and each cell can display the feature data of one interest point feature. Here, the shape of the unit cell is not particularly limited, and for example, the unit cell may be rectangular, triangular, diamond, trapezoidal, or the like.
In this embodiment, the execution subject may be preset with a correspondence between the point of interest feature and a cell in the point of interest display area, that is, given an interest point feature, a cell corresponding to the interest point feature may be found in the display area of the interest point. In this way, the execution subject may determine, in the display area of the target interest point, a cell corresponding to each of the at least one interest point feature according to the correspondence between the preset interest point feature and the cell in the interest point display area.
In step 202, cells corresponding to each of the at least one interest point feature have been determined in the display area of the target interest point, but if there are idle cells between the determined cells, displaying the feature data of the interest point feature directly according to the determined cells may result in a large display area occupied by the display area displaying the interest point feature, and the display effect is messy and not favorable for the user to view.
In order to reduce the area of the display area for displaying the interest point features, the execution subject may first align the determined cells in the display area of the target interest point according to a preset alignment rule. Here, the alignment rule is a rule that is preset to group a plurality of cells at different positions in the display area of the point of interest together so as to reduce idle cells between the aligned cells as much as possible, so that the display area occupied by each aligned cell is smaller than the display area occupied by each aligned cell.
In some optional implementations of this embodiment, the preset alignment rule may include upper left alignment, lower left alignment, upper right alignment, lower right alignment, or middle alignment.
Since each cell determined in the display region of the target interest point before the alignment corresponds to one of the at least one interest point feature, after the alignment, the aligned cell corresponding to each of the at least one interest point feature may be determined according to the correspondence between the cells before the alignment and the cells after the alignment.
And step 204, displaying the feature data of each interest point feature in the at least one interest point feature on the aligned cells corresponding to the interest point feature.
The execution subject may display the received feature data of each of the at least one interest point feature in the aligned cells corresponding to the interest point feature, because after the alignment operation in step 203, the display area occupied by each cell after alignment is reduced and the display style is more ordered compared to each cell determined before alignment.
In some optional implementations of this embodiment, the display area of each interest point may be divided into R rows, where R is a positive integer, and the heights of the rows in the R rows may be the same or different. The positive integer R may be set by various implementations. For example, R may be the maximum of the number of rows included in the historical point of interest presentation style. For another example, R may be set manually by a technician based on historical experience.
Alternatively, the positive integer R may be calculated by the following number of calculation steps. Specifically, referring to fig. 3, fig. 3 shows a flow 300A according to an embodiment of the present application for calculating the number of rows, where the number of rows calculating step 300A includes the following steps 301 to 303:
Here, the execution subject of the line number calculation step may be the same as or different from the execution subject described above. If the execution subject of the line number calculation step is different from the execution subject, the execution subject of the line number calculation step may send the determined positive integer R to the execution subject, so that the execution subject may divide the interest point display area into R lines when displaying the interest point feature.
Here, the execution subject of the line number calculation step may first acquire N historical interest point presentation patterns, where N is a positive integer. Each historical interest point presentation style may include style information that historically displays various interest point features in the interest point display area, and specifically may include the following:
(1) the nth historical interest point display pattern comprises RnA row, N being a positive integer between 1 and N;
(2) and the jth line of the nth historical interest point display style shows Fn(j) Individual point of interest characteristics;
(3) f aboven(j) The point of interest feature includes Pn(j) Kind of interest Point feature Categories, Fn(j) Greater than or equal to Pn(j) J is 1 to RnA positive integer in between. In practice, each point of interest feature may be associated in advance and only one type of point of interest feature category may be associated, and each type of point of interest feature category may include a plurality of point of interest features. As an example, the individual interest point features included in the interest point feature category are shown in table 1:
TABLE 1
in the substep 3021, the interest point feature categories included in the kth row in each historical interest point presentation pattern of the N historical interest point presentation patterns are merged, and repeated interest point feature categories in the history interest point presentation patterns are removed to obtain a kth row of interest point feature category set.
That is, the interest point feature category set in the k-th row includes various interest point feature categories associated with respective interest point features that have appeared in the k-th row of each historical interest point representation pattern in the N historical interest point representation patterns.
And a substep 3022 of determining a ratio of the first number divided by the second number as the rate of change roc (k) of the k-th row.
Here, the first number is the number of interest point feature categories in the k-th row of interest point feature category set, and the second number is Max (P)1(k),P2(k),…,PN(k))。
That is, the variation rate of the k-th line represents a ratio of the number of all the interest point feature categories included in the k-th line of the N historical interest point presentation patterns to the maximum value of the interest point feature categories included in the k-th line of each historical interest point presentation pattern in the N historical interest point presentation patterns, that is, represents a variation frequency of the k-th line in history.
Here, it can be understood that, if the variation rate roc (k) of the k-th row is historically larger, which indicates that more rows need to be expanded on the k-th row to meet the future display requirement on the k-th row, therefore, various implementation manners may be adopted to determine the expanded row number fr (k) corresponding to the k-th row according to the variation rate roc (k) of the k-th row, where the expanded row number fr (k) is positively correlated with the variation rate roc (k). For example, the following may be followed: fr (k) is determined as the result of rounding up (aroc (k) + b), where a is a constant greater than 0 and b is a constant.
Optionally, sub-step 3023 may be performed as follows:
calculating the expanded line number FR (k) corresponding to the k line according to the following formula:
wherein:
roc (k) is the calculated rate of change of the k-th line.
Roc1Is a constant greater than 1 and less than 2.
Roc2Is a constant greater than 2 and less than 3.
Fr (k) is the number of expanded lines corresponding to the k-th line obtained by calculation.
Wherein, Roc1And Roc2May be a constant that is set in advance empirically by a skilled person. For example, Roc1Can be set to 1.2, Roc2May be set to 2.4. That is, if the variation rate of the kth row is less than or equal to 1.2, the number of expanded rows corresponding to the kth row is 1, that is, the kth row is not expanded; if the variation rate of the kth line is greater than 1.2 and less than or equal to 2.4, the number of the expanded lines corresponding to the kth line is 2, namely, the kth line is expanded into 1 line to 2 lines; if the variation rate of the kth line is greater than 2.4, the number of expanded lines corresponding to the kth line is 3, that is, the kth line is expanded by 2 to 3 again.
Via sub-step 3023, already for 1 to Max (R)1,R2,…,RN) Each positive integer k in between, the number of expanded rows corresponding to each row is calculated, then 1 to Max (R)1,R2,…,RN) Each positive integer k in between corresponds toOf the expanded number of rows FR (k), i.e. of
The total number of lines included in the expanded interest point presentation style is the value of R.
The number of lines included in the interest point feature display region is already determined through sub-step 3024, that is, the number of lines included in the expanded interest point feature display region is obtained through statistical analysis of the historical interest point presentation pattern and expansion of the number of lines included in the historical interest point presentation pattern.
In practice, in addition to the need for despreading over a row, sometimes over a column. That is, it is also necessary to determine the number of columns included in each of the R rows included in the interest point display area, that is, the ith row of the interest point display area may be divided into CiColumn, i is a positive integer between 1 and R, CiIs the value of the ith dimension component of the vector C, CiIs a positive integer. Here, the vector C may be obtained in various implementations. For example, the vector C may be the maximum of the number of rows included in the historical point of interest rendering pattern.
