3.1) obtain the city list that need to show;
3.2) obtain next urban information;
3.3) obtain the weather condition in current city;
3.4) obtain the expression this weather figure coordinate;
3.5) draw the coordinate points in this city at map;
3.6) draw and show the simple frame of this urban weather information of expression.
Implementation of the present invention is specifically referring to Fig. 2-Tu, and 6, at first draw round the clock information at map.Here ignored the revolution impact of the earth, only consider the rotation factor, assert and be round the clock 12 hours, calculate the area of current 0:00 according to main frame time and main frame time zone meter, then with this area as the most black part, respectively draw to the left and right the gradual change black in 6 time zones, then continue to draw from the screen another side such as screen border, represent to concern round the clock with this, the transparent print layer of simply drawing the somber of one deck gradual change hides world map, to represent round the clock conversion.
Then, calculate the coordinate points of selecting the city according to the urban information of user selection and the transformational relation of screen pixels, here need to prove because the restriction of embedded device screen size, may overlap at map owing to the factor of engineer's scale for the city of closing on the map, here need to do according to the mode of nine grids according to the latitude and longitude information in city the skew of certain direction, if two city longitudes and latitudes are identical, then acquiescence is toward upper right skew, referring to Fig. 2.
Obtain at last the concrete Weather information in this city by API, concrete weather representation according to prior agreement, give a kind of graphical information of concrete weather to coordinate points, as shown in table 1, be presented on the world map of the current expansion of screen, and the rendering text frame represents concrete Weather information around point, equally, demonstration according to embedded device, the text box here has the up and down manifestation mode of superposition, to the text box of the weather details pressure that change, text frame has the operation of choosing the automatic integral top set according to the sequencing that calculates, and the while also can be launched zoom operations by the click of city coordinate points.
Table 1
This method to the integration of obtaining data, has the technique of expression that 3 large key steps are finished world weather, referring to Fig. 3 by the analysis to cartographic information; At first, draw at map according to the main frame time and to represent the round the clock time dense fog of information, then obtain the coordinate information in current selected city, obtain at last the Weather information in selected city by API, according to the coordinate information that obtains, show coordinate points and the weather concise message of the current urban weather of expression.
Referring to Fig. 4, at first obtain the current time of main frame, according to the time-zone information of main frame, the time zone when calculating 0:00 obtains x coordinate corresponding to screen.Then, to 5 time zones in 0 time zone left side, namely the time dense fog of gradual change is added in the 19:00-00:00 zone, if left field show not, then continue left to show from the screen low order end.Then, to 6 zones on the right side in this 0 time zone, namely similar time dense fog, the drawing process of deadline dense fog are added in the 0:00-6:00 zone.
Owing to considering that there is error in the map on reduced scale, if simple calculating according to longitude and latitude may cause the location inaccurate, if for each storing coordinate position, city is again a thing that wastes time and energy very much, adopted the method for dwindling orientation range to reduce this error here.At first obtain the latitude and longitude information of target cities, then from database, search the physical location of capital on the map that dwindles of current city the country one belongs to, calculate this target cities with respect to the skew of capital city according to engineer's scale, orient the actual coordinate value in this city.At last, judge whether this coordinate figure follows other city coordinate of queue stores that conflict is arranged, if conflict is arranged, then carry out the realization coordinate offset that the nine grids shifting algorithm is finished target cities, repeat above-mentioned steps until calculate the city coordinate information of storing in all formations.
Referring to Fig. 6, at first obtain the real-time Weather information in current city by API, then search the corresponding table of weather coordinate points (table 1) according to different state of weather and obtain current city map coordinate points, show corresponding map reference point and the simple frame that shows around this urban weather detail at map, if need superposition, then rear one covers previous processing.Until shown the city that all are selected.
Specific embodiments of the invention are referring to Fig. 7 .1-Fig. 7 .4, Fig. 7 .1 is the time dense fog state representation of peacetime state, wherein the details in 2 cities has been carried out shrink process: Fig. 7 .2, Fig. 7 .3 show (non-time dense fog state) for the world map of part weather: Fig. 7 .4 is the processing mode that Weather information overlaps.
