Server 20 is according to the screen resolution and the networking mode of client 10, and inquiry terminal ability base 203 draws corresponding ability ID number; Utilize this ability ID query strategy application rule storehouse 205 then, obtain corresponding transmission policy ID; Utilize this strategy ID can know the focus city quantity that at every turn sends this client 10 to and whether carry corresponding information list.In this example, suppose the national focus of client 10 inquiry city, and ability parameter is ({ 320x240}, { GPRS}).Then server 20 will be according to table one, table

Two, table three is determined to return to the focus city number of client 10 to be 5 (is the related data in 5 the highest cities of domestic information temperature, and the information of subsidiary city correspondence.

City list and temperature value thereof that client passes over according to server, the city correspondence position is drawn the information thermodynamic chart of different colours and size on screen map.

The mode of the drafting of described city thermal figure is: by calculating each color of pixel value on the screen, draw this point according to this color value on screen again and realize that the calculating of its color value is according to the temperature in focus city and position calculation;

c _i=f (H, G, x _i, y _i) formula 5

Wherein, c _iBe the color value that i is ordered, H is a focus city temperature value set, and G is the set of focus civic location information, (x _i, y _i) be the coordinate of i point in screen.

Step 306: the focus city in the territorial scope that service end 20 inquiring client terminals 10 are asked.

The geographic range that server 20 is asked according to client 10 (Lo1, La1), (Lo2 La2), utilizes the focus city number m of the transmission policy Px defined that geographical information library 208 and integrating step 305 determine, obtains the focus city data that need return:

{city1，Lo1，La1，

city2，Lo2，La2，

...

citym，Lom，Lam

}

Step 307: the heatrate in service end 20 inquiry focus cities.

Server 20 utilizes the pairing heatrate value in focus city that obtains in 206 query steps 306 of temperature storehouse, city, i.e. { h1, h2, h3, h4, h5}.

Step 308: server 20 returns focus city data to client.

If the tactful Px that step 305 is determined does not require subsidiary specifying information, then server 20 returns the data that step 306 and step 307 obtain to client 10, and the form of server 20 return datas is:

{city1，Lo1，La1，h1

city2，Lo2，La2，h2

...

citym，Lom，Lam，hm

}

Forward step 311 then to;

If Px requires to carry data, then forward step 309 to.

Step 309: server 20 inquiry focus urban informations.

The information of relevant focus city (being determined by step 306) in the server 20 Query Information storehouses 207, the bar number of information is by the determined transmission policy Px decision of step 305, promptly

{info1.1，info1.2，..info1.x

...

infom.1，infom.2，...，infom.x

}

Wherein x is the bar number of the information of at every turn carrying of Px definition.

Step 310: server 20 returns focus city data and relevant information thereof to client 10

The data that server 20 obtains step 306, step 307, step 309 are returned client 10, and its form is:

{city1，Lo1，La1，hlinfo1.1，...，info1.x

city2，Lo2，La2，h2，info2.1，...，info2.x

...

citym，Lom，Lam，hm，infom.1，...，infom.x

}

Step 311: client 10 is drawn city thermal figure according to the focus city data that server 20 returns.

Client 10 is at first calculated each color of pixel value on the screen according to the position and the temperature in each focus city.Use the another kind of concrete form of formula 5 in this example:

$c_i(r,g,b,\mathrm{\α})=f(H_1^N,G_1^N,x_i,y_i)$

r＝h _i×2+55

G=0 formula 6

b＝0

α＝h _i/100

$h_i=\mathrm{int}\left({\max }_{j=1}^N(H_j-\sqrt{{(G_{\mathrm{jx}}^{\′}-x_i)}^2+{(G_{\mathrm{jy}}^{\′}-y_i)}^2}\×K)\right)$

Wherein: (r, b g) are the rgb value of screen point, and a is the alpha value (transparency of this value representation when screen point is drawn, 1 for opaque fully, 0 for transparent fully) of screen point, and int () is a bracket function, and K is that an expression is along with constant and assurance
