1.3. 切片規則
經緯度坐標一般默認(x0,y0)=（-400,400）作為切圖的起始點，即從這開始算行列號。假設切圖的地圖某點坐標為x，y,切圖的瓦片大小為256，其瓦片的級別分辨率為resolution，則計算該地圖點的行列號計算如下：
col = | floor((x0 - x)/(256*resolution)) |;
row = | floor((y0 - y)/(256*resolution)) |;
LOGInfos是每個層級切片信息，ID是層級，Scale是比例尺大小，Resolution是當前比例尺層級下切片的每個像素點代表的實際長度；
0級 Resolution = 20037508.3427892 * 2 / 256 = 156543.03392804062
1級 Resolution = 20037508.3427892 * 2 / 256 / 2 = 78271.51696402031
n級 Resolution = 20037508.3427892 * 2 / 256 / 2 ^ n = ****
……………….
col = | floor((x0 - x)/(256*resolution)) = floor((-20037508.3427892-(-20037508.3427892)/(256 * 156543.03392804062)) | = 0
row = | floor((y0 - y)/(256*resolution)) = flow((20037508.3430388-20037508.3430388)/(256 * 156543.03392804062)) | = 0
col = | floor((x0 - x)/(256*resolution)) = floor((-20037508.3427892-12388034.5186361)/(256 * 156543.03392804062)) | = 0
row = | floor((y0 - y)/(256*resolution)) = flow((20037508.3430388-3594413.03659627)/(256 * 156543.03392804062)) | = 0
col = | floor((x0 - x)/(256*resolution)) = floor((-20037508.3427892-12388034.5186361)/(256 * 0.597164283477939)) | = 212106 = 33C8A（轉16進制）
row = | floor((y0 - y)/(256*resolution)) = flow((20037508.3430388-3594413.03659627)/(256 * 0.597164283477939)) | = 107559 = 1A427（轉16進制）
