* @memberOf w-gis
* @param {Array} ops 輸入二維座標加觀測數據點陣列，為[{x:x1,y:y1,z:z1},{x:x2,y:y2,z:z2},...]點物件之陣列
* @param {Object} [opt={}] 輸入設定物件，預設{}
* @param {String} [opt.keyX='x'] 輸入點物件之x欄位字串，為座標，預設'x'
* @param {String} [opt.keyY='y'] 輸入點物件之y欄位字串，為座標，預設'y'
* @param {String} [opt.keyZ='z'] 輸入點物件之z欄位字串，為觀測值，預設'z'
* @param {String} [opt.modePick='min'] 輸入挑選方式字串，可選'min'、'max'，預設'min'
* @param {Number} [opt.dx=0.000979087] 輸入網格x向間距數字，預設0.000979087，基於WGS84經緯度之數據點，代表約100m
* @param {Number} [opt.dy=0.000906247] 輸入網格y向間距數字，預設0.000906247，基於WGS84經緯度之數據點，代表約100m
* @param {Number} [opt.dxAgr=opt.dx*2] 輸入先聚合時網格x向間距數字，預設opt.dx*2
* @param {Number} [opt.dyAgr=opt.dy*2] 輸入先聚合時網格y向間距數字，預設opt.dy*2
* @param {Function} [opt.funValid=(x,y)=>{return true}] 輸入確認點座標(x,y)是否有效函數，回傳布林值，可使用Promise回傳，預設(x,y)=>{return true}

* @param {Function} [opt.funAdjust=(x,y,z)=>{return z}] 輸入內插後值調整函數，用於修正不合理值或做後處理，回傳布林值，可使用Promise回傳，預設(x,y,z)=>{return z}
* @param {Number} [opt.scale=1] 輸入當funKriging使用interp2Kriging時，正規化範圍數值，因處理多邊形時有數值容許誤差，故須通過縮放值域來減少問題，預設1是正規化0至1之間，使用scaleXY則是正規化為0至scaleXY之間，預設1
