我尝试了下面的
(我使用SELECT SUM(amount) as FirstQamount
FROM C_Payment_Service_Fee
WHERE MONTH(crn_dt) IN (1,2,3)
代表 ED50 ,也许这就是错误)
+proj=longlat +ellps=intl +no_defs
但结果不好proj4(new proj4.Proj('+proj=longlat +ellps=intl +no_defs'),
new proj4.Proj('+proj=longlat +ellps=WGS84 +datum=WGS84'),
[669257.722015602, 3556445.24116905]);
所需的结果是([79.34262031843741, 0])
。
