Sql STContains、STIntersections和STWithin返回错误的地理结果

我正在使用SQL服务器存储客户的位置信息(经度和纬度)，并使用宣传单在 map 上显示它们.我还使用了LEAFLE绘制多边形来绘制城市区域，我将多边形存储在另一个带有地理类型的SQL表中，最后通过使用下面的查询，我想知道客户是否在一个区域(多边形)内:

DECLARE @latitude DECIMAL(25,18);
DECLARE @longitude DECIMAL(25,18);
DECLARE @customerId BIGINT;
DECLARE @geographicalAreaId INT;
DECLARE @coordinates GEOGRAPHY;

DECLARE @isInsideArea BIT;

declare @insideCOUNT int;
SET @insideCOUNT=0;

DECLARE @point geography;
DECLARE @polygon geography;

DECLARE getCustomerGeo_CSR CURSOR FAST_FORWARD READ_ONLY 
FOR

    SELECT DISTINCT Fk_CustomerId,ca.Latitude,ca.Longitude FROM Tbl_CustomerAddresses ca
        WHERE ca.Latitude IS NOT NULL AND ca.Longitude IS NOT NULL;

OPEN getCustomerGeo_CSR; 
FETCH NEXT
FROM getCustomerGeo_CSR
INTO @customerId,@latitude, @longitude

WHILE @@FETCH_STATUS = 0
BEGIN

SET @point = geography::Point(cast(@latitude as float), cast(@longitude as float), 4326);

    DECLARE getGeoArea_CSR CURSOR FAST_FORWARD READ_ONLY 
    FOR
        SELECT ga.GeographicalAreaId,ga.Coordinates               
        FROM   Tbl_GeographicalAreas ga         
    
    OPEN getGeoArea_CSR; 
    FETCH NEXT
    FROM getGeoArea_CSR
    INTO @geographicalAreaId, @coordinates

    WHILE @@FETCH_STATUS = 0
    BEGIN
        
        SET @polygon = geography::STGeomFromText((SELECT Coordinates FROM Tbl_GeographicalAreas WHERE GeographicalAreaId = @geographicalAreaId).STAsText(),4326);


        IF @polygon.STContains(@point) = 1
        BEGIN
            SET @insideCOUNT = @insideCOUNT+1;
        END
        
         FETCH NEXT
         FROM getGeoArea_CSR
         INTO @geographicalAreaId, @coordinates
    END
    CLOSE getGeoArea_CSR;
    DEALLOCATE getGeoArea_CSR;
    

    FETCH NEXT
    FROM getCustomerGeo_CSR
    INTO @customerId,@latitude, @longitude
END
CLOSE getCustomerGeo_CSR;
DEALLOCATE getCustomerGeo_CSR;

print @insideCOUNT;

但我总是得到错误的价值……

这是我的一个多边形:
