有时,纬度/经度以度/分/秒表示,并且需要 N、S、E 或 W 方向才有意义。十进制纬度和经度表示为正数或负数,并且不需要基本方向。因此,如果您使用十进制值,它们不会被描述为“北纬”或类似的内容。
正纬度位于赤道上方 (N),负纬度位于赤道下方 (S)。
正经度位于本初子午线以东,而负经度位于本初子午线(穿过英格兰某点的南北线)以西。
您给出的这些值描述了爱达荷州某处的一个点(赤道以北,本初子午线以西)。

请注意,如果将纬度值更改为负值(-44...),该点将“镜像”穿过赤道,最终到达太平洋的某个地方海洋。经度也同样适用 - 将其设置为正值,您的点就会镜像到本初子午线,最终到达中国的某个地方。
Sometimes lat/long are expressed in degrees/minutes/seconds, and require a N, S, E, or W direction to make sense. Decimal latitude and longitude is expressed as either a positive or negative number and doesn't require a cardinal direction. So if you're using decimal values for these, they aren't described as "latitude north" or anything like that.
Positive latitude is above the equator (N), and negative latitude is below the equator (S).
Positive longitude is east of the prime meridian, while negative longitude is west of the prime meridian (a north-south line that runs through a point in England).
Those values you give describe a point somewhere in Idaho (north of the equator and west of the prime meridian).

Notice if you change the latitude value to a negative (-44...), the point is "mirrored" across the equator, ending up somewhere in the Pacific Ocean. Same works with the longitude - make it positive, and your point is mirrored across the prime meridian, ending up somewhere in China.
