经纬度精度通常指的是地理坐标系统中,经度和纬度值的精确度。在不同的应用场景中,经纬度的精度要求可能会有所不同。以下是一些常见的精度级别: 1. **度(°)**: - 1度的精度可以定位到大约111公里的范围。 - 例如,只知道一个城市的经纬度到度的精度,可以确定城市大致的地理位置,但无法确定城市内的具体位置。 2. **分(')**: - 1分等于1/60度,大约等于1.85公里。 - 提供到分的精度可以进一步缩小定位范围,但仍然不够精确。 3. **秒(")**: - 1秒等于1/3600度,大约等于30.9米。 - 提供到秒的精度可以定位到一个较小的区域,例如一个街区或一个公园。 4. **小数点后几位**: - 经纬度通常可以表示为小数点后几位的十进制数。 - 小数点后第一位(十分位)表示0.1度,大约11.1公里。 - 小数点后第二位(百分位)表示0.01度,大约1.11公里。 - 小数点后第三位(千分位)表示0.001度,大约111米。 - 小数点后第四位(万分位)表示0.0001度,大约11.1米。 - 小数点后第五位(十万分位)表示0.00001度,大约1.11米。 5. **米级精度**: - 一些现代GPS设备和智能手机可以提供米级精度,这通常足够用于大多数导航和定位服务。 6. **厘米级精度**: - 高精度的应用,如土地测绘、建筑施工等,可能需要厘米级的精度。 在实际应用中,经纬度的精度取决于多种因素,包括GPS设备的精度、信号条件、环境因素等。例如,城市中的高楼大厦可能会影响GPS信号,导致定位精度下降。不同的应用场景,如地图服务、导航、地理信息系统(GIS)等,会根据需要选择合适的精度级别。 https://api.open-meteo.com/v1/forecast?latitude=34.125,34.125,34,34,33.875,33.85,33.75,33.9,33.6,33.625,33.5,33.51,33.375,33.375,33.25,33.25,33.15,33.125&longitude=106.8,107.125,106.875,107.18,106.92,107.125,106.875,107.15,106.9,107.125,106.875,107.125,106.91,107.125,106.875,107.13,106.875,107.125&hourly=precipitation_probability,precipitation&timezone=Asia%2FSingapore https://api.open-meteo.com/v1/forecast?latitude=34.125,34.125,34,34,33.85,33.875,33.9,33.75,33.625,33.6,33.51,33.5,33.375,33.375,33.25,33.25,33.125,33.15&longitude=107.125,106.8,107.18,106.875,107.125,106.92,107.15,106.875,107.125,106.9,107.125,106.875,107.125,106.91,107.13,106.875,107.125,106.875&hourly=temperature_2m,relative_humidity_2m,precipitation_probability,precipitation&timezone=Asia%2FSingapore ``` json [{"id":1,"name":"倒回沟","lat":34.125,"lon":106.8,"targetLat":34.125,"targetLon":106.875,"elevation":1782}, {"id":2,"name":"柳沟","lat":34.125,"lon":107.125,"targetLat":34.125,"targetLon":107.125,"elevation":2063}, {"id":3,"name":"黄家沟","lat":34,"lon":106.875,"targetLat":34,"targetLon":106.875,"elevation":1612}, {"id":4,"name":"源头山","lat":34,"lon":107.18,"targetLat":34,"targetLon":107.125,"elevation":1693}, {"id":5,"name":"大竹塘沟","lat":33.875,"lon":106.92,"targetLat":33.875,"targetLon":106.875,"elevation":1562}, {"id":6,"name":"艾蒿沟","lat":33.85,"lon":107.125,"targetLat":33.875,"targetLon":107.125,"elevation":1642}, {"id":7,"name":"南沟口","lat":33.75,"lon":106.875,"targetLat":33.75,"targetLon":106.875,"elevation":1433}, {"id":8,"name":"李家坎","lat":33.9,"lon":107.15,"targetLat":33.75,"targetLon":107.125,"elevation":1490}, {"id":9,"name":"楼房沟","lat":33.6,"lon":106.9,"targetLat":33.625,"targetLon":106.875,"elevation":1372}, {"id":10,"name":"东沟","lat":33.625,"lon":107.125,"targetLat":33.625,"targetLon":107.125,"elevation":1942}, {"id":11,"name":"九条沟","lat":33.5,"lon":106.875,"targetLat":33.5,"targetLon":106.875,"elevation":1230}, {"id":12,"name":"杀牛坪","lat":33.51,"lon":107.125,"targetLat":33.5,"targetLon":107.125,"elevation":1127}, {"id":13,"name":"云雾山","lat":33.375,"lon":106.91,"targetLat":33.375,"targetLon":106.875,"elevation":1545}, {"id":14,"name":"三岔河","lat":33.375,"lon":107.125,"targetLat":33.375,"targetLon":107.125,"elevation":924}, {"id":15,"name":"沙河沟","lat":33.25,"lon":106.875,"targetLat":33.25,"targetLon":106.875,"elevation":799}, {"id":16,"name":"天台山","lat":33.25,"lon":107.13,"targetLat":33.25,"targetLon":107.125,"elevation":758}, {"id":17,"name":"五道沟","lat":33.15,"lon":106.875,"targetLat":33.125,"targetLon":106.875,"elevation":524}, {"id":18,"name":"徐望","lat":33.125,"lon":107.125,"targetLat":33.125,"targetLon":107.125,"elevation":520}] ``` ``` sql SELECT parse_uuidv7_time('0193843c-dec3-771f-a38a-5abfb78c9ca6'); (node:2098075) [DEP0040] DeprecationWarning: The `punycode` module is deprecated.
