@mytheshow 这个是需要修改serviceUrl
https://github.com/sakitam-fdd/wind-layer/blob/master/server/config/config.js#L4 的,默认对应关系如下:
- 间隔1度:https://nomads.ncep.noaa.gov/cgi-bin/filter_gfs_1p00.pl
- 间隔0.5度:https://nomads.ncep.noaa.gov/cgi-bin/filter_gfs_0p50.pl
- 间隔0.25度:https://nomads.ncep.noaa.gov/cgi-bin/filter_gfs_0p25.pl
但是数据量过大可能扛不住,建议可以使用不同层级对应不同粒子数量来解决这个问题

你好,我这里还是不行,我的代码:
当精度为0.25时对比图,我的风向全是一个方向;而 "真气网"精度0.25时,风向很清晰:

大佬,有时间能否帮忙看看这里,不知道你有没有遇到这个问题( ⊙ o ⊙ )?

@mytheshow 你使用的是哪个包哪个版本
from wind-layer.
当前最新的,直接clone下来的

@mytheshow 关于数据这块我不能提供太多信息,但是实际的格点数据处理也并不复杂,这个需要你自行研究。另外我看了一下真气网,他应该使用的是leaflet对应的插件,对应的你如果使用的ol地图类库的话可以查看此项目的0.1版本,但是这个版本实际有一些无法解决的问题,比如地图不可旋转、投影变换、粒子控制等。对于真气网的效果这个效果涉及业务处理,只提供一个思路:
- 监听地图视图分辨率变化事件
- 在事件中处理粒子数量的基值particleMultiplier
- 重绘

好的,现在我用leafletVelocity做了,非常感谢!
