2018年2月22日 · We are working implementing a GPS validation system, and I told him the longitude -180 (or 180W) is not a valid longitude because a valid longitude is the same value as one of the angular values of the spherical coordinates, and the latitude is the another one. In spherical coordinates: Theta must be (-180,180].

2018年11月20日 · The - 180 part shifts it back to the range of [-180,180). Here's another one-liner, one that doesn't rely on 36,000 being big enough: longitude = (longitude % 360 + 360 + 180) % 360 - 180 The longitude % 360 + 360 part will ensure the value stays in the positive domain when it's later modded by 360.

2016年7月12日 · I have a netCDF file that contains climate data in a Gaussian grid. The longitudes are given from 0 to 360. I need to convert this to -180 to 180. Is this the correct formula - If longitude is greater than 180 subtract 360. I am looking to do this in Fortran.

Then use a clip process to split the polygons at the 180,-180 line and shift any parts which lie outside the -180,180 space by adding or subtracting 360° as appropriate. Just get it all done before you save it with a particular projection/datum

2019年9月15日 · Generic 2D polygon intersection does not work in this case if you simply use latitude for y and longitude for x, because the flat coordinate system will have edges at -180 and 180 longitude, and -90 and 90 latitude. Antarctica will go off the page on three of the edges.

2017年9月22日 · Although these solutions might have worked for some, in my case, I needed to do rendering transformations of .grib2 rasters on the fly. Geoserver WMS reprojection worked well for the raster itself but the created contours and wind arrows were created only for 0 - 360 longitude and not for -180,0.

2020年8月11日 · Any decent world map will likely have latitude and longitude markings, there's a reference. There are occasions when working over the international date line a 0-360 system is used but most common 0 longitude is around Greenwich and ranges -180 to 180. Latitude systems don't vary AFAIK, they're -90 to 90.

2017年1月4日 · // southwest, northeast final LatLngBounds world = new LatLngBounds( new LatLng(-90, -180), new LatLng(90, 180)); assertTrue(world.contains(new LatLng(0, 0))); // test fails So obviously, normalizing longitude to [-180, 180) has a cost in terms of how LatLngBounds works. We can only speculate as to why the API designers might have made this ...

2019年1月25日 · Although it looks bad, and we know that the -179 longitude is close to the 179, for that coordinate system that is not true. In the polygons that you have in the background, the polygon of Antarctica has points defined in longitude 180; Russia has, in its multipolygon feature, a continental part defined for positive lengths and another part for ...

2020年5月28日 · there should be an EPSG value, and that is your coordinate system. according to this right here what you need to do about your over 180 degrees coordinate value is to subtract/add it by 360 until it is in the range of -180 and 180 degrees. to verify if your data is correct, you might want another shapefile, that you know that the shapefile is ...
