LineString() Points with wgs84 coordinates instead of X, Y ? about fields2cover HOT 6 CLOSED

If your reference point for the GPS is '(A, B)', and your UTM zone is 32N, then:

gps_ref = f2c.Point(A, B)
ref_xy = f2c.Transform.transform(gps_ref, "EPSG:4326", "UTM:32N datum:WGS84")
dubins_path.moveTo(ref_xy)
gps_path = f2c.Transform.transform(dubins_path, "UTM:32N datum:WGS84", "EPSG:4326")

@Gonzalo-Mier Thanks for your reply.
I got this error :

"ref_xy = f2c.Transform.transform(gps_ref, "EPSG:4326", "UTM:32N datum:WGS84")
TypeError: transform() takes 2 positional arguments but 3 were given"

I'm not sure, but also i think that the 1st argument of "Transform.transform" should be F2CField type (in my case i don't have a field).

Other question : As you see, every time i add a start.point and end.point to the path[i] to make a Line (example path0.addPoint( 5.0, -30.0), path0.addPoint( 0.0, 10.0))
Because in my application i should give them in GPS coordinates instead of (X,Y) like the simple example on top, adding the gps-ref to the code is the only change that should be done?

Sorry, the swig interface doesn't allow that yet. Recompile the f2c library, install it and try this:

gps_ref = f2c.Point(4.261999903178513,51.785970497504699)
field = f2c.Field()
field.setRefPoint(gps_ref)
f2c.Transform.transformToUTM(field)
path = f2c.Transform.transformToPrevCRS(dubins_path, field)

It should work now

@Gonzalo-Mier ,

Thanks, yes it works.
So, i can put directly the points of the swaths (path[i].addPoint(.....,.....) in the example) in gps coords ?

I don't understand what you want

I'll close the issue as it was solved. Feel free to open a new one if you have more doubts :)
