PyANGKernel.GKCoordinateTranslator.defaultCS
__init__(model)
Parameters:

model – GKModel

convert(fromCS, toCS, b)
Parameters:

  • fromCS – str

  • toCS – str

  • b – GKBBox

Return type:

GKBBox

Converts a bbox from a CS to another

convert(fromCS, toCS, p)
Parameters:

  • fromCS – str

  • toCS – str

  • p – GKPoint

Return type:

GKPoint

Converts a point from a CS to another

static getCSFromUTM(zone, northing)
Parameters:

  • zone – int

  • northing – bool

Return type:

str

Returns the EPSG code from a WGS 84 UTM zone as a string with the format EPSG:XXXX

maybeSetModelCSFromData(topWidget, newCS, leftMostPoint)
Parameters:

  • topWidget – QWidget

  • newCS – str

  • leftMostPoint – GKPoint

Return type:

bool

Importing data from an external source with a CS. If this CS is: * - Unprojected: either set the projected CS from data (UTM) or keep the model CS * - Projected: either set the CS ot keep the model one

toDegrees(p)
Parameters:

p – GKPoint

Return type:

GKPoint

Converts a point in m to longitude (X) and latitude (Y) using the model coordinate system

toMeters(pts)
Parameters:

pts – GKPoints

Converts a vector of points from the default degree CS (“EPSG:4326”) to the model coordinate system. The input vector is modified

toMeters(p)
Parameters:

p – GKPoint

Return type:

GKPoint

Converts a point from the default degree CS (“EPSG:4326”) to the model coordinate system. The point to be converted should be defined as GKPoint ( latitude, longitude ).

toMeters(fromCS, p)
Parameters:
Return type:

GKPoint

Converts a point from a CS to the model coordinate system. UnknownCommand GKModel::getDefaultCS.

toMeters(units, p, fromCS)
Parameters:
Return type:

GKPoint

Converts a point from “units” to m. Entry point is in fromCS coordinate system. The destination * coordinate system is the one defined in the model. UnknownCommand GKModel::getDefaultCS.

validateCSForAimsunMap(cs)
Parameters:

cs – str

Return type:

str

See if the CS can be used as the Aimsun model CS. Must be projected and in meters. * Returns an error explanation or an empty string if it is OK.
