Converts an angle measured in degrees to an equivalent angle measured in radians.
Converts an angle measured in radians to an equivalent angle measured in degrees.
Returns a new string that is a substring of the value with given begin and end index
Returns the length of a string.
Returns the string converted to uppercase.

Extracts the year part of the date
Extracts the month part of the date
Returns the week number of the date
Extracts the day part of the date
Returns the hour of the date
Returns the minute of the date
Returns the second of the date
Return the current system time specific date
Returns the difference, measured in milliseconds, between the current time and midnight, January 1, 1970 UTC
Returns the current value of the time source, in nanoseconds.
Converts the given double value to a short value
Converts the given double value to a byte value
Converts the given double value to a float value
Converts the given double value to a long value
Converts the given value to a short value. This function converts any value to a short value, thus it is more time consuming than the DoubleToShort function for double values.
Converts the given value to a byte value. This function converts any value to a byte value, thus it is more time consuming than the DoubleToByte function for double values.
Converts the given value to a float value. This function converts any value to a float value, thus it is more time consuming than the DoubleToFloat function for double values.
Converts the given value to a long value. This function converts any value to a long value, thus it is more time consuming than the DoubleToLong function for double values.
Calculates an MD5 checksum for the string.
Calculates an SHA-1 checksum for the string.
Calculates an SHA-265 checksum for the string.
Returns a Universal Unique Identifier (UUID).
The following MEP functions are not part of the Odysseus Core and may be restricted.
Transform the list of spatial polar coordinates into a list of Cartesian coordinates
Returns the centroid of the given geometry
Creates a buffer of the given size around the given geometry
Checks whether the first geometry contains the second geometry.
Computes the smallest convex spatial polygon
that contains all the points in the geometry
Transforms the given spatial polar coordinate into a spatial Cartesian coordinate.
Transforms the given spatial Cartesian coordinate into a polar coordinate
The MoveViewPoint has 2 parameter: A geometry and the new origin of the new view point.
The RotateViewPoint has 2 parameter: A geometry and the rotation angle in radians for the new view point.
The ToGrid function has 5 parameter: A geometry defining the free and occupied area, the origin of the grid, the width and height of the grid in cells, and the size of a cell.
The RotateGrid has 2 parameter: A grid and the rotation angle in radians. The result is the rotated grid.
The SpreadOccupancyGrid function takes 4 parameters: A cartesian grid, the timestamp of the grid, the current timestamp, and the velocity of objects in the environment.
The MergOccupancyGrid function takes 6 parameters: A cartesian grid, the polar coordinates, the origin, the transform angle, the polar radius, and the polar cellsize.
Estimates the multivariate normal distribution probability with lower and upper integration limit.
The ClassifyObject functions takes multiple segments as a spatial multi line string and performs a classification of the line strings. The result of the function is a list of classified objects
