Abstract

Systems and methods for processing Airport Mapping Database (AMDB) data are provided. The systems include a guidance element database accessible by an aircraft surface movement guidance system, and a controller functionally coupled to the guidance element database and configured to, by one or more processors: receive AMDB data from an AMDB, wherein the AMDB data includes aerodrome surface elements of an airport including guidance lines associated with regions of the airport, preprocess the AMDB data to fuse at least some of the aerodrome surface elements and thereby produce fused AMDB data indicative of fused aerodrome surface elements, process the AMDB data and the fused AMDB data to determine guidance elements including one or more single paths and/or zones for at least some of the regions of the airport, and store the guidance elements in the guidance element database.

First claim

What is claimed is:

1 . A method, comprising:
receiving, by a controller having one or more processors, AMDB data from an airport mapping database (AMDB), wherein the AMDB data includes aerodrome surface elements of an airport including guidance lines associated with regions of the airport; preprocessing, by the controller with the one or more processors, the AMDB data to fuse at least some of the aerodrome surface elements and thereby produce fused AMDB data indicative of fused aerodrome surface elements; processing, by the controller with the one or more processors, the AMDB data and the fused AMDB data to determine guidance elements including one or more single paths and/or zones for at least some of the regions of the airport; and storing, by the controller with the one or more processors, the guidance elements in a guidance element database.

2 . The method of claim 1 , wherein preprocessing the AMDB data includes, by the controller with the one or more processors, modifying at least a first guidance line of the guidance lines disposed within a first region of the airport that includes an overshoot or an undershoot relative to an adjacent boundary of the first region by extending or shortening, respectively, the first guidance line to end at the adjacent boundary.

3 . The method of claim 1 , wherein preprocessing the AMDB data includes, by the controller with the one or more processors, removing at least a first guidance line of the guidance lines that extends onto an apron of the airport.

4 . The method of claim 1 , wherein preprocessing the AMDB data includes, by the controller with the one or more processors, determining a direction of travel of the guidance lines.

5 . The method of claim 1 , wherein preprocessing the AMDB data includes, by the controller with the one or more processors, segmenting at least a first guidance line and a second guidance line of the guidance lines that contact each other at an intersecting point therebetween.

6 . The method of claim 1 , wherein preprocessing the AMDB data includes, by the controller with the one or more processors, fusing at least a first guidance line and a second guidance line of the guidance lines that are aligned but segmented due to a hold line of the airport.

7 . The method of claim 1 , wherein preprocessing the AMDB data includes, by the controller with the one or more processors, removing at least a first guidance line and a second guidance line of the guidance lines that diverge from each other near a boundary of a first region of the regions of the airport.

8 . The method of claim 1 , wherein processing the fused AMDB data to determine the guidance elements includes, by the controller with the one or more processors, linking at least a first guidance line of the guidance lines with a boundary of a first region of the regions of the airport in which the first guidance line is disposed.

9 . The method of claim 1 , wherein processing the fused AMDB data to determine the guidance elements includes, by the controller with the one or more processors, combining at least a first guidance line and a second guidance line of the guidance lines that are aligned within a non-intersection taxiway of the airport to define a first single path of the one or more single paths.

10 . The method of claim 1 , wherein processing the fused AMDB data to determine the guidance elements includes, by the controller with the one or more processors, determining a first zone of the one or more zones for a taxiway of the airport having two or more non-aligned guidance lines therein, wherein the first zone includes common points between the two or more non-aligned guidance lines.

11 . A system, comprising:
a guidance element database accessible by an aircraft surface movement guidance system; and a controller functionally coupled to the guidance element database and configured to, by one or more processors:
receive AMDB data from an airport mapping database (AMDB), wherein the AMDB data includes aerodrome surface elements of an airport including guidance lines associated with regions of the airport;
preprocess the AMDB data to fuse at least some of the aerodrome surface elements and thereby produce fused AMDB data indicative of fused aerodrome surface elements;
process the AMDB data and the fused AMDB data to determine guidance elements including one or more single paths and/or zones for at least some of the regions of the airport; and
store the guidance elements in the guidance element database.

12 . The system of claim 11 , wherein the controller is configured to, with the one or more processors, preprocess the AMDB data, at least in part, by modifying at least a first guidance line of the guidance lines disposed within a first region of the airport that includes an overshoot or an undershoot relative to an adjacent boundary of the first region by extending or shortening, respectively, the first guidance line to end at the adjacent boundary.

13 . The system of claim 11 , wherein the controller is configured to, with the one or more processors, preprocess the AMDB data, at least in part, by removing at least a first guidance line of the guidance lines that extends onto an apron of the airport.

14 . The system of claim 11 , wherein the controller is configured to, with the one or more processors, preprocess the AMDB data, at least in part, by determining a direction of travel of the guidance lines.

15 . The system of claim 11 , wherein the controller is configured to, with the one or more processors, preprocess the AMDB data, at least in part, by segmenting at least a first guidance line and a second guidance line of the guidance lines that contact each other at an intersecting point therebetween.

16 . The system of claim 11 , wherein the controller is configured to, with the one or more processors, preprocess the AMDB data, at least in part, by fusing at least a first guidance line and a second guidance line of the guidance lines that are aligned but segmented due to a hold line of the airport.

17 . The system of claim 11 , wherein the controller is configured to, with the one or more processors, preprocess the AMDB data, at least in part, by removing at least a first guidance line and a second guidance line of the guidance lines that diverge from each other near a boundary of a first region of the regions of the airport.

18 . The system of claim 11 , wherein the controller is configured to, with the one or more processors, process the fused AMDB data to determine the guidance elements, at least in part, by linking at least a first guidance line of the guidance lines with a boundary of a first region of the regions of the airport in which the first guidance line is disposed.

The system of claim 11 , wherein the controller is configured to, with the one or more processors, process the fused AMDB data to determine the guidance elements, at least in part, by combining at least a first guidance line and a second guidance line of the guidance lines that are aligned within a non-intersection taxiway of the airport to define a first single path of the one or more single paths.

20 . The system of claim 11 , wherein the controller is configured to, with the one or more processors, process the fused AMDB data to determine the guidance elements, at least in part, by determining a first zone of the one or more zones for a taxiway of the airport having two or more non-aligned guidance lines therein, wherein the first zone includes common points between the tw
