ICARD 5LNC and Operational
Data
ICAO GIS analysis
Overview
We receive new Waypoint Data from our
client
The new Waypoint Data is converted into a
.shp format and integrated in the original
data in order to construct updated map with
most key layers visualized…
The new ICARD5LNC ICAO database layer
is compared with the Operational Data layer
Comparison findings: Many discrepancies
between the two data .
ICAO5LNC History?
Originally States used ”The Green Book”
to choose and reserve a 5LNC. The consequence:
many duplicates between regions and coordinate
mistakes recorded in the 5LNC data base .
The calculation of the coordinate location at that time
did not follow a geodesic procedure. Regularly the
coordinates of a 5LNC were grid intersections on large
scale map. The Degrees Minutes and Seconds were
read and recorded manually using a divided compass
tool…
Result: 5LNC data is inaccurate with varied coordinate
precision between 2 and 6 digits. Records are very
different to the real world operational coordinate data.
The term Coordinate Precision refers to the mathematical exactness
of a coordinate and is based on the possible number of significant digits
that can be stored for each coordinate.

ICARD 5LNC and Operational
Data
ICAO GIS analysis
Overview
We receive new Waypoint Data from our
client
The new Waypoint Data is converted into a
.shp format and integrated in the original
data in order to construct updated map with
most key layers visualized…
The new ICARD5LNC ICAO database layer
is compared with the Operational Data layer
Comparison findings: Many discrepancies
between the two data .
ICAO5LNC History?
Originally States used ”The Green Book”
to choose and reserve a 5LNC. The consequence:
many duplicates between regions and coordinate
mistakes recorded in the 5LNC data base .
The calculation of the coordinate location at that time
did not follow a geodesic procedure. Regularly the
coordinates of a 5LNC were grid intersections on large
scale map. The Degrees Minutes and Seconds were
read and recorded manually using a divided compass
tool…
Result: 5LNC data is inaccurate with varied coordinate
precision between 2 and 6 digits. Records are very
different to the real world operational coordinate data.
The term Coordinate Precision refers to the mathematical exactness
of a coordinate and is based on the possible number of significant digits
that can be stored for each coordinate.

ICARD 5LNC and Operational
Data
ICAO GIS analysis
Overview
We receive new Waypoint Data from our
client
The new Waypoint Data is converted into a
.shp format and integrated in the original
data in order to construct updated map with
most key layers visualized…
The new ICARD5LNC ICAO database layer
is compared with the Operational Data layer
Comparison findings: Many discrepancies
between the two data .
ICAO5LNC History?
Originally States used ”The Green Book”
to choose and reserve a 5LNC. The consequence:
many duplicates between regions and coordinate
mistakes recorded in the 5LNC data base .
The calculation of the coordinate location at that time
did not follow a geodesic procedure. Regularly the
coordinates of a 5LNC were grid intersections on large
scale map. The Degrees Minutes and Seconds were
read and recorded manually using a divided compass
tool…
Result: 5LNC data is inaccurate with varied coordinate
precision between 2 and 6 digits. Records are very
different to the real world operational coordinate data.
The term Coordinate Precision refers to the mathematical exactness
of a coordinate and is based on the possible number of significant digits
that can be stored for each coordinate.

ICARD 5LNC and Operational
Data
ICAO GIS analysis
Overview
We receive new Waypoint Data from our
client
The new Waypoint Data is converted into a
.shp format and integrated in the original
data in order to construct updated map with
most key layers visualized…
The new ICARD5LNC ICAO database layer
is compared with the Operational Data layer
Comparison findings: Many discrepancies
between the two data .
ICAO5LNC History?
Originally States used ”The Green Book”
to choose and reserve a 5LNC. The consequence:
many duplicates between regions and coordinate
mistakes recorded in the 5LNC data base .
The calculation of the coordinate location at that time
did not follow a geodesic procedure. Regularly the
coordinates of a 5LNC were grid intersections on large
scale map. The Degrees Minutes and Seconds were
read and recorded manually using a divided compass
tool…
Result: 5LNC data is inaccurate with varied coordinate
precision between 2 and 6 digits. Records are very
different to the real world operational coordinate data.
The term Coordinate Precision refers to the mathematical exactness
of a coordinate and is based on the possible number of significant digits
that can be stored for each coordinate.

ICARD 5LNC and Operational
Data
ICAO GIS analysis
Overview
We receive new Waypoint Data from our
client
The new Waypoint Data is converted into a
.shp format and integrated in the original
data in order to construct updated map with
most key layers visualized…
The new ICARD5LNC ICAO database layer
is compared with the Operational Data layer
Comparison findings: Many discrepancies
between the two data .
ICAO5LNC History?
Originally States used ”The Green Book”
to choose and reserve a 5LNC. The consequence:
many duplicates between regions and coordinate
mistakes recorded in the 5LNC data base .
The calculation of the coordinate location at that time
did not follow a geodesic procedure. Regularly the
coordinates of a 5LNC were grid intersections on large
scale map. The Degrees Minutes and Seconds were
read and recorded manually using a divided compass
tool…
Result: 5LNC data is inaccurate with varied coordinate
precision between 2 and 6 digits. Records are very
different to the real world operational coordinate data.
The term Coordinate Precision refers to the mathematical exactness
of a coordinate and is based on the possible number of significant digits
that can be stored for each coordinate.

ICARD 5LNC and Operational
Data
ICAO GIS analysis
Overview
We receive new Waypoint Data from our
client
The new Waypoint Data is converted into a
.shp format and integrated in the original
data in order to construct updated map with
most key layers visualized…
The new ICARD5LNC ICAO database layer
is compared with the Operational Data layer
Comparison findings: Many discrepancies
between the two data .
ICAO5LNC History?
Originally States used ”The Green Book”
to choose and reserve a 5LNC. The consequence:
many duplicates between regions and coordinate
mistakes recorded in the 5LNC data base .
The calculation of the coordinate location at that time
did not follow a geodesic procedure. Regularly the
coordinates of a 5LNC were grid intersections on large
scale map. The Degrees Minutes and Seconds were
read and recorded manually using a divided compass
tool…
Result: 5LNC data is inaccurate with varied coordinate
precision between 2 and 6 digits. Records are very
different to the real world operational coordinate data.
The term Coordinate Precision refers to the mathematical exactness
of a coordinate and is based on the possible number of significant digits
that can be stored for each coordinate.

ICARD 5LNC and Operational
Data
ICAO GIS analysis
Overview
We receive new Waypoint Data from our
client
The new Waypoint Data is converted into a
.shp format and integrated in the original
data in order to construct updated map with
most key layers visualized…
The new ICARD5LNC ICAO database layer
is compared with the Operational Data layer
Comparison findings: Many discrepancies
between the two data .
ICAO5LNC History?
Originally States used ”The Green Book”
to choose and reserve a 5LNC. The consequence:
many duplicates between regions and coordinate
mistakes recorded in the 5LNC data base .
The calculation of the coordinate location at that time
did not follow a geodesic procedure. Regularly the
coordinates of a 5LNC were grid intersections on large
scale map. The Degrees Minutes and Seconds were
read and recorded manually using a divided compass
tool…
Result: 5LNC data is inaccurate with varied coordinate
precision between 2 and 6 digits. Records are very
different to the real world operational coordinate data.
The term Coordinate Precision refers to the mathematical exactness
of a coordinate and is based on the possible number of significant digits
that can be stored for each coordinate.

Questions and Comments
To create an effective ICARD INITIALISATION
• We must correct the present ICARD5LNC DATABASE
following measures proposed in the “ICAO to do list”
Compare complete ICARD5LNC data with respect to the
existing operational data and considering coordinate
precision, duplicates and other found errors.
• Verify ICARD5LNC waypoints that intersect

ICARD 5LNC and Operational
Data
ICAO GIS analysis
Overview
We receive new Waypoint Data from our
client
The new Waypoint Data is converted into a
.shp format and integrated in the original
data in order to construct updated map with
most key layers visualized…
The new ICARD5LNC ICAO database layer
is compared with the Operational Data layer
Comparison findings: Many discrepancies
between the two data .
ICAO5LNC History?
Originally States used ”The Green Book”
to choose and reserve a 5LNC. The consequence:
many duplicates between regions and coordinate
mistakes recorded in the 5LNC data base .
The calculation of the coordinate location at that time
did not follow a geodesic procedure. Regularly the
coordinates of a 5LNC were grid intersections on large
scale map. The Degrees Minutes and Seconds were
read and recorded manually using a divided compass
tool…
Result: 5LNC data is inaccurate with varied coordinate
precision between 2 and 6 digits. Records are very
different to the real world operational coordinate data.
The term Coordinate Precision refers to the mathematical exactness
of a coordinate and is based on the possible number of significant digits
that can be stored for each coordinate.

ICARD 5LNC and Operational
Data
ICAO GIS analysis
Overview
We receive new Waypoint Data from our
client
The new Waypoint Data is converted into a
.shp format and integrated in the original
data in order to construct updated map with
most key layers visualized…
The new ICARD5LNC ICAO database layer
is compared with the Operational Data layer
Comparison findings: Many discrepancies
between the two data .
ICAO5LNC History?
Originally States used ”The Green Book”
to choose and reserve a 5LNC. The consequence:
many duplicates between regions and coordinate
mistakes recorded in the 5LNC data base .
The calculation of the coordinate location at that time
did not follow a geodesic procedure. Regularly the
coordinates of a 5LNC were grid intersections on large
scale map. The Degrees Minutes and Seconds were
read and recorded manually using a divided compass
tool…
Result: 5LNC data is inaccurate with varied coordinate
precision between 2 and 6 digits. Records are very
different to the real world operational coordinate data.
The term Coordinate Precision refers to the mathematical exactness
of a coordinate and is based on the possible number of significant digits
that can be stored for each coordinate.
