Special Use Airspace
OpenAirtm Airspace and Terrain description language is an easy to use
and publicly available standard for displaying map information.
User can add or modify the data himself, therefore having a full control over what is
being displayed on the screen.
For a list of available airspace files see our airspace directory.
NEW: WinPilot Version 1.130 and later:
In addition to 'Airspace.txt', now WinPilot also reads a file called 'Terrain.txt'.
Both files can contain all OpenAir commands.
The intention of the 'Terrain.txt' file is to separate terrain description
from airspace description.
The restriction of the maximum number of labels created by the AT command
has been changed from 3 to unlimited.
There are two new map elements meant for displaying
terrain and geographic features
(they differ from airspace in that they don't have popup labels attached):
TO {string} ; Declares Terrain Open Polygon; string -
name (optional)
TC {string} ; Declares Terrain Closed Polygon; string -
name (optional)
This commands make it easy to define things like lakes, roads, borders,
etc
For example, to draw a lake using light blue color and a dark blue 1-pixel
wide, solid border, that is visible at zoom levels 100km or closer, the
following commands can be used:
TC Lake Tahoe
SP 0, 1, 0, 0, 255
SB 200,200,255
V Z=100
DP 38:56:00 N 120:02:00 W
DP 38:56:40 N 120:04:00 W
DP 39:00:00 N 120:05:55 W
DP 39:01:45 N 120:07:00 W
DP 39:03:40 N 120:07:00 W
DP 39:05:00 N 120:09:00 W
DP 39:10:30 N 120:07:30 W
DP 39:11:00 N 120:06:00 W
...
The three new commands seen above are:
SP - Select Pen - corresponds to Win32 API CreatePen
SB -Select Brush - corresponds to Win32 API CreateSolidBrush
and V Z=number (select a zoom level above which the element will not be
displayed)
SP style, width, red, green, blue ; Selects Pen (border) to be used in drawing
PEN STYLES in SP command:
SOLID 0
DASH 1
NULL (transparent=no border displayed) 5
Example: for a 1 pixel wide, dashed, light gray pen use: SP
0,1,192,192,192
SB red, green, blue ; Selects Brush
(interior) red, green, blue can range from 0 (least intensity) to 255 (max
intensity)
Example: to select white interior of a closed
polygon, use: SB 255, 255, 255
To select transparent interior use: SB -1,-1,-1
The SP and SB commands can also be used to alter the default colors of airspace
segments.
For example, to change the default color of class C airspace from dark gray to
magenta, use: 'SB 180,0,180' in the first class C segment
definition, like this:
AC C
AN RENO-C
AL SFC
AH 8400 ft
SB 180,0,180 *select MAGENTA as the default for class C
V X=39:29.9 N 119:46.1 W
DC 5

=================================================
2018 : Update : Extensions Suggested by the Naviter Company:
The Open Air format is the current de-facto standard for editing airspace data for glider pilots worldwide
Create a new airspace format type which can easily be edited manually by pilots worldwide, possibly even use the already existing software.
The new format needs to be
Simple
Human readable
Editable in Notepad (this makes it hard to create controlled copies)
Extendable when new needs appear (and therefore XML?)
Be able to read AIXM format
Define parameters which are interesting for gliding / paragliding / hang gliding:
Define required airspace classes
A,B,C,D,E,F,G (independent from airspace types)
Define required airspace types (edit the table below):

Multiple lower and upper limits

Publish new airspace format and make it available to everybody
Create a web-based platform (Cloud) for storage and download
Put the responsibility for knowing which airspace is active to the pilot (which implies that more airspace management functions will be introduced in SeeYou)
AY = Airspace Type (extends AC which should now only be used for class)
