GPS detail level enumerations
In the XPack SDK we added more documentation about the enumerations relating to the GPS, but it looks like we left out some, too. Some people were investigating what each meant based on trial and error, but I think I can help out a bit here.
For example, Geoff_D was wondering what these numbers meant from the gps_500.xml:
<CustomDrawParam id="ObjectDetailLayerAirports" Name="ObjectDetailLayerAirports">
<Value>0 0 0 0 0 0 0x5 0x5 0x7 0x7 0x1F 0x1F 0x1F 0x1F 0x4F 0x4F 0x4F 0x4F 0x4F 0x4F 0x4F 0x4F 0x4F 0x4F 24 (@g:map_ZoomStep) case</Value>
So here's a quick runthrough that I just put together of what the numbers that you're scratching your head about mean:
· Detail level enumerations
o Airport
§ Dot = 1
§ Circle = 2
§ Circle and runways = 3
§ Block runways = 4
§ Airport runways = 5
o Vor
§ Dot = 1
§ Symbol = 2
o NDB
§ Dot = 1
§ Symbol = 2
o Airway
§ Thin lines = 1
§ Thick lines = 2
o Terrain
§ Water only = 1
§ Color = 2
o Approach
§ Approach = 1
§ Approach missed = 2
§ Approach arrow head = 4
o Flight plan
§ Solid line = 1
§ Dashed line = 2
o Vehicles
§ ATC symbol = 1
§ TCAS symbol = 2
§ Realistic symbol = 3
· Text detail level
o Airport
§ ICAO = 1
§ Name = 2
§ Name and elevation = 3
§ Name, elevation, and frequencies = 4
§ Runways = 5
o Vor
§ ID = 1
§ ID and frequency = 2
§ ID and morse code = 3
o ILS
§ ID = 1
§ ID and frequency = 2
§ ID and morse code = 3
o NDB
§ ID = 1
§ ID and frequency = 2
§ ID and morse = 3
o Vehicles
§ Realistic = 1
§ Detailed = 2
· Object detail level (flags and can be combined)
o Airport
§ Towered = 0x1
§ Not towered = 0x2
§ Hard runway = 0x4
§ Soft runway = 0x8
§ Water = 0x10
§ Heliports = 0x20
§ Private = 0x40
o VOR
§ VOR = 0x1
§ VOT = 0x2
o Marker
§ Outer marker = 0x1
§ Middle = 0x2
§ Inner = 0x4
§ Backcourse = 0x8
o Geopolitical
§ Coastline = 0x1
§ Boundary = 0x2
o Airway
§ Victor = 0x1
§ Jet = 0x2
o Flight plan
§ Enroute = 0x1
§ Approach = 0x2
§ Missed approach = 0x4
§ Waypoints = 0x8
o Vehicles
§ Track line = 0x1
§ Ground vehicles = 0x2
§ Airborne vehicles = 0x4
§ Racing vehicles = 0x8
o ILS
§ Cone = 0x1
§ Line = 0x2
So, to go back to Geoff_D's question:
<CustomDrawParam id="ObjectDetailLayerAirports" Name="ObjectDetailLayerAirports">
<Value>0 0 0 0 0 0 0x5 0x5 0x7 0x7 0x1F 0x1F 0x1F 0x1F 0x4F 0x4F 0x4F 0x4F 0x4F 0x4F 0x4F 0x4F 0x4F 0x4F 24 (@g:map_ZoomStep) case</Value>
0x5 = 0x1 | 0x4 = Towered and hard-runwayed airports
0x7 = 0x1 | 0x2 | 0x4 = Towered, untowered, and hard-runwayed airports.
0x1F = 0x1 | 0x2 | 0x4 | 0x8 | 0x10 = Towered, untowered, hard-runwayed, soft-runwayed, and water-based airports
and so forth...
In other words, the map is showing more and more airports as the user zooms in on the map (based on the value of @g:map_ZoomStep).
Thanks to Geoff_D for the question.
