- NOTE: The following is a revised version of the proposed naming guidelines for
- scenery and related files developed through the use of ASD. The changes are
- principally reflected at the use of indicator codes in lieu of airport or
- navaid designators, where appropriate.
-
- PROPOSED NAMING SYSTEM FOR ASD FILES
-
- CPAA is considering inviting users of the new Aircraft And Scenery
- Designer add-on to send their favorite files for distribution among
- interested parties, either by electronic means or by the distribution
- of duplicated disks, for just the cost of duplication and handling.
-
- In order to do that, we've considered the adoption of the following
- naming convention. (Members know how involved we can get with numbering
- conventions!)
-
- A typical FILE name would look like this:
-
- "VAAJYOJB.SC1"
-
- Looks like gibberish, but actually it packs a lot of info. The interpretation
- is this:
-
- 1. First 2 letters are the two-digit accepted abbreviation for the
- state in which the scenery is located. We selected states rather than
- scenery disks, because it doesn't matter if you have a scenery disk
- or not...you can build scenery ANYWHERE, since you're not modifying
- existing data. This was a suggestion by Jon Solon, of Microsoft, and
- makes a lot of sense to us. Especially considering you can also locate
- objects by using their latitude and longitude coordinates rather than
- the FS North/South coordinates.
-
- 2. The third letter is the "Category Code", and is derived from a category
- listing, depending on the type of scenery file and it's principle
- characteristic. The Category List is:
-
- A=Airport
-
- N=Navaid (VOR/NDB)
-
- F=Fantasy scenery (meaning unusual, imaginary or "absurd"-"alternate
- reality")
-
- S=Scenic, meaning a more or less serious (maybe wistful) depiction of an
- object, location or area
-
- 3. The next three digits are used to more completely describe the file, and
- may be used in a variety of ways:
-
- A. When either "A", "V" or "N" are used as the "Category Code", with the focal
- point of the file being A PARTICULAR navaid or an airport, the accepted
- location identifier for the location, would be used. In the example filename
- above, the "JYO" is the three-digit identifier for Leesburg Airport, which
- happens to be the focal point of that particular scenery file. Should the
- designer not know the appropriate identifier, he or she could simply
- substitute the letters "XXX", and CPAA will insert the appropriate code upon
- receipt of the file. We have complete data on all location identifiers in the
- US and much of Canada and Europe. We can either provide that information on
- request, or can change the filename accordingly when we receive a file.
-
- If the navaid category is used to indicate a MULTIPLE number of navaids, the
- letters "WPT", signifying "Waypoints" could be used. This may be, for example,
- a "corridor" through scenery areas not yet covered in the default scenery or
- in scenery disks. This would be a file that would include ONLY the Navaids and
- two or more en route airports. There is no current location assigned the
- letters "WPT", so those letters will not be confused for a given location.
-
- B. When "F" is used as the Category Code, any of the following 3-digit
- "descriptors" could be used:
-
- MIX=Mixture of wide variety of more or less "standard" ASD objects
-
- EXP=Experimental Objects; major variations with unique application of ASD
- tools.
-
- DRM=Idealized depiction of an area or feature, such as a "Dream House", or
- "Fantasy Island".
-
- C. When "S" is used as the Category Code, any of the following 3-digit
- "descriptors" could be used:
-
- CTY=When the focal point is a city or other populated area; file consists
- mainly of buildings, roadways, etc.
-
- MTN=When focal point is in the use of mountains, lakes, rivers, etc.
-
- ISL=When focal point is a "real world" island, and has been more or less
- faithfully reproduced
-
- WAY=When the purpose of a file is to provide a "corridor" of visual
- references through which a user can fly between two locations,
- through an area not currently covered by either the default scenery
- or scenery disks. This would largely consist of roads, rivers or
- railways, and objects such as mountains, lakes, and polygons
- representing cities. It could also include two or more airports.
- (See next paragraph for another use of the
-
- 4. The final two digits are the author's first and last initials, so as to
- minimize the chances of duplicate file names being generated by separate
- individuals who happen to prepare a scenery file for the same location.
-
- This sort of naming convention seems to offer a reasonable chance of success
- at organizing a mass of files such as this. It is easily "searchable", using
- DOS wildcards, and fairly simple in operation.
-
- It should be noted that the naming convention proposed makes use of the full
- eight-digit DOS naming procedure, rather than the 6-digit names used on
- CompuServe. Not only does the full eight digits allow greater precision in
- naming, but it also was used because it is expected that a lot of file-sharing
- will take place outside of the CIS environment, through disk transfers,
- through BBS feeds, and direct modem-to-modem links between individuals, and
- the six-digit limit would not be applicable.
-
- For purposes of CIS transfers, it has been suggested that uploads of .SC1
- files be done in a compressed format, which makes it possible to include
- several files in one uploadable .ZIP file. Given the six-digit limit, then,
- the CIS-uploadable .ZIP file name could easily be a truncated version of the
- full 8-digit DOS-level file name, by eliminating the last two digits (the
- author's initials). In addition to the .SC1 file, and an associated .DY1 file,
- the .ZIP file could contain the associated mode and/or demo file to run with
- the scenery, and a documentation file, which explains the files usage and
- describes its contents. It could also contain a specific aircraft .SIM file,
- if one is required to run with the supplied demo or mode. The full eight-digit
- name can be retained within the .ZIP file.
-
- For example, the contents of a CIS-uploadable file named "VAAJYO.ZIP" could be
- as follows:
- VAAJYOJB.SC1 - Static Scenery file
- VAAJYOJB.MOD - Mode file
- VAAJYOJB.DOC - Documentation file
- VAAJYOJB.DY1 - Associated Dynamic Scenery File
- *.SIM - Associated aircraft file required by the mode or demo
-
- Comments re CIS are included here as a fair number of CIS files ahve
- found their way here and we may well reciprocate.
-
- Please dont hesitate to comment regarding these conventions
