+
The [[Legacy Astrographic Data]] is the chaotic set of sector and subsector data sets that arose during the period of 1977 to 2008.
 +
* [[Classic Traveller]] didn't arise as a planned science fiction setting. It developed into one.
 +
----
 +
Traveller star maps have gone through three overlapping and very generalized time periods of development:
 +
# [[Legacy Astrographic Data]] AKA [Initial Sectors (1977 to 2008)]
 +
# [[Sunbane]] AKA [Generated Data (1985 to 1999)]
 +
# [[T5 Second Survey]] AKA [Internet Era (1997 to Present)]

Traveller [[astrography]] is very difficult to document because it has had many overlapping periods about which even the direct eye witnesses and participants sometimes have profound disagreements. The legacy data is the interaction of the official publications, the work of the various Traveller licensees, and the fan works. Because these works fed into each other in various random ways, tracking the exact history of some of the data can be a difficult task. This author can only confess to having reviewed forty years of published materials, spoken with multiple former employees, authors, illustrators, and other participants and tried to piece the best history possible out of the mess. {{Unpublished cite|author=Maksim-Smelchak}}
+
The data for these sectors was originally generated by [[Joe Fugate]] and marked as copyright by both [[Digest Group Publications]] and {{GDW}}. The Sunbane data appears to be an inexact recreation of the [[Atlas of the Imperium]] data.
 +
 
 +
In addition, analysis of the data has shown several problems.
 +
# The number generator and generation algorithm were bad, producing a "needle stuck in a groove" effect.
 +
# For example, in [[Delphi Sector|Delphi]], 42 of the 346 (12%) worlds have [[UWP]] codes of "x10043x-x".
 +
# [[Massilia Sector|Massilia]] had thirteen worlds with [[TL-16]].

Rules for generation of astrographic data was included in [[Worlds and Adventures]] (1977), and could be used to generate map data (See TAS form 6, in the same book). The generation rules were expanded with the publication of [[Scouts (book)|Scouts]] (1983). There are several variations of system generation through each version of Traveller.

# In 1979 and 1981, the first full sector of data, including full maps, was published in [[The Spinward Marches]] (Supplement 3) (1979). And followed by [[The Solomani Rim]] (1981)
−
The first official publication of sector data was [[The Spinward Marches]] (1979) which has a full sector with maps. Several of the adventure books published by [[Games Designer Workshop]] includes excerpts from the The Spinward Marches book. For example [[The Kinunir]] (1979) has a full hex map of [[Regina Subsector]].
+
## There was no [[Charted Space]] when Classic Traveller first began.
−
 
+
## The Imperium board game (1977) is a precursor to the Imperium and it has a map. While it has a map, the data wasn't integrated into {{CT}} until a later time.
−
In 1980, [[Library Data (A-M)]] (1980) has the first full map of charted space (pages 23-24), but with no world locations.  
+
## [[The Kinunir]] (1979) has a full hex map of [[Regina Subsector]].
−
 
+
## [[Book 3]] contains a blank star chart (TAS Form 6). Book 3 also has a full hex map.
−
In 1981, [[Judges Guild]] published four sectors: [[Ley Sector (book)|Ley Sector]], [[Crucis Margin]], [[Maranantha-Alkahest Sector]], and [[Glimmerdrift Reaches]] which included 22"x34" maps and full data. These sectors have later been overwritten. Also in 1981, [[Paranoia Press]] published maps and data on two sectors: [[Beyond]] and [[Vanguard Reaches]].

In 1984, [[Games Designer Workshop]] produced [[Atlas of the Imperium]] incorporating previous data plus computer generated data, producing maps for 35 sectors of the Imperium. These contains system locations, and a few system details. The data behind the AotI has never been published and is presumed lost. [[Vargr (Alien Module)|Vargr]] (1984) published map and full data for the Gvurrdon sector.

### [[Old Expanses Sector]] 
−
In 1984, 1985, and 1986, each of the Alien modules ([[Aslan (Alien Module)|Aslan]], [[K'kree (Alien Module)|K'kree]], [[Vargr (Alien Module)|Vargr]], [[Zhodani (Alien Module)|}}, [[Droyne (Alien Module)|Droyne]], [[Solomani (Alien Module)|Solomani]], and [[Hivers (Alien Module)|Hivers]]) contained more detailed maps including some sector names, but no additional data.
+
### [[Reaver's Deep Sector]]
−
 
+
### [[Reft Sector]] 
−
Source of data was in physically published works. In addition to the many works of [[Game Designers' Workshop]], and the several licensees, there were several fanzines also publishing astrographic data. Access to data required knowledge of the publishers and purchase of the physical media.

## Many early legacy publishers created a variety of settings, maps, and materials, some of which has never been officially placed within the [[OTU]].
 +
# In 1984, each of the Alien modules (Zhodani, K'kree, Vargr, Aslan, Solomani, Hiver) contained a more detailed map including sector names, but still without data. [[Vargr (Alien Module)]] (1984) published map and full data for the Gvurrdon sector.

[[Digest Group Publications]], a Traveller Licensee, with the publication of [[The Travellers' Digest]] (1985) magazine generated several sectors of data. In total they generated 35 sectors of data. They reverse engineered the AotI maps to some success. This data was used in their various of the DGP publications throughout their history. The data was used as the basis for the dot maps in [[Alien - Solomani & Aslan | Solomani & Aslan]] and [[Alien - Vilani & Vargr|Vilani & Vargr]].

[[Alien - Vilani & Vargr|Vilani & Vargr]] (1990) and [[Alien - Solomani & Aslan|Solomani & Aslan]] (1991) include detailed dot maps, showing the location of star systems across most of the charted space map. Other than the GEnie Sectors, this data was never released. Fans have reverse-engineered this data.

The [[History of the Imperium Working Group]], founded in 1987 with the publication of MegaTraveller, had the explicit goal to document the future history of the Third Imperium. This would include all aspects of the Traveller universe. This data was shared via the physically mailing floppy disks containing various documents.

# HIWG divided [[charted space]] into four quadrants, and several smaller sections. These sections were claimed by members of HIWG for development and detailing.
 +
# This data was widely shared by CD-ROM and snail mail meaning that there are many, many variations of it within the greater community.
 +
# When the GEnie data was published, {{HIWG}} members updated and added to many of these sectors. They added names and stellar data to most of the data (missing in the original), and expanded upon the original 35 sectors.
 +
# During it's history, HIWG members add data for more than 100 sectors, expanding on the initial 35 sectors. It is the largest addition of sector data in the history of Traveller. The hard work of the [[HIWG]] to enhance and extend the data has been a true credit to the community.
 +
# In addition to expanding the original GEnie data, the members also reverse engineered and generated data for most of the sectors published in V&V and S&A.
 +
# The GEnie and HIWG expanded data continues to be used widely by Traveller fans for their projects. The [[Hinterworlds Sector]] article in [[Challenge39|Challenge 39]] used the data as its starting point. The data for the [[Domain of Gateway| Gateway Domain]] sectors was used as the starting point for [[Gateway to Destiny]]. It served as the basis for the [[T5 Second Survey]].
 +
# The data, as updated by {{HIWG}}, is distributed with [[Galactic]] and [[Heaven & Earth]], two of the most popular Traveller mapping programs. It forms the basis for numerous online maps. Many of the files at the [http://zho.berka.com/ Zhodani Base] web site use the data.

=== Early Internet Era ===
 
 
From the late 1980's to the early 1990s, access to data during required knowledge of the pre-web internet, including subscribing to the [[TML]] or other mailing lists, knowledge of various FTP sites, and being a member of online services like CompuServe or GEnie. Most people still had access to data only via the published works.

# In the late 1980s and throughout the 1990s, additional variations on the maps occurred from the [[MT]], [[TNE]], and [[T4]] settings. Some of these changes were chronological ones and others actually changed star positions, world names, or more significant astrophysical adjustments.
−
From the late 1980s and through the 1990s additional variations on maps and data occurred from the [[MegaTraveller]], [[Traveller The New Era]], and [[Marc Miller's Traveller]] settings. The Traveller fan base also continued to generate, refine, and update parts of the data.

# As it was posted on various sites, more variation occurred including a great deal from the Zhodani Base, which still thankfully hosts [[Galactic]] files.
−
From around 2001 to around 2016, there were several additional projects such as [[Clifford Linehan]]'s [[Core Expedition|Core Route project]], generating data and publishing it online. Other projects were generating data for the edges of charted space including the Vargr Extents,  
+
# As the various Traveller publishers during this era would publish books, the data would be transcribed into various online forms and re-distributed. Some of the changes and variations created significantly different maps.

=== T5 Second Survey ===
+
# In the 1990s, there were two main software programs used for viewing, generating, and manipulation the astrographic data: [[Galactic]] (1996) and [[Heaven & Earth]] (1999). These programs are distributed with the HIWG updated sector data along with several published data sets ([[TNE]], [[T4]]) and fan generated projects. Different releases of the programs have different version of data depending upon what was available to the developers at the time.
−
With the publication of the playtest version of the [[Traveller 5th]] edition core rule book (2008), [[Don McKinney]], [[Robert Eaglestone]], along with [[Marc Miller]] engaged in a project to collect and update the known astrographic data. Since the original three members, others have joined and left this ongoing project. The project was to identify and correct consistency errors between Sunbane and AOTI astrographic data.
 
−
 
 
−
The [[T5 Second Survey]] mandate originally included the 35 sectors of the Imperium. The project completed in 2012 with publication to the Traveller Map site. From there the project as continued with an expanded mandate to support any of the Traveller publishers to produce a consistent astrographic data set.
 
−
 
 
−
Despite the presence of the T5 Second Survey players continue to enjoy the process of generating worlds and sector data as part of the Traveller Universes publishing their efforts on line.
