Discussion Discovering which layout each Odyssey settlement is

Hello players, and especially hello developers.

It is widely believed that there are 28 Odyssey settlement layouts, 4 Tourist, 5 Agri, 5 Military, 5 Industrial, 5 Extraction and 4 High Tech.

Even though there are many thousands of actual settlements, each one is laid out as one of these 28.

is there any data / log / ID / journal etc etc that holds what type of settlement layout each settlement is

I would like to write an app that would identify which settlement layout you are approaching / landing at.

The investigation I have done so far is based on the 'MarketID' of the "ApproachSettlement" event in the game logs. I compared the MarketID of several settlements that I know to have the same layout, looking for patterns / similarities in their MarketIDs but so far have come up empty.

My eventual plan is to integrate this identify the layout into the Odyssey Map Guide (https://www.quizengine.co.uk/omg/), such that as you approach a settlement, OMG would autoshow the settlement type you are landing at.
 
It may need to be user-submitted to some extent, though there are certain shortcuts.
The size of the largest landing pad according to Inara or similar*:
EconomySML
Agriculture2, 5n/a1, 3, 4
Extraction541, 2, 3
High Tech2, 3, 4n/a1
Industrial132, 4, 5
Military41, 3, 52
Tourismn/a21, 3, 4
*note: Inara pad sizes will often incorrectly be listed as S if the settlement hasn't been updated by visiting it while running EDD/EDMC/etc., so a good rule of thumb is to not trust the listed pad size if there's any other missing or incorrect data for that settlement (e.g. missing faction/government/economy, mismatch between faction and government, etc.)

The number of "+"s at the end of the settlement's name is also directly dependent on layout.
Economy(0)+ (1)++ (2)
Agriculture21, 53, 4
Extraction52, 41, 3
High Tech23, 41
Industrial13, 4, 52
Military13, 4, 52
Tourism23, 41

This information can be used to differentiate between most settlement layouts without having to actually approach them. The following are the only ones that can't be differentiated with only this information:
Agr ++: 3 or 4
Ext ++: 1 or 3
HiT +: 3 or 4
Ind L +: 4 or 5
Mil M +: 3 or 5
Tou +: 3 or 4

The security level of a settlement (the shield icon next to the name) is NOT directly dependent on layout; for example, the Ngurii system has two Ind1 settlements with medium security and one with high, one HiT2 settlement with medium security and one with low, one Mil4 settlement with low security and one with high.

What I don't know is what effect (if any) security level has on loot quantity/quality, dataport positioning, etc.. I also haven't paid close enough attention to see if settlements of the same layout always have the same number of dataports (either of each type or in total), though I have observed dataports being in different places (or not present at all) in different settlements of the same layout.

Hopefully this provides some interesting and helpful avenues of study!

Maybe with combination of the pad counts:

1Agriculture,Extraction,High Tech,Industrial,Military
3High Tech
1Extraction,Industrial,Military,Tourism
11Military
1Agriculture,Extraction,Industrial

If there's a way to retrieve pad counts per size for any given settlement from the API or otherwise determine it (in-game or otherwise) without physically going down to the settlement and visually checking, this could be useful, but otherwise it's effectively the same as comparing screenshots (or possibly worse, since there may still be settlements of the same economy and size that also have the same pad counts)
 
Finally found a HiT4 settlement so I could finish out that second table today, and added some additional notes. Will probably make a flowchart or two at some point.

I've also started collecting data on dataport counts per layout, and I can definitely say at this point that not all settlements of the same layout will always have the same number of each type of dataport, but I don't have enough data to determine if there are any factors that affect it within a given layout. Dataport counts for a single settlement do seem to be consistent across Thursday server resets, though, so there is at least value in recording dataport counts on a per-settlement basis for purposes of picking the best places to scavenge from.

The first release of OMG had dataport locations in. It was a while later that I discovered that the dataport locations are subject to RNG positioning, so I took them out for 1.1

I can now confirm that dataport counts can differ even between settlements of the same layout, same superpower, same faction, same security level, and even the same system.

A bit disappointing tbh, but it should at least theoretically be possible to establish upper and lower bounds for dataport counts on a per-layout basis, though this will likely require a lot of samples.
