An update to the official game map

Yeah, I also wouldn't worry about HK too much. The base is most important in 12/41, but rarely gets much attention after that.

I completely disagree with that statement.

HK is a level 9 port, with a useful shipyard. It is the crux of the allied overland drive that liberates Malaya/Indochine/southeast China in 1943-early 44. Supplied by rail and primary road all the way up the Asian littoral magic highway from Singapore, it becomes the Allied base driving the sea-air control campaign into the China Sea, where the Asian littoral strategy is prioritised.

Have you never seen that strategy employed?

Hmmm, I personally have not employed that strategy before.
Also I haven't seen it deployed in the AARs that I had read. (At least I can't remember)
Seems like I have missed that one until now.

Reading about it does make it sound like a good strategy though.
I stand corrected that it can get a lot of attention later on.

My current thinking is not to change the way the map and map data represents Hong Kong. One possible way to tilt the difficulty of taking HK is to bump up the fort level.

Since another map error was reported I have updated the map data again.

Here is the change:

Update 2022-01-28: I have uploaded a newer version of this map update, which now includes the following new fixes:

• The map data for the road leading west from Kendari has been added in hex 70,106 to match the map art.

The updated map is available at this website:

Is the Super Extended Map at that site. With the Data files?....GP

Hong Kong has gotten heavy attention and use in all my games...

The presence of rivers can make cd guns and mines ineffective depending how it is done.

During the Allied advance, right? I agree.

Also wanted to say thank you for your continued support of this game Andrew! Your continued updates make using any other maps obsolete at this point! Cheers!

No. Not yet.

[Andrew Brown]

I missed a map error previously reported by HansBolter. I have now added a fix for that as well. The fix is only in the map data.

Here is the change:

Update 2022-02-04: I have uploaded a newer version of this map update, which now includes the following new fixes:

• Phantom river hexsides removed from the E and SE sides of hex 62,55 (near Luangprabang).

Andrew:
I was messing around with ChemKid's Yamamoto map (the same holds for original map) and a week or so ago I noticed that in certain areas he had used a map graphic for shallow water that I found didn't match the WITP:AE Hotkey "1" in-game code OS. It was showing OD for deep.
So, I started looking around the map with Hex Terrain ON and noticed some other anomalies.
NOTE: This is the Standard version. I would assume the same issue is present on the Extended map, but haven't got it loaded to check.

First is the north coast of Australia in the Gulf of Carpentaria. I thought it seemed odd that Chemkid would overlook such a large area, but in checking Earth Bathymetry data maps he is correct and there is a rather large area of the gulf incorrectly designated OD when it should be OS.
Here is a pic with the area noted:


The second place is off the coast of Rangoon, Burma where two hexes are OD and should be OS per bathymetry data.


Lastly, in the narrows of the Strait of Malacca, two hexes are OD and should be OS per bathymetry data.


Hopefully this is the right place to post it. I haven't seen any other glaring depth issues.
Cheers!

I am not sure I fully understand your post Moltrey, but pressing the 1 key brings up the data file values (pwhex files) for each hex- nothing to do with map art done my ChemKid AFAIK. You are correct that the game stock map shows OD in those hexes but is coloured as OS. I am not sure what Earth Bathymetry data cutoff you are using for OS/OD, but I think the game map was using submarine depth values for shallow/deep and about 300 feet would be regarded as deep for a sub - but that is still continental shelf depth IRL.

So the map art colour should be fixed to match the data file or the data file should be changed to match the map art.

Based on what I see and just having loaded Andrew's latest standard map, the hexes in question are shallow based on the original map and Chemkid's, yet the pwhex is showing OD. So, yes, I think the data file should be changed to "OS" in those hexes. I just used the bathymetry to verify I wasn't getting the real data wrong.
Not sure about what metric the Devs used obviously, but these current in-game hexes in question would be outliers for sure, particularly in the Carpentaria Gulf and the Strait of Malacca where the RL depths are uniform. One could argue about the cutoff to deep water off Rangoon.

What is the date of the data/information that you are using for the Malacca Straits? The depth did change after the 2004 earthquake.

Some are newer, some are older. I looked at a bunch- to be honest I didn't see any real change in the shallow overall uniformity.
If someone can establish specifics, have at it. I just don't see evidence to rate the two deep hexes in the straights.
I would like to hear Andrew's opinion to see if he remembers any reasons why the data ended up as it did.

[RangerJoe]

I had read where the bottom of part of the Malacca Strait used to be much deeper but after the 2004 Banda Aceh earthquake the bottom lifted up. I shall have to see if I can find it again.

[Sardaukar]

There is this article about 2004 changes in Malacca Strait:

Apparently some parts used to be quite deep before.

This is where I had posted from before:

"Energy released

. (6 paragraphs down)
.
In February 2005, the Royal Navy vessel HMS Scott surveyed the seabed around the earthquake zone, which varies in depth between 1,000 and 5,000 m (550 and 2,730 fathoms; 3,300 and 16,400 ft). The survey, conducted using a high-resolution, multi-beam sonar system, revealed that the earthquake had made a considerable impact on the topography of the seabed. 1,500-metre-high (5,000 ft) thrust ridges created by previous geologic activity along the fault had collapsed, generating landslides several kilometres wide. One such landslide consisted of a single block of rock some 100 m (330 ft) high and 2 km (1.2 mi) long. The momentum of the water displaced by tectonic uplift had also dragged massive slabs of rock, each weighing millions of tonnes, as far as 10 km (6 mi) across the seabed. An oceanic trench several kilometres wide was exposed in the earthquake zone."

and

"Economic impact
.
. (6 paragraphs down)
.
Both the earthquake and the tsunami may have affected shipping in the Malacca Straits, which separate Malaysia and the Indonesian island of Sumatra, by changing the depth of the seabed and by disturbing navigational buoys and old shipwrecks. In one area of the Strait, water depths were previously up to 1,200 m (4,000 ft), and are now only 30 m (100 ft) in some areas, making shipping impossible and dangerous. These problems also made the delivery of relief aid more challenging. Compiling new navigational charts may take months or years. . . . "

So all this map data is from the 1940!

It should be for the game although some of the needed information may not exist while other information is not easily accessible.

Andrew,

This may already have been cited by others...

Nauru Island text is yellow in the stock map, which I understood to indicate an atoll. It appears to be small island.
