No problem Tom.
I think the best way to get a perfect map (almost) is a combination of the the West Survey map notifications, the map for the Topographic map for HSCA
from Drommer with exclusive height notes from 1978 and a current measurement of all important parts of DP to create a CAD Model of
the 1963 Dealey Plaza with all it's special features as it has in 1963. Raise it into a 3D model as best as you can.... and you have a perfect measure tool.
I know just two persons whom had done it and published it: Dale K. Myers and the guy from " Death in Dealey Plaza" who had done it with a special camera
which was roughly 30-40 cm correct as it was said in this documentary.
None of this 3D models were ever open published.
Both of this models are promoting the theory that Oswald was a Loner.
I've done it in parts myself. I did id for free and not payed. I have an open mind and found in that some parts that for instance Myers model
does have mistakes in it. It's not just the model, it's also the speed of the cameras. Means Frames per second.
The Towner camera for example runs not as Myers published. Even Gary Mack told me this. Apart from Chris Davidson who owned the
the same camera.
If i get ever be free of the circle of "payed for bill" and found some kind of promoter for this work from an unbiased person, i can do some
great favours for the community to measure DP myself. I have the knowledge and abilty. I have CAD and and a proper 3D program.
I have the knowledge to measure 3D myelf with the required tools.
And i'am willing to open it, publish for free for all to proof it by their own.
Following this thread (or others) you'll learn that i've a profound knowledge of the photographic evidence as well.
In case you doubt it: ask any person of your mind about me and what i said.
best to you

This kind of model can open new gates in this case.
One thing I could never get Dale Myers to admit to was if his map was the original 1978 HSCA map or the 1981 revision which was made for me.
I assume you know that the copy I sent you was printed out by Drommer and Associates from the 1981 revision survey and corrects the 1978 survey done for the HSCA.
They won't say what the differences are but the difference I pointed out was the distance from the middle of Main Street to the face of the TSBD.
I also uploaded for you scans of measurements made in Dealey Plaza.
I think we need to show both the original 1963 conditions and the changes by the time of the acoustics tests in 1978. Anyone studying the acoustics needs to take into account the changes from 1963 to 1978.
The changing size of the trees is not going to have a significant impact on the echo matching. But the moving of lampposts or signs will.
Analyzing the test shots can also be used backwards to confirm the location of objects in 1978 as well as the fixed objects since 1963. Unfortunately the HSCA will not release the information and BBN considers their role over.
Analyzing the echo paths identified by Weiss and Aschkenazy can help a little. One major failing of the JFK Records Act is that they did not require BBN and W&A to turn over all their research material to the National Archives.
I hate to be Xenophobic, but it would be much better to mark distances in feet and tenths of a foot rather than metric. The HSCA map is scaled that way.
When it comes to the computer map we have to compromise. Because I wrote the first computer map on a Commodore 64 the width of the screen was only 640 pixels so I decided on a scale of 1 pixel equals a half foot.
When someone scanned in the map for me the scale was lost in order to create smooth lines. That's ok with me, but it makes it impossible to draw on or add to scale.
I have produced some copies with reasonable scale, but some are very hard to view on a computer screen. But most computer screens can now handle up to 2000 pixels wide. We need to display at least 350 feet wide to show Main Street to the floor layout inside the TSBD, so I would recommend showing 400 feet for the width. On a screen size of 2000 pixels that would give us 5 pixels per foot. The error margin of .2' instead of .1' is acceptable.
5 pixels per foot would still show most of the details even if the consensus screen width is less than 2000 pixels.
Right now my screen size is 1920 x 1080 which would display 384 feet wide. My old screen size was only 1280 x 720 which would only display 256 feet wide, not enough to show Main Street to the TSBD.
384 feet also allows us to show the location of photographers on the other side of Main.
I realize that file size is also a problem for some people. Most of the time I keep the map in black and white only and use a standard GIF 89A format to compress the map as small as possible.
I think we still can use compression but it could be another standard like JPG or PNG as long as it is a well known Internet standard file type which displays in ALL browsers correctly. I sometimes have to test my Web pages in 8 or 9 different browser programs to look for incompatibility. I would balk at using a format which requires users to buy a $1000 CAD program to view them.
Some might want it in color so that the basic plat is in black and white and then some details can be show in color. Some file formats allow you to show objects as ghosts. This would be good to include the changes made by 1978.
Some formats allow you to click on an object and blow it up to show the detail. This would be handy to examine shooter locations like the TBBD.
On a personal note I hope that you will keep me posted on your progress and e-mail whatever working files you have created. I may be able to spot a minor error before you include it in the final production.
I also think we should make this open to everyone to add on their own wish lists. Maybe someone wants to see the storm drains. Maybe someone wants to see views from different shooter locations.
Maybe someone wants to check side views to see what shots are possible. Maybe someone wants to see all the spectators and click on one to bring up that person's testimony. Etc.
Perhaps the most controversial would be whether to show the position of the limousine and at which frames. At a minimum I think we have to show the CORRECT position of the limo at frame Z-313.
