Question about the grid system

[oneway]

I have a quick and easy question concerning the grid system...

Taking for instance map grid square at 10.10..and consistent with the overlay grid found in the editor...

Does grid 10.10 start at the lower left corner of 10.00 / 10.00  or does it start at the lower left corner of 10.04 / 10.04...ie the upper left of 10.10 / 10.10

Everything else in terms of maps, grids and coordinate systems seems left to right centric so I am guessing its the former not the later...

However the text in each grid is neither in the upper right or the lower left...so its kind of hard to figure out what the grid designator is actually demarcating...

Would a picture help?

A picture would help but I think I know what you are saying.

The 10.04 / 10.04 tile square in the TE is in the lower left corner of the center square on the clipboard map making the lower left of 10.04 / 10.04 the absolute lower left of the center square.  The actual number of the center square on the clipboard map depends on the size of the terrain and can be anything the terrain designer wants to make it since the clipboard map is just a bitmap.  The only thing the designer can not do is change the location of the grids – well he can but the bar-dars will not line up with the new grid.

Thanks for the reply and here is the picture so I can nail this down...

And yes I am fully up to speed that "map center is 10.24 x 10.24...

The reason I need this that I have a program that crunches image files and turns them into actionable maps for use in event planning...I am endeavoring to create a substrate grid that is consistent with the model of grid system as defined by AH...

When my program loads up an underlying image it is either 2048 or 1024...indexing the image with the coordinate system is crucial...

Here is an image more clearly describing my question:

And   and thanks for your response...

I wouldn't need to hassle with this if I had the necessary oba files to feed into my program..but for now I have to come up with a work around and create a snap grid system that lets me duplicate what already exists in simple text files...thus the user of the program will be unnecessarily forced into to dragging an dropping map assets on to a grid...I want to make sure my snap system is accurate...and its grid index Zero as defined by Grid Square 10.10 lower left corner is correct...and yes I am aware that actual Grid Zero is in 10.24x2

[oneway]

To give you an idea of what I am working on I offer the following image...

Fortunately I was given the oba for northsea...upon leveraging that, the planning program is capable of generating interactive planning maps that let the user decide what and what not to show...this image for example shows  shore battery traverse and coverage overlaps..in this case shore battery coverage for 91 and 92 was made visible...it also demonstrates the 'melding' of warning ranges, radar ranges....ship start grids and active bases...

This image was called up for an analysis requested by command on the range and overlaps of the battery's at those two fields...

Without oba files I need to definitively define the grid system at its finest granularity....users will be forced to consume PLN and FLD files...thats better than nothing...then the user can drag fields into the grid and they will at least lock up in the appropriate grid square - sub grid mini square...

Of course without oba rotational data on shore battery we cannot plot traverse angles and over laps...but at this point I just need to make sure my grid indexing algorithm is consistent with terrain editor output...

I want to make sure my object snap is correct....

Thus my question...




The end result of this work will be a free product for the community available to any event commander who wishes to leverage the tool...the whole idea of this is to give all planners a tool that eases their work load..thus drawing in more people willing to assume command...and subsequently enourages 'day' players because their commanders are armed and proficient with the information necessary for team success...

Its about operational effectiveness and execution...its about elevating the experience...

This is an extremely simple question to answer...

I would assume the Terrain CM's could answer it directly and poignantly..

They have commented on other threads in this forum since I posted this question...so I know they are here...

Is their a problem with my question?

Is the question unclear?

Let me restate the question in a yes or no format...so its crystal clear...

Does in game Grid Square 10.10 lower left coincide with terrain editor 10.10 lower left......

This is not rocket science...it is just a simple question....

Yes or No ????

[Easyscor]

This CM doesn't know.

I'd have to go look, and then try to figure it out, same as you could, but it's not something I need to know. I can't speak to anyone else knowing it, or needing to know it.

[ghostdancer]

I would take there silence as a simple I don't know. Since I am with Easyscor on this one. Knowing if in game Grid Square 10.10 lower left coincide with terrain editor 10.10 lower left has had no impact or should say has not impeded creation of terrain for me. So I have never even considered the question. I also would have to research just like you.

Would probably be quicker to fire off a question to HTC asking for the answer to this considering they are the ones who wrote the code / created the grid system.

No.  The game Grid Square 10.10 lower left coincides with the center of the terrain editor’s 10.00 / 10.00 grid tile.

In the TE the lower left, 0.00/0.00, is in the center of the terrain tile.  If I wanted to put land in the lower left corner of tile 0.00/0.00, I would have to go all the way into the upper right corner of the TE to do it.  The TE boundaries are at the tile centers and not the tile edges.  So the game Grid Square 10.10 runs from the center of the TE’s 10.00/10.00 (game grid’s lower left) to the center of 11.00/11.00 (game grid’s upper right).

To anticipate you next question, the center of 11.00/11.00 is not included in the game grid 10.10.

Now to be fair, this is to the best of my knowlege.  You would have to ask the guy resposible for running the bar-dar to know at which point he moves the bar to the next tile.

Fascinating....

Not at all what I would have expected...

If that (bold text in quote) is true, then you could put a base in that lower left square such as my image above depicts and that base would be in 4 Grid squares simultaneously? 9.9, 9.10, 10.9 and 10.10 ???

I recall reading somewhere that the way the grid system was set up in TE, it prevents the user from doing just that sort of thing...

That doesn't seem right...perhaps I misunderstood what you were saying.

[oneway]

I found the answer I was looking for....

The TE grid exactly matches the in game grid. That is to say that the lower left corner of the 10.00 10.00 TE grid square is the lower left corner of the 10 10 in game 25 mile grid square...
