[Solved] Coordinate Data

**bsjordan** · 08-06-2011, 12:22 PM

Hi, All

These are likely simple questions, but I've been banging my head for hours with tutorials with no joy.

I have a csv file containing a Z coordinate only. I need to add x and y, whereas cell A1 is 1,1,"Z value", cell B1 is 1,2,"Z value", cell A2 is 2,1,"Z value". I have 480 rows and 640 columns of data, so the last cell should be 480,640,"Z value".

I've attached a screenshot showing in A1 the desired result. I appreciate any help.

EDIT

To clarify, the X and Y coordinates will simply be the cell number with a comma separator. Hope that helps. Oh, and this would be my first post, so if I didn't ask properly, please let me know. Thanks.

open csv with excel put z value in sheet 2 !a1
then in sheet 1 a1 put
=COLUMN()&","&ROW()&","&Sheet2!$A$1 drag across 640 then down to row 480
once done copy all of sheet 1 and paste back straight away as paste /special/ values to remove formula
then delete value in sheet2 a1 and save as csv

**bsjordan** · 08-06-2011, 02:31 PM

Thanks, Martin. Will try this now.

**bsjordan** · 08-06-2011, 02:37 PM

Martin, was the "!" in your first statement "...sheet 2 !a1" purposeful or incidental?

**martindwilson** · 08-06-2011, 02:39 PM

thats just how formulas refer to sheet2 just put the z value in cell a1 of sheet2
like this i've just filled it out a small bit

**bsjordan** · 08-06-2011, 02:53 PM

Okay, great! That worked! I'll have to study the formula to understand the function, but it seems simplistic enough.

The last thing I need is to convert this into a single column of data and assign a "point number". I figure this is the "Count" function, but I don't know how to append Column B to the bottom of A, C to B, etc.

**bsjordan** · 08-06-2011, 02:58 PM

Uh-oh, wait a sec. I just noticed that the Z value from Sheet 2 is the "only" value. I have unique Z values for each cell.

**bsjordan** · 08-06-2011, 03:04 PM

Here's a snapshot of the full file. sorry for the misunderstanding.

**martindwilson** · 08-06-2011, 03:06 PM

i assume it starts at a1 and all 640X40 cells are filled with z data
use =COLUMN()&","&ROW()&","&Sheet2!A1
then do it like this

**bsjordan** · 08-06-2011, 03:18 PM

Perfect. So removing the $ sign was the key there, right? Thanks for this.

Do you have any ideas about putting them into a single column format with an assigned number?

**martindwilson** · 08-06-2011, 03:32 PM

yep but what do you mean,you want them goimg straight down,all of row 1 then row 2 after and so on?

**bsjordan** · 08-06-2011, 03:39 PM

Basically, I need a file that looks similar to the attached. With your help, we've created the xyz components. Now I need to add a point number and have all of the data arranged in 4 columns of PT#, X, Y, Z. Does this make sense? I don't feel like I'm being as clear as I could.

**martindwilson** · 08-06-2011, 04:10 PM

how did x/y change to non integers? since the are coordinates 1,1 2,1 etc
also should the order be down then across or across then down

**bsjordan** · 08-06-2011, 04:25 PM

The example I attached was a different coordinate system (State Plane Coordinate System, to be exact). I maybe should have used a different example.

This is what the first few points would ideally look like, starting with A1:

PT# X Y Z
1 1 1 58.51762
2 1 2 57.85823
3 1 3 57.78638

That's the end result I want, but if I can get this:

1,1,1,58.51762 in A1
2,1,2,57.85823 in A2
etc.

That would be sufficient. I can edit out the commas and create the spacing I need afterwards.

At the end of column A, I need to append column B starting with B1. At the end of B, start with C, and so on. So, we could have a single column (A) with the 4 values (1,1,1,58.51762, for example) in it.

**bsjordan** · 08-06-2011, 05:25 PM

If it makes any easier, I don't necessarily need the point number added. All I need for a certainty is to have x,y, and z. It can be comma delimited in a single column A, or three separate columns A,B, and C.

**shg** · 08-06-2011, 05:41 PM

Maybe I'm entirely missing what you're trying to do, but it you have this on sheet1

...and want this on sheet2,

Then on sheet2!A1 and copy across and down,

=ROW() & "," & COLUMN() & "," & Sheet1!A1

**bsjordan** · 08-06-2011, 06:01 PM

Thanks for the reply, shg. We already have that accomplished. What I need is to convert this:

--A--- --B--- --C--- --D---
1 1,1,47 1,2,56 1,3,69 1,4,68
2 2,1,15 2,2,31 2,3,90 2,4,55
3 3,1,93 3,2,68 3,3,44 3,4,23
4 4,1,36 4,2,75 4,3,44 4,4,85

to this:
1 1,1,47
2 2,1,15
3 3,1,93
4 4,1,36
5 1,2,56
6 2,2,31
7 3,2,68
8 4,2,75
9 1,3,69
...and so on

Basically, append B to A, C to B, D to C, etc...

Can you help with this?

In F2 and down,

=INDEX($A$1:$C$4, MOD(E2-1, ROWS($A$1:$C$4)) + 1, INT((E2-1) / ROWS($A$1:$C$4)) + 1)

**bsjordan** · 08-06-2011, 06:22 PM

Looking at this, I think this is limited to the first 4 values in columns A,B, and C. Am I right? If so, I actually need to cover everything to cell XP480. Would it look like this?

=INDEX($A$1:$XP$480, MOD(E2-1, ROWS($A$1:$XP$480)) + 1, INT((E2-1) / ROWS($A$1:$XP$480)) + 1)

**bsjordan** · 08-06-2011, 06:24 PM

I tried it. It doesn't seem to work.

**shg** · 08-06-2011, 06:24 PM

Yes.

And if you name the data tbl, you can simplify the formula to

=INDEX(tbl, MOD(E2-1, ROWS(tbl)) + 1, INT((E2-1) / ROWS(tbl)) + 1)

**shg** · 08-06-2011, 06:25 PM

It does. Try again.

**bsjordan** · 08-06-2011, 06:26 PM

I know it's basic, but how do I enter the formula? And how would I rename the data to tbl? Would I just save the file out to that name?

**bsjordan** · 08-06-2011, 06:33 PM

Also, I don't really need to copy the data. That is, I don't need to keep columns B,C, and D after appending them to A. Since I have a 640x480 cell, I have to put the new column out in the "XT" column range. So, I think the formula may need to look like this:

=INDEX($A$1:$XP$480, MOD(XT2-1, ROWS($A$1:$XP$480)) + 1, INT((XT2-1) / ROWS($A$1:$XP$480)) + 1)

Does this look right?

**bsjordan** · 08-06-2011, 06:43 PM

Ok, so when I hit F2, enter the command (overwriting the coordinate present in A1, I get a box in the XT2 cell. I drag it down and release, but I get nothing. Obviously, I'm missing something.

**bsjordan** · 08-06-2011, 06:48 PM

I've tried to rename the file and the worksheet to "tbl", and use the second formula you provided. Again, I see a box, but the data doesn't appear when I drag it down. Any thoughts?

**martindwilson** · 08-06-2011, 06:54 PM

1,1,45.17
2,1,30.2
3,1,80.91
4,1,57.8
5,1,69.28
6,1,51.65
7,1,89.32
8,1,34.31
9,1,31.36
10,1,6.61
11,1,23.01
12,1,82.6
13,1,9.66
is easily doable in word
copy the lot then past special unformatted text into word
find replace ^t with ^p
then copy paste back to excel
then use text to columns using comma , as delimiter to separate

**bsjordan** · 08-06-2011, 06:57 PM

I've attached a screenshot of what I'm looking at. I'm not sure what to do with the box. I've tried grabbing the corner and clicking on the center of the box, but neither works as needed.

**bsjordan** · 08-06-2011, 07:06 PM

"find replace ^t with ^p"
I'm not sure I understand this. I just copied and pasted into Word, but, because of the size of the file, it's still working to display it.

**bsjordan** · 08-06-2011, 07:14 PM

Martin,

It appears that the file is going to be too big for Word to handle in a reasonable way. Too much data. It's still crunching.

I'm willing to try to work with the formula that shg has provided, but I can't get it to work properly.

**bsjordan** · 08-06-2011, 07:16 PM

This is what I'm getting in Word.

**martindwilson** · 08-06-2011, 08:20 PM

i just did it and athough it took just under 2 mins to replace in word, i now have 307200 rows in excel did you paste special unformatted text into word?

**bsjordan** · 08-06-2011, 08:37 PM

Thanks, Martin. It was the "Paste Special" command that I should have used. Unfortunately, I'm now not sure how to get things formatted properly in Word. I understand what you are trying to do, and I know that once it's formatted, i can import into Excel with no problem. What is the command I need to do for Word to format properly?

**shg** · 08-06-2011, 08:41 PM

I think Martin's suggestion is excellent.

Example of the formula I posted attached.

**martindwilson** · 08-06-2011, 08:41 PM

once the find replace is done just copy all paste back into excel
then select th column and use text to columns to splt

**bsjordan** · 08-06-2011, 08:47 PM

I'm beginning a little inadequate!

I've attached what I'm looking at in Word. Not sure what I should be "finding and replacing".

**bsjordan** · 08-06-2011, 08:53 PM

again, thanks for you help, guys.

**martindwilson** · 08-06-2011, 08:53 PM

find ^t (which is tab),replace with ^p (which is paragraph mark) this is how it looks (yours will be slightly different as you have excel 2010)

**bsjordan** · 08-06-2011, 09:04 PM

Success! I'm going to add a column of numbers, and I think we've got it licked. Thank you both for your patience.
