Find The Closest Match To Given Latitude / Longitude From Data Stored In 2 Columns?
Feb 2, 2014
I have 2 different sets of data: temperature data recorded at meteo-stations defined by latitude / longitude, and major world cities also defined by latitude / longitude.
After the user chooses the station's coordinates, temperature data is pulled out from the first data set; this works! However, I would like to be able to provide information about the closest city to the chosen meteo-station from the second data set.
I have list of address with zip code and Latitude and Longitude information. I am trying find a central locations, which will act as hub for rest of the address, by comparing distances from on locations to another.
Basically i need 2 things
1) How to identify the central locations 2) How to groups other locations around the central locations
I have more than 1000000 coordinates with heights to sort through. The aim is to be able to give a specific radius and check all coordinates within this radius if the slope is more than a maximum slope. If this is the case it need to put the value (in this case) 100 in a new column. The reason for this is we have a reasonable flat terrain but the entire area is filled with Anthills. I need to sort the data. Normal ground points (No Anthills) should be labelled/coded as 200 and anthills as 100. This will allow my program to know the difference between the ground and anthills. In the tab "Input Sheet" I have a small portion of co-ordinates starting from row 8 to row 53 (this will have to extend all the way down to the last row in excel). I need to copy each row starting with row 8 (C8:E8) and paste it in row 2 (C2:E2). Column H indicates if the points are forming an anthill and the code needs to change. I have my final answer in the tab "Final Answer" that I require for my program. Is there any way I can write a VBA code that will check all the point instead of doing it manually.
In my workbook I have multiple sheets but I'm attaching a very simple workbook to demonstrate what I'm trying to accomplish. In my "Lookup" tab/sheet. I want to have known Latitude and Longitude data that will exist in columns A&B. Columns C & D will have address numbers and Street Name. I would like my lookup formula to find the longitude and latitude data from my "lookup" sheet, when the matching address information is typed in, in my 2009 sheet. I have to keep the street numerics and street name separate on this worksheet as well. I believe I'll need two separate lookup formulas as I need these formulas to start in cell G4 & H4 in my "GeoCoding1" sheet. Is it possible to have four columns of data to be viewed in a lookup formula? I tried this formula in cell G4 (GeoCoding1 sheet)
I'm currently working on a project with data that includes columns for both latitude and longitude which I will need to convert from its current form into decimal degrees. The problem is that the coordinates are in the format DDDMMSS followed by a single letter indicating the direction, which means I have to first extract proper degree minute second format before I can do anything. Further complicating the problem is that each of the entries does not necessarily have all of the components I just described (eg some of the latitudes only have degrees and minutes but not seconds) and also if a longitude is less than 100 degrees, the third digit is not used in the data. There are over 2000 records so doing the conversion by hand just won't work and I've only got a few days to present this part of my project anyway.
I'm looking for a formula or series of formulas that will reliably convert something like 1083000W into -108.5000 when the last two zeros may or may not be there and the first digit may also be missing.
I currently have an excel file of around 40.000 records with their zip/postal codes accompanying addresses in countries all over Europe, I would like to convert these into latitude and longitude coordinates.
Some of the data I was given has latitudes and longitudes which are valuable to me but some of the information was entered incorrectly and the lat and long columns have only zeroes for some entries. I used some VBA to sort out all the ones that have zeroes in the lat and long columns because I noticed in a comments block some of them have the latitude and longitude placed in the comments instead of the designated spot.
An example of one of the comment cells is this: Search and Rescue 30NM S MARTHA'S VINEYARD 40-37.4N 070-43.3W MEDEVAC OF 35YOM E
As such the problem I am having is figuring out how to search through the cells for ones that have a lat and long in them since there is other information and numbers in the comment cell. Keep the cells that have latitudes and longitudes and get rid of the rest. The red highlighted information is what is valuable to me. Another problem is not all of the latitudes are in that format sadly as can be seen by this example cell:
SAR Unreported Vessel/ 42 01. N 067 25. W CLOSED AREA II/041527ZAUG06
If anyone has any insight/references into how I could go about doing this I would pretty much owe you my life since doing it manually would take ages for myself and my group on this project.
I am using Excel to calculate distances from latitude and longitude GPS positions. These positions have a format as follows:
S36 39.113 E174 25.945
These have been imported into a column, and using VBA I wish to separate latitude and longitude into two other columns. In both cases the minutes will eventually have to be express as decimals of the degrees. I don't mind if numerous columns are used as stages to get the final answer which is 36.234678 in one column and 174.15567 in the other.
Is there a formula that would allow me to run each of the 800 Lat/longs against the list of 7,000 and indicate how many on the original list have a match within 3 miles?
I was thinking a combination of countif with an array formula, but I can get the order of operations correct.
I'm using excel to try and sort by distance a list of wind farm locations from a location i put in.
This should be relitavely straight forward, however there are a few elements that make it more complicated.
I am getting a list of wind farm locations from the internet, the BWEA site. The latitude and longitude data copied over is in text. I'm using Excel '07 but it still requires me to butcher the numbers out of it with several columns of REPLACE formulas, it isn't elegant and may well be wrong.
The second and harder problem is that I have to first convert the latitude and lonitude values into OSGB grid references. So far i have found the OS maps excel converter, but it only converts one value at a time. I need something that will convert all of them at once (i don't want to go through and individually type in each distance).
After that it is possible to use basic trigonometry to find the distance between them and any grid reference i put in.
I have an excel workbook with 2 worksheets. One worksheet shows the MASTER LIST of COMPLETE Customer Names (e.g. ABB Supplies Incorporated). The other worksheet has information on customers but the customer names typed in are incomplete (e.g. ABC Supplies). I need a macro that would look do a comparison of the customer names in the 2nd worksheet to the Master List worksheet and pull the data (complete name, address, etc.) for those that would match (partial match since company name is 2nd worksheet is usually incomplete).
In the attached sheet, I am using !Staff times columns N and O to nominate a mid point break time relevant to the start,lunch break and finish times of a shift.
What I would like to do is match the result to the closest time from !Race Times Column D (highlighted green). So if for example the mid point of the shift is 10:37 (as in !Staff Times cell N23), it actually comes back with the !Race Times result of 10:35 which is the closest actual race.
Ideally I would like it to look both sides of the midpoint time until it came to the closest match, rather than always looking at an earlier time, or always a later time (eg the cell N79 has a value of 11:36, however the 2 race times are 11:35 and 11:40. Preference is it shows 11:35). If however the N79 result was 11:38 or 11:39, I would prefer it went to 11:40).
However if this is not possible then picking the next time in either direction will do.
I needed to know how to find the closest match to a reference number regardless of whether its larger or smaller. I did a search and found a post back in March that said to use the following:
I applied it to my application and it works, I just have no idea why. Can anyone explain this formula to me or tell me where I can find a good resource.
I have a database where I have groups defined. For example, Parent 0001 is called Bag1. It contains an apple, orange, grape, and a pear. Parent 0002 is called Bag2, containing an apple, orange, and a peach. So on and so on...
Below is an illustration of what I explained above:
I need a way to input items that are in the groups and find the groups have all of the items or the group with the best match. I need to know if the match is 100% or if it is only a partial match.
The bag might have 2 items or it could have 20 items and they can be in any order.
I have modified some code I found in these forums that once I enter a value in a cell I can have it find the closest match to that value and scroll down the list and paste that value as an offset. The code works perfectly, but my data will often contain the same values repeated and these aren't duplicates and I need to know how to loop the code to ensure it doesn't just find the first value but also the second (if the first is already populated) Code is:
Sub findclose() Dim rng As Range, Dn As Range, Mx As Single, oAd As String Dim num As Range
Set num = ActiveSheet.Range("B1")
[Code] .......
---- What I need to do is insert a loop of some sort that basically says IF my offset cell has a value then to find the next closest amount and continue the macro.
So if my list was:
700 50 500 600 500
And I wanted to find 499 then my list would look like:
700 50 500 499 600 500
BUT if I wanted to match off another amount of 501 it would keep the 499 it found and then find the 501 making the completed list look like:
700 50 500 499 600 500 501
Right now the amounts are being overidden as I don't know how to loop it...
I have a sheet of pump test results, placed in rows, where the test rig is set at a specific speeds and flow and it records pressure. At each stage of the test a number of snapshots will be taken (Usually between 3-5 at each stage), so I have 3-5 rows of very similar data. I only need to use the best row from the selection available, so I am hoping to find a formula or code (Don't care which) that can look at the results and select the row of readings where the speed AND the flow are closest to the targetted data.
For example: In cells G6:G8 I have flow result values 0.129, 0.151, 0.156 and in H6:H8 I have speed result values 72.536, 71.82, 72.13. These are actuals. In cell N6 I have the target speed (75) and in O6 I have flow target (0.15), but these could be moved anywhere to suit really. What I was hoping to do, but am struggling big time, was to just flag up the row of readings where these two values are closest to the targets by placing a check mark in column L:L which I have formatted in monotype sorts and would like to place a "4" (Which gives me a check mark) on the 'best' row. From that I can do more with some simple IF statements.
Is this feasible, or am I trying to do something beyond Excels capability, it is certainly beyond mine at the moment. I was looking at the check mark method, but that is not essential, so if anyone has any suggestions on an alternative means of identifying the best row of data, that might make it easier to do, then I am listening.
I have Excel 2010 & Window 7. I have 2 sheets of business names, some businesses in sheet 1 may be named slightly different in sheet 2 and not all businesses in sheet 1 are included in sheet 2. I would like to be able to find the closest match (from sheet 2) for the businesses on sheet 1 and return the closest matched business name.
problem is the data I receive does not always have the same time stamps
21:59:50 22:00:05 22:00:20
next time maybe
21:59:55 22:00:00 22:00:05
What I was doing originially in my userform was allowing form the user to input the starting time (without having to know the exact time) example 22:00. This works but the problem is when they enter the approximate end time 3:00. Without sorting the data how do I get the ending time to match the approximate time if the time doesn't exist in the data. I was using the Match function and the defined data range with 1 (i.e. Match(value, range, 0)). This works for the starting time but not the stop time since the data is not in ascending order.
I have the following table of stocks with corproate action types and dates with a ticker / identifier per stocA1:
Type B1: ID C1: Date
[Code]....
I am trying to find the NEXT Dividendcorporate action that is CLOSEST to the current date. I've done some google trawling and found a few formulae that seem to work only if the identifiers or dates are in a particular order. ALso having trouble using TWO criteria
I couldn't resolve the formula of Index-Match for getting the values that matches the following criteria
1) Match the "Category" of Table 1 to Table 2
2) Match the "value" of Table 1 to Table 2, if value is not present in Table 2 take the upper closest value.
Once the above conditions are met, Take the Result from Table 2
Table 1 is for Input and Table 2 is for Database.
Please note that Data in Table 2 should not be sorted in any way. I tried to use the -1 option of the Match function for upper closest value but it didn't work out.
Have a look at the file attached : IndexMatchUpperClosestValue_AlongwithExactMatch.xlsx
I am looking for a fourmla to return a value in a column next to the closest value. Yes, this would normally be a vlookup example however in my application the numbers will not match exact as such in an client lookup application. I need to find the closest value to the value compared in the range and return the value to the right of it.
I have made up a small table attached with comparing what vlookup gives me and what I am looking for.
The issue I have is that I want the result to return the CLOSEST match, not an exact or rounded up match. For example, is my "C18/C39" equation returns a value of 1.000039, I want it to match with "1" in the array and not with 1.25. The FALSE option will not work because exact matches will be very rare.
The values in the array are not whole numbers, so I don't believe a ROUNDUP type code will help.

I'm using vlookup to get a price for a unit of measure and it passes the value of the lesser not the greater. Is there anyway to get vlookup to pick the closest match as the greater value not the lesser one?
For example: 1000 units costs $8,000 4000 units cost $23,000 12000 units cost $68,000
If someone wants to buy 2500 units, I'd like the vlookup to pass the price based on 4000 units, but it passes 8,000 the value on 1000 units.
Can I use vlookup to give me the result of the greater unit not the lesser?
I am trying to find a closest match for a given value comparing to values in a chart. I got it to work..but it will only return a closest value that less than it. I need it to also look "up", and return a value higher than it if it is closer. I have attached the worksheet. The vlookup part is for choosing which row to use, based on the value in B1. The column index portion of the vlookup is where the trouble lies....I am comparing the value found it B2 to chose the column...and that column should be the closest value...but like I said before, it will only return a lower value. The formula is in cell B11 (Correction Factor). it SHOULD return 1.26....instead, its giving me 1.18. (200 is closer to 192 than 175 is)
