check if coordinates are within certain polygon

[samahiji]

Hi,

I have two tables:

Table 1 contains all X Y coordinates 

Table 2 contains the polygon shape file coordinates,

I want to check which coordinates are within the polygon.

I used the sample data provided by @p45cal. Maybe you want this.

@samahiji You can leave your e-mail and i'll reply you with source code(about today or tomorrow).

Hello there,

I'm working on a similar conundrum. Do you still have the code to work on this?

[p45cal]

Yes, let's have some tables from you. Preferably in an app (say Excel as a workbook).

I've been working on polygons like this and have (I think) been successful (purely in Power Query) but I won't post my offering (because it's a mess, currently) until I have a good idea of how your data arrives and how you want it to show at the end.

Hi @p45cal ,

That's exactly what I want. My data is huge, attached is a sample of it. I have two tables, the polygon X&Y is in sheet "Polygon", the data point is in another sheet "Points". A new column "IN/OUT" in sheet "Points" is calculated with 0 if out, 1 if in.

unfortunately, I can't upload the file, here is a snapshot.

1. Upload it to a file sharing site or onedrive, dropbox, box.com, googledrive etc. there are loads of them, and drop the link to it here.

If it contains sensitive info delete all unnecessary sheets and just supply two tables on two sheets. Pictures aren't much use.

2. Does it have to be Power Query? Could it be a custom user-defined function in vba (a macro)?

Hi @samahiji,
Thank you for reaching out to the Microsoft Fabric Community forum.

Here I have taken 2 sample datasets as per information and did the steps for your understanding, but it will be better for us to perform steps accurately and we can guide you accordingly if you can provide us the Data if possible.
This process can be done in many ways, where I followed DAX queries to perform.

For your Idea, I’ve attached the PBIX file with the implemented solution. Please review it and let us know is there any further questions.

@samahiji Sorry, having trouble following, can you post sample data as text and expected output?

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.
