Hi, I have a airtable with locations with their Latitude and Longitude. I want to filter a Data Viewer List of the locations based on me for example saying show locations within 1 mile, 2 miles etc of my current location. And also the same filter but i want to set the location and not use my current location. Thanks in advance as this community has really helped and I appreciate it. ---

To do the filtering you need first convert the `within 1 mile` to actual coordinates and then just check each record if within those computed coordinates or not. Ideally, you want to assume your location (or the supplied location) is the center of a circle and produce and array or coordinates of multiple points on the circumference. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/3/a/3a67f0c9ba379dd9df27fea553f242804b01aaea.png) This could be be simplifies by assuming a **square** instead of a **circle**. This way you have **two** coordinates to worry about (top-left, bottom-right) and now you can start your loop through the rows of the DVL testing if the location is between these two points. ---

You can search the forums for the Haversine formula. If you have online access from your app, it’s easiest to use the formula in a Google Sheet. If not, you can code it using blocks and have Thunkable calculate the distance between two lat/lon pairs. ---

Xano would be a great use case for something like this! You could save all your points in the backend and use their geoquery capabilities to quickly return only the relevant results! ---
