This is a lightweight tool for enriching a CSV with H3 tile IDs, at a user specified resolution, with or without each row's original coordinates.
Your original CSV must have columns labeled lat and lon for this tool to recognize the coordinate data. (I'll make that more forgiving in an forthcoming version...)
Cluster with Aggregate Functions: You can also use this tool to aggregate your records. Click the "Aggregate" button to apply summarization functions to numeric columns (like sum, mean, median, or count), generating statistics for each tile at the resolution you desire.
A Tool for Masking Sensitive Data: All data manipulated by this tool doesn't leave your machine. It is entirely private, making this tool perfect for rolling-up sensitive data (like movement data or household statistics) up to clustered H3 tile regions. Keep an eye on on the "Minimum points in a cell" figure at the bottom of the page to ensure you're at a resolution level adequate to mask an individual record.
Remove Stray Records: Sometimes your input data might have an outlier record you don't want in your final product. Click the red point you'd like to remove, then hit the "Remove Point" button.
