How This Works
A bounding box is the smallest lat/lon-aligned rectangle that fully contains a set of points — useful for setting a map’s initial zoom/extent, defining a rough search area for a dataset, or simply seeing how spread out a set of locations is. This tool finds the minimum and maximum latitude and longitude across all your points and draws the resulting rectangle.
FAQ
Is my data uploaded anywhere?
