One Mapper

Single Variable Mapping

Visualize data by location and split into four value ranges by uploading data or clicking on the map (Tutorial). If you need to clear the map, click this button.

Where do you want to map?

Select your basemap using the small box in the upper right of the map. Navigate with the dropdown menu or by click and zoom. On data upload, map will automatically zoom to your points.

What do you want to map?

Existing dataset? Upload using the link

Your csv should have three columns: Lat, Lon, and Value. Download a template dataset.

After loading in points, visualize by groups!

Try out some different color ramps, fill, and point size.

The single color options do not show the four groups. Use these options if you want to show placement, but not value. The scalar button provides proportional points based on value.

No fill Total fill

Smaller point Larger point
