# Invalid shapefile geometry

From Wikiagro.com

If you're trying to import layers into **360** and you find issues, it may be an invalid shapefile geometry error. These are some possible causes:

## Topologically invalid geometries

If your polygon lines cross over themselves, the geometry is not valid.

To solve this, you must edit polygon geometry and avoid overlapping.

## Different geographic system

**360** uses WGS84 only. If you are trying to import shapefiles in a different projection system and do not have your projection file (.prj extension), the system will not be aware of your original projection system and the resulting geometry will not be shown correctly in your map.

To avoid this, make sure you have your .prj file when importing
