I digitized a cyclone track on ArcGIS as a polyline. Then i created a buffer of 100 km using the buffer tool. My parameters when using the buffer are:
- Distance- Linear Unit of 100km
- Side Type- Full
- End Type- Round
- Method- Planar
- Dissolve Type- None
- Coordinate System- Projected (Fiji Map Grid 1976)
Then i wanted to upload it on ArcGIS online. I used the Add layer from file tool. The buffers werent showing so i had to play around with the visibility range of each feature. But when the buffers finally appear, it has a line at the very bottom as shown on the picture below marked blue.
I dont know where that came from.
