Other details

  • This is in the Philippines and I'm using WGS_1984_UTM_Zone_51N
  • The buffer is 1km long so it must be the map layer that is wrong
  • I tried the Geodesic method instead of Planar but still got the same problem
  • Posted on r/gis and r/arcgis and am still lost on what I'm doing wrong so I posted here

Is the extent perhaps wrong?

There is a problem with the spatial reference of your layer. The extent seems to correspond to geographic coordinates in degrees, but the crs assigned to the layer is a projected one - UTM Zone 51 in meters.

You could try the following and see if it resolves the issue:

  • Set your layer crs to GCS_WGS_1984 (epsg 4326) with Define Projection tool
  • Project your layer to WGS_1984_UTM_Zone_51N with the Project tool.
  • Check if the layer aligns with data from other sources or a basemap. If it does, then buffer your layer.

I would check the other layers as well, from what I see, they may have the same problem as your point layer.

This sort of issue can happen when we confuse the Define Projection and Project functions, and when a layer crs is changed directly in the feature class properties instead of using the Project tool.

  • Thank you. I'll do those when I encounter the same problem again. For now, I just redownloaded and redid all my data. :)
