I am using postgres with postgis for spatial data and ArcGIS for visualisation. I am really confused regarding what units the st buffer function uses because when I insert just the value 1 as measurement to be buffered around a line, the line becomes very wide.
Then when I enter a value like 0.00001 the line width would be small. Is there a way where I change or set the units of the value?
How can I have more control on the value I want the line to be wide? Since I am building roads with various width values.
