I have a road network and want to test connectivity between the features. I am having trouble with two specific features, the rest of the dataset is functioning just fine.
When I get those 2 links' start & end locations using ST_StartPoint and ST_EndPoint, the result is that they are slightly different. However, when I convert the result to text by wrapping it like so:
ST_AsText(ST_StartPoint(geom)) and ST_AsText(ST_EndPoint(geom))
then the results are exactly the same. Is it possible they are actually off by a tiny amount like .000000001 and the ST_AsText loses a decimal point?
