I am trying to build a statewide road network for analysis with pgRouting. I ran pgr_createTopology, and it reported OK.
Next I tried to run pgr_analyzeGraph, and got an error.
Here is the command I input:
And here is the error message:
NOTICE: Analyzing for ring geometries. Please wait...
ERROR: isring() should only be called on a LINE
CONTEXT: SQL statement "SELECT count(*) FROM public.ng_roads
WHERE true AND (true) and st_isRing(st_linemerge(geom))"
PL/pgSQL function pgr_analyzegraph(text,double precision,text,text,text,text,text) line 309 at EXECUTE statement
-What should I do about this? Can I still perform pgRouting analysis with these roads?
