Hi List
I am playing around with pgr_analyzegraph, its told me I have
Dead ends: 7
Potential gaps found near dead ends: 3
In a network of 7000 vertexs finding Potential gaps in a map that I did not generate is going to be hard, is there anyway of get pgroute to actually tell me were these problems are?
Those are geometry gaps, so maybe you can ask on postGIS

I assume you mean something like a multi line string with a hole in it !

What I mean is that maybe you have like the example on the docuemntation
1, 2, 1, 1, 130, 100, 0.5, 3.5, 1.999999999999,3.5),
the
1.999999999999
is almost 2, but its not a 2, so if another segment start on (2, 3.5) then
unless if you don’t use a tolerance to assign source and target values both vertices will have a different id
if you assign a tolerance then both vertices will have the same id, but note that for one id there would be two different values on the geometry, if you also want to “fix” the geometry then that is done with PostGIS
