All,
This is probably a generic postgres question, but . .
I’m trying to generate a line segment data table from a (parcel) polygon
dataset. I need to bind the polygon (ParcelId) to each segment as well as
maintain the sequence of the line strings that make up the source polygon, so I
need to
a segment
id for each polygon.
(to adapt in case of multipg):
with tmp as (
select 1::int as id, 'POLYGON((0 0, 1 0, 1 1, 0 0))'::geometry(polygon) as
geom
), tmp1 as (
SELECT id, st_dumppoints(geom) as d
FROM tmp
), tmp2 as (
select t1.id<http://t1.id/>, (t1.d).path[2
All,
I tried DXF (although there were some settings I didn’t try) and that didn’t
seem to work, the arcs came in, but no attribute (extended) data applied to any
of the features. Even GeoJSON doesn’t seem to support circles/arcs (right)?
Am I going to need to write my own importer for CSV, or?
(assoc -1 (entget (entlast) (ade_odaddrecord newf "CSEGMENTS")
(ade_odsetfield newf "CSEGMENTS" "row_number" 0 1) (ade_odsetfield newf

I’m trying to remove all duplicated parcel edges from an exploded parcel
dataset. I have a set of 2 point line segments and I’ve been able to find the
geom duplicates ok witha window partition, but the number was really low. Upon
examining the data more closely, I figured out that the majoirty
e docs: "Returns true if the given geometries represent the same
geometry. Directionality is ignored."
Best,

JK,
I don’t know what you end goal is with this (completely) but I’ve been working
on something similar. And I founf that you needed to isolate the circular
strings into separate features, in other words, “explode” the parcel edges into
separate features, and work the process against both feat

I think Baalbek is too large (too many triangles) and therefore possibly leads
