G'day all,
I have a roads shapefile which I imported in PostGIS, planning to
merge several different countries data eventually. It is producing a
layer on the map, and labels etc.
However, the data isn't all good - in fact, about 10% is bad :
es=# select IsValid(the_geom), count(gid) from gis_roads group by
IsValid(the_geom);
isvalid | count
----------+-------
| 4128
t | 39670
(2 rows)
My question then is :
should I ?
a) leave it - it won't do any harm, but probably won't be rendered,
b) remove it - it may be incorrectly rendered, or waste processor time
on data that is unuseable,
c) fix it by hand (lazy git!)
d) fix it automatically, using super program I wasn't aware of.
(called?)
actually, I don't have the time or budget for option c, and I suspect
option d does not exist!
cheers
Ben
