<p style="margin-left: 0.5in;"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">Dear users<br>
<br>
i have the following SQL sentence that work's fine with postgreSQL 8.0.7,
win32, and PostGIS<br>
<br>
SELECT DISTINCT(<span><span name="st">intersection</span></span>((SELECT
collect(the_geom) FROM ejes_13<br>
WHERE nombre = 'BALMACEDA' AND nom_com1 = 'PUENTE ALTO'),(SELECT<br>
collect(the_geom) FROM ejes_13 WHERE nombre = 'EYZAGUIRRE' AND<br>
nom_com1 = 'PUENTE ALTO'))) FROM ejes_13 WHERE (nombre = 'BALMACEDA'<br>
OR nombre = 'EYZAGUIRRE') AND nom_com1 = 'PUENTE ALTO';<br>
<br>
this sql sentence give the point for the intersection of two streets, where
"ejes_13" is the table with the street geometry, "nombre"
is the field with the name of the street, and "nom_com1" is the field
with the town name. <br>
<br>
when i run this sentence in postgreSQL 8.1.3, win32, and PostGIS, the data
engine gives me the following error.<br>
<br>
ERROR: GEOS Intersection() threw an error!<br>
<br>
does somebody any ideas about this.....<br>
<br>
Regards<br>
