Hi all,<br>
<br>
I have found what appears to be a problem in one of the<br>
routing_core_smart functions.<br>
<br>
In the function locate_point_as_geometry there are two lines which<br>
call the function geometryfromtext.<br>
<br>
These functions are called when line_substring returns a point.<br>
<br>
In the geometryfromtext function calls, there is no second
argument<br>
for the srid. This produces a geometry with a
“-1” for the srid.<br>
<br>
When I use shootingstar_smart in my script, MapServer fails on<br>
trying to work with two geometries with different srids.<br>
<br>
Adding the second argument to the geometryfromtext function fixed<br>
this problem. The only geometry with the “-1”
srid was the one<br>
created by these function calls.<br>
<br>
I hope this helps someone.<br>
<br>
Worth Lutz<br>
