<p class="MsoNormal" style="margin:0in 0in 0.0001pt;font-size:11pt;font-family:Calibri,sans-serif">I hope this mail meets you well. My name is Jeremiah, a
master’s student in Universidade NOVA de Lisboa, Information Management
School(IMS) currently enrolled in Geospatial Technologies. I came across
your guidance on PGrouting for barriers, which has led me to seek your
assistance and tutelage on how to solve this kind of problem for my project. </p>

<p class="MsoNormal" style="margin:0in 0in 0.0001pt;font-size:11pt;font-family:Calibri,sans-serif">We are trying to find a way on how we can generate an SQL
code to make our routing network recognize barriers based on the fact that we
have uploaded the network with source, target, cost , reverse cost, coordinate
field or column. We are hoping you can give us ideas on the algorithm that can
help us make the network recognize barriers. Thank you Sir for your time and
anticipated response.</p>
