hi all,<br>
<br>
<br>
<br>
i'd like to implement something to do partial edge traversal at the
end of each route so my function isn't limited to all or nothing
edges. I saw the implementation of starting from the nearest edge
point <a
href="http://lists.osgeo.org/pipermail/pgrouting-users/2012-January/000927.html">here</a>
(as opposed to the nearest node and i will implement that, thanks
steve). does anyone have any suggestions on how i could do partial
edge traversal at the end of the routes based on the function i'm
currently using? also, has this been done already and i just missed
it along the way? a few things about the function i'm currently
using:<br>
<br>
a friend and i came up with a function that takes a lon, lat, and
distance parameters and returns all the lines possible to traverse
within the distance parameter. (attached). in the function the
edge table is named lines, and the cost column is named
distancecolumn, which has values for each edge as the length of the
edge in feet. also, this function finds the nearest node to start
from rather than the nearest point on the nearest edge. the lines
table is in epsg 4269 and the input lat lon are meant to be in epsg
4326.<br>
<br>
thanks,<br>
<br>
