<div class="WordSection1">
<p class="MsoNormal">Hello<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Could anyone please tell me if pgRouting has the facility to be able to place a point at a specified distance (e.g. 300m) along a linestring from a point of origin?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The problem summed up:<b> Which houses/properties are within a 300, or 600m walking distance from a play area, where the walking route follows the pavement/ sidewalk/ established path route, but not through private property?<o:p></o:p></b></p>
<p class="MsoNormal"><b><o:p> </o:p></b></p>
<p class="MsoNormal"><b>In the past, a circle of 300/600m radius has been used, but this then includes properties which are in actual fact further than 300/600m walking distance.<o:p></o:p></b></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The point of origin is a play park centroid.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The linestring could be a single linestring, such as a highway centre line, in which case there would be a single point at 300m along the linestring from the point of origin.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Alternatively, the linestring could be one which after 150m, meets another linestring, a junction heading west, in which case points would be placed on both the original linestring (at 300m) and on the westward one (at 150m + 150m).
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It is envisaged that we will use this tool to generate walking distances from woodlands, ponds and so on.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Many thanks<o:p></o:p></p>
<p class="MsoNormal">Patrick Higgins<o:p></o:p></p>
