Hello
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?
The problem summed up:* 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?*
* *
*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.*
The point of origin is a play park centroid.
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.
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).
It is envisaged that we will use this tool to generate walking
distances from woodlands, ponds and so on.
Many thanks
Patrick Higgins
