Hi Dimitri and other listers,
If Manifold System 5.5 could do the following thing (besides all those
wonderful
things that obviously Manifold can already do - for an incredible price...
- We are now using ArcView and Arc/INFO...), then the department I work for
is a potential buyer of some 11 to 15 licenses of the Enterprise Edition...
A. Showing on a map some set of points (or lines) which is being defined
not by their own coordinate pairs, but by the following fields in a
table
- the "ID" (that is matching a specific polyline's ID in some route
drawing
or in some oriented network drawing in Manifold?),
- the "From" milepost (in kilometres, or in other metric units),
- additionally the "To" milespost, if there are not points, but lines
to be dynamically shown on a map)
... by applying this database file (stored as ASCII, dbf, or Oracle)
to the route drawing (or to the oriented network drawing in Manifold
System 5.5.?)
B. Having an option (Save As or Convert) for this points/lines
(which do not yet have their own 'static' coordinates, but are still
'dynamically' dependent on a route/network drawing) to make from them
a new, independent (i.e. not based on a network or route drawing,
anymore)
point or line drawing.
Do we ask too much?
If not, I may recommend buying Manifold System 5.5 to many other that I
know
in our country (like "landscape architecture" studios, municipalities,
government agencies
etc etc) who I know would be happy to use it instead of costly alternatives
with costly upgrades...
Cheers

Below is a discussion on the topic I have found by searching through the
Manifold-L list, but the discussion was concluded by a 'do it yourself'
tip :(

Depending upon what exactly you need to be able to do with the points once
they are created I think it could be scripted using the endpoints and the
intrinsic fields "Bearing" and "Length."

[...] long time ago I had sent an email to sales asking if Manifold
supports
'Dynamic Segmentation'. They replied 'NO', saying though that 'we could
program that'.
[...] I remember [...] Dimitri said that a specific 'Network Analysis'
Add-in could be
coming out after release 5.0.? [...] [D]oes it mean that everything that
was going to
be a part of this 'Network Analysis' extension is built into 5.5?

Subject: [Manifold] Mapping Independent Points along a Route
I have a series of routes imported into Manifold (from ESRI).
These routes imported correctly and have attributes,
such as milepost, correctly imported.
Essentially, these routes consist of a series of polylines (endpoints
are georeferenced) and a starting milepost (0.1 mile accuracy)
at the start of the polyline.
[...] I have a series of accident files (bringing them into Manifold
is no problem) that identifies the accident by milepost (at .1 mile
accuracy).
I cannot find an easy way to construct a geocode independent points
along the polyline (which could be anywhere within the polyline), using
the common references between the polyline and the accident file.
Any suggestions? Within ESRI this is "event" point that is mapped along
the route.
