Summary: Using GIS for a water loss control system for a pipe network
Keywords: GIS, pipe network, water loss
Date: 29 Sep 92 07:42:44 GMT
Organization: Infotek, CSIR

Hi

I'd appreciate it if anyone could provide any pointers to any literature
and/or software concerning a water loss control system for a pipe network.
Specifically, such a system would be used by a municipality to model the
predicted water flow and pressure at various points in their pipe network,
and these numbers would then be compared against actual measurements, to
help the municipality detect leaks to reduce wastage. The problem is
decidedly non-trivial, given that the networks consist of loops and alternative
routes, and also given that significant portions of such networks are not
recorded! Given that South Africa is due to run out of water in 20-30 years, 
this is obviously quite an important issue to us!

I would think that it would be beneficial for such a system to run on top
of a GIS, and I suspect that dynamic segmentation might be a useful tool.

Given the vagaries of news group reception out here, I would appreciate
emailed replies. If there is any interest, I'll summarise the responses
I receive.

I hope that that is not too many ``givens''!  :-)

Thanking you in anticipation
Antony

I could find no official definition in our glossaries here.  However...

The term "Enterprise GIS" has been around the utilities ("AM/FM") community
for at least 7-10 years.  (See an IBM tech paper from the early 80's by
Edward Popko entitled "An Enterprise Implementation of AM/FM").
Indirectly, at least, it can probably be tied to the "Information as a
corporate resource" ideals of Diebold and others.  However, the term has
become one of those slippery things which can be stretched and squeezed to
mean whatever it takes to get through a situation.

In general terms, I think, the phrase usually assumes the GIS in question
is operating in a large organisation where other, usually non-spatial
databases also exist.  Through some requirements study, it has been
determined that data stored in the GIS and in at least some of these other
databases are of "corporate" importance (*i.e., of interest to more than
"n" different groups of users).  A good example might be in a municipal
government which maintains a GIS for engineering or planning purposes, but
also maintains address- or parcel-related information in other databases.
In many cases, these databases may be large, sophisticated and
well-entrenched, and will probably remain independent of the GIS for
technical or institutional reasons.

Against this background, I would intepret an "enterprise GIS" to be one
that recognises other external files or databases in the organisation and
offers some degree of communication, compatibility and interaction with
these to fulfill (usually) specific and well-documented operational
requirements.

In this case, "some degree" depends on the vendor and the customer in
question, and *may* include a spectrum of capabilities ranging from:
* data import/export between the various databases in an organisation;
to...
* remote login between systems and NFS-mounting remote directories in a
client-server environment;  to ...
* real-time linkages between different databases; to...
* distributed database management across different platforms in different
departments.

Is this how vendors interpret an "Enterprise GIS"?  Even if it is, this is
probably much too rambling and convoluted an explanation.  Can someone from
one of the vendors provide a clearer definition?

Cheers,

I might not state the problem clearly, or you take the approach too easy.
A lot of responses refer me to CLIP or intersect, etc.  What I care is 
HOW ARC/INFO does it and how efficiently.

Say I have a coverage named "swiss cheese", because 80% of area inside 
the coverage hull are holes. To cookie cut other coverages by the "swiss
cheese", the all the database items of other coverages in the holes should
not be accessed at all for the performance concerns. As far as ARC/INFO
documented, CLIP or other functions access all the items IN THE HULL,
INCLUDING those in the holes. Then, it filters them by examining attributes
and xy's afterward.  As the result, the data access hit rate is as low as 20%.

We use GIS not for interactive queries. We use it to support VRP or VRPTM,
At each run, there would be thousands of GIS queries. How long it takes
to do these CLIP and RESELECT, etc? ARC/INFO solution to VRP, or TSP, is to
have a special data set for routing problems. They are not using CLIP, or
UNION, or INTERSEC, etc, to access the general purpose data set. because it is 
the most efficient way they can do. However, I don't know if it is right by the 
concept of a DBMS. We may be told GIS is not defined as a DBMS; we ask too 
much from it.

Thanks to all of the friends who give me precious inputs to the question.

Here at Digital Mapping Services we have used MapInfo version 5.03
for Dos quite extensively, but have not worked with the windows
version at present.  If the digitizing transformation works the same
for both versions, we have found that by picking any two of the
control points inline vertically or horizontally will give a
corrupted transformation.

Inother words when you pick your control points:

                1) make sure none have similar x or y coordinates
                2) this is usually done by picking control points
                   that form a triangle around the study area
                   (this seems to give the best transformation)
                3) make sure the area to be digitized is contained
                   within this triangle
                4) magnify the area and have snap mode on when picking
                   the same area on the map

Good Luck I hope this helps

I work have access to several ARC/INFO workstations and are very

You can obtain more information about the Corine project  e.g. in

is in charge of this project for our country. Generally I think you
would be able to obtain more info at ESA (European Space Agency) and
it is mainly SPOT activity.

There is one discussion group on BITNET that I have read about that might
interest you.  The group is called AQUIFER, and the node address is:

AQUIFER@IBACSATA.EARN

to subscribe, send this command to LISTSERV@IBACSATA.EARN

  SUBSCRIBE AQUIFER

and place your name after "aquifer": this will put you on the list.

I got the information from:

Kovach, W. L., July 1992, Conversations in the ETHER: Geotimes, v. 37 n.7

This article mentions several other discussion groups for geography,
geology, and other natural sciences, and is a good source of info.


I hope this helps...
