[obc] Maps

2002-06-05 Thread Kevin Nelson

Since making maps puts bread on my table I feel adequately qualified to 
comment on this subject.

Producing maps can be expensive. Today, all maps are created using GIS 
(Geographic Information Systems) - computer software that combines 
graphics (lines representing roads, shapes representing lakes etc.) with 
attribute information about those graphics (road names, lake names etc.)
 
Desktop versions of these systems start at $2000. Then you need to buy 
data, although a lot can be had for free if you know how to find it. 
Then you need to manipulate the graphics based on the attributes. Then 
you need to decide how to publish the data. And when teh data changes - 
a new road gets built, or a dirt road gets paved, somebody has to update 
the database. The prohibiting factor in these types of initiatives is 
time - time is expensive.

Publishing takes two forms (at least as has been requested on this 
list), internet or hardcopy (paper).

Internet mapping is a world in itself. There are two general options: 
provide map images (in .jpg, .bmp etc) of a map that a GIS technician 
has prepared. End users on the internet access this image the same as 
opening a picture of say, Lance Armstrong, but a map image is generally 
quite large - it has to be in order to provide the necessary information 
in a legible manner. This causes issues with file storage, download 
time, and end users having the right tool to view the map etc. These are 
all issues that can be overcome, but not easily or cheaply.

The other option is more interactive for the end user, but very 
expensive. It involves a GIS web server (hardware), another type of GIS 
web software, and time spent developing a user interface to simplify the 
access for end-users i.e. programming a button to display the OBC route 
from Ottawa to Manotick. This is the future of the mapping industry, but 
right now, a minimum cost of $50,000 to implement would be my best 
guess. (Most ISP's don't have the required type of server). An example 
of this type of website is Mapquest.

Hardcopy maps again require lots of time. The same data would be used to 
do the internet mapping, or the hardcopy maps, but it is a question of 
time. How to colour the roads, how to label the roadnames, what size 
paper to put it on etc. I don't think the OBC could sell enough to make 
the investment worthwhile.

So although the idea is great, and it would be fun for someone like me 
to do, I don't think that we are going to see OBC route maps on the 
internet anytime soon, or an official OBC hardcopy map for sale in the 
stores. Time to produce and cost of producing are just too prohibitive 
at this time. 

Many people have mentionned great alternatives here. try them. Or, get 
out on your bike, turn down a road and see where you end up.

Actually, the OBC did sell a set of route maps and they were available
in stores years ago (I still have a set).  If I recall correctly, it
was spear-headed by Dwight Yachuk.

The technogoly was simple -- take an existing hard copy map (topo maps
if I recall), then draw the routes on with a pen.  The nice part about
the maps was that they were done on tyvec (sp?) so that they weren't
ruined if they got wet (like in a jersey pocket)

Beaconsfield's maps are on line.  (http://www.clubcycliste.com) They
don't appear to be scanned, so perhaps they're using a more
sophisticated approach along the lines of a GIS system.

For those interested about inexpensive maps there is a solution: MapArt.

MapArt publishes a CD with maps for Ottawa and the region which will show 
the essential routes and bike paths. You can pick it up in almost all gas 
stations for $19.95.

I have been using it for over a year to measure bike rides and running 
routes and the distances are pretty close to the truth. I even compared it 
to a more sophisticated software (MapInfo v 7.0) and found little 
differences in distance measurements.

MapArt has a web site and publishes other regional maps:

2002-06-05 Thread Spencer Cheng

There is at least one open source GIS software system available called
GRASS( http://www3.baylor.edu/grass/) . It is not the easiest piece of
S/W to use and has a bit of learning curve. It is available for
Linux/Unix  and also Windows if you have Cygnus installed. It's
originally a Unix package which also now available for the Mac :-)

GRASS is tough on systems :-)

[obc] June Newsletter

2002-06-05 Thread Rod Plunkett

I regret to announce that the Newsletter will not be delivered on time again this 
month. I will spare you the details as I would probably have to retain a lawyer if I 
said what is really on my mind right now. Anyhow, I was counting on the Newsletter 
being delivered before the RLCT so I have decided to post the PDF version on the 
website for a few days. You will likely get the hardcopy some time next week in the 
mail. You can download it from the following URL:

http://www.cyberus.ca/~obcweb/Newsletter/Jun02.pdf

Please note the above copy does not include the calendar which can be downloaded at:

http://www.cyberus.ca/~obcweb/OBC_Cal/MonthlyStyle.pdf

On the up side, OBC members can read it and print it off in colour if you have access 
to a colour printer. The down side is the June newsletter is now In The Wild and 
non-members have access to it since this list is the only means I have of making 
announcements. If you are a non-member and download it, this is freebee compliments of 
the OBC. I hope it makes you consider joining. 

Please pass the link around to all your off-list OBC friends. Please also note the OBC 
is going to get hit with a high Internet bill this month because we have to pay for 
any bandwidth we use over a certain threshold. Another freebee for non-members. 

To all - Please DO NOT ask us to post it every month. It will only happen if access to 
it can be limited to members only. Unless you know how to do this and are prepared to 
volunteer to implement it, don't bother suggesting it.

Enjoy.

An exercise for students of linear programming: What is the optimum
number of people who would have to opt for electronic delivery only
versus hardcopy only to minimize the cost to the club?

Hard copy costs: printing, postage
Soft copy costs: bandwidth
Additional constraints: Postage discount if number mailed exceeds 1000.

Memories of simplex dance through my head...
(Weren't they a component maker?  If so, this post might actually have
something to do with a bicycle...  Imagine that!)

Felecitations Rod.  The June issue looks really good, especially in
colour.  Further, I think that this issue does an excellent job of
promoting the club, so being in the wild might not be so bad anyway.
