[Talk-ca] Newbie to the Canadian mapping scene looking forexamples of well mapped areas

Hi Tyler and all!

I would consider Sherbrooke as a well mapped area!-)

Actually there are plenty of good examples around the country, each of them
having their own "color".

Welcome

Daniel

Hi Tyler, 
Welcome.

Yup, thats alot of houses.  Great work!

A couple things.

1 - You can use Toporama from Natural Resources Canada, and set it up as a
WMS layer in JOSM

http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en?LAYERS=limits,vegetation,built
up_areas,designated_areas,hydrography,hypsography,water_saturated_soils,land
forms,constructions,water_features,road_network,railway,populated_places,str
uctures,power_network,feature_names
<http://wms.ess-ws.nrcan.gc.ca/wms/toporama_en?LAYERS=limits,vegetation,buil
tup_areas,designated_areas,hydrography,hypsography,water_saturated_soils,lan
dforms,constructions,water_features,road_network,railway,populated_places,st
ructures,power_network,feature_names&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMa
p&STYLES=&EXCEPTIONS=application/vnd.ogc.se_inimage&FORMAT=image/png&>
&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application/vnd
.ogc.se_inimage&FORMAT=image/png&

You can trace all you want & as much detail as you like.  Toporama is
derived from the exact same source as CanVec & GeoBase, and it's the same
level of detail.  (you might have seen that on the Canada wiki page)

There is a TONNE of information, so i'd recommend just mapping what you
like.  Others will join in once they see your area so well detailed & let
the competition begin!   (Quality in a small area, beats quantity over a big
area IMO)

2 - The Town of Duncan, BC On Vancouver Island is perhaps the best  mapped
place in Canada. 
Although we did get some help from  (Local Mappers / Landsat / Yahoo imagery
/ CanVec/Toporama/GeoBaseNRN/ GeoBaseNHN/Cowichan Valley Regional District /
Atlas of Canada / NRCan geogratis ).   Great work Kevin Smith! (who is the
top contributor)   This is a wonderful example of a combination of efforts
from multiple sources.

A purely personal point of view.  I like the footpaths, Google doesn't have
these.  I'm not so sure about the houses as a block.  I'd be more inclined
to drop in street numbers in post code blocks using addr:interpolation
<http://wiki.openstreetmap.org/wiki/Key:addr:interpolation> . 

for example http://www.openstreetmap.org/?lat=45.47761
<http://www.openstreetmap.org/?lat=45.47761&lon=-75.484175&zoom=18&layers=B0
00FTF> &lon=-75.484175&zoom=18&layers=B000FTF

The reason for this is to cram in as much useful information as possible
whilst minimising the number of points in the GIS database.  Each house has
a min of four points as a block, using interpolation two points can
represent a block of ten houses.  Be aware though that I worked as an
assembler language programmer forty years ago when computer resources were
much more expensive than they are today but I still like to consider them so
I'm bias.

Yup, and how you already have houses drawn in.  It will make the map look
even better.

Cheers,
Sam

Postcode searches don't exactly work as they should in Canada at the moment
but being able to look up an address helps routing software etc.

Any buses run in the area?  Bus stops can be useful to people trying to find
their way by public transport.

Any businesses or stores around?  Supermarkets perhaps that are open 24
hours?  Tag them with their web site, phone number, type of business etc.
Especially decent coffee shops, you never know I might want to visit
sometime.

OSM is electronic so add tags in JOSM perhaps to POIs.  Once the data is in
the database different rendering solutions can pull or present different
images based on what the user would like to see.

I discovered OSM a few weeks ago and have been hooked since.  I've been
refining the existing map data for my subdivision, adding new roads,
cleaning up existing ones, and adding POIs.

I've also traced all the houses in my subdivision and am planning to head
out with a stack of WalkingPapers and gather POIs and address mappings:

Can anyone out there recommend good examples of well mapped areas in Canada?
I'm just looking to get a feel for what people are mapping, and how they're
handling interesting road junctions, etc.  I realize the Wiki has guidelines
for lots of this but its always nice to get some tips and tricks from other
sources as well.

Thanks!
Tyler
