Re: [Talk-ca] Telenav mapping turn restrictions

James — Thanks. This means that at the very least we need to check on a 
jurisdiction by jurisdiction basis if these turns are allowed or not. 

Just as a data point, Google maps won’t let you make that turn either [1]. 
That’s not to argue that I am right in any way, just to show that false 
assumptions regarding turns are made outside of OSM.

Re: [Talk-ca] Happy Valley-Goose Bay, Labrador, Canada Data

Hello everyone,

 

Thank you all for your interest and support. As I thought, the first step would 
be to license that data under the ODbL. I don’t think that would take too much 
effort (famous last words?) as we have a very small bureaucracy and I’m always 
one or two people away from the mayor and council. I got some great resources 
and contacts on how to proceed with this step. I’ll be in touch as soon as I 
get permission for our road centerline and street address data to be shared 
with OSM or if I run into any major road blocks along the way.

 

Thanks,

Anatolijs

Hi Anatolijs,

 

Good luck. If you need any help OSM Ottawa would love to help.

Hello everyone,

 

I’ve been a longtime fan of Open Street Map but this is the first time I ever 
decided to help contribute to it. I am the GIS technologist for the Town of 
Happy Valley-Goose Bay in Newfoundland and Labrador, Canada -  
 
https://www.openstreetmap.org/#map=14/53.3085/-60.3463

 

It’s a small, isolated community of approximately 8,100 people and I’m the only 
one with any GIS training and experience. As a result, I’m responsible for 
doing just about everything to assist the town in geospatial-related functions 
and have a very tight budget and not a lot of time to them. One of the things 
there’s been a real interest in is developing some sort of a basic interactive 
web map for the town’s public information (zoning, water and sewer lines, 
attractions for our tourist map, etc.). I’m planning on using QGIS plugin 
qgis2web to do that and use an OpenStreetMap background.

 

Before I can do that, OpenStreetMap data for the town needs to be updated. It 
looks to me approximately five years out of date and the town has been 
experiencing a major boom in the last few years. Currently, the town has 
possession of an updated street centerline network (digitized from 40 cm 
resolution orthorectified Worldview 2 satellite imagery) and an up-to-date 
civic number system with building footprints and parcels for recreational 
spaces and etc. coming later this year. I’d like to share them with the OSM 
community.

 

Before I do that, I’m looking for community buy-in for the project. I will 
start with manually adding the new streets that have been built over the last 
few years and correct any information within the town boundaries that no longer 
represents reality on the ground. If that’s ok with all of you, I’d like to 
make the OSM web mapping for my corner of Canada a little better.

 

Thank you,

 

Anatolijs Venovcevs
