Re: [HOT] Central African Republic import of WRI data

Hi, I agree with Andrew regarding the importance of creating a connected road network. Actually I already mapped a lot the roads with Bing Imagery and some sections are not covered by high res imagery but sometimes the LandSat medium res allows to identify the roads. In these cases I traced it and

Re: [HOT] Central African Republic import of WRI data

Oh, I forgot that the tasking manager was being used in this import. Since that allows us to track the progress of the import and easily keep track of what is not yet imported then I withdraw my previous objection to a partial import. My concern was mainly that we would "lose" some of the data si

Re: [HOT] Central African Republic import of WRI data

I understand the 'bad data worse than no data argument' but I think that only goes so far. Having a road on the map that isn't terribly accurate is unlikely to cause major problems for people. Having a hospital where none exists could be a major problem, but for roads I think this is less of an i

Re: [HOT] Central African Republic import of WRI data

Andrew, Actually I agree, but I discussed this before with some other OSM/HOT people (It's been so long I don't remember when or who) and it was said that using inaccurate data might be worse than nothing. For the CAR specifically I think using the data might be better than not using it. There is

Re: [HOT] Central African Republic import of WRI data

Regarding areas with no imagery. I would still say to import the roads. A couple hundred meters off is a lot, but it is better to have the 'connectivity' mapped (i.e. what town connects to what other town) than to have nothing at all. Someone following the road in a car does not mind that their

Re: [HOT] Central African Republic import of WRI data

Hi, I'm also prepared to contribute to finish this task and improve the CAR-map. The WRI road-dataset isn't that big but it's not an easy task and still a lot of work. I'm not sure a few mappers will be enough but it would be nice to at least be able to start some work. I was just waiting on the

Re: [HOT] Central African Republic import of WRI data

Severin, The nodes are re-used by the 'replace geometry' tool. So what it does is when you select the two ways and run the tool it takes the old way and tries to 'move' as many of the old nodes (with their ID numbers in the DB) to the positions you chose for your new way, as well as copying over

Re: [HOT] Central African Republic import of WRI data

Hi Andrew, Thanks for your input regarding the import applying rules + the technical tip. One question: how the nodes can be reused if we trace a new way? Please you can try the http://tasks.hotosm.org/job/219 if you want to test Regarding the UNICEF data

Re: [HOT] Central African Republic import of WRI data

In answer to your question on imports, I think the general consensus is that tracing from bing and then copying attributes from this dataset would not be considered an import, it is merely a second source of data used in manual mapping. One other thing to consider is the 'utilsplugin2' which has a

[HOT] Central African Republic import of WRI data

Hi, Sorry to jump so late into this discussion. Actually I am waiting for an answer from the imports list since Mid May. I put it below. So we would like to know if in the case of using a ODbL compatible dataset as a guide for tracing over Bing Imagery (because of the lack of geometrical accuracy)
