Re: [HOT] paths, tracks and unclassified in West Africa

The source tag is a good option to add for surveys or local knowledge. It has been used for the Malawi Flood Preparedness project (http://hotosm.org/projects/osm_community_mapping_for_flood_preparedness_in_malawi

Re: [HOT] paths, tracks and unclassified in West Africa

That’s a good point. The current definitions take a variety of attributes into account to define what type of highway it is (physical attributes of the highway, size of urban areas connected by highway, the type of use the highway is used for, and whether cars can travel on the highway). Looking

Re: [HOT] paths, tracks and unclassified in West Africa

I like the idea of using the source tag for highways that are tagged for more importance than unclassified. As has been stated before most HOT mappers will be using a small subset of the highway tags. Cheerio John On 16 July 2015 at 16:43, Steve Bower wrote: > One issue with using only a "veri

Re: [HOT] paths, tracks and unclassified in West Africa

One issue with using only a "verified" tag is that you would still have different tag definitions for "rough/remote" mapping vs "detailed/verified" mapping. That could be confusing. The current 24 "detailed" highway tags [1] might distill down to about 5-8 "rough classification" tags, depending on

I think a two tiered system would work well. Officialverified=yes perhaps? I don't think rendering is an issue. Certainly I've seen JOSM used to render or view maps on a lap top for an area. I was quite surprised but the person said an off line map was easily searchable and you could select and

Re: [HOT] paths, tracks and unclassified in West Africa

A fundamental problem is that the current road/path tagging scheme does not distinguish between: • "rough" tagging used for remote mapping during activations, and • "detailed" tagging based on local knowledge. Current tags are used for both, which leads to confusion since the custom "activati

Re: [HOT] paths, tracks and unclassified in West Africa

Some great input is being provided. Primary / secondary / tertiary highways are not encountered very often in a typical HOT project by the average mapper. Therefore even though they are very important to classify and may be mentioned in the training material, they should not be emphasized. Class

Re: [HOT] paths, tracks and unclassified in West Africa

For sure, surface=* (at least paved/unpaved) is a key information on such roads. One should encourages contributors to use it. Indeed, aerial views don't always allow distinction. I saw several asphalt roads with dust on it that look like ground from space. Eric

Re: [HOT] paths, tracks and unclassified in West Africa

My thoughts would be to suggest that mappers in general ignore primary, secondary, tertiary, classifications, if the road is mapped then a local or classification specialist can tag with one of these if required. So, highway=road is made for such a problem. Later, contributors with better loca
