Re: [HOT] Mapping clouds and low resolution imagery
Hi John, While Bing imagery is probably the most commonly used imagery for tracing. There are a variety of other sources. For example, the State Department through their MapGive initiative (http://mapgive.state.gov/) often provides recent DigitalGlobe imagery for specific tracing tasks. Also, data might come from an import (and not having been traced from imagery). Having some sort of measure of "completeness" of OSM is a difficult question. What do you use for the denominator in the equation? Mikel Maron wrote a blog post that might be of interest ( https://www.mapbox.com/blog/how-complete-is-openstreetmap/). Sounds like you're working on a cool project.

The HOT/OSM data is converted into a shapefile using the HOT export tool ( http://export.hotosm.org/en/ ) to link to other data in QGIS. To begin with I am using ground transportation data and population cluster data from OSM. I would also like to include information on impediments to mapping including cloud cover and areas of low resolution imagery in BING to permit identification of potential problems and permit some forward planning. I have looked for tags or presets for identifying these impediments but have not been able to find them. Can anyone help? In OpenStreetMap we map features present in the world, which does not include problems with a specific set of imagery such as where it changes resolutions or where there are clouds, which is why presets do not exist for this. A tool like uMap (http://umap.openstreetmap.fr/en/) might work for sharing this type of data, but it doesn't belong in the OpenStreetMap database. ___ HOT mailing list HOT@openstreetmap.org https://lists.openstreetmap.org/listinfo/hot
[HOT] Mapping clouds and low resolution imagery
I am developing a project to incorporate HOT/OSM data into an application to plan for and manage food security emergencies in developing countries. The HOT/OSM data is converted into a shapefile using the HOT export tool ( http://export.hotosm.org/en/ ) to link to other data in QGIS. To begin with I am using ground transportation data and population cluster data from OSM. I would also like to include information on impediments to mapping including cloud cover and areas of low resolution imagery in BING to permit identification of potential problems and permit some forward planning. I have looked for tags or presets for identifying these impediments but have not been able to find them. Can anyone help? For the moment I have tested a workaround using the OSM AREA tag and the keywords "Cloud" or "Lowresolution" as the NAME. I can then easily create a shapefile using the Esri SHP (OSM Schema) and the OSM Data Model in the HOT export tool. Would this be an acceptable option?
