[HOT] HOT/HDM web rendering

Wed Jun 26 23:07:07 UTC 2013

I think that through the last version of the HDM preset we (HOT) are
firming up what Sev called rightly a HDDM (Humanitarian and Development
Data Model) which serves the purposes of a HOT Operations Preset where both
humanitarian needs and development needs in Developing Countries or Least
Developed Countries are addressed through the OSM tagging way by remaining
now within the tagging logic at work in OSM and by adding/creating hum/dev
tags when not existing or not satisfactory in OSM.

I think that Sev's HDDM is a good name for this overall initiative which
associate schema, preset, forms and thanks to Yohan's neat work symbology
that will show in JOSM, web (CartoCSS) and possibly on other mapping
support (Garmin, OsmAND...).

The HDM is therefore a subset of this overall HDDM and I agree that on a
some aspects of the humanitarian work, it needs a review and that camp
mapping is one of those areas of worthy future work.

In parallel, the next future release of the enhancement of the HOT Export
tool by GeoFabrik which allow to transform osm tags into attributes/ values
of classic GIS schemas calls for tackling as well the building of
crosswalks between humanitarian models by sector of activity and OSM that
will be used to create HOT export jobs.
