- Cartofy described difficulties with the OSM classification guidelines for India. He asked the community for help so that ‘we all have better classified roads’.
- SK53 noted that work needs to be done everywhere to improve the mapping of max speeds on
highway=primary.
Community

Did you know …
- … there is a 3D representation of the Swiss canton Jura?
- … that topographic maps use isolines to represent points of equal value? Isolines, also called contour lines, are commonly used to show elevation. They can also represent other variables, such as population distribution or magnetism. Here’s a list of common and obscure types of isolines used on maps. The prefix ‘iso’ means ‘equal’.

- HeiGIT, together with the GEORISKS group at the German Aerospace Centre, are currently offering a master’s degree by thesis in the field of machine learning for characterising building inventories for use in natural hazard risk models. The aim of the research is to describe building inventories based on the combination of ubiquitous multispectral satellite imagery and vector data (OSM building footprints).
