Mapping campaigns

The OrganicMaps team asked users to help fix issues with subway mapping using this validator. Brandon suggested that the makers of the recently released new app for Jungle Bus could perhaps initiate a collaboration?

Chetan Gowda is looking for some feedback on their printable Kannada maps.
Marcos Dione blogged about how he manages the rendering of isolated points of interest at lower zoom levels compared with the same type of POI in dense areas.

Bryce Cogswell announced that Go Map!! v3.0 has been released for iOS. In the diary post Bryce also reminisced about how Go Map!! came to be.
Version 4.0 of the GraphHopper routing engine has been released. ‘Spatial rules’ have been replaced and extended with custom areas. You can use custom areas to customise properties of GraphHopper’s road network in arbitrary areas. A typical use case is to amend rules on a country-by-country basis, such as default speed limits.
NLnet is a foundation that ‘funds those with ideas to fix the internet’. A call for open funding proposals, for projects that would help with creating an ‘open, trustworthy and reliable internet for all’, may cover projects helping OpenStreetMap, and it may be a good idea to apply.

… Richard Fairhurst has written Providing data to OpenStreetMap, an illustrated anglophone guide for local authorities and other data owners?

… that the colour scheme of the OSM Mapnik layer, now replaced by CartoCSS with a revised scheme, was investigated by researchers from Hamburg University in 2013? Richard Fairhurst, who created the original colour scheme, speculated that the effort spent on research was considerably greater than that spent on choosing the colours in the first place.

OpenCage’s latest and very recent #geoweirdness thread is focused on Spain. The thread starts with the image of a multipolygon natural=lava that contributor sergionaranja entered into OSM on the occasion of the current eruption of the volcano Cumbre Vieja on the island of La Palma.
Fancy a bit of aerial surveying using a drone? Be careful not to get too close to aggressive wildlife. A crocodile took out a low-flying drone in Australia, which captured its own last moment on video.
