[OSM-dev] Blue Planet
Hello, Today, the Earth is completely blue in OpenStreetMap¹ (at least in the openstreetmap-carto on osm.org) - All the oceans drained into the land. [1] https://wiki.openstreetmap.org/wiki/File:Blue_planet.png I guess the coastlines are broken?

Re: [OSM-dev] Mobile SDK library

I am using Xamarin, a cross-platform language, to build versions for both Android and iOS. There are a lot of open source libraries that provide the SDK/library to integrate OSM maps into apps, but it's a daunting challenge to find the right one. We need an SDK that offers custom pins and that lets us put an order to the pins so that if there are two pins at the same spot, the one that we think is most important will get priority. Moreover, it would be nice if we could use the same SDK for both Android and iOS. Hi, try to work together with these guys¹ - they have a lot of experience with biking apps, and also have worked with different SDKs in the past. [1] http://www.bikecityguide.org/ Does anyone here know of any published apps that uses OpenStreetMap and ordered custom pins? Shouldn't be too hard to implement with any SDK. I'd appreciate any recommendations that you may have.

[OSM-dev] Changesets
Hello list, a friend of mine pointed me to the number of changesets increasing extraordinary in the last days (from ~14k to more than 100k), I ran a little investigation on the daily/hourly diffs: I filtered out changeset numbers in the osc files, sorted and unique'd them. The actual number of changesets appearing in the diffs did not increase. But there were a lot of numbers missing in the diffs, so there must be a lot of empty changesets. And I found a user with a LOT of empty changesets: http://www.openstreetmap.org/user/ettlohw A Mapper registered a month ago, but with 607,556 changesets - and increasing. When picking a random changeset of this user, it shows to be empty: http://www.openstreetmap.org/changeset/23430671 (changeset tags: created_by=Potlatch 2, build=2.3-605-gbec0ea7, version=2.3) Is this a bug in potlatch? Why does the API accept empty changesets? Should I contact the user what the hell he is doing?
