A Comprehensive Framework for Intrinsic OpenStreetMap Quality Analysis among Most Cited Paper in Transactions in GIS
Posted in Uncategorized on Sep 9th, 2020
We are happy to share that our paper “A Comprehensive Framework for Intrinsic OpenStreetMap Quality Analysis” (Barron, Neis, Zipf 2013) belongs to the top 5 most cited papers of the international journal “Transaction in GIS” (TGIS). Only recently we became aware of this. Thank you for considering this work.
Certainly this paper influenced also our work [...]
We are back again with a fresh part of the How to become ohsome blog series. In case this 6th part of the series is your first one, or you have not heard from our awesome OpenStreetMap History Data Analytics Platform before (short form: ohsome platform), don’t worry. We’ve added some context, as well as [...]
What does the tool behind the recently published documentation of the ohsome API have in common with a statue made of stones in Egypt? - Apart from the name, both are of course awesome (and now also ohsome). As previously announced, together with the open source release 1.0 of the ohsome API, we have published a [...]
ohsome API 1.0 is here
