2019-09-22, 16:30–17:30 (Europe/Berlin), Mathematikon C

Using JOSM Plugin to mapping road in advanced way and improving data quality in OpenStreetMap.


This workshop will examine about a Turn Restricition Plugin in JOSM.

Nowadays, popularity of OSM has been spread all over the world. Moreover, based on development of OSM itself, many parties has been used it in any sectors including routing services.

However, road mapping is not as popular as POI Mapping eventhough road data is also important as polygon or buildings in OpenStreetMap. So far, OSM mappers mostly focus on mapping public facilities and POI to complete their area in OpenStreetMap.

Thus, this workshop will be focused on road mapping in JOSM using turn restriction where the participants can learn more about mapping road in advanced way. Moreover, this workshop goal is to improve more knowledge around OSM mappers community that can lead to improving Data Quality in OSM especially roads.

In this session, I will share my experiences as OSM mapper how to use this plugin. A lot of interesting experiences that I had such as how implemented this plugin in some of my mapping project activity and what challenges that I had and how to manage with it. Finally, I will share to all of the participants about the result in some area. Comparison between before and after OSM data in each city and the benefit that we could get from the data to OSM community in Indonesia.

I have contributed in OSM and joined with Humanitarian OpenStreetMap Team in Indonesia since 2012. For more than 5 years, I have been involved in a lot of projects using OpenStreetMap in Indonesia. Some of my key contribution are:
First, I make OSM Module (as an editor) that combine basic and intermediate learning material for OpenStreetMap. At the beginning, This module was created for my coolaboration project with Wikimedia Indonesia in East Kalimantan but now after the project finished it available and free to download in https://openstreetmap.id/docs/ModulTutorialOSM25Januari2015.pdf

Secondly, I also make OSM wikimedia pages about refference objects for Indonesia Mapping. I made this page because there was misunderstanding between general page about Map features and real objects in Indonesia. So this page aimed to guide Indonesia OSM users and mapper to map right object with the right information. (https://wiki.openstreetmap.org/wiki/Id:Referensi_Atribut_Objek_OSM_Indonesia)

Thirdly, I was involved to make a document about OSM Data validation. This document now used in most of our training and we adding it to OSM wiki page as well. (https://github.com/harrymahar/indo-data-validation)
