Zainab Ramadhanis's Diary

Recent diary entries

Maybe most of us have experienced unpleasant situations with maps, like getting lost on the road due to navigation issues caused by incorrect or outdated maps. This problem is particularly troubling in unfamiliar areas or during long journeys. Poor geospatial data quality often leads to these inaccuracies, resulting in significant inconveniences and even potential dangers. This highlights the crucial role geospatial data plays in our daily lives; when it is inaccurate, it can lead to serious issues.

Geospatial data quality depends greatly on who creates it, especially on platforms like OpenStreetMap (OSM), the world’s largest open mapping platform. OSM’s data comes from many different contributors with different levels of geographic knowledge. This diversity can enrich the data but also lead to heterogeneity. For instance, in the picture below, you can see the differences in digitizing done by various contributors. Some highways are more detailed, indicated by the higher number of nodes in the highway line.

Annual Celebration of Open Data and Maps: State of the Map Asia 2022

Posted by Zainab Ramadhanis on 9 January 2023 in English. Last updated on 20 June 2023.

November 2022 was such a pleasant moment because I participated in the State of the Map Asia for the first time. I always wanted to join the SotM in person since 2020 after participating in lightning talk SotM 2020. In 2021, I didn’t have chance to submit my research result because I just finished it on early July. So, I proposed myself as a translation volunteer for Bahasa Indonesia (see SotM 2021).

In 2022, I also planned to join SotM 2022. However, I couldn’t join because I was very busy with my thesis and had to graduate before September 2022. I thought I didn’t have a chance to join any OSM event in 2022 before my friend sent me an Instagram post that Open Mapping Hub Asia-Pacific was looking for scholars. There were three categories of scholars: community nomination, mapping, and map-making poster. I decided to submit in map-making poster category because I didn’t participate at all in OSM local community in Indonesia since I lived in Taiwan to study, and I didn’t contribute much to OSM in 2022. I created the map-making poster about the quality of road data OSM in Jakarta by comparing the OSM data and local government data (see my poster here). Thank you Open Mapping Hub Asia-Pacific for this amazing chance!

I arrived in Legazpi City, Philippines on Sunday, November 19, 2022. Mayon Volcano became the first thing that I saw when I landed at Legazpi Airport. The scenery of Mayon Volcano was very beautiful, I didn’t take a proper picture at that moment, but I took a good one when I visited the Cagsawa Ruins on Tuesday (11/22).

State of the Map Asia 2022 was actually different than any SotM Asia events before, as it collaborated with Pista ng Mapa (Festival of Maps), so the conference was quite long, five days in total. But I didn’t complain, because all the presentations and workshops were totally fun!

Hi everyone, I am Zainab, one of the Indonesian female mappers. Firstly, I want to say thanks to SOTM 2020 for giving me the chance to do this research and presentation it. It is kind of sad we can’t meet directly because of the current issue. Secondly, big thanks for people who listen to my presentation, it’s such amazing many of you are interested with my presentation, so I hope by dropping my slide link can help you to know more about my research. https://docs.google.com/presentation/d/103T_pXDS7i06yh9M_iOvGqCwOlauVs36_blXCGDnjKQ/edit?usp=sharing

Have a blessed day, everyone.
