The Generous Open Mapping-Data Quality Focused

Open mapping is a powerful tool for creating and sharing geographic data in a collaborative and open manner. Its benefits include increased data accuracy, improved data integration, and enhanced data visualization capabilities. However, it also has some limitations that need to be considered, such as data quality and security concerns. Open mapping has been instrumental in various initiatives, such as humanitarian aid, disaster response, and urban planning, and has become a vital resource for many organizations and individuals. While open mapping has many benefits, there are also some limitations to consider:

1. Data Quality: Open mapping data may not always be accurate or up-to-date, as it relies on contributions from a community of volunteers.
2. Data Integration: Open mapping data may not always be easily integrated with other data sources, as it may use different formats or standards.
3. Data Security: Open mapping data may be vulnerable to security risks, as it is publicly available and can be accessed by anyone. Data quality is a critical aspect of open mapping initiatives. By understanding the challenges and implementing best practices, open mapping communities can improve data quality and ensure the accuracy and reliability of the data.

I am passionate about geospatial data especially in data quality assurance and having met a platform where I can contribute to a global mapping initiative and humanitarian service that helps respond to resilient communities I became highly motivated. I get Involved with Open-Mapping Validator Fellowship is as a part of Asia- Pacific contributor and stand to support The Open Mapping Hub - Asia-Pacific (AP Hub) envisions creating a sustainable OpenStreetMap (OSM) ecosystem in the region where hopefully I can contribute more in OSM data quality assurances to support open mapping movement by ensuring that the data can be “trusted”, fit for purpose, good enough quality and completeness of data, data and geometry features conform to certain technical requirements.

Contributing since 2019 and participating actively and has generated tens of thousands of buildings and hundreds of kilometers of roads, especially in the Road Mapping Project with Meta and OpenStreetMap Indonesia in all regions of Indonesia, Malaysia, Vietnam, Pilot Team Disaster Response Turkey-Syria Earthquake road networking, El Nino Kenya Mapper, Disaster Response Earthquake Cianjur-Indonesia, and other activities. Becoming the representative from Indonesia at HOT Data Quality Internship 2022 and participating actively in disaster mapping as a disaster activator and Global Validator Team gives me much experience in managing data quality of OSM Data.

Ever since I completed my Validation Open Mapping Guru Fellowship during 2024, I consider it as a gift to my experiences in Validation OMGuru Fellowship and being provided with an opportunity stand to gain my additional exposure, experience, and close guidance from the AP Hub open-mapping initiatives across the Asia-Pacific region and empowers me to build up my OSM skills experience to emerge as contributing open mapping community members in the future The Fellowship has different takeaways for every individual person - it is a unique and complete experience in itself. I thoroughly enjoyed my involvement with the Validating Fellow OMGuru Team, where I gained invaluable experience in data validating by various methods. Learn some quality assurance tool i.e:

• OSMose. Osmose-QA is a quality assurance tool that detects issues in OpenStreetMap data. It detects a very wide range of issue types. It is also useful for integrating third-party data sets by conflation. This tool is great for collecting specific types of issues because it can detect a wide range of issues. Osmose monitors multiple quality control issues in OSM including feature geometry such as overlapping buildings/nodes, incomplete features, and duplications common tagging issues such as missing, unsuitable or poorly formatted tags

• OSM Inspector. OSM Inspector is a web based debugging tool for advanced OpenStreetMap users offered by Geofabrik. On a map you can see several themed views, each with several layers, showing specific details of the OSM data, often with highlighted errors. Layers can be switched on and off, details about any feature is available on mouse click and links lead to your favourite editor so that you can fix problems easily.

• MapRoulette. MapRoulette gives you small Tasks you can complete in under a minute to improve OpenStreetMap. Anyone can create groups of tasks, called Challenges, that the community can complete together. More than 4 million tasks available worldwide that Integrates with JOSM and iD editors

• OSMCha as OpenStreetMap Changeset Analyzer. OSMCha is a web tool to help mappers analyze and review data changes to OSM. The objective of the tool is to help detect vandalism and act on bad changes to the map data. OSMCha is an advanced changeset explorer. Changesets on OpenStreetMap have timestamp, editor used, changeset comment, bounding box of the changeset, username of the author and other metadata

At first, I never knew it was hard somehow using MapRoulette because I used MapRoulette only for validating some challenge in it. In this program I learnt to build my own challenge fixing some spesific issues in OSM Data especially in my country. Learning how to build my own challenge using it in MapRoulette during my last period of my fellowship was hard, stressful and luckily helpful in the end. I’d love to use Maproulette then!

It was really a good and great feeling being part of the Validator OMGuru Fellowship, I am really excited about it and can’t really express it well. The Fellowship has given me the opportunity to learn from experts by doing some data quality control tools, network and collaborate different people to share ideas, learn and impact our community through OpenStreetMap by providing quality data, I am becoming better day by day, I am gradually Improving on my validating skill in another dimension with just few month of the program, Imagine me in couple of coming month, I am super excited about my improvement.
