My engagement with OpenStreetMap began through my involvement as a YouthMappers volunteer, where I developed a strong interest in the power of open geospatial data for development and humanitarian action.

Calvin Amevienku is my name, a YouthMappers volunteer regional ambassador to Ghana. I have had the opportunity to support and connect student chapters, promote mapping activities, and encourage youth participation in open mapping across my region and beyond. This role has deepened my understanding of how collaborative mapping contributes to capacity building, digital transformation and community resilience.

Through my continued involvement with the Humanitarian OpenStreetMap Team (HOT), I have contributed to humanitarian mapping efforts that support data availability for underserved communities and crisis response. These experiences have strengthened my appreciation for the role of volunteers in building and maintaining high-quality open geographic data.

Being nominated as a 2026 HOT Voting Member is both an honour and a responsibility that aligns closely with my work as a YouthMappers Regional Ambassador. It represents a transition from active contribution to meaningful participation in governance and decision-making within the HOT community.

If selected, I aim to represent the perspectives of YouthMappers and regional contributors, particularly from Africa, ensuring their voices are reflected in HOT’s decisions. I am especially interested in strengthening youth engagement, supporting local chapters, and advancing capacity building initiatives that sustain long-term participation in open mapping.

I am committed to contributing constructively to HOT’s governance processes and to strengthening collaboration among HOT, YouthMappers, and local mapping communities worldwide.

Cheers!







I recently discovered this. You can survey for Open Street Map easy if you use your camera with location tags turned on. Take lots of pictures of anything that could be added or updated while you shop, walk or drive. Then later you can go through your pictures and use the location to find where they were taken. Compare the location tag against satellite images, and add everything you find useful in your photos.

I recently went on a trip and I’m adding businesses, addresses, stop signs, speed limits to OSM this way and its really helpful. Ive been able to add so much more details that I didn’t even know I saved in my photos. Try it!

























The main improvement in this release is the support for shared corner fillets. Now, when two open ways meet at a junction, the rounding applies across both ways as a single continuous operation.

For the moment the wiki only describes the tagging of protected heritage in the four Belgian regions that get the heritage=4 tag. In Flanders, Wallonia and Brussels, the heritage agencies also maintain a (more comprehensive) inventory of heritage next to a list of protected heritage items. (the situation in the German speaking region isn’t well known by me). For example in Wallonia, the heritage inventory lists 51,000 items, including 9,000 protected items.

This is a proposal to follow the practice of heritage agencies and assign a tag to all inventoried heritage objects: add a tag for heritage objects inventories: heritage=5 * This will make the heritage items included in an inventory identifiable and searchable. Until now not protected inventoried heritage in Belgium only get the tag historic=x as other “old” items. * A tag for items that are only in their inventory is already in use by OSM France and also Italy, Netherlands, Bulgaria, Hong Kong also have different types of the tag heritage. (In Belgium we use heritage=4 for protected heritage as some other countries but a lot of other countries use heritage=2 for protected heritage. The used number is specified per country). * The wiki now describes heritage as “Site/building/object registered by an official heritage organisation”.

In the last few years, there have been a number of changes at the heritage agencies in Flanders and Wallonia.

Wallonia The agency AwaP (Agence Wallonne du Patrimoine) has, next to the ‘’Patrimoine culturel immobilier classé’ for protected heritage, an inventory of that is now called IRP Inventaire Régional du Patrimoine (until recently it was named IPIC Inventaire du Patrimoine Immobilier Culturel, a name that can still be found in many OSM entries). It is interesting that heritage objects in OSM include a link (with a URL) to the Walloon IRP inventory, as this contains a detailed description and history of the item, as well as a reference to its status as a protected and exceptional site, if applicable. That description and history appear only in this inventory and not in the inventory of protected heritage, which only provides a very limited justification for the decision to protect the site. With the proposed additional tag for heritage, items in the IRP inventory get heritage=5 but protected items still get heritage=4.

Brussels The situation appears to be similar to that in Wallonia with an ‘Inventaire du Patrimoine Architectural Bruxellois’and ‘Le registre du patrimoine protégé’.

Flanders 1. There is a scientific inventory of heritage objects “Erfgoedobjecten” containing a fairly detailed description and history of the item. There are no legal consequences of being included in that inventory. It would be a good idea to include that link at the item in OSM so that anyone interested can find the explanation. The URL contains the word “erfgoedobjecten” and links to the description, with links to the “Aanduidingsobject” and its protection if applicable. 2. Indicative objects “Aanduidingsobjecten” are recognised architectural heritage and imply legal consequences that can be limited or extended if they are protected heritage. The proposal is to assign in OSM the tag heritage=5 to these heritage features and heritage=4 to protected heritage features. Tagging the URL to the Aanduidingsobject is less valuable as it includes very limited information about the object. The URL to the Erfgoedobject is more interesting. Including the ID number in the tagging is valuable to trace back a heritage item. There are heritage objects that are not listed as “Aanduidingsobject” mostly it are landscape features but it can be architectural feature. If applicable they can get the tag heritage=6.

German-speeking Community The situation isn’t known to me.

Question about this propasal: Are there objections or remarks against the proposal to add the tags heritage=5 and heritage=6 for heritage tagging in Belgium? Are there objections or remarks to make a wiki about heritage tagging in Belgium as described above and change menu’s in JOSM and eventually ID?
