Hello,
Hi @awisemanapple I got your e-mail. Yes, there are quite a bit of work that needs to be done. I am currently collecting house level data information and updating the road data as I get them from the government sources. Even their data is often misleading or mislabeled so I have to try to fix the classification. I am also, fixing the connection and direction as I am getting more data. There are some changes on the road lately since there are some road constructions (new roads and repaving). It's been very difficult with getting that data. I often try to update the roads if I see updates as I am driving around the city. The city admin also has started to label roads in "odd" manner where there are letters and number combo. That's the data I have been updating. I will be glad to get some help and would love to work together to fix up the roads.
@teddyumd thanks, that sounds great. Is this for Addis or another place? If there are public resources for the government, that would be really helpful.
@awisemanapple, unfortunately, there is no "officially" public data store this information is available. Most of the data I had was from informal sources. I also have started a company in Addis Ababa that collects geolocation data. I have 15-20 people walking around the city collecting data. So when I find a road name, I try to update it.
Task Description
This task outlines work to improve map data in Ethiopia. We plan to work on improving the road network, such as adding missing roads, fixing network issues such as missing connections or crossing roads, and other related issues. We also plan to update and correct coastline and water features as we find them, and correct and improve land use and land cover polygons where needed, such as airports, national parks, forests, colleges and universities, and so on -- remove duplicates, correct the boundaries, fix incorrect tags and other similar things.
Improvements that will be addressed include the following:
Mapping Guidelines
The team will follow OSM and local policy, along with any other guidelines as appropriate.
For water and coastlines, the team will follow OSM coastline guidelines, waterways policy such as water and natural=water and local policy along with any other policy as appropriate. Some coastlines are connected to administrative boundaries, in which case we will adjust both if appropriate Where we see them, we will remove the
source=PGS
tag, which was from an earlier coastline import that needs to be cleaned up. We received a message on the India coastlines project requesting this, and it is commonly done in other coastline improvement edits.The team will use imagery and data sources below as needed for mapping in Ethiopia.
When in doubt, the team will use the existing tags and data which are used locally. The history in JOSM (ctrl-H) identifies what previous mappers added and their notes and/or explanations regarding changes made. This history can also show if a previous mapper has visited that area or has expert knowledge or sources.
We have also messaged talk-et to get feedback and suggestions about the project.
Our team uses the hashtag #adt (for Apple Data Team) for our edits.
Area of Focus
Throughout the country.
Local users RasRoach and TeddyUMD said there are many issues with road classification and disconnected roads.
Tools
The team will use JOSM for completing the task. JOSM has validation warnings for road networks and other possible issues that are important to prevent improper changes.
Sources
The team will apply image offsets as needed.
Changeset Comments
The team will provide changeset comments that are in compliance with OSM changeset guidelines.
Error Detection
The team will check for errors visually and using JOSM validation warnings prior to committing the changeset.
In addition, the team will review its work in accordance with validation guidelines such as the OSM Wiki and LearnOSM validation guidelines
