HOT Board nomination

Posted by TrudyHope on 24 April 2018 in English (English)

My name is Namitala Gertrude (Trudy Hope). I am a Ugandan IT and GIS professional with over 5 years of experience in developing IT solutions, especially for mapping important features in remote villages and peri-urban areas of Africa. I am currently working in Zambia where I co-founded OSM Zambia and a managing director TruDigital Technologies. I was introduced to OSM in 2013 by Kateregga Geoffrey after I expressed interest in mapping my primary school. I have been an OpenStreetMap mapper since then. .

I am part of OSM Africa and have supported different countries to establish OSM operations and given them guidance where need be. I got to know about Humanitarian OpenStreetMap Team in 2016 when I wanted to use the tasking manager and was impressed at what HOT does. HOT’s ideology resonates with what I believe, so I wanted to contribute more. That is the reason I decided to join the HOT fundraising and HOT summit working groups.

I have led OSM Zambia for two years now and within this short period, the community has grown to over 500 mappers from a handful of mappers when we started out. OSM is now being recognized by the councils all over the country. Open map data sharing is getting more recognition in Zambia and Malawi. I have also been advocating for women participation and inclusion in the mapping community. I have established partnerships with international organizations, government, NGOs, private companies, schools that have all supported our community.

My interest in becoming a board member lies in the reasons outlined below: To grow gender inclusion and get more women involved in HOT and OSM to increase diversity in the community. Increase the presence of HOT in every country in Africa To make OSM the strongest and most trusted map in Africa. To get more partners supporting HOT’s mission

I have a lot to contribute to HOT, but more importantly, being part of HOT will enhance my leadership skills as I hope to learn more about working with a larger organization.

Thank you for taking time to read and I hope you vote for me and change the world together. `

Story so far

Posted by Valerie143 on 23 April 2018 in English (English)
     I was introduced to Opensteetmap by the Unique Mappers Team (UMT) Port Harcourt at the #1 MAPATHON training led by Mr Sunday Victor. He showed how to get registered on Openstreetmap and how to map. For the training, we (those available for the training) worked on project 400 using osm which involved mapping features such as buildings and roads in The University of Port Harcourt and I was added to the Let's Map Our World whatsapp group. From the group, I got to know about The STALL CATCHERS. I participated in the worldwide Catchathon which helped Alzheimer's research. I had a wonderful time catching stalls with the Unique Mappers Team. It was a really fun experience and I enjoyed the pizza.
     I participated in osm task #project-3530 #MXEarthquake 2017 with the guidance of UMT. Alone, I attempted #project-3443 Sierra leone - Regent, Kamayama, Kaningo- Landslide affected area using OpenStreetMap but failed to edit and save  the changeset.
    I have also worked on #project-4370 #mappingperi-urban areas, Lusaka. Mapping this area was successful. 
    I met with the coordinator of Unique Mappers Team, Mr Sunday Victor on Monday 23rd April 2018 for a formal interview and registration as a full member of Unique Mappers Team, Port Harcourt.I am indeed glad to be a Unique Mapper Team member. So far, it's been fun and I know there's a lot more. I'm willing to dedicate my time and passion to mapping the world as long as it does not make me go down academically. This I strongly doubt because I love mapping as well as my course of study, Geography and Environmental Management. I believe spending reasonable time on both will actually help me improve on both. Thanks to OpenStreetMap and my field of study, I'll get to know and map, and soon, visit different parts of the world.

Norwegian airlanes are Openstreetmap user

Posted by Przemo on 22 April 2018 in English (English)

I learned yesterday that Norwegian airlines use openstreetmap data in their entertainment system. Looking for my edits at 12000 m was fun! :-) They don't use vector map, but instead they seem to use raster tiles. The quality doesn't go detailed street level, but it's not required for a flight map.

NCN422 cycle route - Theale to Bracknell

Posted by jpennycook on 22 April 2018 in English (English)

I rode from Theale to Bracknell today to check on the progress of the NCN422 cycle route. There are still large holes, and it's mostly shared use paths rather than proper infrastructure. It will probably be a month or two before I get round to updating OSM with my findings,as there are other things in the pipeline.

Simple script to bulk update the admin_level=? on boundary=administrative ways

Posted by capiscuas on 22 April 2018 in English (English)

Sometimes we find in some cities/countries some boundary ways (the ones that define the political borders of provinces/towns/countries) that has no tag. Example of boundary way without any tag:

For the renders and 3rd party apps that is not a big problem because that way is indide the the corresponding relations with different admin_level, it can be shared by one or many relations, but in my opinion is a good practice to also add tags in the way, specially to avoid amateur users(that don't understand the relations yet) to delete them thinking that are unuseful(I know from experience).

That's why I decide to make a simple python script that parses the .osm file, checks all the ways that belong to a boundary=administrative relation or to many, and updates the way with the lowest/minimum admin_level number found(that way is easier to see that that way is between 2 countries for example, or between two counties or provinces).

The script is the following, based on Dmitri Lebedev's osm2python library (not python3 compatible yet, help migrating).

# -*- coding: utf-8 -*-
# Use python2, since osm2python is not ported to python3

from osm2python.tree import load, dump
from collections import defaultdict

origin_osm_filename = 'boundaries.osm'
destiny_osm_filename = 'boundaries_updated.osm'

# loading the .osm file
osmtree = load(open(origin_osm_filename))

ways_min_admin_levels = defaultdict(int)
for i, r in osmtree.relations.items():
    if 'admin_level' in r.tags:
        admin_level = int(r.tags['admin_level'])
        print(r, 'has no admin_level')

    for way in r.members:
        if ways_min_admin_levels[way.ref] == 0 or ways_min_admin_levels[way.ref] > admin_level:
            ways_min_admin_levels[way.ref] = admin_level

for i, w in osmtree.ways.items():
    w.tags['admin_level'] = str(ways_min_admin_levels[i])

# Saving to .osm
dump(open(destiny_osm_filename, 'w'), osmtree)

The result example looks like this: As you can see the way now has admin_level=5 which is the minimum level of all the boundary relations that way is inside of.

I hope it is helpful for you and you can hack it to do more things than needed.

Welcome to OpenStreetMap!

Posted by Zverik on 20 April 2018 in English (English)

— Yay, new mapper! Welcome to OpenStreetMap!

— I see you are using wrong tags. Please read Map Features and don't come back until you're done. I don't care if it's too long. Go to Google Map Maker if you're intimidated.

— I don't know you. Please go to talk@ mailing list and introduce yourself and reasons for your mapping. Yes, I know you have to sign up using some obscure web page, and then receive unwanted mail for eternity. But rules are rules. Go do it, or leave.

— I see you work for a mapping company. I will be watching you, because you do not care for our map. None of you do. Yes, I am working at such company too, but I care.

— I caught you not tracing from Bing like the rest of us. Please explain your sources and acquire specific permissions for using these. Or better stop.

— I see that among 500 buildings you've traced, 20 have been recently demolished. I know that they are still on imagery and in the registry. But it looks like your quality of mapping will never reach mine. Please go away and never come back.

— Hey, I've seen more edits from you. I think we've discussed it. I don't care if they are good, I have reverted them. Please do not come back.


— Hi new mapper, welcome to OpenStreetMap!

How We Improve OpenStreetMap

Posted by felskia on 19 April 2018 in English (English)

At Development Seed we’re always looking for ways to contribute to open source projects. Recently, we started thinking about how we might be able to help improve the OpenStreetMap (OSM) ecosystem of tools. Of course we had our suspicions, but to insure whatever we came up with had the whole OSM community in mind, we started with a round of user interviews. Below you’ll find our process and findings, in hopes that we can all start supporting tools to serve the greater community.


User interviews are essentially what they sound like, interviewing users to better understand who they are, what they do, how they use OSM tools, and what they feel could be improved within the OSM ecosystem. To try and capture the opinions of such a large group, we broke up the community into 3 different groups:

  • Inexperienced mappers, ones who had only mapped a few times
  • Experienced mappers, including people who map for their work vs people who map on their own
  • People who want map data, people at organizations like American Red Cross or HOT

We interviewed at least 4 people from each group, to ensure that we were hearing from a number of different voices. For the 19 different people we talked to, from Belgium to Japan, we asked them a base set of questions, and asked follow up questions based on the discussion. There were a lot of interesting patterns and ideas that emerged from our conversations:

Having a community is key

  • Most mappers want to map what they know and are concerned about what is nearby to them. This seemed to outweigh the desire to contribute to humanitarian efforts, although that did make mappers feel as if they were doing something good.
  • New mappers often learn more quickly when they have a community, than they would otherwise. Being a part of the community is a huge motivator for people to map.
  • Having someone who can give feedback and make mappers feel welcome increases retention.

Understanding completeness and complexity drives motivation

  • Community feedback and support motivates a lot of mappers.
  • Completeness is a huge driver for many mappers. Knowing what is new and what needs to be mapped, helps them to map more.
  • Understanding, very clearly, how a task is going to help people. Mappers who were involved in humanitarian mapping often didn’t know what the purpose of the task was, which made them significantly less motivated.
  • Communicating the complexity of a task helps mappers better choose a task that fits their skill level. Knowing that a task takes 10 mins or otherwise, is extremely valuable to guide mapping efforts. The skill level of the mappers and the density of the area that is being mapped should be thoroughly considered.
  • Completing a task in 10 mins or less. When tasks are only 10 minutes long, mappers often complete more tasks than they would otherwise.
  • Many mappers talked about not having a good way to see what is unmapped, especially when they’re away from their computers. Not having an easy way to see this information hurts their ability to collect that data when they’re outside of their homes, in their local communities, or are out in the field.

Better onboarding and guides help new mappers

  • Many interviewees commented on how new mappers often don’t understand what OSM is or what it can do. To increase their understanding, more experienced mappers often point them to local communities, the wiki, walkthroughs and most importantly, applications. All of these things are hard to come across or know how to access from the homepage.
  • Adding metadata is a challenge for new mappers. iD’s interface for presets leaves users confused and often leads them select the wrong attribute. Improving autocomplete search and reimagining how new mappers interact with this complicated subject would help.
  • Many mappers are using a trackpad to map and not a mouse, so they often don’t notice the right click features.
  • People learn better by doing. Giving them a way to do this will increase their knowledge.

Being able to easily understand and discover local standards will improve quality

Communities often have their own standards or features that are unique to an area. People who aren’t engaged in the local communities, who don't know what these derivations are, can sometimes do more harm that good. It would be ideal to be able to showcase those local variations so that mappers are more aware of them.

Learning about other mappers helps coordination

Many interviewees commented on how it would be nice to know more information about a mapper. For example, what kind of skills they have, features they’re interested in mapping, potentially how responsive they are to messages. Knowing more information about a mapper could help better build a community, giving people a better understanding of which individuals to reach out to.

Improving offline OSM capabilities will reach new users

Many people in the field or people who often don’t have good wifi connections talked about this. One OSM member commented on how it’s been hard building the community without a way to demo OSM offline.

Other ideas

  • There is a need for an easier and better Overpass, or alternatives.
  • Creating a better building tool for iD.
  • Improve tools to align imagery faster.
  • Better ways to deal with multi-polygon relationships.
  • Being able to have more layers in OSM

Conclusions Per Audience

Another interesting way to look at the data collected is by the different audiences.

People or organisations who use OSM data

  • They want easier ways to import large amounts of information
  • Ways to filter down data - see features that are relevant to them in certain areas
  • Easier ways to export data
  • Being able to map things that don’t belong on OSM, e.g. minefields

People who manage teams of mappers

  • Their wants are mainly focused around getting a better overview of what mappers are doing. Also, being able to show progress in what they’re doing. They want things like:
  • Dashboards
    • Leaderboards (e.g. features in Missing Maps)
    • Being able to see who’s mapping where
    • Seeing change over time
  • Easier ways to get new mappers up to speed so that there are fewer errors

Experienced Mappers

  • Better community
  • Being able to know what is missing or what has changed in their neighborhoods/areas they map
  • Better information in one place. There is a need for more user friendly information on OSM intricacies, and complex tasks such as mapping cycleways.

New Mappers

  • Better tools to help them understand the OSM ecosystem
    • Better way of tagging
    • Better access to lists of resources
    • Better understanding of how HOT and OSM work together (for new mappers there seems to be much confusion over the interaction between the two tabs. They will often close Tasking Manager which obviously creates much more work for them when they’ve completed a task).
    • Better tutorials (Shorter so that they can learn a little bit at a time and/or more easily rewatch a video around a particular topic when they’re confronted with that topic).
    • Encouragement
    • Better community (less intimidating and having a better understanding of how to access the community)

Overall, there is a lot of good potential work here. At Development Seed, our next steps will be coming up with potential projects that fit the needs of the community, as outlined above. Of course, we’d love to hear any suggestions for how to keep in contact with the community or any thoughts about projects to improve OSM moving forward.

Updates on Dasmariñas City (part 2)

Posted by DearPaulPH on 19 April 2018 in English (English)

Project Street-level Photos via Mapillary

Dasmariñas City has to undergo precise mapping, hence DEAR PAUL 24 have boarded the jeep from Salitran to DBB and DBB to WalterMart Dasmariñas at the front seat to provide the updated street imagery where most inner DBB PUV Routes have to base on the correct route line. Some drivers are yet to know the route modernization where the PUV Routes have to map on OSM by DEAR PAUL 24, hence briefing has to be executed himself. Some previously-uploaded street-level photos have resulted in the precise mapping of the sidewalk and roadways, especially in most Congressional Road Networks (Mangubat Avenue segment).

Road Widening, Traffic Island, Drainage and Sidewalk Construction

Dasmariñas City has widened the Congressional Road Network (Burol-J-E-F segment, initially Santa Cruz/San Lorenzo Ruiz 1-San Luis-Fatima section) to consider safety considerations and to avoid wrong-way driving/unsafe passing that may result in another head-on crash disaster. Being the safety and accessibility advocate himself, installing drainage and sidewalk will prevent or mitigate flooding and reduce the pedestrian-vehicle crash incidents, respectively.

Proper PUV Stops and Transit Lanes

Most errant commuters are not staying at the designated PUV Stops (whether signed or with shelter), thus impeding the regular traffic flow. To solve this problem within the Dasmariñas City, including Bagong Bayan (Resettlement Area), the City Government have constructed the Transit Lanes within the Congressional Road Network (North-South segment from Fatima to DLSU-D Gate 1/7-Eleven) along with the island separator, drainage, sidewalk, and public transport shelter specifications. Similarly, the City Government have rehabilitated and possibly widened the Congressional Road Network (Mangubat Avenue segment from Highway 419 to Bridge before DLSU-D Gate 3/DC Park) by 36 meters, which is sufficient enough to provide the Transit Lanes on both directions separated by the island separator. Hence, it is different from the Highway 1/AH26/EDSA in Metro Manila where the Transit Lanes (a.k.a. Yellow Lane) and General Multi-Purpose Travel Lanes are separated only by double lines. By convention, all private motor vehicles (including Taxis and TNVS), trucks and motorcycles must keep off the Transit Lanes since the Transit Lanes are intended for Buses (for 1/AH26/EDSA), Jeepneys, UV Express Services, and sometimes shared with Bicycles.

Green Transportation

Cyclists have to use bicycles safely to reach their desired destination, but most errant motor vehicles are either not passing the bicyclists at the safe distance or encroaching the bicycle lane, which may result in injury or even death. Remember the Marikina City's truck-bicycle accident disaster that led to the death of a single mother within the city's bicycle lane, and to avoid another disaster, being the safety advocate, DEAR PAUL 24 have pre-mapped the shared-use lane and bicycle lane along the Congressional Road Networks. Bicycle Lanes have normally marked with helmeted bicyclist symbol or BIKE LANE markings, along with solid line and/or green pavement. Washington Place has the existing Bicycle Lanes (as listed below) to provide safer and more-efficient green transportation, along with Bicycle Parking Racks (mapped on OSM) and electric tricycles as private shuttle service to homeowners. To avoid impeding the bicycle traffic flow, stopping and/or parking on the bicycle lanes are punishable by law, depending on the jurisdiction. This is the same with the sidewalks where pedestrians are expected to walk safely, and any form of illegal parking and/or stopping within the sidewalks are also punishable by law under Section 52 of RA 4136.

HOT Board Nomination

Posted by Nathalie SIDIBE on 18 April 2018 in English (English)


I'm Astou Nathalie SIDIBE, a Human Ressources Manager, Social Activist, committed to Communities building, volunteer and humanitarian activities for a long time, in Mali.

I got involved in OpenstreetMap Project in December 2014 after two weeks of OpenStreetMap and GIS training with the Projet Espace OpenStreetMap Francophone, ProjetEOF in Bamako, then i cofounded OpenStreetMap Mali and advocate for OpenStreetMap and OpenData projects with a volunteer group in Mali.

So, since January 2015, i’ve been planning and organizing mapping parties, MappingCamps in Mali, cofacilitating OSM trainings in Mali and in West Africa with the support of the ProjetEOF.

I'm personnally involved in developing partnership with Public and Private Administrations, Universities, High Schools, local and International Organizations and NGO.

I'm currently leading, with the technical support of Les Libres Geographes, a mapping project on Organizations working in the Digital fields. This project, called CarteInnov, is initiated and financed by the Organisation International de la Francophonie in 14 African countries including Mali. I'm also Leading the French-Speaking Africa Community for OpenData, CAFDO, in Mali.

Joining HOT Board is an honour and an opportunity to support and contribute more to HOT, to collaborate and learn more from other Board Members, to strengthen my leadership skills and also share my fews experiences leading a local community.

Thank you !
