“I will do it. I want to do. I wish I will do it one day…” those sentences are not for this team. There is no place for a single performer. It's a team. Here is not any places for the word ‘I’ without the word ‘We’. They are loves to say “We did it. We had done it.” The team is know that The word ‘We’ is more stronger than ‘I’. But here is a problem is that we don't want to show the team’s work more than they talks. But by this blog we are wanting to inspire others for a competition of humanitarian work. We are a ultimate ghost. No one know us but feels so much by our works.
See the top 10 mappers of the missingmaps leaderboard. Here staying the three mappers (red marked).And if you see top 50 you will find more mappers of the team.
The team is contributed more than 50% mapillary photos.
Not only the statistics are the main issue. We have done all the works with maintaining quality of map data. We are already contributed more than 1.5 million buildings with around 55k km highways. All the contributions are maintaining quality.
We are ready to work for humanity. We was in action on Malaria Elimination, Nepal Earthquake, Tanznia Project, South Asian Flood or Rohinga Crisis. We achieved Chapter Partnership Award 2017 and took 3rd place on the YouthMappers ‘Mapping to End Malaria’ Challenge: Round-03 2017
It is realy true that all the great achievement was came by the teamwork. So that every team is always need to works together to achieve the big things. Best wishes to all chapters. See you all in the field of winners.
OpenStreetMap(OSM) is the greatest invention of modern mapping system in this digitalized world. It is a great source of open data. It is more helpful and informative from any other online Map. In this MAP we get specific data. It is very helpful for peoples. By this map anyone can get information about his queries. Anyone can upload data and also can use data in their necessity. It is also helpful for the organizations that help vulnerable peoples. In this map we get the information about vulnerable area, way of passing, important point, water point etc. that is necessary for any kind of search and rescue operation in disaster. In this map data is free, so it is granted by everyone. It is easy to upload information in this map so anyone can contribute with the information from anywhere, anytime. OSM data is helpful for Vulnerable Capacity Assessment (VCA). By using this data different NGO, Government and International organizations can continue their relief operation. It is also helpful for research work. After all we can say, OSM data is very helpful for people for society as well as country. OSM data is very helpful for disaster risk management. In this map we get the data about identification of vulnerable places, way of passing, important key indicator as building condition, material, and structure by research this information govt. or relevant authority will identify the vulnerable places and take necessary steps to reduce the vulnerability, to reduce the damage of any kind of disaster. By using this data Bangladesh Red Crescent Society or this type of voluntary organization or Government organization like fire service, civil defense can plan their search & rescue operation.
I am Sawan Shariar from Bangladesh. I am an OpenStreetMap mapper and working since 14th May, 2015. I have done field level Mapping using GPS device, FieldPaper, OSMAnd, OpenMapKit, OSMTracker, Mapillary, MapSwipe and OSM Contributor. I upload data by using ID Editor, JOSM Editor and Potlatch 2. My complete mapper profile can be found at Sawan Shariar. I have done mapping for "Data for Action Project" and assisted in various OSM training with Bangladesh Red Crescent Society and continuing as a Super Mapper. I successfully completed The "Training for Trainer: OpenStreetMap" Training from Bangladesh Red Crescent Society supported by American Red Cross.
I am a volunteer of Bangladesh Red Crescent Society. And now I am working as Youth Chief of Red Crescent Youth, Dhaka College Unit (RCY,DCU). After successfully completed the Training for Training: OpenStreetMap I realize that, this training will be very useful for the volunteers of RCY,DCU. So I tried to understood my teachers and principal, how it’s effective and importance. And I successfully done that.
Red Crescent Youth, Dhaka College Unit is a voluntary organization, it started its journey in 2 may, 2004. It’s motto is serve the people. In its long journey it conducted many search & Rescue operation in different disaster. When the authority learn about the necessity and importance of OSM in disaster. They decided to arrange Training for the volunteers. In 22-24 August 2016, OpenStreetMap (OSM) training was conducted at Training room, Red Crescent Youth, Dhaka College Unit. This training was started sharp at 09.00am and it solely attended by the 26 volunteers of Red Crescent Youth, Dhaka College Unit.
Opening session was presided by Sheikh Sabbir Ahmed, Associate Professor of Dhaka College and Teacher In Charge of Red Crescent Youth ,Dhaka college Unit. As Chief guest there was present the pioneer of OpenStreetMap in Bangladesh Ahasanul Haque, Geospatial Data Management Consultant in World Bank Bangladesh. He gave his pleasant speech about OSM that inspires the Participants. Then the training Session started. The Training was conducted by Sawan Shariar, Atikur Rahman atik and Manjurul Islam and assisted by Diluar Jahan & Atikul Islam.
On the first day training session was divided into 4 sessions, which were
Introduction of OpenStreetMap
Introduction and use of ID Editor in OSM
Introduction and How to prepare Field Paper.
Field work: Collect data using field papers
The practical session started with opening an account in ID editor, a web-based mapping tool and it always needed to be connected to the internet. Then all the students made their own OSM account using ID editor before the training session. The participants were learned how to configure the background layer and how to do basic edit with ID editor along with knowing additional information and custom tags. Data that used in editing in this session was specially the home address of the individual participants.
After the lunch break, the participants were introduced to the Field Papers website. The participants were taught how to create a printable map Atlas for anywhere in the world. They were learned how to print and add notes to the field papers. At last participants were paired into 13 team and sent to field for data collection. The first day of the training session was ended with the horizontal development with the shores of knowledge as well as the fervent smiling faces of the participants.
Second Day the training started with its full swing at the same place at the same time like the day before. The Second day of the training, the practical session divided into 5 sessions, which were-
Review on previous day.
Edit Upload data of previous day’s field work.
Field work: Collect data using field papers
Introduction and the Use of JOSM in OSM
Upload collected data using JOSM Editor by participants.
The Sessions started with review on previous day works and upload data of previous day’s field works. After that, participants went outside again to collect data by using field paper. After the lunch break, the participants were introduced with JAVA Open Street Mapping (JOSM). They learned about interface of JOSM, activate imagery providers and upload data. After that they learned how to use JOSM offline by saving the important files for editing. And finally the second day’s training session ended up with uploading their collected data by using JOSM Editor.
Third Day the training started with its full swing at the same place at the same time like the first day. The Third day of the training sessions divided into 6 sessions, which were-
Review on previous day.
Field work: Collect data using field papers
Edit & Upload their collected data
Introduction in HOT &Teach Tasking Manager.
OSM android apps & how to collect data by using it?
Feedback & closing ceremony.
This day’s session started with Review on previous day works and upload data of previous day’s field works. After that participants sent outside to collect data by using field paper and after lunch participant edit & upload their collected data.
In the second session , the participants have instituted by the Humanitarian OSM Team collaborative mapping tool which is known as Humanitarian OpenStreetMap Team (HOT) Tasking Manager and Teach Tasking Manager. Participants also taught how to edit the maps both in teach and hot tasking manager not only editing by ID editor but also editing by JOSM. After that participants were introduced by many maps editing Mobile apps. The mobile apps are Mapswipe, OSM Tracker for Android, Map ME, Vespucci, Mapillary and OSMand.
The training was successful. The credit goes to The Honorable Principal Professor MD. Muazzom Hossain Mollah of Dhaka College. I am grateful to Sheikh Sabbir Ahmed & Farjana Islam, Associate Professor of Dhaka College and Teacher-in-charge of Red Crescent Youth, Dhaka College Unit. I am also grateful to Ahasanul Haque, The Pioneer of OpenStreetMap in Bangladesh and Geospatial Data Management Consultant in World Bank Bangladesh.
If you are a Trainer of OSM or YouthMappers Platform you may have to face some common but very important questions. I want to try to find out this kinds of questions and give its suitable answer.
##01. What is Map?
-----> Answer: A map is a symbolic depiction highlighting relationships between elements of some space, such as objects, regions, and themes.
##02. What is OpenStreetMap?
-----> Answer: OpenStreetMap is a free, editable map of the whole world that is being built by volunteers largely from scratch and released with an open-content license. OpenStreetMap is, as the name suggests, an open source map of the world (www.openstreetmap.org). It has been built up in a concept similar to Wikipedia. It is called the free wiki world map, a collaborative project to create a free editable map of the world. A digital map is always handy for various purposes. It can be used in navigation, in research, in development of location based applications. When the map is free, its usability is guaranteed for everyone. And as OpenStreetMap is open source, its development is rapid and dynamic.
##03. Why OpenStreetMap?
----> Answer: OpenStreetMap is a free, editable map of the whole world that is being built by volunteers largely from scratch and released with an open-content license.
##04. Why don't you just use Google Maps/whoever for your data?
----> Answer: Because that data is copyrighted and owned by multiple organisations like the Ordnance Survey. Google/whoever just licenses it. If we were to use it, we'd have to pay for it.
##05. Who owns OpenStreetMap?
----> Answer: You do. The data and software is owned by you, the contributors. There is an organisation called the OpenStreetMap Foundation which exists to protect, promote, and support the project, but does not own the data.
##06. Why would you use OpenStreetMap if there is Google Maps?
----> Answer: There is no ultimate answer as to which one is better. These two have as many similarities as differences. They are based on different fundamentals, but they solve the same basic human need to know “WHERE”. The key difference between these two mapping environments is a philosophic “Open” vs. “Closed” approach with how the data is collected and distributed. The main difference between these two services is that every edit you make to OSM is owned by you and the community, while every change you make to Google Maps… will be owned by Google. The OSM community is what makes the project so special. Thousands of volunteers from all around the globe are updating the map as their world changes around them. Every update is immediately visible to all other users and is version controlled. There are no corporate map cycle releases, approvals and KPIs that are typical to large organizations. This community is also what ensures the high quality and granularity of OSM maps. Although Google spends quite a lot of time and resources on keeping maps up-to-date, its data quality is not necessarily better than OSM. In many, especially less developed areas, the OSM community has managed to gain even higher data granularity than any other map source. Commercial map data suppliers usually focus on updating map features which are most profitable to sell. Since the OSM community does not have to worry about selling maps, it allows the community to be creative and make maps focused on hikers, cyclists, physically challenged, sailors and practically any interest group. You can map crops, the number of windows on Empire State Building or even the age of a particular tree. Even when it comes to routing and navigation, OSM doesn’t stay behind. Telenav has started using OpenStreetMap data in their Skobbler navigation app.
##07. Advantages of OpenStreetMap
##08. Disadvantages of OpenStreetMap
----> Answer: Documentation:- The official documentation is not complete and not very clear. Many times we must search in forums and blogs to understand some functionality. Incompatibility:- Some users have reported OSM erroneous behavior when it is used in conjunction with other tools. For example: Maps are displayed distorted when OSM is used with Twitter Bootstrap. However, this bug is easy to fix (we will share the solution in another article later).
I’m not saying that OpenStreetMap is perfect. No map is. But when you consider all pros and cons, maybe Google Maps is not the best solution for all use cases. There are many applications where the map should be treated as an important public good, rather than a commodity controlled by large organizations. At the end, why would you rely on a global corporation to tell you what is the name of a street in your own neighborhood? So don’t be afraid and try it out here http://learnosm.org/en
The key highway=* is the main key used for identifying any kind of road, street or path. The value of the key helps indicate the importance of the highway within the road network as a whole. See the table below for an ordered list from most important (motorway) to least important (service).
"Highway tagging samples"
Roads: motorway, trunk, primary, secondary, tertiary, unclassified, residential, service
Link Roads: motorway_link, trunk_link, primary_link, secondary_link, motorway_junction
Special: living street, pedestrian, bicycle road, track, bus guideway, raceway, road, construction, escape
Paths: footway, cycleway, path, bridleway, steps, escalator
Sidewalks : sidewalk, cycleway lane, cycleway tracks, bus and cyclists, lanes:psv, busway
Lanes: number of lanes, direction instructions ("turn lanes"), signposts
It was a memorable experiencing story for my life to visit Gandaria and Moghbazar, Dhaka, Bangladesh for the reason of making digital with the help of OSM, HOT and Data for Action Project. I am Grateful to Mapping Experts Ahasanul Hoque (World Bank, Bangladesh); Dan Joseph (USA) and Nicholas (USA).
Mapping..... Wow.... it's a great work. Its's not my job, it's my passion. I just want to present my own town to the world.
