Map Your City ongoing project by BHOOT

Map Your City ongoing project by BHOOT

Map your city is a project initiated by BHOOT in collaboration with Pathao Ltd. to map down all the major cities in Bangladesh. It started long before the grant, but this grant gives a big push in the project as this help us to engage more volunteers with the project. Before the grant we only focused on completing Dhaka city, but after the device grant the project just got a shift and we completed most of the major cities in Bangladesh, such as Chittagong, Sylhet, Khulna, Rajshahi, Comilla, Jessore, Mymensingh, Narayanganj, Gazipur, Jamalpur. Currently, work is going on for other major cities like Savar. Eventually under the project the community will map down all the major cities of Bangladesh with all the roads connecting to them. This will establish a full country-wise connectivity.

South Asian Flood

South Asian Flood

Last year in July- August many south Asian countries were affected by a sudden flood. Among the southern countries, the low-lying countries like Bangladesh were the worst sufferers. To deal with the devastating after effect and also to set up a defense mechanism to the harshly affected areas the Red Cross and other international NGOs started working. HOT initiated an activation straightaway named “South Asian Flood Activation” to support the AID agencies. Led by BHOOT the OSMBD community responded to the situation and with the help of the grant devices the team started mapping the residential areas and major connecting roads of that affected areas. It is also an ongoing project to map the households and relating roads of the affected areas which will help to build a baseline map of the area and ensure effective response mechanism for any critical situation in the coming monsoon.

Clean Dhaka, Smart Dhaka: Identifying the Opportunities to Make Local Urban Waste Management More Sustainable and Resilient Using OpenStreetMap Data

Being one of the most densely populated cities, Dhaka faces a tremendous challenge in terms of waste management. Initially several initiatives have been taken to manage waste in a more coordinated way but first of all most of the organizations lack in proper geo-location of the waste related sites. So, the primary target of the project is to create a geodatabase waste disposal points of every size. This is more of a research project initially with the possible solution implementation advocacy & activism phase Upcoming. This project is initiated by BOIL (Bangladesh Open Innovation Lab), the mother concern of BHOOT.

Korail Slum Mapping in Dhaka city for NIHR Health Survey in Collaboration with University of Warwick, UK

Dhaka is one of the most densely populated cities in the world. As a result, the health situation is a major concern. This situation gets worse when it comes to the slums where thousands of people live in cluster of houses in a very small area. Because of the poor living condition, drainage system, inadequate ventilation etc. these slums are the potential areas for different diseases and therefore require proper medical interventions to save the people living here.

To understand the situation better, NIHR and Warwick University are jointly facilitating a research in the slums of 4 countries. The purpose of the research is to identify the location and details of medical facilities in the slums. In Bangladesh, Korail slum is home to around one lakh people who are living in a very small area of 9 acres. BHOOT is supporting the project with initial mapping and Structure verification.

Dhaka College; The Statistical Team not only Dynamic

“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 they don't want to show the team’s work more than they talks. They are a ultimate ghost. No one know them but feels them so much by them’s works.

#LetGirlsMap for all boys YouthMappers chapter in Bangladesh

It is really a challenging part to work with female for all boys institute. And our society has conservative outlook of treating gender equally. But I believe in gender equality and it is the main key of every successful achievement. And I am decided to do that for the sustainable community.

Challenges: we have faced

Ensure a safe environment

In an under developing country it is a very crucial part is that every woman is concerned about the safe environment for her. So we have to ensure them that the mapping platform is a safe environment to the female.

Mapping tools training
Conservative society

It is the general issue for the under developing country specially in the muslim society. Our society has conservative outlook of treating gender equally.

Women are not exposed to these technologies in other fields of study

In our country it is another problem that woman is continuing her studies in any university they are not exposed to these technology is other fields of study.

Solutions: what we do

Clear vision of benefits of participation

First of all it is a solution that motivate the female to the participation in OpenStreetMap. If she has a clear vision of the benefits of participation then she motive herself to work with OpenStreetMap.

Remote Training
Ensure a safe environment

Ensuring a safe environment for the female we have to collaborate with local community, society club or educational institutes. As well as teachers, parents and POC of society.

All voices should be heard

In the conservative society has conservative outlook of treating gender equally. They always dominate female and never took any decision from them. But we believe in gender equality and it is the main key of every successful achievement.

Sustainable and effective plan

To make your sustainability efforts more efficient and effective. A plan is important because it focuses on the set of steps you will need to go through to achieve your ultimate goal, in this case an initiative with lasting impact. A planned effort will almost always be superior to an unplanned, disorganized attempt.

Passion and Dedication

The passion and dedication is one of the most dominant and persistent characteristics of human nature to achieve any untouchable goal. It is the main key to any success.

Collaboration with local communities

Collaboration is the main key to sustain a group or chapter. We can find all the energetic person from the local communities. They are reliable for the local entity. If we don’t collaborate with Local communities we can’t get any resource persons for the team and we can’t exist in the community.

As a result we have got more than 200 female mappers in our community in the last few years with some top contributors they are ranked  (5th, 11th and 49th) on the missingmaps global leaderboard.
