Who we are

As our name suggests, we are a group of Bangladesh-based mapmakers

GroupMappers is a Bangladeshi crowdsourcing initiative that utilizes geospatial technology for public health issues. Established in 2017, it is led by the Mahidol Oxford Tropical Medicine Research Unit and the Communicable Disease Control division of the DGHS in Bangladesh.

The organization’s 20 core members possess a strong GIS aptitude and diverse backgrounds in education and professional experience. Starting with village mapping, our success in the field has continued to grow.


“Empowering communities through the utilization of crowdsourced mapping and data analysis for enhanced public health outcomes.”

What we do

By utilizing a geospatial approach, we aim to address public health issues through the development of innovative solutions. This approach involves using geographical data and technologies, such as mapping and spatial analysis, to gain a better understanding of the distribution and spread of diseases, identify high-risk areas, and evaluate the effectiveness of different interventions.

By using this approach, we can improve the targeting and delivery of public health interventions and ultimately improve the health outcomes of affected communities.

We have expertise in data processing, and database design and development. This involves activities like data cleaning, quality control, and data transformation for ensuring accuracy and consistency in geospatial data.

At GroupMappers, spatial analysis and modeling are integral to our work, particularly in physical accessibility analysis. Our experience includes utilizing geospatial data to perform spatial interpolation, overlay analysis, and spatial statistics, among other techniques. These capabilities enable us to support public health initiatives by providing data-driven insights and recommendations.

GroupMappers specializes in creating interactive web maps and visualizations that communicate geospatial information to end-users. Our experience includes developing web mapping applications, creating custom map styles, and integrating with other data sources to present spatial data effectively. We have utilized these skills in various public health projects to improve understanding and decision-making in the field.

GroupMappers provides support in making geospatial data accessible to stakeholders and end-users. This support includes activities like data publishing, sharing, and implementation of data access policies. Through these efforts, GroupMappers aims to facilitate the effective use of geospatial data in public health and related domains.

Volunteerism and Support

As a crowdsourcing initiative, GroupMappers values the power of volunteerism and engages young individuals who share a passion for exploring the world of geospatial techniques and public health. This provides an opportunity for individuals to participate in action-oriented and impactful activities.

Volunteers can choose to participate in segments that align with their interests, such as working for fund raising , mapping, writing for newsletters or conducting sessions in GIS/RS club cafes.
