Crowdsourced Mapping Platforms

TrashOut https://www.trashout.ngo/


TrashOut is a global, crowdsourced environmental project aimed at identifying and 
mapping illegal waste dumps worldwide. The project was developed as a mobile and 
web application, allowing users to report and locate illegal dumping sites, 
contributing to a cleaner and more sustainable environment. TrashOut encourages 
individuals to become environmental stewards by actively participating in waste 
monitoring and removal efforts.


Key Features of the TrashOut Project:

1. Crowdsourced Mapping of Illegal Dumps: TrashOut relies on its users to 
report illegal waste dumps. By using the mobile app, people can take photos of 
dumpsites they encounter, provide a description, and submit their reports. 
These reports are then mapped in real-time on an interactive platform that 
anyone can access to view illegal waste dump locations.
2. Global Coverage: TrashOut has a global reach, with users from all over the 
world contributing to the map. Although coverage and accuracy may vary 
depending on the region, it offers an open, citizen-driven solution to monitor 
waste in urban and remote areas.
3. Data for Governments and Organizations: TrashOut’s data can be shared 
with local governments, NGOs, and environmental organizations to help 
inform waste management policies and cleanup initiatives. Municipalities can 
use the data to plan cleanup operations, identify hotspots for illegal dumping, 
and improve waste disposal systems.
4. Offline Reporting: The app allows users to report illegal dumps even when 
they don’t have internet access. Users can save the report and upload it once 
they are back online. This feature is particularly useful for tracking dumps in 
remote areas where connectivity may be limited.
5. User-Friendly Interface: TrashOut’s mobile app is designed to be intuitive 
and easy to use, making it accessible to anyone. Users simply:
• Open the app,
• Pinpoint the location of the dump on the map,
• Provide details like the type of waste and the size of the dump,
• Upload a photo, and
• Submit the report.
6. Educational and Awareness Tool: In addition to reporting dumpsites, 
TrashOut aims to raise awareness about illegal dumping and waste 
management issues. The platform provides educational materials and 
encourages communities to take action against waste pollution by organizing 
local cleanups.
7. Partnerships and Support: TrashOut collaborates with various partners, 
including governments, municipalities, NGOs, and environmental 
organizations, to use its data for organizing waste collection efforts and 
promoting sustainable waste management practices. This makes the platform 
an important tool for cities and regions with limited resources for monitoring 
illegal dumping.
8. Progress Tracking and Follow-Up: Once a dump site is reported, users and 
authorities can track the status of the site. After the site is cleaned up, the status
can be updated to reflect that the dump has been removed. This follow-up 
process ensures that the platform provides up-to-date and actionable 
information.
9. Environmental and Social Impact: By involving communities in reporting 
illegal dumping, TrashOut empowers citizens to take responsibility for their 
local environment. This contributes not only to cleaner public spaces but also 
to broader goals of reducing pollution, protecting wildlife, and preventing 
hazardous waste from contaminating ecosystems.


How TrashOut Can Be Used:

1. For Citizens: Individuals can use TrashOut to easily report illegal dumps in 
their neighborhoods. The app helps bring attention to waste problems and 
encourages people to be proactive in cleaning up their communities.
2. For Governments and Municipalities: Local authorities can use the data 
collected via TrashOut to identify problem areas, plan waste management 
interventions, and engage with communities to prevent future dumping.
3. For Environmental NGOs: NGOs working on waste management and 
pollution control can leverage TrashOut’s data to inform their campaigns and 
organize cleanups in high-priority areas. They can also use the platform to 
promote community engagement in tackling waste-related issues.
4. For Businesses: Companies involved in waste collection, recycling, or 
environmental consulting can use the data to identify potential clients, locate 
problematic areas, and offer solutions for waste reduction.
Successes and Impact:
• Global Adoption: TrashOut has seen participation from users worldwide, 
particularly in Europe, Africa, and Latin America. By allowing people to easily
report illegal dumps, the platform has created a vast database of dumpsites that 
can help authorities prioritize cleanup efforts.
• Awareness and Cleanup Campaigns: The app has been used to support large
scale cleanup campaigns, often organized in collaboration with local 
governments or environmental organizations. TrashOut helps to document 
these efforts and ensure the areas remain clean.
Challenges:
• Data Accuracy: Since the platform relies on crowdsourced data, the accuracy 
and completeness of reports may vary. In some regions, fewer users may result 
in underreporting, while in others, dumpsites may be miscategorized.
• Reliance on User Engagement: The success of the platform depends heavily 
on active user participation. Without regular updates and user contributions, 
dumpsites may go unnoticed, or cleaned areas may not be reflected on the map.


Litterati https://www.litterati.org/


Litterati is a global environmental initiative that empowers individuals to document 
and map litter using a mobile app. The project focuses on addressing littering by 
collecting data on the type, location, and brand of trash found in public spaces. By 
using crowdsourced data and AI-driven analytics, Litterati aims to tackle global 
waste and help municipalities, companies, and communities develop better waste 
management and cleanup strategies.


Key Features of the Litterati Project:

1. Crowdsourced Litter Data Collection: Litterati’s core functionality allows 
users to take photos of litter and upload them to the platform, creating a 
database of litter around the world. Each photo captures the location, type, 
and brand of the litter, allowing for detailed analysis.
2. Global Participation: Litterati has users across the globe, making it one of the 
largest datasets on litter in existence. Participants range from individuals and 
community groups to schools, governments, and large corporations. The app 
has logged millions of pieces of litter from all corners of the world.
3. Data Analytics for Litter Mapping: The platform uses artificial intelligence 
(AI) to categorize the types of litter and track where they are most commonly 
found. The data helps identify patterns in littering behavior, such as:
• Which locations are most affected,
• The most common types of litter (e.g., plastic, paper, cigarette butts),
• The brands associated with the litter (important for accountability).
4. Challenges and Competitions: Litterati engages communities by organizing 
challenges and competitions to clean up specific areas or reduce certain types 
of litter. Schools, cities, or organizations can set goals and track their progress 
over time. These challenges often involve friendly competitions to see who can
collect and document the most litter.
5. Geo-Tagging for Location Tracking: Every piece of litter documented with 
Litterati is geo-tagged, meaning it is tied to a specific location. This allows 
users and municipalities to view litter hotspots on a map, providing valuable 
insight for cleanup efforts and waste management planning.
6. Litter Insights for Cities and Governments: Litterati offers detailed insights 
and reports to local governments and municipalities based on the collected 
data. This data-driven approach helps authorities to:
• Identify litter-prone areas and focus cleanup efforts,
• Understand the impact of existing litter policies and regulations,
• Promote recycling and waste reduction strategies based on real-world 
data.
7. Brand Accountability: One unique aspect of Litterati is its ability to track the 
brands most commonly found in litter. This helps hold companies accountable 
for the environmental impact of their packaging. The data can also be used by 
businesses to improve their sustainability practices by reducing single-use 
packaging or adopting circular economy principles.
8. Educational and Community Engagement: Litterati is often used by schools,
universities, and community groups as an educational tool to teach students 
about environmental responsibility and the importance of keeping public 
spaces clean. It encourages communities to take action and become more aware
of waste management issues.
9. Environmental Policy Advocacy: The data generated by Litterati can be used 
by environmental organizations and activists to advocate for better waste 
management policies, including bans on single-use plastics or improvements in
public recycling infrastructure.


Use Cases for Litterati:

placement or recycling programs).
• Create public awareness campaigns using real-time data about local 
littering behaviors.
2. For Schools and Educational Institutions: Schools often integrate Litterati 
into environmental education programs. By encouraging students to 
participate in litter challenges, educators can teach important lessons about 
waste reduction, sustainability, and personal responsibility.
3. For Businesses and Brands: Companies can use Litterati to:
• Analyze how often their packaging is found as litter and where it is most 
commonly disposed of improperly.
• Take steps to redesign packaging to be more sustainable or to educate 
customers about proper disposal.
• Demonstrate corporate social responsibility by using the data to reduce 
their environmental footprint.
4. For Environmental NGOs: Non-governmental organizations (NGOs) can use 
Litterati’s data for advocacy campaigns, pushing for stronger environmental 
protections and better waste management practices at the local and national 
levels. The data can also be used to organize large-scale cleanups and track 
their impact.
5. For Individual Users: Anyone can participate by documenting litter in their 
neighborhood or community, contributing to the broader goal of reducing 
waste and keeping public spaces clean.
Success and Impact:
• Millions of Pieces of Litter Documented: Since its inception, Litterati has 
grown to include a vast number of users who have collectively documented 
millions of pieces of litter worldwide. This has made it one of the most 
comprehensive datasets for tracking and understanding littering behavior 
globally.
• Policy Changes: Litterati’s data has contributed to policy changes in several 
cities, including influencing the placement of trash and recycling bins, and 
even supporting the passage of bans on single-use plastics in some regions.
• Brand Accountability: Some companies have used Litterati’s insights to 
rethink their product packaging and invest in more sustainable materials.
Limitations:
• User Participation: The effectiveness of Litterati relies on active user 
participation. Areas with fewer users may have less data, and hotspots might be
underreported in less-populated regions.
• Data Validation: Since the platform relies on crowdsourced data, there may be
inconsistencies in how users tag litter or identify brands
