Find the right data for your question
Search for a place or topic, then narrow the results using the available filters. Open a resource to read its abstract, coverage, dates and permissions before downloading.
Find a datasetPut the data in context
Open a saved map to explore its layers. Zoom to an area of interest, adjust visibility and inspect the features. Available viewer tools help you compare layers and prepare map figures.
Explore mapsShare your work with others
Create an account and use the upload tools available to your role. Add a clear title, abstract, source, dates and licence, and set the appropriate access permissions.
Create an accountUnderstand the checks behind the data
Review the verification status, quality rating and metadata completeness on a dataset record. Verification is a useful signal, but always check whether the coverage, date and accuracy suit your purpose.
Understand data qualityGive credit and keep the source traceable
Use the citation tool on the resource page. Include the source, title, date and link in your work, and check the resource licence for attribution and reuse requirements.

From collection to use, in four stages
A shared workflow for data from university research projects, city authorities and community mapping exercises. Check each resource’s status to see where it is in the process.
01
Collect
Field surveys, satellite imagery and city records are gathered by universities, ministries and community mappers across Tanzania.
02
Publish
Contributors upload a layer with its metadata, thumbnail and licence, then assign it to a group and a risk theme.
03
Verify
CRD data managers review metadata, assign a quality rating and record the verification status.
04
Use
Find accessible data in the catalogue, explore it in the map viewer and download the available formats.

How you can tell whether a dataset is ready to use
Check the verification status, quality rating and metadata completeness on the dataset page. These help you assess a resource alongside its source, coverage and collection date.
Not verified
Published by a contributor but not yet checked by a data manager.
Under review
A data manager is reviewing the resource and its supporting information.
Verified
The resource has passed review. Check its scope and limitations before use.
Needs update
The record needs attention. Review the notes before relying on it.
Deprecated
Superseded or withdrawn. Kept for reference but not recommended for new work.
Quality rating
A reviewer’s assessment of the data’s quality. Read the review notes and supporting metadata to understand its suitability for your analysis.
Illustrative rating — check the individual dataset for its assessment.Metadata completeness
An automatic score indicating how much of the resource record has been filled in. A complete record helps you understand and reuse the data.

Is the data free to use?
You can browse public resources without an account. Download access and reuse terms depend on the resource’s permissions and licence. Check the licence on the dataset page before adapting or redistributing it.
Who can contribute data?
Registered contributors can upload data when their account has the required permissions. Include the source, collection method, dates, licence and contact details. Contact the CRD team if you need help with access or an institutional group.
How do I cite a dataset in my work?
Open the dataset page and use its citation tool. Check the author or organisation, title, publication date and link, then include the citation in your report or publication. Follow any additional attribution terms in the licence.
How often is the data updated?
Update schedules vary by source and dataset. Check the dates, maintenance information and verification notes on the resource page. Contact the owner if you need to confirm whether a newer version exists.
What formats can I download?
Available formats depend on the resource type and download permissions. Open the resource’s download menu to see its supported formats. Vector, raster and document resources offer different options.
Can I use CRD data offline or in QGIS?
Yes, when a resource allows downloads, save a supported format and open it in QGIS or another compatible application. Available web service links can also connect desktop GIS tools to online layers. Check the licence before reusing the data.
Still not sure where to start?
The CRD team can help you find the right data for your project and point you towards training for city authorities, universities and community groups.
