Data Intelligence Lab
WaterScape Data Intelligence Lab
See how water information moves from a raw record to a cautious, explained insight. Every step shows its limits, and nothing here connects to outside systems.
Simulated data processing. No external system is connected or transmitting data.
The eight stages
Stage 1 of 8: Source discovery
What happens
Identify where candidate data could come from, such as public registers, community reports or partner files. Note who owns each one and what licence or permission applies.
Why it matters
Good analysis starts with knowing where data came from and whether it may be used for this purpose.
Limits
Finding a dataset does not give permission to use it. Licences, consent and privacy rules come first.
Run the sample exercise
SimulatedChoose an invented dataset, inspect its raw records, then start a run and watch each of the eight stages activate in turn. Nothing is sent anywhere.
Dataset
Contains missing fields, a bad latitude, a duplicate, mixed dates, conflicts, unit traps and missing attribution.
Provenance of this dataset
- Sample status
- Invented sample data. Not real measurements.
- Source description
- Written by the WaterScape team for this demonstration. 10 records.
- Limitations
- Deliberately contains errors for teaching. Places, coordinates and prices do not describe any real water source.
- Dataset snapshot / processing date
- Snapshot 6 Nov 2026, 08:30 UTC. Not processed yet.

Check your own data file
Check a file for structure, missing fields and possible duplicates. The checker flags problems for human review. It does not correct, delete or invent values, and passing the checks does not show that the data is true or current.
Nothing is uploaded. Your file is read in this browser, on your device. It is not sent to WaterScape or any other server. Files over 500 KB are refused.
Expected fields: name, category, lat, lng, date, source. In a CSV, the first row names the columns. In JSON, use a list of records or an object with a "records" list.
Source profile and provenance
Before you rely on a dataset, answer these five questions. A blank answer is a reason for caution, not a finding.

0 of 5 questions answered
Name the place, register, survey or person the record came from.
Give the date or period of the observation, not the date it was uploaded.
Name the contributor or organisation, or say that it is anonymous.
Describe the method, such as a visual check, a survey, a meter reading or a report form.
Note any cleaning, unit conversion, removed records or estimates.
