WaterPath Toolkit Data Schemas

At the core of the WaterPath Toolkit, data schemas are used to formally define the structure, types, and constraints of the input and output data involved in the developed tools. A data schema serves as a blueprint that ensures consistency, validation, and interoperability across components by specifying how data should be organized and interpreted. Data conforming to these schemas can be reliably parsed and consumed by the GloWPa model, resulting in robust results and minimized errors and inconsistencies.

All data schemas in the WaterPath Toolkit are defined using the Tableschema specification and expressed in JSON format. They are openly available on our Github repository.

The following data types are currently supported:

Population (population_schema.json)
Sanitation (sanitation_schema.json)
Treatment (treatment_high_resolution_schema.json OR treatment_schema.json)

Navigate the documented data properties by clicking on each schema below:


This schema defines the properties for the geographic area and its respective population, used for simulation purposes.
iso
string
An identifier for the tabular data row.
gid
string
The GID starts with the three letter ISO 3166-1 alpha-3 country code. If there are subdivisions these are identified by a number from 1 to n.
iso3
string
ISO-3166-2 code links to the countries referenced by the populatikon portion of the data.
subarea
string
Name of administrative area (country/subcountry region).
hdi
number
Human development index of admininistrative area
>= 0<= 1
population
number
Total population in administrative area used as reference for correcting gridded population data.
>= 0
fraction_urban_pop
number
Fraction of urban population in administrative area for correcting gridded population data
>= 0<= 1
fraction_pop_under5
number
Fraction population younger than 5 years.
>= 0<= 1
