How to prepare your GIS data for upload
For Qatium to be able to run the simulation for your network, you need to prepare your GIS dataset including the following information:
| GIS layer asset types | GIS layer feature type | |
|---|---|---|
| Required | Pipes | LineString, MultiLineString |
| Highly recommended | Supply sources | Point, MultiPoint |
| Highly recommended | Tanks | Point, MultiPoint |
| Highly recommended | Pumps | Point, MultiPoint |
| Highly recommended | Valves | Point, MultiPoint |
| Highly recommended | Zones | Polygon, MultiPolygon |
| Highly recommended | Junctions | Point, MultiPoint |
| Ideal | Hydrants | Point, MultiPoint |
| Ideal | Customer points | Point, MultiPoint |
You can use the table below to see what information to include for each asset—categorized as highly recommended, recommended, or optional.
For more details, check out our full guide on how to define properties for each network element.
| Pipes | Junctions | Supply sources | Tanks | Pumps | Valves | Zones | |
|---|---|---|---|---|---|---|---|
| Highly recommended | Zone ID | ||||||
| Diameter | Group: hydrants / customer points | Head | Height | Power | Type | Inlets & outlets | |
| Roughness & headloss equation | Head pattern | Diameter | Operating curve (head curve) | Diameter | Demands | ||
| Orientation | Minor loss | ||||||
| Orientation | |||||||
| Recommended | Status | Demands | Elevation | Elevation | Status | Setting | |
| Controls | Elevation | Water age (to monitor water quality) | Overflow | Controls | Status | ||
| Thresholds | Thresholds | Initial level | Elevation | Elevation | |||
| Material | Water age (to monitor water quality) | Maximum level | Relative speed | Controls | |||
| Installation date | Minimum level | ||||||
| Maximum volume | |||||||
| Minimum volume | |||||||
| Thresholds | |||||||
| Water age (to monitor water quality) | |||||||
| Optional | Minor loss | Emitter coefficient (for Estimated leakage) | |||||
| Lenght | |||||||
| Group: Lateral | |||||||
Once your GIS data is ready, you can upload it into Qatium to create a network and/or start running simulations.
- Gather all your layers (Shapefiles—.shp, .shx, .dbf— and/or GeoJSONs) or zip them into a single folder.
- Browse your files or drag & drop them directly into the interface.
⚠️ Important:
- Before uploading your files, please make sure all of the network elements are connected to a supply source or a tank.
- If you do not have Shapefiles or GeoJSONs, you can use a software such as QGis, ArcGis or similar to export your data in the file types supported by Qatium.
