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:
| Level of importance | 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 |
Once you have your assets, the more information you include about them, the better insights you'll get. Here's what we recommend you to include for each asset type.
Highly recommended
| Pipes | Junctions | Supply sources | Tanks | Pumps | Valves | Zones |
| ID (Element Identifier) | ID (Element Identifier) | ID (Element Identifier) | ID (Element Identifier) | ID (Element Identifier) | ID (Element Identifier) | 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
| Pipes | Junctions | Supply sources | Tanks | Pumps | Valves |
| 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
| Pipes | Junctions |
| 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.
Heads up:
- 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.
