We encourage you to set your network projection to ensure that its location on the map is accurate.
Qatium locates your network in different ways, depending on the type of files you upload and the information they include.
Here’s how it works for each type of file:
EPANET .inp files
| Type of file | Projection included? | What Qatium does |
|---|---|---|
| EPANET .inp | No | Helps you select the most accurate option |
| Yes |
Reads variable: Q_VAR_PROJECTION: .crs info For example: EPSG:4326 OR Q_VAR_PROJECTION: .prj info For example: +proj=tmerc +lat_0=0+lon_0=0 +k_0=1 +x_0=0 +y_0=0 +units=m |
Right after the import is complete, if your .inp doesn’t include a projection Q will guide you to find the most suitable one.
- Find your network location on the map
- Q will suggest different projection candidates
- Select the most accurate one and click Ok
GIS files
| Type of file | Projection included? | What Qatium does |
|---|---|---|
| Shapefiles | No | Ignores the layer |
| Yes | Reads .prj file information | |
| GeoJSON | No | Assumes GeoJSON canonical projection (WGS84 / EPSG:4326) |
| Yes | Reads the projection declared |
Both .inp + GIS files
| Type of file | Projection included? | What Qatium does |
|---|---|---|
| .inp + GIS | Yes - .inp Yes - GIS |
Reads the projection declared in each file type |
|
No - .inp Yes - GIS |
Tries to use the GIS projection if it matches | |
| If GIS is a Shapefile |
Reads .prj file information |
|
| If GIS is a GeoJSON | Reads the projection declared |
Change projection
If your network seems misplaced, you can always change the location of your network.
