Qatium locates your network in different ways, depending on the type of files you upload and the information they include. We encourage you to set your network projection to ensure that its location on the map is accurate.
Here’s how it works for each type of file:
EPANET .inp files
| Type of file | Projection included | What Qatium does |
|---|---|---|
EPANET (.inp) |
No |
Q helps you select the most accurate option |
Yes |
Reads variable: Q_VAR_PROJECTION: crs info For example: EPSG:4326 or ESRI:32059 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 upload 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
- Select the most accurate projection candidate from Q suggestions
- Click Ok
