A WaterGEMS model can be uploaded into WaterSight, by acceding the Admin >> Numerical model page.

When uploading a WaterGEMS model it is required to define the EPSG code in order to have it displayed in the correct position in the map. In most cases, the EPSG code or a description of the coordinate system can be found by examining the layer properties in any GIS software. Note that each layer may have different coordinate systems if the utility has not standardized to a single system. EPSG codes can be found by searching https://spatialreference.org/. 

In case there is:

• an error during the model upload process or
• the model is shown in the wrong position or
• when accessing the map page a black screen is shown instead or
• the model is based on an ESRI code (instead of EPSG code)

First solution is to try to find /get an equivalent EPSG code that works without reprojection. In most cases there is an alternative available. For example:

• EPSG:7856 = GDA2020 / MGA Zone 56
• EPSG:28356 = GDA94 / MGA Zone 56

In case this does not work, the user has also the possibility to define the WKT (well-known-text) for that specific EPSG / ESRI code that is not supported. To find for the WKT related with the EPSG or ESRI, please follow the below steps:

• go to https://spatialreference.org/
• on the top right search for the EPSG/Esri code
• Click on the entry found
• Click on the WKT1 row or Esri WKT (see below)

• Copy -paste the text to WaterSight (see below)

• Choose a WaterGEMS model (Sqlite or Zip) and click Upload

After defining the WKT, to change it again the user will need to reupload again a hydraulic model.
