    InfoWater SA - Full Extent View

    Good Day
    After upgrading from H2Omap Water to Infowater Stand Alone and importing old H2OMap files, the icon Full Extent icon in Infowater is no longer functioning as it did in H2OMap. Can you please advise on this issue.

    Also when I try to set my Spatial Reference limited to certain functions (some function greyed out ). Is this a limitation of InfoWater Stand Alone version
    Create Project.PNG

    Natalie,

    What is likely happening with the full extent is due to how ArcGIS expands full extent to include the entire viewing area which can at times cause issues with being way to big for your model only area as this tends to be the ESRI default setting. If you used the default projection the full drawing area (the entire world essentially) would generally be set as full extent by the ArcGIS engine.

    While one can easily adjust this in regular InfoWater to limit the view shown by full extent, this option is not available in InfoWater SA due to restrictions associated with the ArcEngine used by InfoWater SA.

    However, if you send us your model .MXD file and .IWDB folder zipped to a single file, we can send it back to you with the full extent adjusted to the area around the model and this can be read by InfoWater SA and should easily resolve your difficulties.

    Please send this file to support@innovyze.com and please add a note requesting the full extent be adjusted to the model limits and that you be sent back the .MXD file in ArcGIS 10.5 format with the full extend defined as requested. You would simply need to replace your old .mxd file with the fiel we would send back.

    Adjusting spatial projections in InfoWater SA is slightly different than InfoWater, but as your model in H20MAP Water was not assigned a spatial projection you may need to try a few projections to verify what the old model was built in. Once you select the correct projection when you add a free ESRI basemap your model will line up to the imagery and streets as expected as long as your model was built in proper coordinates. If your model was built generic coordinates it may not line up properly with any projection.

    The easiest way to change spatial projections in InfoWater SA is generally to use the following procedure:
    (click if need a larger image)
    set spatial projection in InfoWater SA.jpg


    ​Key Excerpt from the image: The easiest way to assign a Spatial Projection in InfoWater SA is to know the WKID (what is often called EPSG) of the projection you wish to use. You can usually find this by a quick google search which your utility GIS staff would likely be able to assist you in finding.
    i. Example: For GDA94 / MGA zone 55 the EPSG code (and thus the WKID) was found on this page as 28355 http://spatialreference.org/ref/epsg/gda94-mga-zone-55/ This is the code that needs to be entered to define the projection.
    ii. Once you know this code enter it in in the search line and it will select the projection you want in the list.

    Due to limitations in the listing you may not see all projections you can use without identifying this number beforehand. But if you give it a specific WKID it should find any projection defined in the ArcGIS 10.5 engine.

    Please feel free to respond to this message if you have any remaining questions.
