Data Exchange in InfoSewer and H2OMap Sewer

Data Exchange in InfoSewer and H2OMap Sewer

InfoSewerH20Map Sewer has an extensive data exchange functionality. Using InfoSewerH20Map Sewer data exchange features one can import collection system maps and the associated data created by H2OMap Sewer; export collection system maps and the associated data created by InfoSewer into H2OMAP Sewer; import/export input data and simulation outputs from/to data formats that are compatible with GIS, CAD, CSV; export/import collection system geometry to/from ArcInfo generate files, and exchange model outputs with other applications including presentation applications, spreadsheets, and word processors.

Built with ESRI MapObjects and supporting numerous database, CADD, GIS, and data formats, H20Map Sewer supports many powerful GIS and mapping functions. Its unique open-architecture framework allows information to be easily exchanged with other applications including CAD and presentation applications, spreadsheets, and relational databases.

Although transparent to the user, H20Map Sewer is developed to run entirely within a standalone (i.e., no additional CADD or GIS software required) environment. H20Map Sewertools are accessed using customized MapObjects commands, menus, and toolboxes, and the graphical user interfaces for these tools are based exclusively on Windows interface standards.

InfoSewerH20Map Sewer supports the following data exchange functionality.

  • Import/Export Managers - Background mapping, external models or InfoSewerH20Map Sewerdata elements.
  • Import/Export Generate Files - Import generate files in to InfoSewerH20Map Sewer or export InfoSewerH20Map Sewerin to generate file.
  • Append Nodes - Allows the user to create a conduit and node network from third party software application like AutoCAD, Microstation, or ESRI shapefiles.
  • ODBC Exchange - Download and upload data to and from InfoSewerH20Map Sewerby creating data links.
  • GIS Gateway - Allows exchange of Geodatabase information to and from the model.
  • Windows Clipboards - Export and view model results outside of InfoSewerH20Map Sewer.
  • Import H2OMap Sewer - Import H2OMap Sewer Model into InfoSewerH20Map Sewer.
  • Export to H2OMAP Sewer - Export to H2OMAP Sewer

In addition to the data exchange features supported by InfoSewerH20Map Sewer, the following database connection and exchange features are available from ArcGIS.

Issues to Consider When Importing GIS data into InfoSewer

If you import data from a GIS you should ensure the following before importing into InfoSewerH20Map Sewer:

  • All conduits (arcs, lines) in the GIS are connected to two unique nodes.
  • All conduits in the GIS are snapped together where those conduits represent connected conduits in your sewer collection system. In other words, be sure that where two or more conduits should be connected, those conduits should share the same node in the GIS or other external database.
  • There are no disconnected nodes in the GIS database. Each node should be connected to at least one conduit in the GIS.
  • The graphical representation of the conduits in the GIS corresponds to the values in your database that represent the from- and to-node identifiers. In other words, if a conduit in your GIS database has a from-node value of “1” and a to-node value of “2”, then the graphical representation of that conduit on the map display shows that conduit starting at node “1” and ending at node “2”.


  • If you do not meet the above-listed criteria, you may experience one or more errors when running a simulation in InfoSewer. The two most common situations that may occur if you do not meet the above-listed criteria before importing are the following:
    • Isolated Node – One or more nodes are disconnected from the network.
    • Coincident Nodes – Two or more nodes share the same location, appearing to a viewer as a single node.
  • InfoSewer has tools that will help you correct these problems in the event that your GIS is too burdensome. From the InfoSewer Control Center -> InfoSewer button ->Utilities menu, point to Connectivity and select Orphan Nodes or Orphan conduits. By doing this, InfoSewer will identify which nodes are not connected to conduits and which conduits do not have both an upstream and downstream node.

The GIS Gateway is not part of H2OMap Sewer but is an integral part of InfoSewer
