What's new in WMS 9.1

The following is a list of the more significant changes in WMS 9.1

  1. Support of new GIS and CAD file formats for import and export
    • Add GIS Data Command
      • The Add GIS Data command in the Get Data toolbar allows you to read many formats of vector and raster GIS data. After reading the data, it can be viewed or converted to a format that can be used for hydrologic modeling in WMS.

    • Raster Display Options
      • If you have read raster elevation data using the Add GIS Data command or if you have online data that contains raster elevations, there are various options for displaying hill shading on the raster data. You can also convert any raster elevation data to a DEM.
        Raster Display Options
    • GIS Vector Data Conversions
      • GIS Vector Data can be converted to a shapefile. Once your GIS data are converted to a shapefile, they can be used in any of the hydrologic modeling computations for tasks like computing curve numbers and infiltration coefficients.

    • Raster Data Conversions
      • Raster Data ConversionsRaster data with information about land use or soil type can be converted to a land use or soil type grid by right-clicking on the layer. USGS NLCD and European CORINE Land use data can also be downloaded for anywhere in the United States and Europe using the Get Data tool. More information about the new data sources available in WMS 9.1 can be viewed here.
        WMS DEMs can be exported to several digital elevation file formats, including the following:
        • GeoTiff
        • BIL
        • ERDAS Imaging IMG
        • Surfer ASCII Grid
        • Surfer Binary Grid
        • USGS ASCII DEM
        • XYZ ASCII Grid
        • ArcInfo ASCII Grid
        • DXF 3D Point
        • Float/Grid
        • DTED
        • MapInfo Grid
        • GlobalMapper Grid
        • Windsim GWS
        All these files as well as many other formats can also be imported using the Add GIS Data button.
    • Vector/Shapefile Data Conversions
      • Raster Data ConversionsVector GIS data that is read into WMS can be converted to a shapefile and used in WMS or saved to one of the many other supported formats. The supported formats include:
        • DXF Files (*.dxf)
        • Area Shapefiles (*.shp)
        • Line Shapefiles (*.shp)
        • Point Shapefiles (*.shp)
        • Google Earth KMZ Files (*.kmz)
        • MapInfo MIF/MID Files (*.mif)
        • MapInfo TAB/MAP Files (*.map)
        • Simple ASCII Text Files (*.txt)
        • CSV (Comma-separated value) Files (*.csv)
        • SVG Files (*.svg)
    • GIS Module
      • All /images, raster GIS data, and vector GIS data are now stored in the GIS module. In the GIS module, you can import, export, and convert GIS data to different formats. You can also map data in the GIS module to data in WMS that can be used to build your watershed models.
    • TIN Elevations from LandXML Files
      • WMS 9.1 allows you to read LandXML files as a TIN. This command to import LandXML files preserves your points and the triangle connections that were built in the CAD program that was used to generate the LandXML file.

    • DGN, DWG and other CAD File Support
      • WMS 9.1 supports most of the latest DGN, DWG, and DXF file formats through the Teigha library. Currently, WMS 9.1 uses version 3.05.01 of the Teigha library.
  2. Multiple DEMs
    • WMS 9.1 allows you to read and manage multiple DEMs in the project explorer. Each of these DEMs can have flow directions and accumulations for watershed delineation. You can clip and modify single DEMs or merge multiple DEMs from different sources into a single DEM. You can convert raster elevation data in the GIS module to DEMs. These DEMs can be merged and exported to any of the raster elevation formats supported by WMS.

  3. Improved web services (online data) tools
    • Improved Web Services (Online Data) ToolsWMS 9.1 has three tools for obtaining online data: The Get Data tool, the Get Data From Map command, and the Get Online Maps command. All of these tools can be used to obtain various types of raster data: /images, elevation data, land use data, vegetation data, and more.
      • Get Data
        The Get Data tool and the Get Data From Map command work in much the same way. You need to set your current projection before using either of these tools. The difference is that with the Get Data tool, you select the area where data is desired from your WMS window. With the Get Data From Map command, you select the area from the Virtual Earth Map Locator window. This Virtual Earth window pops up after selecting the Get Data From Map command. In either case, you go to the area you are interested in and WMS will bring up another window that allows you to select the type of data you would like to download. With all the raster data sources, you specify a resolution of the data you want to download and WMS will download the data.
        Several new data sources have been added to the Get Data tools in WMS, including various sources for high-quality imagery. Samples of many of the data sources are shown in the new Get Data dialog.

      • Got Online Maps
        The Get Online Maps command allows you to define online data sources you want added to your display. This command was introduced in WMS 9.0, and has been improved in WMS 9.1. WMS 9.1 launches a separate process to download the online data when it is downloading so you no longer need to wait for your data to download before working. WMS 9.1 also has tools to convert your online data to static data and to convert it to various formats that can be used for watershed modeling.
  4. Texture mapping on TINs
    • The capability to texture map /images to TINs has been added. This capability allows you to read or download an image using the Get Data tools and then texture map the image on a TIN. This gives you the option to create a nice image of your watershed model and to visualize the locations and terrain surrounding hydraulic structures in your watershed. You can also use the texture mapping capabilities to view flood locations and contours from a HEC-RAS analysis.

  5. Model Improvements
    • GSSHA Snowmelt
      Several options to support the GSSHA snowmelt models have been added to the WMS interface. When running long-term GSSHA simulations, the GSSHA snowmelt parameters can be modified in the easy-to-use WMS interface. WMS 9.1 also has options to define raster HMET files for use in GSSHA long term simulations.

    • HEC-RAS Water Surface Elevations
      If you have an existing HEC-RAS model and want to bring it into WMS, there has not previously been a way to read the water surface elevations from the HEC-RAS solution. Now if you export your water surface elevations with the GIS file that's exported from HEC-RAS, WMS reads these water elevations.
    • SWMM Attributes
      If the correct attributes have been assigned to arcs in a shapefile, WMS now imports storm drain attributes such as names, shapes, diameters, lengths, and upstream and downstream invert elevations to your SWMM model in WMS. This makes your SWMM modeling easier because you don't have to re-enter the pipe attributes that are already defined in a shapefile.

The following is a list of the more significant changes in WMS 9.0

  1. Online Image (Web Map Service) Capabilities
    • One of the most exciting new features in WMS is the Get Online Maps tool in the Get Data Toolbar . This tool allows you to open a web map service as an "online image" and use it as you would any other image in the WMS interface. Since the web can be a little slow, there is an option to convert the online image to a static (locally saved) image that is saved with your WMS project which displays much faster than the online image.
  2. Updated Interfaces
    • NSS (National Streamflow Statistics) interface: Has been updated to use the latest NSS database
    • MODRAT interface: Renumbering has been improved in the MODRAT interface and several issues have been fixed.
    • GSSHA interface: The storm and tile drain modeling capability of GSSHA has been improved by adding the capability to add multiple pipes in a "superlink", which represents a network of pipes in GSSHA. The algorithm for determining embankments has also been reworked to make the algorithm more efficient and more accurate. The GSSHA tutorials have been updated and improved to include the latest enhancements in the GSSHA code, and GSSHA itself has been reworked to make the program more stable.
  3. FHWA HY-12 Strom Drain Modeling
    • WMS now includes an interface to FHWA's HY-12 storm drain modeling program. This interface allows you to create a storm drain layout and assign rational method computations, curbs and gutters, access holes, pipes, channels, and other storm drain network features to the storm drain layout. Much of the data can be computed automatically using the interface, and other data values can be entered in the easy-to-use windows. The other storm drain modeling interfaces, including the SWMM and xp-swmm interfaces, have also been upgraded to make your model easier to build and maintain.
  4. Improved Web Service Tools
    • Six new web services have been added to the list of web data that can be downloaded from the WMS Get Data Toolbar. These web services include some that were previously available, such as United States National Elevation Datasets, as well as newly available datasets, such as the CORINE European land cover database, the NLCD US National Land Cover database, and the ASTER Worldwide Elevation Data database. These new datasets are much faster than previously available datasets and include a progress bar so you can view the progress of your data download.
  5. Support of New File Formats
    • We have added support for almost all the commonly used vector file formats in the new version of WMS. Some vector files, such as DXF, DWG, and ESRI Shapefile format, still read the way they have always read into WMS. But support for "Vector-based /images" has been added to WMS that allows you to read any file that can be read using the Global Mapper software in WMS (A license to Global Mapper is not required). For a complete listing of the vector formats supported in WMS, visit the Global Mapper web site. Right-clicking on a vector image allows you to export to one of many formats or convert linear data to feature objects or scattered data (XYZ). The following formats can be exported using the right-click command:
      • DXF Files (*.dxf)
      • Area Shapefiles (*.shp)
      • Line Shapefiles (*.shp)
      • Point Shapefiles (*.shp)
      • Google Earth KMZ Files (*.kmz)
      • MapInfo MIF/MID Files (*.mif)
      • MapInfo TAB/MAP Files (*.map)
      • Simple ASCII Text Files (*.txt)
      • CSV (Comma-separated value) Files (*.csv)
      • SVG Files (*.svg)
  6. FHWA HY-8 7.3 and Hydraulic Toolbox 3.0 Support
    • The FHWA's HY-8 7.3, which includes many new culvert modeling capabilities, is supported in the new version of WMS including modeling of hydraulic jump profiles, broken back culverts (culverts with a change in slope), and horizontal and adverse slopes in culverts. Documentation showing the capabilities included in the latest version of HY-8 is included on the HY-8 wiki. The new version of the FHWA's Hydraulic Toolbox (3.0) is also supported with the new version of WMS which includes tools for culvert assessment and for determining a riprap or streambed gradation curve using a digital image.
