WMS:What's new in WMS version 9.1

The WMS software development team is excited about the release of WMS 9.1! This page lists the exciting new features that have been added to WMS 9.1.

What's new in WMS 9.1

Support of new GIS and CAD File Formats for Import and Export

Add Data Command

The Add 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 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.

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 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, and 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

Vector 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.

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.

Improved Web Service (Online Data) Tools

Online Data Works Seamlessly (no waiting for the data to download)

Updated Get Data Dialog
