The following is a list of the more significant changes and new features available in WMS 11.0.

LIDAR Management

WMS 11.0 now supports advanced LIDAR data handling tools for reading, viewing, and converting LIDAR data to other formats for use with your model. Large LIDAR datasets are efficiently displayed with options to specify the number of points visualized and exclude points outside the extent. WMS 11.0 supports LIDAR data in both Point Cloud and Elevation grid formats and supports converting Point Clouds to Elevation grids.

HEC-RAS and HEC-HMS Updates

The most recent versions of HEC-RAS (v5.0.3) and HEC-HMS (v4.2.1) are now supported in WMS 11.0. Importing HEC-RAS GIS (*.sdf) files is now faster and easier to use. Managing and editing cross section databases for HEC-RAS is now easier in WMS. A new dialog is available for selecting, managing, and editing cross sections and cross section databases.

New Map Flood Tool & Floodplain Delineation

A new map flood tool is available to define a vertical offset from a 100-year floodplain map for analyzing extreme flood scenarios. Modified floodplain maps can be used to determine the impacts of extreme weather and flood scenarios on existing and proposed roadways and other structures. Floodplain delineation in WMS 11.0 is now streamlined and much faster than in previous versions - in many cases by a factor of 10.

Worldwide Elevation Data

WMS now supports Amazon Terrain Tiles providing high resolution elevation data for the entire world with resolutions as high as 3 meters per pixel.

LandXML Import & Export

Support for reading and writing LandXML files from the hydraulic modeling module for the SWMM, HY12, and EPANET models has been added.

Graphics Enhancements

High resolution displays caused icons and text in older versions of WMS to render very small. WMS now detects your display resolution and appropriately sizes icon bitmaps and fonts. Icons may also be sized manually in the Preferences dialog. Additionally, a multisampling level tool has been added for adjusting the anti-aliasing of graphics.
