RiverTools | 地形和河流网系提取及分析软件

RiverTools 软件是一个专业的地形和河流网系提取和分析软件,能快速从大数据量DEM中提取出河流排泄区的网络模型,对提取出的河流网络提供综合分析,并以专业图形方式显示和矢量输出,实现地形模型可视化, 提供二次开发函数。可用在地貌和水利分析、洪水淹没模拟、流域分析、防洪工程、灾情分析、水文站水位流量分析、堤岸建设、数字流域等应用领域。


RiverTools强大的地形和流域分析功能为水利研究和应用工程提供了有力的支持。RiverTools的下列特点使其非常适合在水利工程实际中使用:

 

• 支持海量DEM,提取速度快

• 精度高。DEM在处理前不需要将计算长度和面积转换为等积投影

• 更新更强的算法。

• 新增的提取菜单和淹没菜单提供了更强大的DEM处理功能s

• 强大的定性和定量分析功能,如面积-高度分析函数,洪水淹没分析等。

 

RiverTools软件综合功能强大,从开始到结束的一个流域分析、子流域和河流中的一小部分提供准确的测量和河流域上游地区等特点,通道长度,海拔下降,使用您选择的地球椭球模型的斜率和曲率。RiverTools软件便于划定流域边界和计算众多的流域和子流域参数。可以导入其他RiverTools软件GIS应用如ESRI的ArcView导出数据(通过支持BIL、外语、shapefile,GeoTIFF)和遥感,如ENVI图像处理系统(可视化图像环境)。                        



 

RiverTools 4.0 is a user-friendly GIS application for analysis and visualization of digital terrain, watersheds and river networks. One of RiverTools' most powerful features is its ability to rapidly extract drainage network patterns and analyze hydrologic data from very large DEMs (digital elevation models). With RiverTools you can perform a comprehensive, start-to-finish analysis of a watershed, sub-basin and river network in a fraction of the time it would take with less-specialized GIS software. RiverTools provides accurate measurement of river and basin characteristics such as upstream area, channel lengths, elevation drops, slope and curvature using the Earth ellipsoid model of your choice. RiverTools makes it easy to delineate catchment boundaries and calculate numerous basin and sub-basin parameters. RiverTools can import and export data from other GIS applications such as ESRI's ArcView (via support for shapefiles, BIL, FLT, GeoTIFF) and with remote sensing, image processing systems such as ENVI (Environment for Visualizing Images).

 

Many of the grids computed by RiverTools are required as inputs to distributed hydrologic models. A new hydrologic model called TopoFlow can be used as a plug-in to RiverTools to create a powerful, hydrologic modeling and visualization environment. Both RiverTools and TopoFlow are written in Interactive Data Language (IDL), a product of Exelis Visual Information Solutions (formerly ITT).

 

By itself, RiverTools is a full-featured application that uses an intuitive Graphical User Interface for access to all of its powerful mosaicking, visualization and analysis routines. However, RiverTools can also be used together with IDL, so that IDL can serve as a fast and robust scripting language for extending RiverTools. IDL is an easy to use, cross-platform language for visualization, analysis and rapid application development that can be purchased separately from Exelis Visual Information Solutions. IDL makes it easy to add your own custom processing routines to RiverTools and to link RiverTools with other applications and code written in C, C++ or Fortran. The RiverTools Command Reference documents a large number of RiverTools commands that can be used at the IDL command line or in your own IDL programs.
