欢迎您接见环中1xBET!
GWN-DTM是一款数字地形模型和等高线画图软件,新版本是6.0.x
?
GWN-DTM的职能
GWN-DTM能够同时处置数据,即便是大型项目,该软件已经通过一批处置500,000个空间点进行了测试。将数据分成更幼的集中,这能够节俭您的功夫并使您可能将精力集中在手头的项目上。您能够使用处置模式进一步节俭功夫和精力,该模式允许您离线处置多个工作。使用批处置模式,处置能够更快的实现。
?
使用GWN-DTM实现较大。GWN-DTM选取盛开式架构设计,即能够凭据您的要求批改软件。您能够归并自己的实用法式并依照挨次执行GWN-DTM的号令。
?
GWN-DTM能够用高程包办另一种丈量,从而使该产品易于适应超出地形建模正常领域的使用。例如,GWN-DTM用于天生化学浓度图以查抄地下传染。
?
GWN-DTM的可视化工具使用户能够分析表表并评估切割和填充要求。了局能够显示并用于设计获奖的演示文稿。GWN-DTM还接受调查汇报中的职能代码,可用于鉴别和分析元素。
?
通过使用GWN-DTM的批处置模式,能够离线下载和处置大型文件,而不会占用尊贵的推算机资源。GWN-DTM对推算机内存的要求与品质相结合,使该产品可能处置较大的项目。
?
GWN-DTM为刻薄的用户提供了显著的优势。使GWN-DTM脱颖而出的多多职能:
?
大量使用点数
GWN-DTM的GIS Quadcell步骤使该软件能够在一次通过中处置大量数量的点。将数据分成较幼的部门,但是即便在大的项目中,也能够获得了局、事实证明,GWN-DTM可处置4,000,000个数据点。
?
职能守护
能够将调查汇报中的职能代码导入GWN-DTM并分配的职能(色彩或图层)。这使用户能够打开和关关职能,以进行鉴别和分析。
?
代替高程进行另一项丈量
GWN-DTM能够基于除海拔之表的怀抱(例如化学浓度)天生表表。这允许用户创建浓度图,以援试炖估例如填埋场,安葬的化学物质泄漏或有毒物质泄漏。
?
地形模型可视化
GWN-DTM可视化工具,可援手分析数据和筹备演示文稿。这些工具:
凭据高程领域导入等高线,其中可以为高程分配分歧的属性(色彩,图层)
通过高程带导入地形模型,其中使用三角形而不是等高线。若是高程线横穿三角形,GWN-DTM将自动调整三角形
通过多边形导入地形模型,该模型可用于对地形模型中的多个项目分组,例如原始地面,路路或地面
裙部地形模型,实现 了地形模型的三维可视化
?
叠加网格
GWN-DTM能够凭据用户界说的网格距离和网格旋转来天生覆盖网格。单个栅格点的高程是从地形模型中获得的,能够使用以下三个选项之一将其写入文件:使用ttm高程,使用ttm高程+值或使用ttm高程-值。此选项可用于从地形模型创建覆盖网格偏移。
?
GWN-DTM提供了多种叠加网格输出的步骤:网格点,器材线,南北线或用户界说的多边形
?
体积精度
为了在进行曲面之间的体积推算时高,GWN-DTM要求用户界说包抄指标区域的多边形。使用此步骤可推算中不会指定区域之表的点,不然会谬误。
?
DWN-DTM还提供了查抄工具,使用户可能验证推算。例如,使用Contour Isopach TTM区域,能够目视查抄更改(切割和填充)的区域,以正确性。
?
网格体积
DWN-DTM的网格推算步骤使软件可能创建网格节点,而后能够使用分歧的选项将其导入:网格点;原始,建议和设计立面图;切割/填充或没有切割/填充量。用户能够节造属性(色彩/图层)分配给网格节点的操作,从而能够的显示分歧区域。
?
数据存储
GWN-DTM将数据存储在项目文件中,这使查找和使用文件。DWN-DTM文件能够通过设置在人员之间共享,也能够传递给员工或客户。
?
批量处置
使用GWN-DTM的批处置选项,大型数据文件的下载和处置能够离线进行。

英文介绍:
GWN-DTM is a powerful digital terrain modeling package ideal for even the biggest civil engineering projects. GWN-COGO is available as an AutoDesk or MicroStation add-on providing a low-cost surface contouring application alternative which runs inside AutoCAD or MicroStation. With GWN-DTM users can easily create contours, overlay grids, calculate volumes between surfaces, and substitute elevations with other data sets for contouring. ?for the design of dams, lagoons, settling ponds, landfills, roads or other surface features. ?
GWN-DTM is an ideal application for large scale earthwork projects, such as design of dams, lagoons, settling ponds, land fills or roads.GWN-DTM’s unique GIS Quadcell approach allows for use and manipulation of unlimited number of points – current projects include over 4,000,000 points– in a single file effortlessly and expediently. The first class visualization tools of GWN-DTM allow users to quickly analyze surfaces and evaluate cut and fill requirements. GWN-DTM also accepts feature codes from survey reports, which can be used to quickly identify and analyze elements.
?
GWN-DTM's Unsurpassed Power
GWN-DTM processes all data at one time even for large projects - the software has been tested by processing over 500,000 spatial points in one batch. There is no need to break the data into smaller sets, which saves you time and enables you to concentrate your efforts on the project at hand. You can further save time and effort by using the batch processing mode which allows you to process multiple tasks off-line. With batch mode, the processing can be done, for example, overnight.
?
Maximum Flexibility with GWN-DTM?
GWN-DTM has been designed with open architecture, i.e., the software can be modified to suit your specific requirements. You can incorporate your own utilities and execute GWN-DTM's commands in the sequence you need.
?
No Hidden Costs in GWN-DTM?
When you purchase GWN-DTM, you will not have any additional costs. There is no need to buy different modules to perform specific tasks. With GWN-DTM you get it all in one comprehensive package - from contouring to alignments, cross sections, earth works and slope analysis, it is all there.
?
Multi-platform?
GWN-DTM is available on MicroStation and AutoCAD on multiple platforms. Whether your choice is PC, Sun or HP workstations, DEC Alpha, Windows or a combination of these, you will find the same unequaled qualities of GWN-DTM working for you.
?
INTEGRATED PROGRAMS
GWN-DTM, GWN-COGO, GWN-STORM, and GWN-SURF are an integrated set of programs which provide powerful mapping, design, municipal applications, spatially-related planning functions, storm sewer design, and highway design to demanding users of engineering, scientific survey and mapping disciplines. They are interactive within AutoCAD and MicroStation.
