WQStat Plus Overview

QuickSURF is the most advanced digital terrain modeling and earthworks analysis program available. This software can be used in a broad range of professional disciplines, such as civil, environmental, petroleum, and mining engineering; geological mapping and exploration; surveying; photogrammetry and topographic mapping; landscape architecture; oceanography; and surface visualization.

» Overview

AutoCAD and Standalone Versions

QuickSURF is available either as an AutoCAD® application, or with its very own standalone Microsoft® Windows™ CAD system. As an AutoCAD application, QuickSURF easily integrates with other third-party AutoCAD applications allowing sharing of data. As a stand-alone Microsoft Windows application, QuickSURF is integrated with its own 3D CAD system that is 100% compatible with AutoCAD and MicroStation® allowing it to directly read and write DWG and DGN drawing files.

Exceptional Surface Modeling

QuickSURF provides several surface modeling algorithms to produce accurate three-dimensional surface models. Some of these modeling algorithms include triangulation, gridding, triangulation gridding, krige gridding, and trend gridding. Surface models can take the form of a triangulated irregular network (TIN), gridded mesh, triangulated gridded mesh, or contour lines. Surface modeling results are quickly computed and instantaneously displayed onto the screen prior to adding the computed surface to the drawing.

The software can manipulate and display an unlimited number of surfaces simultaneously, making it a powerful surface analysis and design tool. For example, computed topo maps can be compared to the actual physical site, making subsequent adjustments and corrections to the surface model quick and easy.

Written entirely in the C programming language, QuickSURF is fast and accurate processing over 100,000 points per minute, with a numerical accuracy of 16 decimal places. Unlike other surface modelers, QuickSURF gets the surface triangulation right on the first pass. No manual TIN editing is required as with other packages; no manual swapping of triangle edges; no patched re-triangulation. When refining a surface with QuickSURF, simply add the additional breaklines and the program will instantly create a revised surface honoring the new breaklines.

With QuickSURF’s unparalleled speed, where other surface modelers can take up to 4 to 5 hours to create or revise a surface, QuickSURF does it in just minutes. And, there is no limitation on the number of points or surfaces which can be processed. QuickSURF utilizes virtual memory, so the size of a surface model is limited only by the available hard disk space. Some users have built maps containing well over 10 million control points.

Spatial data for surface modeling is accepted from many sources, including columnar ASCII text files, coordinate geometry (COGO) programs, data collectors, spreadsheets, and databases. Spatial data can also be derived from AutoCAD and MicroStation drawing files by extraction of points, polylines, blocks, and other entities. Spatial data can be defined using an unlimited number of 3D control points. Surface breaklines can be defined by drawing 2D or 3D polylines or by importing an external ASCII text file describing the breakline coordinate points. The software will then honor the specified breaklines when creating the surface model. Surfaces can be colored based upon degree of surface slope, surface slope direction, elevation, visibility, light direction, or by mapping Z values from another surface model.

Cut and Fill Earthworks

Both cut and fill earthwork volume calculations can be performed for single or multiple areas. Slopes, structures, and cut and fill surfaces are easily developed. Mathematical spatial operations can be performed between any two surfaces. Cut and fill regions can be specified using user-defined polygons. These polygons might represent bridge embankments, earthen dam structures, floodway encroachments, stormwater detention ponds, building foundation pads, property boundaries, and sheet piling. The program also contains basic modeling tools for designing roadways, including vertical curve design, roadway cross-sections, and slope intersection.

Advanced Contouring Capabilities

QuickSURF allows contours to be generated at any time. Complete user control of contour increment intervals is provided. If desired, contour elevation intervals can be specified in an external ASCII text file, at any varied elevation spacing desired. Contours can be trimmed using user-defined internal and external multiple clipping boundaries. Contour lines can be drawn as closed polygons to allow hatching and color fills. Contours can be quickly smoothed using B-splines. In addition, contours can be annotated with elevation labels, colored relative to elevation, highlighted to indicate specific contour intervals, and hachured using contour tickmarks to indicate slope direction.

Quickly Create Cross-Section and Profile Views

Cross-section and profile section views can be quickly created from any surface model. QuickSURF will take a 2D polyline drawn in plan view and then convert this polyline into a 3D polyline which conforms to the computed surface model, thereby creating a section view of the surface along that polyline. In addition, the resulting section view can be flattened, thereby displaying the total accumulated distance along the polyline. The user can instruct the software, using a single command, to scale and rotate the section view into plan view, draw an X and Y axis, display a background grid, and label the X and Y axis. Full control over all aspects of section view creation is provided

Multiple Platforms Supported

QuickSURF is an AutoCAD application, and is also available as a standalone Microsoft Windows application , which includes its own 3D CAD user interface.
