Terrain Analysis

The Civil Terrain Model Analysis tool set contains tools to compute volumes, display coordinates, elevations and other data about points or between points on the model, and analysis of ponds, watersheds.

Setting

Description

Points

Analyze Between Points - Reports information between 2 point locations on a terrain model (elevation difference, length and slope).

Analyze Point - Reports information about a user-specified point location in a terrain model (elevation, slope, contour, slope direction).

Inverse Points - Reports information about a user-specified point location in a terrain model (elevation, slope, contour, slope direction). Several types are supported: linear, arc, radial, perpendicular and by element. The tool is supported in both 2D and 3D views / models. The results are displayed at the cursor prompt, and optionally, the Civil Report Browser

Volumes

Create Cut Fill Volumes - Calculates cut and fill volumes between two surfaces, usually an existing a terrain and a surface (terrain or mesh) and creates a 3D mesh solid with volume attributes.

Analyze Volume - Calculates volume between 2 terrain models or a terrain model and plane (elevation). Capable of processing in an area (fence) or multiple areas and computing the volumes over a range of elevations. Cut and fill factors are also options.

Hydraulic

Analyze Pond - Analyzes terrain model for ponds (low point) located via a data point location on a terrain model (volume, area max depth).

Analyze Trace Slope - Traces along a surface either following a user-specified slope value or the steepest slope. Can trace upstream or downstream.

Reporting

Report Crossing Features - Locates intersecting line features, such as break lines or contours.

Report Conflicting Points - Reports source data used to create the terrain model with duplicate points (as defined by an X, Y location with the same or differing elevations).

Aquaplaning

Tool to evaluate potential for vehicle to lose control on wet road.
