Contour.Core

A .NET library for generating contour lines and polygons from scattered geospatial data using triangulation-based interpolation. Designed for creating noise contour maps around airports.

Features

  • Generate contour lines and polygons from triangulated point data with scalar values
  • Lambert Conformal Conic map projection (compatible with AEDT/Esri)
  • Triangle edge intersection detection and linear interpolation
  • Built on NetTopologySuite for geometry operations

Getting Started

Prerequisites

  • .NET 8.0 or later

Installation

Add a reference to the Contour.Core project or package.

Usage

The library exposes the IContourGenerator interface with two main operations:

// Set up triangulated input data
generator.SetTriangles(triangles);

// Generate contour lines for specified intervals
var lines = generator.GenerateContourLines(intervals);

// Generate contour polygons
var polygons = generator.GenerateContourPolygons(intervals);

Project Structure

  • Contour.Core - Core library
  • Contour.Core.Test - Unit tests (MSTest)
