IrriExpress provides a straightforward, yet powerful platform for designing irrigation projects utilizing pivots, sprinklers, and drip systems. Users can assess potential installation options beforehand, survey various terrains, create contour plans, and implement detailed irrigation designs effortlessly. The program boasts an intuitive and adaptable interface, facilitating full irrigation system design while allowing for easy analysis and validation of various configurations. With capabilities for digital terrain modeling and computer-aided drafting, it eliminates the need for tedious manual calculations, the reduction of survey field books, or the plotting of terrains by hand. IrriExpress efficiently transforms survey information into a digital terrain model format, leveraging up to 9,000 survey points to create a triangular surface model. Additionally, it facilitates the generation of contour plans by importing data from ASCII coordinates, DXF, DWG, and GPS files. Furthermore, the software proactively identifies potential issues based on specified upper and lower limits for different slopes and angles, ensuring users can address challenges before they arise. This comprehensive approach significantly enhances the planning and execution of irrigation projects, streamlining the entire process.
