Visual OTTHYMO 6.3 (VO) introduces major enhancements focused on cloud integration, groundwater modelling, GIS capabilities, and overall modelling efficiency. This version modernizes how users access, manage, and analyze projects while expanding VO’s continuous simulation capabilities.
The key updates in Version 6.3 are summarized below:
1. Microsoft-Based Login System
A new Microsoft-based login system replaces the traditional license file approach. This provides a more secure and streamlined user experience, allowing users to access VO from any authorized computer without managing license files.
2. VO Hub
The new VO Hub provides a centralized platform for accessing and managing both local and cloud-based projects. It improves organization, accessibility, and overall user experience.
3. Cloud Projects, Sharing, and Ownership Control
VO 6.3 introduces enhanced cloud capabilities, including:
- Uploading local projects to the cloud
- Sharing projects through a simple link
- Ownership transfer to control editing access
- Preventing multiple versions of the same project
- These features significantly improve team collaboration and project control.
4. Cloud History Tracking
A new cloud history system records detailed project changes, including user actions, timestamps, and modifications. This improves transparency, accountability, and project tracking.
5. Wetland-Groundwater Interactions
A major new feature allows users to simulate groundwater levels and integrate them into continuous models through the Wetland command. This improves accuracy in post-development scenarios and better represents surface–subsurface interactions.
6. Enhanced Coordinate System (CRS) Support
VO now includes expanded Coordinate Reference System (CRS) capabilities, including support for Geographic Coordinate Systems. This improves compatibility with global GIS datasets.
7. Layer Projection Tool
The new Layer Projection Tool allows users to reproject GIS layers directly within VO, ensuring all layers match the project coordinate system and improving spatial accuracy.
8. Erosion Modelling Improvements
Enhancements include:
- Adding critical flow values to parameter tables
- Highlighting channels exceeding erosion thresholds
These updates help users quickly identify erosion-prone areas.
9. Wetland Modelling Enhancements
Wetland modelling now includes improved reporting and visualization tools, such as:
- Pre- vs. post-development comparisons
- Monthly and annual analysis
- Graph and table outputs for easier interpretation
10. Calibration Improvements
Calibration tools have been enhanced with:
- Expanded calibration parameters
- Time filtering options for better analysis of long-term simulations
11. DEM-Based Transect Extraction for OTTHYMO
The automated transect extraction tool has been extended to the OTTHYMO engine, allowing users to generate and assign cross-sections using DEM and GIS data, reducing manual effort.
12. Home Tab Improvements
Updates to the Home tab include improved organization and relocation of commonly used tools such as Print, Basemap, and Save Results with Project for better accessibility.
