Greetings MarMam, Got megafauna to measure from drone imagery? We are excited to announce that MorphoMetriX version 2 is now available! https://github.com/ZappyMan/MorphoMetriX-V2/releases MorphoMetriX is an open-source photogrammetry software developed as a user-friendly graphical user interface (GUI) with the flexibility to make customized length, width, area, and angle measurements with no required knowledge of any scripting language https://doi.org/10.21105/joss.01825. Some exciting new features for v2 include: · Easier downloading – no more command line. Instead, download .dmg (MacOS) and .exe (Windows) files directly and launch from your applications folder. The MacOS version is functional for both M1/M2 and Intel chip processors. · Efficient width measurements – the ‘Measure Widths’ function automatically divides a length measurement into perpendicular widths based on the designated number of width segments specified by the user. MorphoMetriX v2 now automatically places slidable width points on each perpendicular width line, enabling the user to easily adjust and edit width measurements until satisfied with each placement, whereas in v1 users had to manually click each width point with minimal editing ability. · Adjust color & size of width points – users can now customize the color and size of the width points to create contrast with the image and ensure that points do not obscure the view of the animal. · Mirror side – a new feature to help with measuring widths when one side of the whale is obstructed, i.e., glare, waves, shadows, refraction. Users can now select the whale’s “better side” and the distance between the width points on that side and the body length line are multiplied by two. This saves data from being thrown out! · Improved exporting – measurements are now exported in both meters and in pixels and saved in long format csv, for a more interpretable output that can easily be linked with additional metadata. · Automatic crash report – if MorphoMetriX v2 crashes, a crash report is automatically generated and saved so that it can be uploaded as an “Issue” report on GitHub to help communicate issues and further improve the program. MorphoMetriX v2 can be downloaded here: https://github.com/ZappyMan/MorphoMetriX-V2/releases Manual: https://github.com/ZappyMan/MorphoMetriX-V2/blob/master/MorphoMetriX_v2_manu... Note that development of CollatriX v2 (https://doi.org/10.21105/joss.02328) is underway and a pre-release is currently available that is compatible with outputs from MorphoMetriX v2 (https://github.com/cbirdferrer/collatrix/releases/tag/v1.0.9 ). Keep an eye out for the final release of CollatriX v2 this fall, which will include several new features to help with processing and linking metadata with measurements. Our team is also working on developing some new tools for our photogrammetry workflow, if interested in receiving updates about new releases (like CollatriX v2) and events (such as workshops) please subscribe to our listserv here: https://lists.oregonstate.edu/mailman/listinfo/codex A huge thank you to all the users and beta testers who have provided awesome feedback over the years, which has helped us shape MorphoMetriX v2 into a more efficient, robust, and easier to use photogrammetry software. Thank you so much for all your help and support!
