This app helps Marine Mammal Observers calculate distances between animals and acoustic sources during surveys. It uses trigonometric functions and allows users to input target and source bearings and distances for precise mitigation decisions.
4.0.1
September 25, 2018
This latest update to the MMO Range Finder includes the following (and much much more!) Now equipped with maps. Your sightings can be displayed on a map with your ship and mitigation zone. Choose between conventional, 'x-bow' and 'ramform' ship symbols for the map, all correctly scaled to the real ship dimensions. Press the radar button to show the map orientated to the vessel heading. Radar button also displays the distance from the target to the center of source as well as the bearing from the ship to the target for ease of re-sighting. Compass direction indicator guides you back to your sighting. Swipe left on any text-field to delete. Your data can be saved to the log and exported as a .csv using a variety of methods (email, Dropbox, iCloud, etc). A user manual for the MMO Range Finder can be accessed from the app. All app settings are now found within the app. User does not need to leave app to make changes. Added option to calculate the great circle distance between the target and source when GPS is enabled. Bug fixed related to pressing reticule converter button more than once.
MoreMMO Range Finder is a utility app designed to assist Marine Mammal Observers in calculating the distance between animals and acoustic sources. This is crucial for making informed mitigation decisions during various types of surveys and projects.
The app utilizes a trigonometric cosine function. Users input the distance and bearing to the target and source from their observation position, and the app computes the necessary distances for mitigation.
Yes, it can convert binocular reticule readings to distance by using a specific formula, as referenced in Lerczack and Hobbs (1998). It also allows for setting up observation locations with height above sea level for accuracy.
Yes, the app allows users to save data for each sighting and export it in .csv format. This is useful for subsequent mapping and analysis of the collected data.
The map displays vessel position, the mitigation zone, and projected fauna sightings. It also shows latitude, longitude, course, and speed, and can orient to the vessel's point of view for live updates on sightings.
No, MMO Range Finder is a paid application. It is available for purchase on supported devices for a one-time fee of $0.99.
The latest version of MMO Range Finder is 4.0.1, which was last updated on September 25, 2018. Users can expect updates to improve functionality and address any issues.
MMO Range Finder is compatible with iPhone, iPad, and iPod devices. It is suitable for users who require its specialized utility functions on Apple mobile devices.
