Fully integrated sightings from all optics – BigEyes, Handhelds, Theodolites, and inclinometers


The latest version of Mysticetus ( now fully integrates all sightings from all optics on a single entry sheet….if you want it to.

If you don’t, then that’s cool. Say you’re just doing aerial surveys and will never be using binoculars or theodolites, don’t worry. You don’t have to change how you currently do things. It’s Mysticetus, so that means it is completely configurable by you in the field.

But if you do, want your theodolite sightings, binocular sightings and even inclinometer-based sightings (say, from an orbiting plane communicating via AIS) to all show up in a single data entry sheet and, coupled with the Resight formula which calculates sighting speed and heading, create a unified display and record of your sightings.

To achieve this, the latest version of Mysticetus includes a new formula: DistMultiOptics. This – along with some creative re-orienting of existing Theodolite formulas – serves as the cornerstone to enabling selection of any optics device. There is also a new “Sample Templates.Mysticetus” file on the download page that shows how all these formulas interact. I highly recommend you start from this template as the formulas get more and more intertwined as you add more optics options. (or just give me a call and I’ll step you through your specific setup).

The DistMultiOptics formula specifies three things: a column for angle or reticle, a column for selecting optic type, and a column for selecting the observers altitude (which also be derived from a GeoPosition field such as that obtained from a GPS or altitude override).

The output is radial distance to a sighting – of course, taking into account the curvature of the earth, angle between horizontal and horizon if you are using a reticle-based device, and so on.

The sheets end up looking like this:

Let me know if you have any questions or suggestions (or need help setting this up for your survey).

IMPORTANT NOTE: some of you are already using the version which separates BigEye, Handheld and Theodolite sightings into different sheets. This system no longer works and you will need to migrate to the new, integrated system when you upgrade to build 98.

Anyways, I hope your summer is off to a great start. Here in the Seattle area we’ve switched from griping about rain to griping about the heat. Yes, we Pacific Northwesterners are weird.
