## Wndsn Quadrant Telemeter Tutorials

*Making the most out of our graphical telemetry computers.*

Like with many complex instruments, there are multiple ways to solve certain problems and to measure the required inputs. Combining the various functions leads to a multitude of advanced uses.

## Wndsn Range Calculator Web Apps

We currently offers two calculators as companion tools to Wndsn Quadrant Telemeters.

- A range calculator; taking input from angular size in degrees, mil, or moa, and returning the respective distance to a given object of known dimension(s); depth of a well, height of building, etc.
- An elevation calculator, taking as input two angles; the lower and upper bounds of an object of known size in order to measure the altitude difference relative to a shared base, e.g. the distance to a lighthouse of known height, measured from a skyscraper of unknown height, or the altitude of a structure on a mountain, measured from a valley, or the distance and altitude of an airplane of known size.

Both calculators are 'RESTful,' which means that one can bookmark calculations and their results as well as determine specific parameters to receive the results in JSON, XML, or as CSV in order to subsequently use the data in processing applications.
