About Zip line
This application was created in order to help search and rescue teams to better set up a zip line.
with this application the user can take a picture, mark the start and end point of the zip line and the application will calculate how the rope will look like when holding weight on it.
the user can set the weight, rope length, strengthening force and other variables.
the user can, in the sketch mode, do a calculation and draw himself the obstacles on the chart.
this will prevent the rescuee from colliding into obstacles along the zip line.
