From Crookneck Consulting:
Visual field-of-view calculator and shot planner for outdoor photographers. The Photographer's Transit ("Photo Transit") is a map-based shot planning tool for outdoor photographers who use interchangeable lens cameras (such as SLRs). Plan the best possible camera, lenses and shooting locations for your photo trip or assignment using the sophisticated built-in field of view simulator. Photo Transit includes detailed elevation profile information so you can scout your sightlines ahead of time, and check whether your planned focal length will capture your subject. Photo Transit's vertical field of view chart lets you see if your subject will be visible or obstructed by the local terrain. Create projects containing detailed shot lists, including camera and subject location, height above the ground, pitch, orientation and focal length. Share your planned shots with colleagues and friends via email and social media, or export them as KML for use in your favourite GPS app. With a rich feature set including Google Street View, and offline maps and elevation data, and a choice of elevation data sources, The Photographer's Transit is a powerful tool for any photographer who likes to be well prepared.

Note: This app is designed for photographers using interchangeable lens cameras (e.g. SLR, Micro 4/3rds, Medium/Large format film). Maps and elevation-based calculations require a data connection unless an offline data source is used. Maps and elevation data must be viewed while connected to the internet in order to be saved for later use offline. Not all map types and elevation data sources are available offline. Topographic map data is available only between 60'N and 47'S. Overlay maps are not always available for the highest zoom levels. Topographic maps courtesy of OpenCycleMap.org. OSM map tiles courtesy of CartoDB. Google Elevation data is subject to daily usage limits per IP address. Availability of specific map types and Google Street View is dependent on 3rd party map service availability, terms and conditions, and is subject to change.

Plan the perfect vantage point for your photographic subjects and enjoy a better field of view.
