HOW TO CALCULATE INCLUDED ANGLE FROM BEARING

 


Principle of Compass Surveying

 In compass traversing the directions of survey lines are fixed by angular measurements and not by forming a network of triangles.

 A compass survey is one in which the traverse work consists of series of lines the lengths and directions of which are measured with a chain or a tape, and with an angular instrument respectively.

 A traverse may be classified as:

a) Closed traverse

b) Open traverse

A) Closed traverse:

                   A closed traverse is a traverse in which the sides of a traverse form a closed polygon.

 B) Open traverse:

                   An open traverse is a traverse in which the sides of traverse do not form a closed polygon.

Included angle method:

                    In this method we measure magnetic bearing of any one line generally it is first traverse line and we measure included angles at all stations. 

The link given below will describe about the calculation of included angle from bearing :

Traffic Engineering Design Process

Pre-Design Considerations Site Analysis Before creating a design, traffic engineers need to conduct a site analysis to determine what needs the site may have for the area’s traffic. They will need to take note of the surrounding area – businesses, schools, railways, protected lands, etc. – and investigate any local policies that might affect their work.  Traffic Surveys A traffic survey is a survey conducted by traffic engineers to determine how traffic moves through a particular area. These usually take 2-4 days per intersection to complete and need to occur throughout the day to ensure both peak and non-peak hours are factored in. One of the most popular ways a traffic survey is conducted is with the use of rubber hoses. These hoses run across the road and connect to a meter that counts each vehicle that passes while also determining what type of vehicle it is. These hoses also collect data on what speed the vehicle is going when it passes over the hose.  Traffic engineers will als

  9 Elements for Designing Your Ideal Bathroom: A Practical Guide for Function and Style Designing a Functional Bathroom When it comes to your home, few spaces are as personal as the bathroom. It’s not just a functional necessity; it’s a sanctuary where you start and end your day. Creating a bathroom that seamlessly blends function with style is key to turning it into your ideal oasis. Let’s explore the essential elements that make up a well-designed and practical bathroom. 1. Storage Solutions: Declutter and Delight No one likes a cluttered bathroom. Invest in built-in cabinets, shelves, and storage niches to keep your essentials organized and within reach. Vertical storage is your secret weapon, especially in smaller spaces. A tidy bathroom is a peaceful one. 2. Layout Matters: The Bathroom Work Triangle Ever heard of the bathroom work triangle? It’s all about optimizing the layout for easy movement. Position the sink, toilet, and shower or bathtub strategically to crea
