Britain's railways give locations as an ELR and a mileage instead of coordinates. Here's what that system is, why converting it to and from OSGB36 is harder than it looks, and how I work with it on site.
Surveying is all about observations. When you go on site, you often need to record not just topographical data, but also notes about your work.
Good record keeping is a must have in land surveying, and this is best achieved by always taking essential field notes in your survey field book.
Converting to and from SnakeGrid coordinates might seem a like a difficult task when you've never done it, but it's actually quite a simple procedure. In this article I will explain how to do different conversions to and from SnakeGrid coordinates.
At their very core Land Surveyors do measurements. To be more specific, a surveyor gathers positional data to produce accurate representation of the shape of the land and anything on it.
Whilst the term surveyor is all encompassing, there are other terms that are used to describe surveyors.
Land Surveying is the process of gathering, collecting, and processing geographical data for creating a informational report about the surveyed area.
Land Surveyors gather positional data to produce accurate representation of the shape of the land and anything on it.
The Trimble Survey Controller (TSC for short) has a few options to aid in setting up your instrument, each with its own pros and cons. In this article, I'll aim to explain how each Station Setup mode works and in which scenario you would use it.
Have you ever used targets and total stations from different manufacturers (e.g. using a Leica Target with a Trimble instrument) and wondered why you're having systematic errors in your data? Chances are you need to correct your constants.
