What is a Control Line?
A Control Line is a reference datum used for defining the location of Lots. These are usually defined by survey references, but can also be coordinate systems (such as latitude/longitude) or landmarks.
What is the purpose of Control Lines?
Control Lines allows a lot to be identified by its location and its area of work referenced geographically for your project.
How to Set Up?
You can set up your Control Line register by adding them individually or importing them as CSV files, either via Cloud or Desktop (D).
On Desktop, the Control Line register records only the Control Line code and its corresponding description. However, on Cloud, there is an additional page where you can add the coordinates of the Control Line and plot them on the map.
Tips for Users :
- For the Control line to work properly, you will need more than one point. It cannot be just a single point. You can add points by clicking along the map, or entering coordinates.
- If you have many coordinates, you can compile these into a CSV file and import them on Cloud.
- Negative latitudes represent the southern hemisphere ( South of the Equator), and negative longitudes represent the western hemisphere ( West of the Prime Meridian). Negative values can be added using the dash sign in Excel before saving it as a CSV file.
