About Points
Points are one of the data types that you can work with in the Map window's layer manager.
The points database enables you to add reliable control data to the gridding component of WinPICS , in order to address the extrapolation inaccuracies that occur when gridding in areas of the map that have little control. These inaccuracies, arising naturally from mathematical interpolation, are aggravated by the lower quality of seismic data collected in the edges of the area.
What is a point?
In WinPICS , a point is a position in space with a series of numbers for a label. In 2D space, it has two numbers (x, y) in the sequence. In 3D space, it has three numbers (x, y, z), where z is a measure of a dimension of interest (for example, time, or depth). The number values can be positive or negative. WinPICS has no way of knowing what the values mean, so it is up to the user to name the point data.
Import or create points
You can import existing points into your project by using the menu option in the Application toolbar.
The points data itself displays in WinPICS as a named point set. You can organize point sets into groups, which are folders in the layer manager. Use the layer manager to create a new group of points. Read more
- WinPICS automatically converts points imported as a shape file into filled circles on your map. However, you may have to zoom in to a lower scale to see the points. To make sure you are looking at the right area of the map, right-click on the newly imported points in the layer manager, and select .
Use the Points tab shortcut menu to edit, merge, rename, and perform other actions on the points.
Gridding with points
You can select points as an attribute when you set up your gridding. The points you use should be compatible with the type of data you're gridding. So if you want to grid on horizon time, then the points data should be in milliseconds.
