Today is our third session on Spatial Operations , focusing on Transforms . What makes this feature different from the previous two is that it doesn't just select, split, or delete; instead, it targets a single layer and creates new geometries based on the elements contained within that layer. Let's get started. First, open the file from the previous session. Since this content doesn't require extensive explanation, we'll go through it quickly. [img 1 : Global Mapper Control Center showing the layer list including Area01] Activate the Area01 layer. Now, let's examine the menu. [img 2 : Spatial Operations dialog box focusing on the Transforms tab] Spatial Transforms: Methods for Generating New Geometries MBR (Minimum Bounding Rectangle): Generates the minimum bounding rectangle for the selected geometry group. It creates the smallest possible rectangle that encompasses all features. Centroid: Calculates the center point of Area or Line featur...

Today, in our second session on Spatial Operations , we will explore Predicates , which offer a more granular approach than the basic operations we discussed previously. Admittedly, there are some limitations. Since these operations typically involve only two layers at a time, you might find yourself thinking deeply when dealing with multiple layers. However, most spatial operations can be successfully performed using these methods. 1. Getting Started First, let’s open the file we used in the last session. Global Mapper Control Center showing various vector layers including Area, Line, and Point In the Control Center, you can see our sample layers: Area01 , Area02 , Line01 , and Point01 . Now, let's launch the Spatial Operations tool and navigate to the Predicates tab. 2. Understanding Spatial Predicates UI Spatial Operations dialog with the Predicates tab selected The Predicates tab has a similar layout to the Operations tab we handled last time. However, it fo...

Today, we will dive into Spatial Operations . These functions allow you to perform various geometric tasks such as merging shapes, subtracting one from another, finding intersection areas, or identifying elements contained within specific regions. We will practice using the following file: Attachment: Operation.zip  (This is a safe proprietary data file for Global Mapper.) Once you have downloaded the file, please open it in Global Mapper. Setting Up the Workspace Upon opening the file, you will see four layers in the Control Center: two Area layers, one Line layer, and one Point layer. The Spatial Operations tool can be found in the top menu bar under Vector Analysis -> Spatial Operations... Select "Spatial Operations..." to open the configuration window. As shown in the dialog, there are four primary types of spatial operations: Operations: Performs geometric calculations between layers. Predicates: Used for searching or filtering features. Tra...
