045] How to Create Shortest Path Lines from Points to Lines (Chainage Tool)

Image
Learn how to generate the shortest connecting segments between points and lines while automatically calculating chainage distances. This tutorial explores the "Chainage - Connect Selected Points to Selected Lines" feature in Global Mapper. We cover the initial setup, attribute configurations such as offsets and start points, and the process of displaying results using custom labels for technical documentation. Creating Shortest Path Lines Between Points and Lines This function can be used to measure how far a specific point is from a river or road in a straight line, to determine the distance of an intersection from the start or end of a road, or to identify the best location when branching water and sewage pipelines. Let's get started. First, draw some points and lines on your screen. img 1 : Initial points and lines drawn in Global Mapper Running the Cha...

046] How to Create Parallel Offset Lines in Global Mapper

Image
Learn how to generate multiple parallel offset lines from selected vector features at precise intervals. This tutorial demonstrates the dedicated parallel line creation tool in Global Mapper. We move beyond the old workaround of converting buffers to lines and explore the settings for spacing, directional orientation, and non-overlapping geometry to streamline your GIS drafting workflow. In this tutorial, we will learn how to create precise parallel offset lines in Global Mapper using the built-in Advanced Feature Creation tool. Previously, this specific feature was not available in Global Mapper. In the past, we had to draw buffer lines and then convert those buffers back into line features to achieve a similar result. Let’s get started. Creating Parallel Offset Lines in Global Mapper First, draw a line on the screen and select it. img 2 : Right-click menu showing Advanced Feature Creation Options R...

023] How to Close Gaps Between Adjacent Features in Global Mapper Vector Layers

Image
Align vertices and eliminate topological gaps in vector data with one click. This tutorial explores the "Close Gaps Between Adjacent Features" function in Global Mapper, a specialized tool for fixing tiny, unintended gaps between lines and polygons—essential for cadastral mapping and engineering blueprints. Today, we will explore the final item in the layer context menu that applies to all vector layers: "Close Gaps Between Adjacent Features..." In digital mapping projects, especially when dealing with cadastral maps or engineering blueprints, you might encounter tiny, unintended gaps between lines or polygons. The "Close Gaps Between Adjacent Features" function is designed to eliminate these gaps by aligning the positions of vertices (vertex snapping). While this isn't a tool you'll use every single day, it is incredibly efficient for shortening the time spent manually zoom...
