049] How to Import WKT and XY Coordinate CSV Files in Global Mapper (Points, Lines, and Polygons)

Image
Overview of CSV-Based Geometry Import in Global Mapper Learn how to import points, lines, and polygons from CSV files using WKT and Coordinate List formats. While Shapefiles are standard, CSV files offer a lightweight and human-readable alternative for storing GIS data. This tutorial demonstrates how to correctly configure Global Mapper to interpret text-based geometry definitions (WKT) and consecutive coordinate lists, ensuring your data is accurately positioned on the map. Recommended Audience: GIS Analysts, Data Preprocessors, and Global Mapper users managing non-standard data formats. Previously, we covered how to import points using CSV files. Today, we will explore how to import more complex geometries—points, lines, and polygons (areas)—stored within a CSV file. You might wonder why anyone would store line or polygon data in a CSV file when the SHP format is so well-supported. There are several good...

041] How to Customize Feature Labels in Global Mapper

Image
Configure dynamic feature labels to display attribute data directly on your GIS map layout. This tutorial covers the essential settings for labels in Global Mapper. You will learn how to set default labels, use multiple attributes simultaneously, create custom format strings with variables, and adjust font styles and positioning for professional cartographic results. We will look into Labels . There are various options available, but since I haven't often felt they are particularly "pretty," I will cover them in a broad, general sense. First, let's draw an Area . img 1 : Global Mapper Modify Feature Info window and created area When you register an object, the Modify Feature Info window appears by default. Here, you must specify the Name , Feature Layer , and other details. The Feature Attributes section automatically adds properties based on the type of object registere...

040] How to Customize Point Styles, 3D Symbols, and Quiver Plots in Global Mapper

Image
Point Styles and Quiver Plot Visualization Configure custom point symbols, apply 3D models, and visualize direction and magnitude data using Quiver Plots. In this session, we explore the Point Styles in Global Mapper. Beyond simple markers, you will learn how to assign 3D models for terrain visualization and how to use attributes to generate direction vectors (Quiver Plots) for wind or water flow analysis. We're going to cover Point Styles . I believe you’ve already become familiar with the basic flow of applying styles through our previous sessions on Area and Line features, so let’s go through this quickly. Let's Start. Creating Point Features and Applying Custom Styles img 1 : Global Mapper Digitizer Tool - Right Click Menu - Create Point/Text Feature Select the Digitizer Tool , right-click on the screen, and select Create Point/Text Features -> POINT/TEXT - Create New Point/Text Feature ...

039] How to Customize and Apply Line Styles

Image
Global Mapper Line Styling Overview (Vector Visualization with Line Styles) Learn how to apply built-in feature types and design custom multi-layered line styles for professional GIS mapping. This tutorial provides a comprehensive guide to managing line features in Global Mapper. We cover everything from initial digitization and applying pre-defined styles to creating unique custom types and editing saved styles through the configuration menu. In this session, we will explore how to apply Styles to Line features. The process is similar to the Area styling workflow introduced in the previous lesson, so we will focus on key differences First, open Global Mapper and draw a line segment using the Digitizer Tool . img 1 : Global Mapper Digitizer Tool menu for creating new line features Once you...

038] How to Style Area Features in Global Mapper (Fill Patterns, Borders, Transparency Guide)

Image
Learn to define and automate the visual representation of polygon data through comprehensive hatch patterns and border configurations. This tutorial provides a comprehensive guide to styling Area features in Global Mapper. We cover everything from using standard pre-defined feature types and creating custom hatch patterns to adjusting transparency and streamlining workflows using auto-apply settings. In this guide, we will explore how to style the appearance of each element. Topics not directly related to styling will be covered in future tutorials. Creating and Styling Area Features Step 1: Creating an Area Feature First, please create an Area on the main screen. Once you finish drawing it, the Modify Feature Info window will appear as shown below. img 2 : Creating a new Area feature and the resulting info window Name: Set the name of the object. Feature Style: You can apply a pre-defined style or ...

044] How to Create Perpendicular Lines Along a Path in Global Mapper

Image
Automatically generate perpendicular cross-section lines along any selected path or boundary for precise site analysis. This tutorial covers the "Create Perpendicular Lines Spaced Along Selected Line/Area Feature(s)" tool in Global Mapper. You will learn how to set intervals and define perpendicular lengths, which is essential for professional road, river, and site cross-sectional studies. Today, we will explore the "Create Perpendicular Lines Spaced Along Selected Line/Area Feature(s)" tool, which draws perpendicular lines at regular intervals along a selected feature This feature is frequently used in drawings for cross-sectional analysis of business sites, roads, and rivers. Preparing the Line and Area Features First, draw an Area and a Line arbitrarily on the main screen. img 1 : Drawing Area and Line in Global Mapper After selecting both objects, Creating Perpendicular Lines Along S...
