001] CityEngine Tutorial : Create 3D Buildings from SHP File (Extrude + CGA Guide)

Image
In this tutorial, you will learn how to automatically generate building heights using SHP files. This is the most fundamental process of 3D modeling using GIS data. 📌 What You'll Learn How to import SHP files correctly into a CityEngine workspace Mapping GIS attributes (Floor Count) to 3D geometry parameters Writing basic CGA (Computer Generated Architecture) rules Automating mass modeling for large-scale urban environments Generating a 3D city from 2D geospatial data is the cornerstone of Digital Twin and Smart City infrastructure projects. In this session, You will master the extrude function in CityEngine to automate the 3D modeling process using GIS attribute data, specifically the floor count. In this tutorial, you will start with a very simple task to create 3D buildings. [Final - 3D buil...

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...

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...

032] How to Set Up Map Layout Editor in Global Mapper (Paper Size & Bounds Guide)

Image
Learn how to configure custom paper sizes and define precise layout bounds for high-quality GIS report illustrations. This tutorial introduces the Map Layout Editor, a powerful tool that goes beyond basic printing to provide professional cartographic elements. We cover launching the editor, setting up custom dimensions (15cm x 15cm), and using the 'Draw a Box' method with the Shift key to select square map areas. Although it has a sophisticated name, it should not be expected to produce results comparable to QGIS. It is simply a tool that offers slightly more advanced functionality than basic printing. To follow along, you can open the print.gmp file from the previous session. Before starting the layout configuration, it is important to understand how the Map Layout Editor handles workspace data and page-based output. img 1 : Global Mapper main screen with print.gmp loaded How to Launch the Map Layou...
