020] How to Use Point Layer Attributes in Global Mapper | Calculate & Formula Methods

Image
Automate Point Layer data management by performing arithmetic operations and complex formula-based attribute calculations. This tutorial explores the "Calculate/Copy Attribute Value(s)..." feature in Global Mapper. You will learn to add new attributes, duplicate existing data, and leverage the formula engine to streamline data preparation for 3D GIS and urban simulations. How to Use Calculate/Copy Attribute Value(s) The following four items are what differentiate point layers from elevation or raster layers, and they are commonly used in all vector-attribute layers: img 1 : Point Layer's Context Menus Calculate/Copy Attribute Value(s)... JOIN - Join Attribute Table/File to Layer Create Label Layer... SPLIT - Split Into Separate Layers Based on Attribute Value... Open the file from our last session and activate the point layer. img 2 : Control Center window showing the Poi...

019] How to Create Area Features from Raster Image Colors in Global Mapper

Image
Learn how to vectorize satellite imagery and extract specific color-based area features. This tutorial explores the specific context menu options available for Raster Layers in Global Mapper. We focus on the "Create Area Features from Equal Values" and "Vectorize Raster" tools, demonstrating how to isolate specific land cover types or features by targeting RGB values and adjusting color fuzziness settings. Today, we will cover the context menu for Raster Layers . Open your previous project and activate the 'Image' layer. img 1 : Control Center window with the "Image" layer selected and satellite view showing agricultural land. Let's review the context menu functions available for Raster Layers. You'll notice they are similar to those of elevation layers, but a few items are missing: img 2 : Raster Layer's Context Menus.

016] How to Automate Parcel Image Exports in Global Mapper Using Python

Image
Batch export high-resolution parcel images with satellite backgrounds using Global Mapper's Python SDK. This tutorial provides a complete Python script designed to automate the repetitive task of zooming into individual parcels and capturing images. By leveraging Global Mapper's scripting capabilities, users can process hundreds of vector features into standardized image outputs in seconds, significantly improving report generation efficiency. Why I Created This Script Today, I’m finally sharing a script I wrote some time ago and recently refined. I ask for your understanding; it has been difficult to concentrate on writing lately. The reason I created this script was because I saw a close junior of mine manually zooming in and out of hundreds of parcels in CAD, capturing each one for a report. I figured there had to be a better way than manually capturing hundreds of parcels one by one. img 1 : Main...
