036] Global Mapper - Attribute Editor: Layer Attribute Editor 01

Image
Until now, we have only covered methods for selecting and editing the attributes of registered objects directly using the mouse. Today, we will learn how to check and edit elements included in a layer as a list. This is much more efficient when dealing with large datasets. First, please download the sample file below. It is a shapefile (.shp) containing building data. Attachment: Building.zip (This is a safe proprietary data file for Global Mapper.) When you load the BD.shp file, you will see the building data as shown below: [img 1 : Global Mapper screen showing loaded building shapefile data] Until now, if you wanted to view the attributes of an object, you likely used the Digitizer Tool (pencil icon) or the Feature Info Tool . [img 2 : Feature Information window showing specific building ...

054] Global Mapper - Exporting by Specifying an Area

Image
While looking back at my previous posts, I realized I had missed one of the most frequently used functions in Global Mapper: selecting a specific area and exporting it in the desired format. Global Mapper is perhaps one of the most versatile GIS tools when it comes to the sheer number of formats it can import and export. Because of this, many users utilize it as a conversion and editing stage before moving data to their final production tools. Let’s get started. First, please download the file below. It is a digital map containing building information. Cur_BD_2.zip   (This is a safe proprietary data file for Global Mapper.) [img 1 : Bandizip window showing contents including shp, dbf, and prj files] If you drag and drop the downloaded file directly into the Global Mapper screen without...

053] Global Mapper - Comparing Terrain Changes: Path Profile

Image
Today, we will learn how to check how the terrain has changed using two DEM (Digital Elevation Model) datasets and the "Path Profile" tool. It's simple. You just need to turn on all the DEM layers you want to compare and then run the Path Profile tool. First, prepare two DEM files. [img 2 : DEM data from 2024-12-01] [img 3 : DEM data from 2025-01-01] Import both files into Global Mapper. [img 4 : Global Mapper Control Center showing two loaded DEM layers] As you can see, two layers have been registered in the Control Center. Drawing a Section Line Now, draw a section line across...

[048] Global Mapper - DEM Partial Elevation Correction: Terrain Paint Options

Image
In our last session, we covered how to correct an entire DEM layer. Today, we will learn how to modify only a specific area of your DEM data. With your DEM data open: [img 1 : Enable Terrain Painting icon in Global Mapper toolbar] Click the Enable Terrain Painting menu. The Terrain Paint Options window will appear. [img 2 : Terrain Paint Options window interface] Terrain Paint Options Breakdown Layer: Select the DEM layer you want to partially correct. Selected Layer Cell Size: This shows the grid size of the currently selected DEM layer. Note that trying to modify an area smaller than this size is generally meaningless. Operation: This defines the correction method. There are a total of 9 mod...
