How to use ArcGIS to make a 3D topographic map

As a professional GIS software, ArcGIS can not only make two-dimensional maps, but also make three-dimensional maps. Usually, we use ArcScene to make three-dimensional maps. Here we will introduce the method of making three-dimensional maps, hoping to help you.

Preprocess data

Load the prepared rectangular surface, rectangular line and elevation DEM data into ArcScene, the effect is shown in the figure below.

loaded data

Right-click on the DEM data and select Properties, as shown in the figure below.

select attributes

In the displayed layer properties dialog box, select the Symbology tab, and select an appropriate color ramp according to your needs, as shown in the figure below.

Choose Ribbon

Click OK to complete the modification of the elevation DEM rendering method, as shown below.

In the same way, modify the style of the rectangular surface and the line, as shown in the figure below.

Stretch data

Open the DEM Layer Properties dialog box, select the Base Height tab, and select Float on Defined Surface, as shown in the figure below.

Selection floats on defined surface

After clicking OK, you can see the 3D terrain effect, as shown in the figure below.

In the Rectangular Line Layer Properties dialog box, select the Base Height tab and select Float on Defined Surface, as shown in the following figure.

Basic height setting

After clicking OK, the elevation attribute can be added to the rectangular line, as shown in the figure below.

Also in the layer properties dialog box, select the Stretch tab, check Stretch the elements in the layer, set the stretch value to -755, and select the stretch method to add it to the maximum height of each feature, as shown in the figure below shown.

After clicking OK, you can see that the three-dimensional "base" has been made, as shown in the figure below.

Add satellite image

Load the satellite image, also open the layer properties dialog box, select the basic height tab, and choose to float on the custom surface, as shown in the figure below.

set base height

In order to ensure that the satellite image is displayed normally, you need to select the Symbology tab, select None for Stretch, and uncheck Apply Gamma Stretch, as shown in the figure below.

After clicking OK, you can see the 3D map with the satellite image added, as shown in the figure below.

The above is a detailed description of how to use ArcGIS to make a 3D topographic map, mainly including functions such as data source, preprocessing data, stretching data, and adding satellite images.
