Terrain analysis is done to collect and interpret the topographic features of bare terrain surfaces and, in most cases, link terrain properties to the natural or man-made environment. It usually employs elevation data, usually in conjunction with other geospatial information such as slope and direction, to describe the landscape, for basic visualization, modeling, or to support decision making.
With just a click on a button, Plex-Earth 5D offers this functionality for designers or topographers to perform such analysis and gain more insight on a terrain.
This tutorial will show the steps on how to conduct a terrain analysis.
To start with, on the Terrain Panel of the Plex-Earth 5D ribbon, click on Terrain at the bottom part.
Click on Analysis and on the dropdown, choose Analysis again.
Plex-Earth 5D will prompt the user to select the terrain object to conduct an analysis of. It can be a terrain mesh, contours, or elevation points. Performing an analysis on a terrain mesh will be considered for this tutorial.
Choose which category of analysis to perform. Plex-Earth can show three types of terrain analysis: Elevation, Slope, and Direction analysis. Select which one to perform via the command line.
The steps to conduct either of the three analyses will be similar. For this tutorial, conducting an elevation analysis will be done.
Plex-Earth will then ask how to specify the ranges - Auto or Custom.
- Auto - Plex-Earth will automatically calculate the interval of ranges for the user.
- Custom - Choose this to set different minimum and maximum values for each range. Set the minimum value of the current range to 1 unit above of the minimum value of the previous range. Example, if the maximum value of Range 1 is 100, set the minimum value of Range 2 to 101.
Once done, define the number of ranges to consider for the chosen analysis.
Pick the method on how to visualize the range colors - either Gradient or Manual.
- Gradient - This option will show a smooth transition from the two colors that will need to be selected. The first color corresponds to the color of the range with the lowest elevation value and the last color corresponds to the color of the range with the highest elevation value.
- Manual - This option will allow the user to choose his preferred color for each range.
If the color codes of the preferred colors is known, type it in the command line and hit the Enter key. Otherwise, click on the Dialog option located in the command line and choose the desired color from the color dialog box that will pop up.
After choosing the colors, select how to display the analysis - either as 2D Solid, 3D faces, or Mesh, whichever is the most fitting to one's needs.
For this tutorial, the selected options is the 3D faces display and the resulting image of the analysis is displayed below:
Through utilizing this feature, designers can not only perform advanced terrain analysis in the simplest and most efficient way possible but also gain valuable data and insights of a terrain from the stunning visualization produced by Plex-Earth 5D.
