How do I create an elevation map in ArcGIS?
Procedure
- Navigate to System Toolboxes > Spatial Analyst Tools > Interpolation > Topo to Raster.
- Select the contour layer as the input feature data.
- Specify the location of the output surface raster.
- Set the output extent the same as the contour layer’s extent.
- Click OK. A raster layer is created from the contour.
How is elevation data captured?
One of three types of digital sensors typically collect data that can be used to derive elevation measurements – optical imaging sensor (frame camera / push broom scanner), synthetic aperture radar (SAR) sensor, or laser scanner (also called LIDAR) sensors.
What is a profile graph?
A profile graph is one of the charts available in ArcGIS Pro. Profile graphs show change in elevation of a surface along one or more lines. Profile graphs can help you assess the difficulty of a trail or evaluate the feasibility of placing a rail line along a given route.
How is elevation profile calculated in ArcGIS Pro?
The profile is calculated using the ground elevation surface in a map (2D) or a scene (3D), and unlike other exploratory analysis tools, the values are derived from the data sources for the elevation surface rather than the view’s level of detail. The tool requires a line to generate the elevation profile.
Why do you need a profile graph in ArcGIS?
Profiles show the change in elevation of a surface along a line. They can help you assess the difficulty of a trail or evaluate the feasibility of placing a rail line along a given route. The Profile Graph tools on the 3D Analyst interactive toolbar are used to derive a graphic representation of one or many profiles.
How to create an interactive elevation profile graph?
There are two methods for creating an interactive profile graph: Click in the view to digitize a linear path, and double-click to finish. This is the default method. Generate a profile graph from a selected set of connected line features.
How to create a profile graph from line features?
A profile graph is created from line features without z-values in ArcGIS Pro using the Interpolate Shape tool and the Profile Graph function. Follow the steps below: In ArcGIS Pro, click Analysis > Tools, and search for Interpolate Shape. For Input Surface, select the layer with z-values. In this example, it is the DEM layer named Elevation.
