Surface Analysis Map in ArcGIS
Surface Analysis represents height values for an Elevation surface or structure of a Surface. In this Tutorial Learn how to create different types of Surface Analysis map in ArcGIS.
Now perform to 6 Surface Analysis model.
Launch ArcGIS software, then open the Toolbox, ArcToolbox window is appears to expend Spatial Analyst Tools, then expend the Surface subgroup. All are surface analysis models available in this group. Select and double click it.

Table of Contents
Aspect
The Aspect identifies the downslope direction of the maximum rate of change in value from each cell to its neighbors. Now Aspect can be thought of as the slope direction.
Open Aspect, Aspect window appears select Input Raster and Output Raster and click ok.


Contour
Contours are line features that connect locations of equal elevation value in a raster dataset. That represents continuous phenomena such as elevation.
Open Contour, Contour window appears select Input Raster, Output Features, and most important input contour interval(ex. 100) click ok.


Curvature
Curvature represents, determine the acceleration and convergence of flow in a drainage basin to better understand topsoil erosion.
Open Curvature, Curvature window appears select Input Raster and Output Raster and click ok.


Hillshade
Create a Hillshade relief from an elevation surface raster by considering appropriate illumination source Angel and Shadow.
Open Hillshade, Hillshade window appears select Input Raster and Output Raster and click ok.


Slope
The Slope represents the variations of the landscape. You want to find the areas most at risk of landslide based on the angle of steepness in an area.
Open Slope, slope window appears select Input Raster and Output Raster (you can choose output measurement- Degree or Percent) and click ok.


Viewshed
A Viewshed is useful when you want to know how visible objects will be. For instance, you might want to find the location with the most expansive view in an area. Because you want to choose the best location for an observation tower or scenic overlook.
Perform Viewshade first create a Point Vector file and point out any particular place in your Raster data. Open Viewshade, Viewshade window appears select Input Raster, Input point feature, and Output Raster and click ok.


Thank you for any other great article. Where else could anyone get that type of info in such an ideal way of writing? I’ve a presentation next week, and I’m on the look for such information.
