Interpolation

• The interpolation toolsets aims to fill in cells with unknown values to output continuous raster data. Examples of these outputs are digital elevation model (DEM), temperature and barometric maps, land price maps and other continuous raster data.
• All the tools of this group are located in the 3D Analyst Tools box within the Raster Interpolation Toolset and they have been explained. To access the tools, click on each of the following tools:I

1. DW:

Interpolates a raster surface from points using an inverse distance weighted (IDW) technique.

2. Kriging:

Interpolates a raster surface from points using kriging.

3. Natural:

Interpolates a raster surface from points using a natural neighbor technique.

4. Spline:

• Interpolates a raster surface from points using a two-dimensional minimum curvature spline technique.
• The resulting smooth surface passes exactly through the input points.

5. Spline with Barriers:

Interpolates a raster surface, using barriers, from points using a minimum curvature spline technique. The barriers are entered as either polygon or polyline features.

6. Topo to Raster:

Interpolates a hydrologically correct raster surface from point, line, and polygon data.

7. Topo to Raster by File:

Interpolates a hydrologically correct raster surface from point, line, and polygon data using parameters specified in a file.

8. Trend:

Interpolates a raster surface from points using a trend technique.
