ArcGIS Help 10.1 - Raster To DTED (Data Management)

Summary

Splits a raster dataset into files based on the DTED tiling structure.

Usage

There are three levels of the DTED tiling scheme available: DTED level 0, DTED level 1, and DTED level 2.
The input can only be a single band raster dataset.
The output spatial reference will be GCS_WGS84. Each tile's extent is one degree in each direction, plus a half pixel on each edge so adjacent tiles have one column and row of overlap. The output pixel size is dictated by the DTED level, and the data is converted and stored as signed, 16-bit integers.
The DTED format is intended to be used with one band data that represents elevation, so this tool cannot be used for multiband images.

Syntax

RasterToDTED_management (in_raster, out_folder, dted_level, {resampling_type})

Parameter	Explanation	Data Type
in_raster	The input raster dataset. The input must be a single band raster dataset representing elevation.	Raster Layer
out_folder	The output folder where the folder structure and DTED files will be created.	Folder
dted_level	The DTED level to use when creating your tiles. DTED_0 — DTED level 0 specification will be used to split the raster dataset. DTED_1 — DTED level 1 specification will be used to split the raster dataset. This is the default. DTED_2 — DTED level 2 specification will be used to split the raster dataset.	String
resampling_type (Optional)	Choose the resampling method to use when creating the DTEDs. The default is bilinear interpolation resampling. NEAREST —Nearest neighbor assignment BILINEAR —Bilinear interpolation. This is the default. CUBIC —Cubic convolution	String

Code Sample

RasterToDTED example 1 (Python window)

This is a Python sample for RasterToDTED.

import arcpy
RasterToDTED_management("C:/workspace/image1.img","C:/workspace/outputDTED",
                        "DTED_0","BILINEAR")

RasterToDTED example 2 (stand-alone script)

This is a Python script sample for RasterToDTED.
