Map To KML

This tool converts a map document into a KML file containing a translation of Esri geometries and symbology. This file is compressed using ZIP compression, will have a .kmz extension, and can be read by any KML client including Explorer for ArcGIS, ArcGlobe, and Google Earth.

1.    Map Document

The map document to convert to KML.

2.    Data Frame

The data frame of the map document to convert to KML.

3.    Output File

The KML file to write. This file is compressed and will have a .kmz extension. It can be read by any KML client including ArcGIS Explorer, ArcGlobe, and Google Earth.

4.    Map Output Scale (optional)

The scale at which to export each layer in the map document. This parameter is important with any scale dependency, such as layer visibility or scale-dependent rendering. If the layer is not visible at the export scale, it will not be included in the created KML file. Any value, such as 1, can be used if there are no scale dependencies.

Beginning with 10.1 Service Pack 1, this parameter has been enhanced to accept the value of 0. A scale value of 0 is an override switch to ignore scale dependencies set on the layer. Any actual scale value will produce a KML with the layers visible at the given input.

If exporting a layer that is to be displayed as 3D vectors and the Return single composite image parameter is unchecked, you can set this parameter to any value, as long as your features do not have any scale-dependent rendering.

Only numeric characters should be entered; for example, enter 20000 as the scale, not 1:20000 or 20,000.

This parameter does not control the output resolution of a raster.

5.    Clamped features to ground (optional)

1. Checked—You can override the Z-values inside your features or force them to be clamped to the ground. You should use this setting if you are not working with 3D features or have features with Z-values that might not honor values relative to sea level. This is the default.
2. Unchecked—The output KML file will be created, which respects the Z-values of features. Your output KML features will be set to the absolute value, which could place features below the earth's surface in some KML clients. Most KML clients allow you to set the display mode for features when viewing the KML file.

Most KML viewers set absolute as sea level and draw features with elevation (Z-values) based on that value.

6.    Return single composite image (optional)

1. Checked—Directs the output KML file to contain only a single image that composites all the features in this map into a single raster image. The raster is draped over the terrain as a KML GroundOverlay. Select this option to reduce the size of the output KMZ file. When you check this box, individual features and layers in the KML file are not selectable. Also, the next parameter, Convert Vector to Raster, is ignored.
2. Unchecked—Layers will be returned separately in the KML file. Whether the layers are returned all as rasters or as a mix of vectors and rasters is determined by the next parameter, Convert Vector to Raster.

7.    Convert Vector to Raster (optional)

1. Checked—Converts each vector layer in the map into a separate raster image in the KML output. Normal raster layers are also added to the KML output. Each output KML raster layer is selectable, and its transparency can be adjusted in certain KML clients.
2. Unchecked—Preserves vector layers in the map as KML vectors.

8.    Extent to Export (optional)

The geographic extent of the area to be exported. Either define the extent box (in the WGS84 coordinate system), or select a layer or dataset that defines an extent.

9.    Size of returned image (pixels) (optional)

Size of returned image in pixels. Defines the vertical and horizontal resolution of any rasters in the output KML document. Use this parameter with the DPI of output image parameter to control output image resolution.

10. DPI of output image (optional)

 Defines the device resolution for any rasters in the output KML document. Typical screen resolution is 96 dpi. If the data inside your map supports high resolution and your KML requires it, consider increasing the value. Use this parameter with the Image Size parameter to control output image resolution.

ASCII to Raster

How to use ASCII to Raster Tool in ArcToolbox ArcMap ArcGIS??

ASCII to Raster

Path to access the tool

:

ASCII to Raster Tool, To Raster Toolset, Conversion Toolbox

 

ASCII to Raster

Converts an ASCII file representing raster data to a raster dataset.

1.    Input ASCII raster file

The input ASCII file to be converted.

2.    Output raster

The output raster dataset to be created.

When not saving to a geodatabase, specify .tif for a TIFF file format, .CRF for CRF file format, .img for an ERDAS IMAGINE file format, or no extension for an Esri Grid raster format.

3.    Output data type (optional)

The data type of the output raster dataset.

1. INTEGER—An integer raster dataset will be created.
2. FLOAT—A floating-point raster dataset will be created.

DEM to Raster

DEM to Raster

Path to access the tool

:

DEM to Raster Tool, To Raster Toolset, Conversion Toolbox

 

DEM to Raster

Converts a digital elevation model (DEM) in a United States Geological Survey (USGS) format to a raster dataset.

1.    Input USGS DEM file

The input USGS DEM file. The DEM must be standard USGS 7.5 minute, 1 degree, or any other file in the USGS DEM format. The DEM may be in either fixed or variable record-length format.

2.    Output raster

The output raster dataset to be created.

When not saving to a geodatabase, specify .tif for a TIFF file format, .CRF for CRF file format, .img for an ERDAS IMAGINE file format, or no extension for an Esri Grid raster format.

3.    Output data type (optional)

Data type of the output raster dataset.

1. INTEGER—An integer raster dataset will be created.
2. FLOAT—A floating-point raster dataset will be created. This is the default.

4.    Z factor (optional)

The number of ground x,y units in one surface z unit.

The z-factor adjusts the units of measure for the z units when they are different from the x,y units of the input surface. The z-values of the input surface are multiplied by the z-factor when calculating the final output surface.

If the x,y units and z units are in the same units of measure, the z-factor is 1. This is the default.

If the x,y units and z units are in different units of measure, the z-factor must be set to the appropriate factor, or the results will be incorrect. For example, if your z units are feet and your x,y units are meters, you would use a z-factor of 0.3048 to convert your z units from feet to meters (1 foot = 0.3048 meter).
