Convert JP2 Data to IMG with ESRI ArcGIS Python Scripts

These directions assume that ArcGIS 10 or 10.1 have already been installed with their default install locations.
1aObtain JP2 Data: Step 1
The primary method for downloading The National Map (TNM) raster JP2 (High Resolution Orthoimagery (HRO) and National Agricultural Imagery Program (NAIP)) type of staged products is by using the new TNM download client ( Zoom to the area of interest. Select "Imagery - 1 foot (HRO)" or "Imagery - 1 meter (NAIP)" from the Datasets section on the left (1), then click on the "Find Products" button (2) to bring up the available products.
1bObtain JP2 Data: Step 2
When the Available Products window appears, click on "Download" to download the JP2 in a zip file. Once downloaded, unzip the file locally, making note of the location.
2Obtain USGS Raster Conversion Scripts
A set of scripts for converting raster staged data is available at USGS_Raster_Conversion_Scripts. These should be downloaded and unzipped locally. (These directions are part of the how to documentation in that archive.)
3aOption 1: Drag and Drop JP2 Download Folder
The ArcGIS_Convert_All_JP2_2_IMG.bat script takes a folder name as input and recursively scans that folder for all TIF files and attempts to create an IMG for each. In Windows Explorer, when you drag and drop a folder onto a batch file, the folder path is passed as the parameter to run that batch file with. Doing this produces an IMG in that same folder as the JP2 data. The resulting image(s) will have the name ArcGIS_JP2_2_ANY.img.

In order to use this method, download the Esri ArcGIS scripts into a user-controlled directory with write permissions. Drag and drop the original JP2 file from the same directory that the conversion script is located in.
3bOption 2: Run the ArcGIS_JP2_2_ANY.bat from the Command Line
The ArcGIS_JP2_2_ANY.bat file uses a TIF file location for the first parameter which is the source to convert. This script will not recursively scan the sub-directories to find the data, so the path must point to the actual JP2 file. A second parameter that is optional allows you to specify the path and name of the output JP2 file.

Since the second parameter is optional, the easiest way to run this is to drag and drop the ArcGrid data folder onto the batch file. The catch is that the default conversion is to IMG format. This means to get a JP2 output, we need to specify the second parameter by running this from the command line. The script uses the file extension of the second parameter to determine the correct output type. The directions for using this script are presented below:
USAGE: ArcGIS_JP2_2_ANY.bat <JP2 Input File> [Output File Name]
<JP2 Input File>(REQUIRED) This is the relative or full path to the JP2 file that contains the source data.
[Output File Name](OPTIONAL) This is the relative or full path to the output file that will be created. If this is not set, it will attempt to make a sub-folder under the current directory called ANY_Output, and a file in that folder called ArcGIS_JP2_2_ANY.img. The default format is GeoTIFF, but if a different extension is specified then it will use the format specified by the extension.
