Importing Images from Express Server into
ArcMap or ArcGIS Image Server
Before you add images catalogued in an Express Server to either ArcGIS Image Server (AIS) or Arcmap, you must "import" those images. Importing an image really means creating an IRL file, a local
file which represents that image (the image itself is very large, and stays in its original location – see
"About IRL Files" on page 15). This is quickly and easily accomplished using the IRLFetch application.
The IRLFetch utility explores an Express Server site and produces a local directory tree containing references (IRL files) to the images published there.
To create and import IRL files for Express Server imagery:
1. Choose Start > Programs > LizardTech > Express Server Plugin for ArcGIS > Import
from Express Server. The IRLFetch utility appears as shown below:
2. Enter the host and port of the Express Server which is hosting the images that you wish to
work with.
3. Browse for or enter the path to the directory you wish to save the imported images in.

Importing Images from Express Server into ArcMap or ArcGIS Image Server
4. It is not necessary to generate world files or AXL files for ArcGIS. However, it is highly recommended that you select the Write AUX files checkbox, as these files contain positioning
and spatial reference information necessary for more consistent behavior in some ArcGIS versions.
5. Click OK.
Once you’ve imported all the IRL files, you can add them to ArcMap documents or AIS Service definitions. (See your ArcGIS documentation for further information.)
NOTE: IRL files based on "NITF Raw" images published on Express Server may be displayed
stretched on the X axis. This can be corrected on the server side by using world files to position the
NITF tiles.

Adding Images to an ArcMap Document
To add images to an ArcMap document:
1. Start ArcMap .
2. Create a new project, or open an existing one.
3. Click on the "+" button to add an image to your document. The Add Data dialog appears as
shown below.
4. Browse to the directory where you imported your Express Server images, and select the
image you wish to add.
5. Click Add, and ArcMap will draw your image.

Adding Images to an ArcMap Document
Troubleshooting
1. If ArcGIS reports "Invalid Raster Format" when viewing an Express Server image, it is most
likely due to one of the following:
A. There has been a communication error with the Express Server. Verify that the Express
Server is running and accessible from your computer (http://<server-ip>:<port>/lizardtech/iserv/browse?style=none).
B. The image has been removed or renamed on the Express Server. In this case, you
should delete the directory containing the IRL files for that server, and run IRLFetch
again (see "Importing Images from Express Server into ArcMap or ArcGIS Image
Server" on page 6).

ExpressView Browser Plug-in User Manual
C. Some other software was installed that unregistered the DLLs required to run the LizardTech Plug-in for ArcGIS. In this case, the best thing to do is to uninstall and reinstall the
plug-in.
2. If you define an environment variable LT_ARCGIS_LOGFILE to be a path to a file, then the
plug-in will generate diagnostic information in the file which will be helpful for troubleshooting.
For example, executing the following commands in the Windows command shell would record
log information in the file C:\irlRaster.log:
E:> set LT_ARCGIS_LOGFILE=C:\irlRaster.log
E:> E:\Program Files\ArcGIS\Bin\ArcMap.exe

Adding Images to an AIS Image Service
Adding Images to an AIS Image Service
All ArcGIS Images Server (AIS) image services are created in ArcMap using the Image Service Definition Editor.
NOTE: The Image Service Definition Editor is part of ESRI’s Image Service Extension, which is
part of ArcGIS Image Server (not ArcMap) but which must be installed on an existing ArcMap installation. See ESRI’s documentation for more information.
To create a new image service:
1. In the Image Service Definition Editor, choose New Image Service from the Image Service menu as shown below.
The New Image Service Wizard starts. This wizard will guide you through the service creation
process.
2. In order to base your service on the Express Server images, pick the IRL file(s) corresponding
to those images. You must specify a Raster Type of “IRL” as shown below. For information
about the other fields in this wizard, see the topic “About the New Image Service Wizard
- 11 -
ExpressView Browser Plug-in User Manual
parameters” in the Help for ESRI’s ArcGIS Image Server.
The output of the wizard is a compiled service definition in an .ISCDEF file that you can add to AIS
using ESRI’s Image Server Manager application. ESRI’s AIS’s Help topic “Publishing image services
with the Image Server Manager” contains more information about this application.

Importing Images from Oracle Spatial into ArcMap
Importing Images from Oracle Spatial into ArcMap
The LizardTech Plug-in for ArcGIS enables users to import image data from an Oracle database into
their ArcView application. With the plug-in, ArcMap users can click a button on the ArcMap toolbar to
browse Oracle Spatial tables and choose one or more MrSID (SID) or JPEG 2000 (JP2) GeoRaster
images to add to their maps.
Importing imagery from a database for use in ArcMap involves connecting to a server and specifying
the GeoRaster table and column from which you wish to import an image, and the image's raster ID.
To connect to an Oracle database and select an image:
1. Click the Add Spatial Express Data button on the ArcMap toolbar. (If you have not yet added
this button, see "Adding the 'Add Spatial Express Data' Button to the ArcMap Toolbar" on
page 14). The Login dialog box appears as shown below.
2. Enter the username, password and database and click OK. The Browse GeoRasters dialog
box appears as shown below.

ExpressView Browser Plug-in User Manual
3. Select a GeoRaster table and GeoRaster column from the drop-down menus. The GeoRaster
Objects field is populated with a list of available GeoRaster images from the specified column,
sorted by Raster ID. Info for each listed item includes its Raster Data Table and any associated descriptive name. (Note: Only JP2 and SID GeoRaster images are listed. Images in
other compression formats, including "NONE", are not shown.)
4. Select one or more GeoRaster images from the GeoRaster Objects list.
5. Optionally, select the Prompt for Password Before Opening Images checkbox. With this
option the password is not stored locally, which means the user must supply it each time the
map is opened (see "About IRL Files" on page 15). By default this checkbox is not selected.
6. Also, note that the "Write (overwrite) Aux file" check box is selected by default. Unless you
encounter specific reasons to disable this, LizardTech recommends you leave this option enabled. This improves interoperability with some versions of ArcGIS.
7. Click OK.
Adding the 'Add Spatial Express Data' Button to the ArcMap Toolbar
The LizardTech Plug-in for ArcGIS includes an extension that enables you to import images from Spatial Express.
Before being able to use the “Add Spatial Express Data” extension to ArcMap, you must add a button
for the plug-in functionality to your ArcMap toolbar. This is very easy to do; once you install the plug-in
the "Add Spatial Express Data" functionality already exists as a custom command. All you have to do
is select it and drag it onto your toolbar to create a button.
- 14 -
Importing Images from Oracle Spatial into ArcMap
To add the button to your toolbar in ArcMap:
1. From the Tools menu select Customize.... The Customize dialog box appears.
2. Select the Commands tab.
3. From the Categories list on the left select File. A list of available commands appears on the
right.
4. Click on the Add Spatial Express Data command and drag it to the desired location in your
toolbar.
5. Click Close.
About IRL Files
NOTE: The following discussion assumes a context of Oracle Spatial images being accessed via
Spatial Express, but IRL files are also used by Express Server.
When you select a GeoRaster image to add to your map, an IRL file is written locally to a preconfigured directory. If you select more than one GeoRaster image, an IRL file is created for each
one. The IRL file contains the connection information and the identifying Raster Data Table/Raster ID
key for the selected GeoRaster in the Oracle database. To avoid filename collision, each file is also
named using a combination of the database connect identifier, the Raster ID and the Raster Data
Table. IRL files are written to a folder in the current user's Application Data directory. This folder is not
configurable.
Once the IRL file is created, it is added to your map. The image is then rendered by the Raster Data
Object component, which is called upon by the ArcObjects framework to position and provide pixels
for Spatial Express images referenced in IRL files.
If the password for a GeoRaster image is stored locally, users can later open the map without entering the password. By default the password is stored reversibly hashed so that it is not readable in
plain text. If the password is not stored, users must supply the password each time they restart ArcMap and open the corresponding map. You may choose not to store the password locally by selecting
the "Prompt for Password Before Opening Images" checkbox on the Browse GeoRasters dialog box
(see "Importing Images from Oracle Spatial into ArcMap" above).
For more information see "Changing an Image's Background Color Via an IRL File" on page 16.

ExpressView Browser Plug-in User Manual
Changing an Image's Background Color Via
an IRL File
You may change the background color of an image viewed in ArcGIS by opening the IRL file in a text
editor and manually adding a background flag ("bg") along with the hexadecimal RGB code for the
desired color.
For example, the following text from an IRL file specifies an Express Server, a catalog, and an image,
but uses no background flag, so the image will be rendered with the default (black) background:
http://demo.lizardtech.com:80/lizardtech/iserv/getimage?cat=Seattle&item=/iservcatalog-index
A blue background is specified by appending the background flag with the code for blue, as follows:
http://demo.lizardtech.com:80/lizardtech/iserv/getimage?cat=Seattle&item=/iservcatalog-index&bg=0000ff
NOTE: Changing the IRL for an image does not change the original image data stored on an
Express Server or Oracle Spatial database.
