Problems Loading images (ArcGIS 8.x Version)
A message box appears when you try to load images saying
"There is no Image for this theme in your area"
A red exclamation mark appears next to the image when it's
loaded, and it does not display
The images I have do not show up as options in the Data Viewer menu
Possible Reasons\Solutions:
A message box appears when you try to load images saying
"There is no Image for this theme in your area"
If you get the message saying "There is no Image for this theme in your area" it means that the program
cannot find the image or the image catalog, usually becasue of misplaced or misspelled folders and/or files.
- First make sure that you have the image catalog and or the image(s)
for what you selected. All the different types of imagery appear in the
Data Viewer menu, but they will only work if you ordered that specific
type of image. You cannot load the half-meter color orthophotos if you
only ordered the USGS topgraphic maps.
NOTE: If you ordered a statewide set of images (excluding black
and white mosaic orthophotos, coastal color mosaic orthophoto, NOAA and
USGS mosaic images) and would like to use them with the Data Viewer,
you will have to download the corresponding image catalog table (as the
existing image catalog on the CDs are meant for coverages instead of
the currrent shapefiles).
To download the most recent image catalog(s) go to: Download Image Catalog(s)
- Make sure you have the proper folder structure(\ArcGIS8 and \gisdata together in a folder) and are storing the image catalog
and images in the correct folder(s).
Folder structure for the various image types:
| Half-Meter Color Orthos Mosaics (MrSID) with image catalog: |
\gisdata\Images\coq2001halfmsidm\COQ2001HALFMSIDM_NOENV.dbf |
| Half-Meter Color Orthos (MrSID) with image catalog: |
\gisdata\Images\coqhsid\COQHSID_NOENV.dbf |
| MassGIS BW Orthos (Half-meter SIDs) with image catalog: |
\gisdata\Images\halfmsid\ HALFMSID_NOENV.dbf |
| MassGIS BW Orthos (One-meter SIDs) with image catalog: |
\gisdata\Images\oq1sid\OQ1SID_NOENV.dbf |
| One-Meter Color Orthos (MrSID) with image catalog: |
\gisdata\images\coqhd1sid\COQHD1SID_NOENV.dbf |
| USGS Topographic Maps (Multiple MrSIDs) with image catalog: |
\gisdata\Images\quadsid\QUADSID_NOENV.dbf |
| USGS Topographic Mosaic Images (MrSID) no image catalog: |
\gisdata\Images\QUADSIDM\USGS.SID |
| USGS Topographic Maps (Multiple TIFFs) with image catalog: |
\gisdata\Images\usgs\USGS_NOENV.dbf |
| One-Meter Coastal Color Orthos(1:10,000 MrSID) no image catalog: |
\gisdata\Images\COLOROQ\COQ1_mosaic_30.sid |
Once the program can locate either the image catalog (for multiple
images) or the image file itself (for a single image), then the message
will no longer appear.
A red exclamation mark appears next to the image when it's
loaded, and it does not display
When you load images into the Data Viewer, there will be a red exclamation mark next to the layer,
and it will not draw. Unfortunately the image files keep the original hard coded path (due to a bug in the ESRI software,
which is currently being fixed) to image catalog lyr files. So the files do not know where you have saved the data.
To get around this you will have to reset the data source to the image catalog and resave the lyr file.
- Load the Image catalog, either with the Data Viewer (getting the red exclamation mark), or with the regular
Add Data button within ArcMap. All image catalogs are located under \gisdata\images\(image folder name).
Make sure you pick the Image catalog, that ends with “_NOENV.dbf”, the other image catalog in the folder is for ArcView 3.x
| MassGIS BW Orthos (Half-meter SIDs): |
\gisdata\images\halfmsid\ HALFMSID_NOENV.dbf |
| MassGIS BW Orthos (One-meter SIDs): |
\gisdata\images\oq1sid\OQ1SID_NOENV.dbf |
| Half-Meter Color Orthos (MrSID): |
\gisdata\images\coqhsid\COQHSID_NOENV.dbf |
| Half-Meter Color Orthos Mosaics (MrSID): |
\gisdata\images\coq2001halfmsidm\COQ2001HALFMSIDM_NOENV.dbf |
| One-Meter Color Orthos (MrSID): |
\gisdata\images\coqhd1sid\COQHD1SID_NOENV.dbf |
| USGS Topographic Maps (Multiple MrSIDs): |
\gisdata\images\quadsid\QUADSID_NOENV.dbf |
NOTE: If you added the Image Catalog through the Add Data
button, then the name of the image catalog displayed in the list of
Layers, has the same name as in the image catalog. You might want to
rename to the layer, before saving it. If you used the Add Data button,
then you can skip to step 5, otherwise you will know need to reset the
data source.
-
Right click on the image catalog in the table of contents and select Properties. This brings up the Layer properties window.
-
Under the Source tab Click the ‘Set Data Source’ button.
This will bring up the browse window. You will need to browse
to the associated image catalog from here. Make sure you select the
image catalog with “(name)_NOENV.dbf”.
- Once you select the image catalog press the Add button on the brows
window, and then the OK button on the Layer Properties window. Your
image catalog should now work (you may have to refresh your screen
first).
-
To preserve the correction to the catalog for future use, you will have to resave the lyr file.
Names of the LYR files:
| MassGIS BW Orthos (Half-meter SIDs): |
BW_Ortho_Halfm_Indiv_MrSID.lyr |
| MassGIS BW Orthos (One-meter SIDs): |
BW_Ortho1m_Indiv_MrSID.lyr |
| Half-Meter Color Orthos (MrSID): |
Half_Meter_Color_Orthos_(MrSID_indiv).lyr |
| Half-Meter Color Orthos Mosaics (MrSID): |
Half_Meter_Color_Orthos_(MrSID).lyr |
| One-Meter Color Orthos (MrSID): |
One_Meter_Color_Orthos_(MrSID_indiv).lyr
|
| USGS Topographic Maps (Multiple MrSIDs): |
USGS_Topgraphic_Map_(Indiv_MrSID).lyr |
-
Right click on the corrected image catalog layer and select ‘Save as Layer File’.
Save the LYR in \ArcGIS8\Lyr_files folder with the proper name as listed above, overwriting the existing lyr file.
NOTE: Occasionally, something happens and the lyr file does not
get overwritten. Using your Windows Explorer, you should go to the
\ArcGIS8\Lyr_files folder and refresh the screen, and check the
Modified date of the lyr file you just replaced, to make sure it was
overwritten. If not, then delete the current LYR file associated with
that image type and save it again.
The images I have do not show up as options in the Data Viewer menu
If you have black and white mosaic orthophotos, coastal color mosaic orthophoto, NOAA and USGS mosaic images, there
is no current Image catalog, so you will not be able to load them with the Data Viewer button. You can however
load them using the regular Add Data button in ArcMap.
