Greetings, To exclude duplicates on load you need to set the property in IAddRasterParameters: IAddRastersParameters AddRastersArgs = new AddRastersParametersClass(); ... setup crawler etc... // Exclude duplicates AddRastersArgs.DuplicateItemsAction = esriDuplicateItemsAction.esriDuplicateItemsExclude; Hope this helps.

Greetings, When you say you want the pixel values, what exactly do you mean? You can use the identify tool to see the pixel value at a given location. If you need points then you can use the raster to point geoprocessing tool. Robert ... View more

Greetings, If you did an "update georeferencing" then the spatial reference should be retained in the image. The copy raster tool also has the nodata parameter that you can set to 0 to avoid black borders. Generally that should work if your input already has the spatial reference. Robert ... View more

Hi Sam, Have you tried using the raster catalog in ArcScene? I would also suggest building an unmanaged raster catalog. You can additionally play with the display properties if you do not want to see the wireframe. If you have 10.0 I would suggest using the mosaic dataset as it has many more options for you to manage your data. Robert ... View more

Greetings, In order to rectify your images as a new output you should be able to do a simple copy raster (SaveAs) to a new dataset. That should write a new dataset with the georeferencing information. Orthorectification is the process to remove elevation displacement from the image by using an elevation dataset with your imagery. It doesn't seem that this is what you're looking for. Hope this helps. Robert ... View more

Greetings, Even floating point data shouldn't be an issue. Simply calculate statistics on the floating point dataset and then the data should display fine. Robert ... View more

Greetings, One thing that has worked for me pretty well was using Add-Ins (in 10.0). You can check out how they work here. Robert ... View more

Hi, Can you try to calculate statistics in ArcGIS on the files in question? It sounds like the files are read in as floating point data. Robert ... View more

Hi Sam, When you say "merge" did you simply try to use the raster catalog or did you try to mosaic the datasets into a single dataset. If it is the latter, then be aware that ECW is highly compressed which means you need a lot of disk space to write out the new file. Robert ... View more

Greetings, Yes, the composite bands tool will accomplish this. You can drill into the raster and input the desired band to the tool. Robert ... View more

Greetings, All you should have to do is drag/drop the jp2 file into ArcMap. robert ... View more

Greetings, what kind of errors do you get when trying to use color balancing? Did you see the help topic? Also make sure you have the correct statistics built for the MD records. robert ... View more

Hi, I think the general suggestion is to color correct before building overviews. Then when you build the overviews they will reflect the color correction. If you already have good results from color correction, then remove the overviews and rebuild them. That should do the trick. I don't know of a way to specifically correct the overviews themselves.

Hi Jeff, Did you see the VB/.NET sample? Does that help? Robert ... View more

Hi Simran, If you set the spatial reference of the data frame to the desired spatial reference (Here UTM Zone 43N) then, after update georeferencing, you should have that spatial reference in the dataset. What is your map data projected to - the data that you are georeferencing to? Video Hope this helps. Robert ... View more
