I like to explain what I did. Out of many pairs of images with NIR and R bands, I selected one pair of NIR and R bands. I created a model using modelbuilder in a step wise fashion. I invoked three times the raster calculator and in the first one I multiplied Red band with 0.0001 and obtained an output. In the second one I multiplied NIR band with 0.0001 with a resultant output. In the third one I used a formula of (NIR-R)/(NIR+R) using the outputs from the earlier two multiplications and I got NDVI image. My intention was to use this model to calculate NDVI from other datasets consisting R and NIR bands. I created a raster catalog with the datasets for iteration. I tried to iterate the process using "raster" iterator. In the dialogue box I showed the raster catalog as source of the rasters and I ran the model after connecting the NDVI output to the Iterator. I could see a lot of processing and got an image with a same name which was given to the raster catalogue, for example 'Test'. I invoked that 'Test' into ArcMap and I could see a stack of layers with some numbers other than NDVI values when I was inquiring and I stopped at this juncture as I do not know what to do. Help is solicited to complete the process correctly so that I can automate the process of creating NDVI images from hundreds of images.

I am new to such operations. However, I tried to link 'Rasters' as as iterator which I could connect to an output file which was generated after the calculations. But the end product was not what I wanted. Kindly suggest the steps to get the iterations.

I have hundreds of images comprising NIR and Red bands for calculating NDVI which will be used in Time series analysis. I am not familiar with batch processing and I wish to automate the NDVI calculation from these many images. I could create a model using Modelbuilder and got NDVI image from one set of NIR and Red bands and I wish to run this model fro remaining images. But I do not know how to loop this iterate this what do to next. My time will be saved when a batch processing is taken up rather than running this model for every set of NIR and Red bands. I solicit a kind help in solving my problem.

Deal member, I am a new user of ArcGIS. I wanted to export one shape file to coverage using ArcGIS 10. However, it fails to do with an error message, 'Feature class to converge'. Can any one suggest as to how can I overcome this problem? DVK Nageswara Rao
