Hi Priyamvada,

is it essential for you to obtain the Field ID? As far as I remember, the resultant raster will come with a new ID set (Row ID).is it missing in your case?

One raster is a Euclidean Distance raster dataset and another is a raster of polygon features (I converted a shapefile to ratser). I need to combine to get a new data set of having values from both these rasters. But I need to have the polygon features (I have named it as PARCEL ID) intact, so I can add some other values to it. But the resultant raster has some missing PARCEL IDs. How to solve this?

1. once you convert feature to raster, there will be some changes. you can not have 100 % intact features in the raster.

2. did you set the data type properly?the PARCEL ID was included in the feature table or you joined it separately? if so in that case the data type has to be set carefully.

3. are you willing to add values to the raster?or feature?

Hello,

I realize, the problems starts with the rasterizing of the features file. When I rasterize the features map, some IDs are missing which later on cause missing rows in the combine function result. So I suppose adding another field with new set of ID may be a solution. Or can you suggest a better solution?

once you have rasterised try adding the ID field. what i have yet not understood is why you need this ID in your final combined output?

I need the ID because I then export the attribute table in dbf format to do some calculations, and then join it with another attribute table, with identical ID. So when I am doing the join, some rows are vacant, because of the missing rows from the resultant combine attribute table. But I also found the problem with it. There was an enviroment setting I was missing. Now it is fine. The raster table has mising rows, but that corresponds with missing rows in all other tables. So it is okay now, I dont have vacant rows. Thanks for your help :)

Welcome

What setting did u put in order?

In the Environments settings.. In "Raster Analysis", I mention the cell size same as the ratser layer with is one of the layers in the combine function. After I made this specification, the problem of vacant rows in the later steps is gone. Earlier I was specifying only the Extent and Coordinates in this Enviornments window. But I learnt that Raster Analysis is also important.

I do not know how much experience you have wit ArcGIS, but since this is only a second experience for me, it has been a learning. I hope you too did learn something from this discussion.

Thank you for showing interest in this discussion :)

:) it was my pleasure too. I have been using this for quite some time and currently working with network...

Deviating from the topic, I am curious to know what kind of GIS work is happening in ISI? And do they recruit researchers only with statistical background, or other fields are also welcome?

They do but mostly with stats, biotech, microbio etc.other thn that math and economics r there.they do advertise from time to time.keep a track of their website.
