Dear experts,
I would be very thankful to receive your help/support/suggestion for solving my following problem. I'm using ArcGIS 10.1 with Spatial Analyst and 3D Analyst(no ArcInfo license) and Arcview 3x (still for many plusses).
I have a raster file- 30m X 30m River netwok cells. I have identified some hot spots i.e. few consecutive river cells at different locations. On the other hand, I have 5 rasters (same as river network) having unique value in each of these rasters.
Now, what I need is the value of these 5 rasters at the location of the hot-spots (the identified few consecutive river cells) in a tabular form. i.e. a table which gives me the location of these hot spot cells (even one central location is ok) and the coressposnig value at these locations from the 5 rasters.
How can I do this? Your suggestion is highly appreciated.
Many Thanks!

Pawan did you try the suggestion in your previous post?

Or are you going off on a different track now?
That should give you the values and if you need to derive the points, then you can convert the raster to points if there is a smattering of locations, or if you have few areas, then doing it in an edit session would be the quickest.
Dear Dan,
I did not know how to close teh earlier post and so following your suggestion i reposted my query in this another thread.
To extract values from the 5 rasters to my main raster (which has few identified hot spots of few successive cells at many places), as you have sugessted I first tried to convert the hot-spots raster to points, but after some processing it stops with 2GB shapefile limit and I'm stucked there as I think without having shape file I cannot have teh required table.
How to tackle? Please suggest..
an image would help.... that is why I suggested that you produce the point file manually if you only have a handful of locations. I suspect you tried to convert your whole raster to points which will dismally fail. It is hard to suggest a course of action without seeing what you are dealing with.
