I am getting error messages when trying to merge three orthophotos using Spatial Analyst. I have been following the recommendations in Forum threads, and I followed the directions in the ESRI support document 20988 "Merge rasters using ArcGIS Spatial Analyst", and I followed the directions in ArcGIS Desktop Help 9.3. I was careful to make sure each orthophoto has a different name. Also, each ortho is made of four files, and those were the same for each ortho: band_1, band_2, band_3, and band_4. I changed the names so that all 12 parts had different names. (12 comes from this equation: 3 orthos x 4 "band" files = 12) This is the first error message I got: ERROR 010316: Unable to open the input grid: C:\USERS\ANNAGL~1\APPDATA\LOCAL\TEMP\Z_Z_Z2 ERROR 010067: Error in executing grid expression. When I go to the folder to see if there are files in there, I found files named "z_z_z2", "z_z_z3", and "z_z_z4", and each of these looks like a darker version of one of my original three orthophotos. I'm not sure what I'm doing wrong, or simply what to do next. Please help if you can - Thanks! Anna

jehall, You hit the nail on the head! Er, you turned my world upside down, and now it works. Basically, you suggested I do what I've been doing but in the opposite order. And it worked. Additionally, ArcCatalog makes so much more sense to me now. Thank you so much! anna

I need to create a parcel layer for a facility I am mapping. I took a screenshot (jpeg) of the parcel layer from a GIS website. I want to draw over the jpeg and turn the lines into a layer. I have already followed the tutorial in my ArcGIS 9 "Using ArcGIS Desktop" manual for "Creating features from a printed or scanned map". This got me as far as having the image (of parcel lines) scaled correctly in my drawing. Next, without a tutorial, I figured out how to draw lines over the image. I'm not sure I did that the best way but anyway, moving on, I need to turn the parcel lines into a layer. It is not currently associated with any layer nor it is a shapefile, and I'd also like to turn it into a shapefile. (If I understand correctly, if you have one, you have the other. A layer is from a shapefile, a shapefile is what you open to get a layer). As you can tell by now, I'm new at this. By the way, I'm using ArcGIS 9.3 Thank you! Anna
