A map of Nebraska showing population (the number of persons) by county. Please pardon the error: the title should not have the word "density"; I will need to upload a corrected version.

I was able to bring in a jpg and work off of it. I tried to convert the pdf to jpg but could not figure out how (I am hoping I can print it and scan it, perhaps at the community library). David I made a mistake there, you cannot bring PDFs in. However, it usually is a simple matter to convert the pdf to a jpg(or other raster type) and bring it in.

Thank you for your response. The information/links you provided seemed to help me do what I wanted to do. David You can bring in images and pdfs from the catalog in ArcMap. However, if they have no spatial reference, you must georeference the images, so they match the projection and scale. Some good links to help you georeferencing. http://resources.arcgis.com/en/help/main/10.2/index.html#//009t000000mn000000 http://resources.arcgis.com/en/help/main/10.2/index.html#/Georeferencing_toolbar_tools/009t000000mp000000/

Thanks for the reply. I am joining both text and numeric attributes. I am new to this level of GIS, so I don't know what "join functionality" is; I am joining the many attributes in my Excel to the many different attributes in my layer using a common attribute: jurisdiction name. The first time I did the join I saw my data, but not the attribute names (eg "population"). When I tried it again I got the attribute names, but the excel data was all converted to "null" in the layer table. I figured perhaps there is an excel file extension (xls, xml) that "talks" to GIS the best. When you say you like to use "real-live database tables", what do you mean by that? David What's the best.... Always a tough question to answer. What type of attribute are you joining on (text, numeric, etc?) What is the join functionality: 1 to 1 or Many to 1? Personally if it's anything but 1:1, I use a relate instead. What is giving you the impression that the join isn't working properly? Finally, and again just personally, I prefer to use excel for my invoicing and other book keeping procedures, but I use real-live database tables for my GIS work. YMMV....

What is the best format for an excel spreadsheet to join the data to a GIS layer? I have the home use license for desktops. I put data into an excel spreadsheet, imported that spreadsheet into my GIS on ArcMap, and joined the data into a layer that I had created. However, it did not seem to join properly judging by what I saw on the layer's table. Any suggestions?
