GIS and Maps - General ← Knowledge Base I don’t know where to begin. Are there some existing maps I can use as a base for my project? Where can I find data for my maps? How do I get access to the GIS data library? I don’t work in the Wildwood complex, how can I get the data updates as they become available? I have a map that has a red exclamation (!) next to some of the layer, and the layer doesn’t draw. What is this and can I fix it? What are relative path names, and when would I use them? What is a spatial bookmark? My MXD file is corrupted and won’t open anymore. Can it be fixed? How do I set my map so the sizes of my labels and marker (point) symbols look right at the final page size I am using? How can I print out the table of attributes?
