Sorry my apologies for the lack of info (still new to the forum stuff)
So we use ArcMap 9.3
and yes by layerfile I mean when you save it as a specific symbology is there a way to have it update automatically?
EXAMPLE:
Let's say you have a layerfile called "Cities" and you have the symbology set to show specific cities with a specific linetype, colour, shape, etc.
Now let's say you have that same "Cities" file used in 3 or 4 mxds (using the layerfile which saves the symbology you originally saved it as) and you decide 'oh I need to update or change something in my symbology for that file.
Instead of changing it in all 3-4 mxds is there a way to change it in one and for it to automatically change it in the others without having to go in them?? Kind of like when you edit a shapefile once it's edited it shows up on all mxds not just the one (which is what the layerfile does)
I hope that makes sense :s
Thanks
I think we need a little more details...
What software do you use? Mentionning the Layer File, I thought ArcGIS, but they could be use by other software...
What do you want to update specifically? The symbology? You meant that if you change, for example, the width of a line in a map, the same feature will be modified as well in your other maps? Is this something that could be done with a MapBook? You change your symbology in the TOC, all the maps will change as well... If it's the attributes, you could always have a external database like a MySQL database? If you change your values, when you open your maps, the symbology will update automatically.
For the labels, there's MapText, but it's quite expensive and it didn't work a bit when we tried it (it was for an thematic atlas).
