- 3Except you can't do analysis or selections on basemap layers IIRC.blah238– blah2382012-10-24 04:50:47 +00:00Commented Oct 24, 2012 at 4:50
- 4Suspect that could be gotten around by having second layer in TOC pointing at same source and not a basemap layer, which is usually turned off but can be displayed when required for analysis or selection.PolyGeo– PolyGeo ♦2012-10-24 05:34:46 +00:00Commented Oct 24, 2012 at 5:34
- PolyGeo - thanks for answer. I tried baselayer and indeed a major performance improvement is when "zoom to layer" is clicked, the file does not render from scratch. The workaround you suggest given blah238's comment would perhaps work from some projects, but I found an addtional thing that limites the use of baselayer is that you cannot visualize the dbf using any symbology. With this limitation I might as well generlize the file for reference (not a baselayer), then unhide the "real" layer when needed. Not really a great solution.. I'll be voting "pyramids" idea as you suggest!youzer– youzer2012-10-24 19:41:46 +00:00Commented Oct 24, 2012 at 19:41

``` - put returns between paragraphs

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. arcgis-desktop), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
