comment Using ArcGIS 10 on a virtual machine with OSX
I ran the ArcGIS 9.4 beta, which was renamed to v10 for release, on VMWare under 64bit XP host. It was quite slow, which I chalked up to running under a VM. However we've since installed v10 natively on 3 of the 4 machines in our unit, running a mix of XP and Win7, and 2 of the 3 are performing horribly, much worse than 9.3 on the same machines. The slowness you are seeing may have little or nothing to do with running in a VM.

comment GIS Certification
the phrase "I am currently enrolled" is repeated. I think the first occurrence is there by mistake and can be deleted :)

comment What strategies, criteria, or rules to use for selecting coordinate systems?
The central point in this is that querying the same location in Albers and UTM yields different numbers, but the location in relation to others is so similar as to render the difference meaningless. Likewise area and distance calculations compared between Albers & UTM are close enough that the differences can be considered statistical noise at this scale. (We commonly deal with features in the hundreds and thousands of Km: Parks, Game Management Zones, etc.)

comment What strategies, criteria, or rules to use for selecting coordinate systems?
@whuber: the word "arbitrary" here is meant to convey the idea that we, the humans, are imposing a mental construct onto the reality out there. If we were using for example, a base 12 number system, the coordinate system would be completely different yet could describe the world just as well. By no means do I mean to imply it doesn't matter which system is used. In matter of fact, choice of coord-sys is often the most fundamental decision to be made.

comment Is there a projection issue with the NRC Canada Atlas hydrology data?
Thanks for taking the time to pass on the response from NRC Jakub. I suggest marking this as the accepted answer (yes it's perfectly acceptable to change the accepted answer when a better one comes along, even if it's your own).

comment Add Shapefile now fails :(
it's okay to answer the question yourself, and accept it as answered. Embedding the answer in the question will keep it lingering in the unanswered pool forever.

comment What Makes a Map Beautiful?
The Missippi history series is truly a masterpiece, both for it's cartography and the field work it's built on. Thanks for reminding me about it.

something is broken. I couldn't get the image to work either, even with a manual link.

comment Monster Spatial database server suggestions
"tight budget" together with "monster" is an oxymoron. Better to indicate what the budget is and ask "what's the absolute best I can do with..."

comment Monster Spatial database server suggestions
This is a time sensitive question. In two or three years the answers will no longer be as relevant. Please add something indicating the time period. For example, Monster spatial database server recommendations (2011) and in body "In 2011 what would be the best configuration..."

comment Simplify shapefile parcel layer
I do wish the answers here were more than one liners though. For example when Mapperz moves his blog to a different service and ESRI stops serving 9.2 help pages the key ideas, the concepts that makes those real "answers", will be lost and all we'll have are highly recommended broken links.

comment Simplify shapefile parcel layer
The answers to the related questions a , b tend to the theoretical and are not arcgis specific. I think we can tolerate a little duplication here.

comment Simplify shapefile parcel layer
this goes to the same page is the same as dassouki's "this might help" link (albeit to a different version. No significant changes from 9.2 to 9.3 though).

comment Control the colors of a shapefile
this is the first I've head of this, sounds interesting. Can you provide more info? For example do the style files need to have the same filename as the shapefile they refer too? and do you use the Style Manager to build them or something else?

comment Are the Canadian National Topographic System (NTS) maps available freely online?
the link Zachary posted goes to the "print ready" CanMatrix files, which are not geo-referenced. There also geotiff CanMatrix files, with collars, here. De-collared, georeferenced and colour balanced CanMatrix - National Topographic Series (NTS) maps scanned at 150dpi - at 250k and 50k scales can be purchased on dvd from MapTown as eTopo for a reasonable price - $100 per province/territory.(No restrictions on re-use and distribtion, standard NRCAN data license)
