I am a GIS Analyst with a background in archaeology, computer science and general electronic tinkering. I generally know enough to get in way over my head and then work my way back out.

That was it. Thanks for the help!

comment Export of a Raster Not Preserving Color
I hadn't thought to open the exported image in something other than ArcMap. If I load it up in Windows Photo Viewer it shows up properly. Is that an indication that the bands are assigned wrong?

Also, I wondered about the re-stretching thing too so I have also tried this with a clipped version of the DEM - and had the same problem there. It seems I'm doing something totally incorrectly, I just have no idea what.

The left is what's on the screen when I run the export, the right is what's on the screen after I add the exported layer to the data frame. I just tried with it set to Min-Max and the edit values box checked - same result.

comment Merging USGS DEMs in ArcMap?
Just to clarify - the mosaic tool you want to use is called "Mosaic to New Raster" and it's located in Data Management --> Raster --> Raster Dataset. The first argument is called "Input Rasters" not "Load Rasters from Workspace" so I'm wondering if you're looking at the wrong tool.

comment Merging USGS DEMs in ArcMap?
If they're ADF files then they're most likely in ESRI grid format - which is a raster format from the start. Have you tried mosaicing the ADF files and skipping the conversion step?

comment ArcMap 10.3 - Anything Python related causes crash to desktop
I've had similar problems while building scripts and having lots and lots of failed runs. One thing I found was that opening up ArcCatalog and clearing out the geoprocessing results made things work again.

comment Methods to determine if traffic accidents happen more frequently along sections of a highway with poor pavement?
A quick google search for 'pavement quality accident rate spatial statistics' (without the quotes) brings up a few interesting results with some example of linear referencing - as suggested by @Maksim below. Sometimes just knowing what to search for will get you rolling.

comment Formatting tags break stacked feature-linked annotations with Maplex
Is the missing + in between the last set of quotes and [field4] a typo from when you brought it here or actually in the code?

I've tangled with similar issues (gis.stackexchange.com/questions/84066/…). Maybe the links in the answer there will be helpful.

And the help from 10.2 about building label expressions that I forgot to add: resources.arcgis.com/en/help/main/10.2/index.html#//…

comment Automating labels with numbers
Definitely. Here's a stackoverflow question about doing just that: stackoverflow.com/questions/1249388/… -- I don't currently have a current enough version of arcgis to help with building a python label expression to do it but it should be possible in versions 10.1 and newer.

comment Bridge not there in Google Earth
Google has gotten pretty crafty at using lidar data (or other high resolution elevation data) to give the appearance of 3D modeled buildings in some areas. You can check to see what is the case in a particular area by checking/unchecking the "Terrain" box in layers and the "3D Buildings".

comment Filemaker interface with QGIS
It's pretty clear - "query the artifact inventory to map the occurrence of items in features to start with and then to work with QGIS analytical tools to see if I can isolate family level information."

That is awesome. Thanks for sharing this, I had no idea this functionality was available with 10.2.

comment Best software for a least cost path analysis
As an archaeologist I feel pretty comfortable saying that ArcGIS is well suited for that kind of work. There's even a built in tool called "Cost Path".

comment How do you hide a feature within a point layer?
+1 For the crazy selection color idea. Ridiculous hacks like that can only be the product of a frustrated ESRI user.

comment Postgresql table won't display in QGIS 2.2
The script was very helpful, I appreciate you sharing it! I don't have a ton to do but I was unsure of how to alter the table correctly. I was able to figure it out from your code - again, many thanks!

comment Postgresql table won't display in QGIS 2.2
I'll just be honest and say I don't know what that is... A link for instructions perhaps? I'm running Postgres 9.1 as part of the OpenGeo suite.
