comment What are the advantages of interpolation vs raster from point elevations?
I am not clear on what two things you are comparing, but they both sound like interpolation to me.

comment Is it possible to render a large number of shapefiles to a pdf document using Python?
It's recommended that you edit your question to add those kinds of details rather than expound in the comments.

comment Is it possible to render a large number of shapefiles to a pdf document using Python?
Can you give us a better idea of the number of shapefiles, number of features in each shapefile, and (on average) the number of vertices per feature? It sounds like you are just asking way too much of the PDF format.

comment Z-value missing in attribute table of shapefile from ASCII 3D to Feature Class?
Multipoint is an aggregate geometry type, in which many thousands of vertices (points) are stored per row (multipoint). So it will not be possible to extract each Z value without first converting to Point.

comment Z-value missing in attribute table of shapefile from ASCII 3D to Feature Class?
Felix is correct, with Multipoint, the Z and M values are stored per-vertex, of which there may be thousands per multipoint feature, which is an aggregate geometry type. If you want to have Z values in the attribute table, use Point, not Multipoint, and then use Dan's answer to add the Z values to the table.

Please explain how they are different. You've used the same code snippet on both.

If you need to produce and serve lots of derived products, check out this presentation: proceedings.esri.com/library/userconf/feduc11/papers/tech/…

You could also use ASCII to 3D Feature Class and load it into a Terrain Dataset.

comment What's the most common way to join photos with geographic data?
What's the cardinality? One to one, one to many, etc? Also, what properties of the photo relate them to the geographic data, if any? Are they geotagged?

comment What's the most common way to join photos with geographic data?
Could you explain what you mean by "joining", or some example you have in mind?

comment How can I parallelise embarrassingly parallel GIS operations in QGIS python?
Not familiar with multiprocessing in QGIS, but this ArcGIS-specific example may be of some use: gis.stackexchange.com/a/20352/753

comment Best practice to perform raster map algebra in open source web GIS?
"Is there a reasonable way to ..." is a really wordy phrase (where, e.g., "How to ..." works just fine) to put in a question title, so if you can think of a better way to state your question than what I had suggested please do so. Also, I consider the word "software" to include programming APIs and libraries, such as GDAL, so by that interpretation, your reversion of my edit was probably unnecessary. However, do what you wish if you think it clarifies your question.

comment How do updateParameters and updateMessages Interact in a Python Toolbox?
Also I was testing using a script tool rather than a Python toolbox. Maybe there is a difference there, although my gut feeling is there shouldn't be.
