comment Displaying cross-sections on a web page
We have a budget. I prefer hearing different options so I don't specify the software, although we are using mapguide for the 2d maps and will probably use that for the cross-sections also.

comment In ESRI ArcMap, how do I refer to NaN or ±∞ (special floating point values) in definition queries?
I don't have access to arcgis to test it in this case, but often (in different software packages) you can get rid of these values by running a query like if(a=a,a,-9999).

You probably have introduced a large number of new points. Try using the simplify algorithm in postgis.

comment How to read Autodesk Spatial Data File (.SDF) in PHP
Provide the code used to actually write the SDF. Any code that reads the SDF after you have written the file can pose concurrency problems at some point.
