comment What index to use in this situation
Indexing often doesn't mean much when the query is doing a full table scan. The WHERE clause is the most important piece of the puzzle. You can strip it down to a representative sample, but if you leave it out of the question, you are unlikely to get a correct answer.

comment Trouble Creating Raster Catalog in SDE
Please edit the question to include the error you are getting, the operating system you are using, and the exact version of SQL-Server (only 2008R2 is supported).

comment Calculate the coordinates upper right corner from the center
If you edit the question to provide the data you have, the example could use your values. It would also help if you specified which "center" (UR pixel center or raster center).

comment Using Python to shorten polylines of varying lengths by 44% of their original length (or by a value contained in a field)
In what projection is the feature class? (Please edit the question with details requested from comments.) If it's a geographic coordinate system, then determining 56% of the original length might be challenging.

comment Can I create an Oracle Spatial View from a non-spatial table?
You can't create an index on a view, only on a "materialized view" (which is really a table). How many rows are in the table? While creating a dynamic geometry is possible, the performance is not generally going to be adequate for common use.

comment What is the maximum attachment file size in Esri file and ArcSDE geodatabases?
Heap size is an operating system property, not something set by an application. Worse yet, the order of allocation and return can drastically impact the effective limit, so it's not really documentable.

comment Using polygons with libspatialindex
Most spatial indexes just cover the envelope of features, which reduces the complexity, but it also means you may need to do more complex comparisons with the candidates returned by indexes.

comment Using polygons with libspatialindex
Finding open-source libraries which spatially index in 16 dimensions is going to be a challenge. Unless you mean "vertices", not "dimensions".

comment Precision for an FGDB raster dataset?
The precision for pixel values depends on the pixel depth -- 1-bit, 4-bit, 8-bit signed, 8-bit unsigned,... Floating-point values are IEEE standard 4-byte (Float) or 8-byte (Double). Then you get to the compression algorithm -- lossy or lossless. If you chose a lossy compression algorithm, there isn't much room to complain about precision.

comment Precision for an FGDB raster dataset?
Your definition of precision is still unclear. Are you concerned with the position of the upper-left cell center? Grids use single precision, which is more than six significant digits (but may be less than six to the right of the decimal). Given it's a raster, I'd hardly think less than half the cell size would matter.

comment Problem opening shape file in qgis
I never said that recreating the .shx would fix dBase corruption, though I did say that the .shx has no relationship to the .dbf. A missing file does not automatically mean the dBase file has been corrupted, and even if all three files are present, they could have been corrupted by ASCII ftp transmission. .shx recovery should only be a last gasp effort before admitting the shapefile content has been lost.
