comment Displaying a shapefile stored in postgis database in a google api using php
I'll give you a hint to get started: Shapefiles are not stored in databases with geometry types -- The shapefile data is converted into a table, which is queried using SQL. If you approach the problem as if this data is still a shapefile, you are unlikely to query it correctly.

comment Generic term for CRS axes?
"X" and "Y" are valid if you present them in the correct order (Latitude is Y).

You've hit a closure trifecta: Too broad, primarily opinion-based, and unclear. Please try to edit this question to make it answerable.

comment Performing a 'far analysis' using ArcGIS for Desktop?
Indexing, by its very nature, is optimized to find "close" things. It's unlikely you'll ever find an efficient way to find "far" ones. There is no shortcut to the furthest possible point.

comment Divide a large polygon into 4 smaller ones having same area
There are an infinite number of ways to accomplish this, but the problem itself is very difficult to solve for irregular shapes (computationally expensive). That said, this question already has an answer gis.stackexchange.com/questions/3130/…

comment Batch merging shapefiles from different folders, different subfolders
What software are you using? What version? (Please update the question). Technically, shapefile names which are not "8.3" formatted are non-compliant. Putting spaces in a shapefile name is a big no-no.

comment Aligning data in GCS_North_American_1983 and GCS_North_American_1927 using ArcGIS for Desktop?
In what format is the data (shp, FGDB,...)? Does the data align when projected on the fly? Have you tried redefining the coordinate system? If so, does it align then? Please update the question.

comment Aligning data in GCS_North_American_1983 and GCS_North_American_1927 using ArcGIS for Desktop?
That's only valid if the data is in NAD27. It could be that the vendor is clueless about coordinate systems.

comment Getting coordinates perpendicular to AB
There's also some perceptional dissonance in having point C at {4,4}, but not due south of A at (visually) {4,8}, or due west of B at {8,4} (ditto). If the coordinates are {Y,X} because you're plotting {lat,lon}, then there are issues with construction of a perpendicular line in angular units, which will significantly impact distances over 300 nautical miles.

comment Getting coordinates perpendicular to AB
I moved the question out of the code block, but the Question itself still needs editing for coherence. Your first diagram is missing points for A and B, and the periods after A, B, and C are confusing. The final image does not improve the question, and frankly, just hides the question. It's also not clear how this isn't a simple computational trigonometry question more appropriate to a math or computer science context.

'tweren't me, but I can't help but notice you didn't actually ask a question.

comment How to …NonRelational geoDB to Relational geoDB
It's probably important to understand that a Workstation ArcSDE geodatabase isn't a personal geodatabase or really even ArcSDE.

comment How to …NonRelational geoDB to Relational geoDB
Maybe you should work on normalizing your data in Access before you convert to SQL-Server Express. You should edit the question to specify versions of software.

comment Create Blank ShapeFile in C#
Welcome to GSE. Please update the question to include enough detail to make it answerable. You should include more details about your development environment (OS, compiler, code library version) and details of what you have tried so far. You should probably define "blank shapefile", since no such thing exists. If you don’t demonstrate effort in the question, it's unlikely that you will receive an answer.

comment How to check out arcgis 10.2 desktop license using arcpy?
The documentation you cite states that it is required to import arcinfo before import arcpy to checkout that product (which is not an extension).

comment Opening image in ERDAS Imagine
Please update the question with these details. You should find a data integrity tool like the two sum tools mentioned above. I expect one of the two files is different that the files on the working hosts.

comment Opening image in ERDAS Imagine
Also, the location. Is it the same file that others are reading, as from a network share, or does each workstation have a unique copy? Have you tried generating an md5sum or shasum from multiple hosts?

comment Opening image in ERDAS Imagine
Can any other application read the file? It's far more likely that the file is corrupt than anything is wrong with Imagine.
