Would you be able to edit your question to include the GIS software and version that you are using, please?

comment Create layer from ArcGIS REST URL in ArcObjects using C#
Would you be able to edit your question to focus it on whichever of your two questions is more important to you, please? As per the Tour, you can always research/ask the other one separately.

comment Calculate geographic size in meters given lower left coordinate and upper right coordinate
The answer will also depend on what Projected Coordinate System you choose to project into. Would you be able to edit your question to specify that, please?

Would you be able to edit your question to revise it with any requested clarifications, please?

comment Adding an excel database to an existing shapefile
Would you be able to edit your question to revise it with any clarifications that we request via comments, please? That way the question is standalone rather than requiring potential answerers to read a trail of comments.

comment Adding an excel database to an existing shapefile
Would you be able to edit your question to include details of what you have tried so far and exactly where you are stuck, please? You seem to already realise that you need to use a Join.

comment Subquery in SearchCursor with ArcPy?
I suspect that this question amounts to a (near) duplicate of gis.stackexchange.com/questions/70488/… but in any event as @Hornbydd says the way to achieve this is by using the Summary Statistics tool.

comment Displaying coordinate references in GeoTools?
It looks like you are trying to ask three questions within this answer so I recommend taking the Tour for a very quick intro to how this site works.

comment postGIS: what is more efficient: single or two-point search
Please edit your question to include any clarifications to it requested via comments, and it is always easiest to know what is being asked if a question contains a single question mark.

comment How to create an SQL Persisted Computed Column which values are derived from spatial column
Please edit your question to revise it with the requested clarification and be sure to include a single question mark somewhere so that what you are asking is clear.

comment ArcPy Add Graph Window
Which version of ArcGIS for Desktop are you trying to use ArcPy from to do this? You have an arcgis-10.2 tag but reference ArcGIS Desktop 10.0 documentation. In any event I think you will find more ArcPy graphing options available at 10.1/2 than 10.0. Is your question perhaps a duplicate of gis.stackexchange.com/questions/100172/… ?

Please do not repeat the same question. I am sure that the volunteers here will be looking at your original posting at their earliest convenience.

comment Correlation between point feature (disease) and elevation
Welcome to GIS SE! Howeever, as it stands I think your question is too broad and that to make it OK for our focussed Q&A format we will need you to edit it with some details of what you have found in your initial research into looking for suitable techniques.

comment Replacing text string on layout text element by reading lookup value from table via SearchCursor?
Would you be able to edit your question to include a snippet of your code so far that works up to where you are stuck, please? I imagine that this would use a SearchCursor to load your table into a Python dictionary and then locate the text element object, and the string within it to replace by looking up the replacement value in the Python dictionary.

comment kriging interpolation of many z
At the moment you have posted a script with no indication of where it may be throwing an error, or starting to produce an unexpected result. I recommend that you try to replace it with a code snippet that works up to the point at which you are stuck.

comment Multiple Z point data kriging interpolation?
Please do not ask the same question repeatedly. The way to get it answered is by addressing the issues highlighted in your original question which you seem to now be doing. As soon as five people (or one moderator) think it is ready to be re-opened that will happen.

comment How to build a relational database system with 4 tables in arcgis desktop?
I think that you should try putting these tables into a file geodatabase and then to create relationship classes for each relationship you describe. If that does not "just work" then you should be in a position to ask a more focussed and answer-able question. I think your question needs to also so what data storage requirements you have i.e. is SQL Server in the picture (or not), file geodatabase OK (or not), etc
