comment Determining direction of longest segment of polygon?
I think you would be better replacing your picture with one of just a single polygon that illustrates more clearly what "segment" you are calling the longest.

comment Chosing a GeoCMS server collaboration tool
Welcome to GIS SE! At the moment I think your question may be to broad for our focussed Q&A format but with some edits (you can use the button beneath it) you should be able to bring it on-topic. For example, if you were to list the GeoCMS software that you have already investigated and say why they do not meet your requirements, then that would save potential answerers from repeating your steps. Perhaps the focus (and title) of your question should be "Finding GeoCMS with in-built map server?"

comment Extremely slow processing time to map lat/lon data onto census shapefile with ArcPy?
You say that your problem occurs during the CopyFeatures step so I think you should edit your question to remove any steps subsequent to that. If you get past CopyFeatures in this Q&A then you can always research/ask about any subsequent problematic steps later. The other thing that I think you should edit in are the precise steps that you are performing in ArcMap so that we can see that your ArcPy script is accurately reproducing them.

comment Iterating using search cursor and layer selection performance?
I just updated my answer to demonstrate by way of a more rigorous performance test that using MakeFeatureLayer and CopyFeatures rather than Select is about 50% slower CC @StephenLead

comment How to create polygon feature class from UTM coordinates?
@T.WayneWhitley You are correct - I was copying from a screenshot in one of my training courses and missed that bit - has now been corrected

comment error while setting domain name in cartodb
While this link may answer the question, it is better to include the essential parts of the answer here and provide the link for reference. Link-only answers can become invalid if the linked page changes.

comment Querying Arcgis file geodatabase from sql
Would you be able to edit your question to indicate whether you have access to ArcGIS for Desktop, please? And if so, what version?

comment Iterating using search cursor and layer selection performance?
@Paul I'll await question clarification before posting more code but I am thinking that it is the CopyFeatures that takes most of the time, and if the only reason that is being done is so they can be added as layers to the map, then if all we do instead is "clone" 18 layer objects and set their DefinitionQuery property using the same where_clause then we will cut out perhaps 90% of the time taken.

comment How to lock points using a schematic layout algorithm?
We have not seen many Schematics questions here so I think it would help if you could include a picture to help describe what you are observing versus your requirement.

comment ArcGIS - Spatial ETL Tool - Checking fields in input shapefile
Would you be able to edit your question to include the version of ArcGIS for Desktop that you are using, please? Also, you talk about fields but do not tell us what format the tables they belong to are stored in.

comment convert csv file into grib2 format using wgrib2
GRIB2 seems to be a meteorological format so I think this question may be off-topic for GIS SE.

comment What projected coordinate system to use for whole of USA?
Egypt looks like it should be a separate question - please just ask one question here as per the Tour

comment Join of two attribute tables with different amounts of rows
I think you will find your issues much easier to explain if you keep them to just a few features/rows from any inputs.

comment Identity tool does not work as expected
I think the reason Identity produces the results you are observing will be very easy to explain if you include a picture of just Reg1 and anything that passes through it. Also, include the exact syntax used to run the tool which is easiest to grab by using Geoprocessing | Results to access Copy As Python Snippet.

comment Processing MOD35_L2 HDF Cloud Masks
Welcome to GIS SE! Although your answer may be correct, about a paragraph is considered minimum length for answers (and questions) so I recommend that you expand upon it with a brief detail or two. Also, there is no need to sign your posts here because every answer, question and comment is already signed by your user card.

comment How to export/save a layer composition to GeoTiff?
And if you are a developer or otherwise connected with this plugin be sure to disclose that in your answer too.

comment PostgreSQL Trigger on inherited tables
This question appears to be off-topic because it is about database administration and fits better on dba.stackexchange.com

comment where can i find latitude and longitude for the all state border of india?
Welcome to GIS SE! At the moment your question is not show what research you have applied prior to asking your question so I recommend that you edit it to do that and to provide more details of precisely what you are after, please? For example, are you looking for shapefiles or something else?

comment Migrating from GeoMedia to ArcGIS for Desktop?
As it stands I think your question is too broad because the Q&A format used here is about answering specific questions. I recommend that you edit your question to focus it on one specific task that you want to accomplish as part of your migration from one platform to another. The more you can show what steps you have started to take and then precisely where you are stuck, the likelier it is that you will get good answers.
