comment How to determine area from polygon?
If you're using GIS software, you can just call the getArea() function on the polygon object. Some libraries hsve a getVolume request as well,

comment (python) distance between a point and a list of segments
You don't. Cartesian decimal degrees are useless. You can project the features to an appropriate projection and calculate distance there or use spherical or, better, spheroidal calculations to determine distance.

comment Using Python to select records by date field
It is important to understand that ArcGIS is NOT executing the query -- The database is. You must format the WHERE clause as it will be used by the database.

comment Using Python to select records by date field
"SQL" is a language, used by all databases. Do you mean "Microsoft SQL-Server"?

comment Using Python to select records by date field
"ArcSDE database" does not come close to describing the data source -- each RDBMS has a different timestamp format; we need to know which RDBMS is in use to help

comment Using Python to select records by date field
Date formatting is not at all standardized across databases. Please edit the question to specify the data source format on which this query would be executed.

You're missing a level of nesting -- fcList is a list so you need a for fc in fcList: with ListFields on fc

comment Spatial index in R - Performance enhancement on geospatial processing
Welcome to GIS SE. As a new user, please take the Tour. Questions here are expected to be focused on real-world problems, but this question is, well, vague. Do you have a specific issue with a specific dataset? If so, please edit the question.

comment Choosing server for dissemination and management of road data?
Instead of re-asking a closed question, please edit the original question to reflect changes requested in the closing messages. Polling for the "best" of anything isn't going to be successful here in GIS SE because the definition of "best" is too subjective. The only way to know why someone uses software is to ask them, and this is not a discussion and debate forum. The Don't Ask page has instructions on how to fashion a "good subjective" question, but not many such questions survive.
