comment Web Mapping Service Beginnings
Welcome to GIS SE! Please do not take offense that your first question has so quickly been made a duplicate of our most frequently asked question. I recommend you review that Q&A, decide which answer/technology looks like it may best meet your requirements and constraints, then give it a go. If you get stuck you will then be in a good position to ask a more focussed question about that.

comment Is there a bug with the “For” iterator in model builder?
I agree that the symptoms sound very similar to gis.stackexchange.com/questions/121653/… for which I have done no research subsequent to what is recorded in that Q&A. It's only a hunch but I suspect the source of this problem could be the same as whatever causes gis.stackexchange.com/a/36900 too.

comment How to change the dynamic information in data driven pages
For this I would use what I call pseudo dynamic text - definitely possible but non-trivial

comment Resample Landsat 8 to 60m Resolution
I'm confused - you say you are using ENVI and ERDAS, for which you have no tags, yet you have a tag for arcgis-desktop of which you make no mention in your question body. Can you use the edit button to clarify precisely what you are asking, please?

comment Export to KML (Portland) install fail on .dll load attempt
Would you be able to edit your question to include the version of ArcGIS for Desktop that you are using, please? With an error like this I would check that I am meeting the system requirements and then probably just uninstall/reinstall ArcGIS for Desktop as an expedient to avoid wasting time trying to debug an install that may have been corrupted in any number of ways.

comment How to combine multiple zipcode polygons into one polygon
Welcome to GIS SE! As a new user please be sure to take the Tour where something to note is that asking one question per question leads to clearer Q&As.

comment Use row as input to other processes in python
W.r.t. your previous comment selectingLayer is a layer object, and row.getValue() is expecting a field name so that code will inevitably error. If that code comes from exporting a model to a Python script then I think you would do better to start from a new script and just copy a line at a time into it, testing frequently, and making sure you understand what each does and why any errors you see occur.

comment Use row as input to other processes in python
Because you are new to Python I think you should take a step back from the question you are asking here, which I think I have answered, and instead aim for a better understanding of how cursors work first. Try writing some test code that adapts the first example at resources.arcgis.com/en/help/main/10.2/index.html#//… to your own data and when that makes sense come back and see whether my answer becomes more understandable.

comment How to cache and server pre-rendered vector tiles in pbf format?
I notice that your question body, title and tags make no mention of TileStache. If it is relevant to your question then I recommend that you review What makes a good question? and edit your question accordingly.

comment Offsetting Overlapping Routes in Network Analyst
The duplicates are a little messy on this but I agree with @ChrisW that yours appears to be a duplicate. If you decide to try and edit to separate your requirements from those of the current duplicate be sure to also review gis.stackexchange.com/questions/37777/…

comment Join and Field Calculator
Would you be able to edit your question to include a picture of the Field Calculator with your values - make sure that they are easily readable, and also a copy/paste of the text in your error message, please? If you can also tell us the version of ArcGIS for Desktop you are using that may be significant for this question. There is an edit button beneath your question to let you revise it with these details.

comment Equivalent of CORINE land cover data sets for rest of world
If the new question has not previously been asked here then asking it is appropriate. I would take care with its wording to make sure that it does not get confused with this one and made a duplicate of it as a result.

comment Equivalent of CORINE land cover data sets for rest of world
If an edit to the question has invalidated an answer that was provided in good faith based on the question then I think that edit should be rolled back and the Q&A resolved based on its state at that time.

comment What particular free softwares and what to do?
Your edit broke the link so I just rolled it back. You said that you have the data, which will be needed, but it sounds like you now want to use that for web mapping. That is a very large topic so your question has been made a duplicate of lots of resources that our users have been putting together for similar requests. I recommend that you review that and then edit your question to something that is more focussed so that it can be re-opened.

comment How to draw a polygon in openlayer 3?
Welcome to GIS SE! I think you are trying to use true curves in OpenLayers. I suspect @erilem may be looking for you to include the code you used to successfully do it as a linestring, and perhaps a more detailed picture.
