comment Flagging when point feature(s) covered by tables (made as graphics) using ArcPy?
@user3697700 Excellent! Be sure to upvote the asker and answerer of gis.stackexchange.com/questions/21514/… if you found that code useful

comment How to show a selected polygon feature, using a single marker in its center
Check out gis.stackexchange.com/questions/71903/… - but I rue that POLYGONMARKERS did not survive the transition to Desktop.

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

comment Creating contiguous pixel based cartogram using ArcGIS for Desktop?
@ChrisW The point you make is valid - I'll forgo suggesting more changes on this one but I think the main gardening to be done on the original Question was to separate the Web GIS question from the ArcGIS for Desktop question. I think the Answer to the latter fits better here but far from perfectly.

comment How to create raster map by day that observed maximum NDVI from multiple raster data in R?
Would you be able to edit you Question to focus it on whichever is your preference to use, i.e. R or ArcGIS, please? If that does not get you your first choice Answer then you can always research/ask about the other separately.

comment “Levelling” elevation data coinciding with polygon?
To keep your Question as focussed as possible I recommend that you explore your preferred options of QGIS/GDAL/OGR first, then if you need to, research/ask about other software separately.

comment Efficient way to use a CSV to Define a Feature Class
Check out gis.stackexchange.com/questions/99792/… - adding 300-400 fields, assuming they are of allowed types, to an empty feature class should be much faster using arcpy.da.ExtendTable() than using arcpy.AddField_management().

comment Contouring surface with barriers?
Would you be able to edit your Question to include the precise steps that you used successfully without barriers, and then unsuccessfully with them, please? That will make it easier for any potential answerer to be sure that they doing exactly what you tried. Including a picture may also help.

This is an old Question, but if we are to try and Answer it, then we will need you to edit it so that it reflects where you are currently stuck. Try to make the new form of the Question as clear and concise as you can.

comment How to summarize GIS skills on a resume?
I made the ESRI/Esri spelling change because, although ESRI originally stood for Environmental Systems Research Institute in the US, and probably still does, it was re-branded from ESRI to Esri a few years ago - see esri.com/about-esri. To me the correct spelling and capitalization of company/product names can be an indicator as to how familiar a candidate is with Esri/ArcGIS literature, and in a world where everyone is looking for an edge ...

comment How to create surface by 3d building with different vertices
Welcome to GIS SE! Would you be able to edit your Question to include some additional details, please? For example, what version of ArcGIS for Desktop are you using? Do you have access to its 3D Analyst extension? What have you tried so far? Where are you stuck?

Can you edit your Question to include a copy or picture of the "strange characters that appear", please?

comment Writing values to feature class in Python script results in strange characters"?
Rather than create a trail of Comments, I think it would be better to try and address each that anyone makes with an edit to your Question that revises it to a more complete state.

comment Using ArcGIS Online Base Maps without Esri Software?
Would you be able to check/change the URL (spotless.com/au) you cite as the source for this, please? It seems to be an unlikely one and I would have suspected spam except that there have been no edits to your Question. Also, the quote does not seem to be related to the Question so perhaps you can add some additional text to explain how it does.

comment Using Scanaerial in JOSM?
Would you be able to edit your Question to provide more details about what you mean by "endlessly and never", please? How long have you left it to run before assuming that it will never complete?

BTW +1 Although here is not the place to share I think it is a good place to ask about where to share.
