comment How can I Georeference a column of multiple zip codes?
Can you give an example of the contents of the 'comma separated string' you're trying to geocode in CartoDB? If you want a shapefile of zip codes for the USA, go here, census.gov/cgi-bin/geo/shapefiles2012/main, choose 'select layer type' and choose 'zip code tabulation areas' - the file is ~500mb but you can select and export (save as vector layer) the features you're after using QGIS then upload that result to CartoDB

@RyanDalton is -f for the filename rather than a column name in the destination file?

@MichaelMiles-Stimson DUDE where's my ArcGIS license? Glad you found the real problem. I used QGIS to look at the data.

comment How to check the resolution of converted raster file
I was under the impression that resolution of all rasters within a grass workspace were controlled at the workspace level, and that if you wanted to change the resolution, you would change it at the workspace level. Rasters with multiple resolutions were not possible... but I could be wrong!

comment How to union polygons and add attribute values of combined output features
Thanks @Paul Ramsey ... I think that's as good as things are going to get... We'll try this and report back.

comment How to union polygons and add attribute values of combined output features
@GISI I think the latter: "something more like map algebra, where intersecting areas are added together to form something like a statistical surface" Thank you!

comment How to determine the distribution of pollutants using marine tissue samples?--3D Interpolation
@alybab726 looks like because its on hold I can't submit an answer... but super glad you got what you were after! Maybe if you re-worded your question to ask about 'methods to do 3D marine interpolation' ??? or something similar it would be released?

comment How to determine the distribution of pollutants using marine tissue samples?--3D Interpolation
@albaba726 I only ask because you mention "how to interpolate this data across water depth", which to me means 3D interpolation... which I'm not sure how you do! You might want to look into some software designed for Marine Interpolation like Surfer goldensoftware.com/products/surfer

can you take a screenshot of your workbench, or if possible send me the path to the data you're working on and I'll try to get something going for you...

comment FME Workbench: Merging Multiple Shapefiles into One Database Table
Do the other workspaces use 'drop table first' or 'truncate table first'? If not you should be able to just keep writing data to the same 'writer'...

comment Can Viewshed produce area results per point feature?
What if you used Observer Points (OP), converted the output to vector in a file geodatabase (so you get area calculated - might have to project to local coordinate system), and summarized on the attributes that the OP tool created? Seems that would work just fine... OP creates a detailed attribute table that gives you all combinations of input points and the areas that are visible to them.

comment How to export tracks of a specific polygon in overpass-turbo?
you should just download the features via the bounding box and clip them using QGIS or the like. I don't think overpass can do the clipping that you're after.
