Use the clip tool, in the vector tool bar, or you can install this plugin : click =)

the cryptic error is being thrown because query.outFields expects an array query.outFields = ["*"];

Are you sure the Shapefile contains points? Shape_Leng is a common attribute for lines. That could be the reason why you can't export X and Y coordinates from your Shapefile. In that case the new question would be how to extract points from those lines. For that, you could go to Processing->ToolBox->QGIS geoalgorithms->Vector geometry ...

You first need to establish what coordinate system the file sent to you is in. The presence of a .prj file indicates it does have one. If it isn't GCS WGS84, you'll need to reproject it to that (or an alternative geographic coordinate system [GCS] if another better suites your requirements). In QGIS you can do this by right-clicking the layer and choosing ...

In case someone is interesting to accomplish this task, without needing it to be in ArcGIS for Desktop. In R, there is the automap package, function autoKrige. The new_data argument, which indicates where the interpolation will happen, accepts points (besides grid and polygons). The manual says: new_data: a sp object containing the prediction ...

One method would be to split your point file (via a select and export or some other method) into to new files - points within buffers and points that are not. From there you can use a Spatial Join (which doesn't require an Advanced License if you don't have one) to join the points outside the buffers to those inside. With the settings of that tool you can ...

Try using the Near (analysis) tool. The resulting table will show which point is closest by whatever OBJECTID you specify. Then perform a join and field calculate the values into your previous points.

When your visualization has a SQL query applied, which seems to be the case in this scenario, the table is set as "view mode", which means that you cannot edit the contents from that view. Editing contents stands for editing the values in the cells of your table, but also for adding new points as it's the case. In order to sort this out, you need to go to ...

I'm not sure if you can do it with pure styling, but by manipulating your tables some you can likely get your desired result. I would find a shapefile of NYC neighborhoods and upload that to Cartodb, then merge tables with a spatial join. Likely just doing count, to get the number of features, though you could also sum on a property. That will give you a ...

No workaround should be needed. What you did in the first place is the right way. Take this GML as input: <?xml version="1.0" encoding="utf-8" ?> <ogr:FeatureCollection xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://ogr.maptools.org/ mixed_points.xsd" xmlns:ogr="http://ogr.maptools.org/" ...
