comment Using QGIS, how to save an attribute table as sqlite?
@Matte Both answers helped, but I still don't have a final solution. Removing "Add saved file to map" allowed the table to be saved as an SQLite - good! However, I am unable to add that SQLite table to QGIS. Here are the 3 methods tried so far: 1. Add Vector Layer: results in "Invalid data source..." 2. Add Spatialite Layer: results in "Unexpected error when working with: ...sqlite" 3. DB Manager: I can successfully connect to the .sqlite table, see its info in the info tab, and view its contents with the table tab! But r-click, "Add to canvas" results in "...invalid layer...". Thoughts?

comment QGIS 'Save As' to Spatialite is changing integers into strings
well, I updated to 2.14.1 (via the full OSGEO4W64 install), and I cannot recreate the problem, so I assume that the GDAL bug that you indicate must have been incorporated into this latest QGIS release. Sorry, but I don't have the programming skill to understand the links that you provide. Thanks for the help.

Ok, Spatialite is in and Geopackage is out!

comment How to delete fields from a Geopackage attribute table?
So, as I now understand, Geopackage is built on top of Spatialite, which in turn is built on top of Sqlite. Since Sqlite does not allow fields to be deleted or renamed (!!!), neither will Geopackage or Spatialite (although I was able to delete a field in Spatialite). Guess I'll be sadly sticking with shapefiles until this is resolved...

comment Spatial Join Hangs on Two Specific Shapefiles in QGIS 2.8
Alec, have you checked the shapefiles' geometry? I've experienced the kind of problems that you've described, only to have them solved by checking, then repairing geometry. Bad geometry is often unnoticeable until some particular action is attempted with the data. There is a topology checker plugin available.

comment Can I clip a geodatabase vector layer in QGIS?
What kind of polygon have you drawn? If it is just a graphic picture, then the Clip will not work, because it needs a polygon with the same real-world coordinates as the contour layer (as Freight_Train and Joseph have stated!). But if you create a GIS polygon layer (such as a shapefile) in the same coordinate system as the contour lines, then you could digitize ("draw") the polygon with the contours as a screen backdrop to help guide where the polygon boundaries should go. After saving the new polygon, it will be aligned in the same coordinate space as the contours, ready for clipping.

comment Is there an automatic function in QGIS to package all files in a project for transferability?
As of 2016-02-05 the QConsolidate plugin works correctly with shapefiles, tif rasters, and (!) Arc coverages. However, file geodatabase feature classes (as points) are not copied to the output folder.

comment Reclassify a raster based on proximity to other cells in the same raster
@FelixIP For the current project there will only be two values that need to be reclassified. However, I expect that there will be future projects where this type of reclass is required. My "and so on" was meant to reflect a sense of future utility.
