Maybe James Crandall can have a look. I know he uses Panda a lot.

Yes, you should be able to do this if you have a Spatial Analyst license available. More details in the Help topic on "Extract Values to Points (Spatial Analyst)"

I wouldn't join those 47 million points with your 1700 features. For these types of analysis it is custom to convert your elevation points to a Digital Elevation Model (DEM). Use Spatial Analyst of 3D Analyst for this purpose. Depending the type of geometry of your features you can do various things: For polygons perform a zonal statistics (as table), using your polygons as zones and the DEM as value raster. This will yield statistics (min, max, mean, etc) for each polygon (Spatial Analyst required) In case of points you can use the Extract Values to Points tool that will retrieve a single elevation for each point (Spatial Analyst required) For lines I would probably convert them to raster using a unique identifier and do the Zonal Statistics (Spatial Analyst required). In case you don't have 3D Analyst and/or Spatial Analyst, select relevant features by a select by location, using a small buffer. Export that selection to a separate layer and perform the join... Kind regards, Xander

Have a look at the description you'll find in the Help topic: Applying filters Scroll down to "Considerations for creating and working with filters". It seems that instead of "All" you can use "Any".

There are a lot of discussions and polls about the question if this is better than the previous forums. It will take you more time to get used to, but once you get familiar you'll learn the new extra possibilities too. A great place to start learning about how to use GeoNet is:GeoNet Help Kind regards, Xander

Also in version 10.1 the symbols are displayed without the white square: Be aware that all layer beneath the points will be rasterized. For more information on that, please read the help topic on "About map printing", especially the part on "Printed map appears blocky or pixelated - Rasterization" in Troubleshooting map printing. You can also define an equal color for the background and select that color as transparent color (not possible for PNG, but you can do this for GIF, BMP, etc). This might be a little rough with the symbols you're using since they have a semi-transparent shade surrounding the picture.

Apparently the wildcard is working, assuming that the rasters of interest start with "nofpt" are TIF fiels and reside in the workspace indicated. Some remarks: There is no need for spatial analyst to convert raster to polygons With your code the output shapefile will have the name "nofpt_somename.tif.shp". Not sure if you want that... Have a look at the code below. This will remove the .tif extension from the output shapefile name (see line 9).
import arcpy
arcpy.env.overwriteOutput = True
#set the workspace
arcpy.env.workspace = r"C:\Users\Windows\Documents\JO_GIS_Analyst"
#Get a list of rasters and convert to shapefile
for raster in arcpy.ListRasters("nofpt*", "TIF"):
shp_name = "{0}.shp".format(os.path.splitext(raster)[0])
print "Converting raster '{0}' to polygons '{1}'".format(raster, shp_name)
#convert the raster to polygon
arcpy.RasterToPolygon_conversion(raster, shp_name, "SIMPLIFY")
print "Finish converting the rasters to polygon"
For testing you could comment out line 13 and see what it prints. How many rasters are found? Kind regards, Xander

In python you can easily cut off the extension by using splitext. The point is that we are just guessing until the entire code is exposed...

Might have something to do with the creation of the pyramids. You could try to recreate them.

The error is caused executing a Join. You did not post the code referring this action. Please post as Curtis suggests.
