I don't know why QGIS says "Download has been successful", but obviously
337 bytes is not enough.
Your bounding box is far too big to download for a request on the fly. You
should download your data using external services like
http://download.geofabrik.de/north-america.html

This tool in QGIS can download a neighborhood or a small town.

[Qgis-user] trouble getting data from OpenStreetMap

2016-04-28 Thread Stephen Sacks


Please excuse a naive question from a new QGIS user.
I have installed QGIS (version 2.14.1-Essen, code revision ea85bef) on 
my Dell desktop running Windows 7 Home Premium. I've failed on my very 
first task, namely to create a layer using data from OpenStreetMap.  
Very carefully following instructions in the User Guide, I did the 
following three steps:


1. Vector > OpenStreetMap > Download Data:
   I chose Manual and entered longitudes -77.0 and -70.0, and lat's 
44.0 and 41.0, which roughly encompasses New York and Massachusetts. 
After some back-and-forth of the progress bar, an .osm file of size 337 
bytes appeared on my hard drive and  I got a message saying "Download 
has been successful."


2. Vector > OpenStreetMap > ImportTopologyFromXML:
   I selected the .osm file just created and accepted the suggested 
file name for the .db output, and the connection name.  The box next to 
"Create Connection" remained checked. "Import has been successful" 
message appeared immediately, and a .db file of size nearly 6 MB showed 
up on my hard drive.


3. Vector > OpenStreetMap > ExportTopologyToSpatialLite:
   I did this step three times, once for points, once for polylines, 
and once for polygons.  In each case, the input DB file was the db file 
created in step 2 above.  In each case, under Exported tags I chose Load 
from DB, and in each case not a single tag appeared for me to choose 
from.  For each layer, I got an "Export has been successful" message. 
However, when the three layers (points, lines, polygons) appeared in the 
Layers Panel, all of them had zero feature count and all three attribute 
tables are totally empty.


  What am I doing wrong ?  Why don't I see the streets of New 
York and Massachusetts ?


 Thank you in advance for your help.  I'll be embarrassed if my 
error is blindingly obvious.


Steve
