Dec 4	answered	data type conversion extracting user defined tags as columns using Openstreetmap data
Dec 4	comment	What is the SRS code for Lambert Conformal Conic projection and GCS Everest Definition 1962? Thats only the datum. You have to add the parameters for lcc projection to get it working.

Dec 4	comment	How to georeference using Latitude and longitude in QGIS? For vector layers: Save As... and select another CRS and filename, and add that file to the canvas.
Dec 4	comment	How to georeference using Latitude and longitude in QGIS? That won't work, maybe only for the measuring tool. Field caculator only looks at the coordinate data stored for the layer. After reprojecting (and saving to another file), field caculator has the values to do the calculation right.
Dec 4	comment	QGIS: On the fly projection from WGS84, 19 N, to Web Mercator. Do I need to define a new CRS with transformation parameters? NAD27 is a bit difficult: The towgs84 parameters vary for every point of the earth. Qgis uses a official US grid file for that, but that is only exact for the United States. And Dominican Republic is not covered by that. So it would be best to re-georeference your topo map by identifying remarkable points in the map and in Google Earth, saving the map in WGS:3857 (as GE uses), and then maybe reprojecting it to WGS84 UTM 19N to have real metres as map units.
Dec 4	comment	How to georeference using Latitude and longitude in QGIS? The field calculator always uses map units. If you want meters, you have to reproject your data to a projected CRS in meters, like UTM.

Dec 3	answered	How to draw a closed line in QGIS1.8?
Dec 3	answered	Georeference information stored in tfwx (from ArcGIS). Is it possible to see the georeference in QGIS?
Dec 3	comment	Why does a track point layer attribute table have no positional information? You have to export the track_points layer to another format, like shapefile. That format can be edited. Loading GPX with Add Vector layer is just import, unless you use Vector->GPS-> GPS tools. But that won't give you track points.
