I am attempting to create a simple distribution map.

I have created a vector layer by importing a table in .tsv file format consisting of a list of named points with latitude & longitude in decimal degrees plus heights. CRS is EPSG:27700 (OSGB 1936 British National Grid), the same as the other layers in the project. I can see the points displayed in the correct positions relative to one another by highlighting and zooming to the layer, but I cannot see any of the other layers. The attributes table has data in it which corresponds to the ’tsv spreadsheet from which it was derived.

I have also saved the file as a .shp file; again, I can zoom to that layer and see the points, and the attribute table looks OK, but I still can’t see any of the other layers, except for the .tsv layer from which the new .shp file was derived. To return to the other layers I have to select one of them and click the zoom to layer tool. But then I can’t see the new layer.

I’ve had several attempts at importing, including importing using CRS ESPG:3857 (WGS 84 / Pseudo Mercator). Result is the same. I have CRS transformation ’on the fly’ enabled in Project Properties.

I would be grateful for advice as to how to solve this problem.

I am using QGIS 2.12.1 on a Mac (OS X 10.11.3 El Capitan)

  • This suggests a CRS problem. You can check if it is a visibility problem by writing down the cursor coordinates when you zoom at the points layer and when you zoom at the rest. However, i think that either all the others layers or the one that shows up elsewhere have their original crs defined incorrectly. – vagvaf Jul 31 '16 at 17:27

    Your points can not be in decimal degrees and epsg:27700 – Ian Turton♦ Jul 31 '16 at 18:48
  • Thanks for your replies. Co-ordinates for the vector layer I created appear as latitude & longitude; those for the other layers are Ordnance Survey Grid. As all these layers are data from government agencies and the like, these must be 'correct' and the layers in decimal degrees are 'incorrect'. So, how can I turn the decimal degrees into OS Grid references - can I do this in QGIS, or do I need to find a means of translating from one system to the other before importing the data (& if the latter, what can I use?). Your help is much appreciated. – Jonathan P Aug 1 '16 at 19:39

Try using the Reproject layer tool from the Toolbox (enabled from Processing--> Toolbox): qgis_toolbox_example_reproject_layer

I was able to reproject a .shp file from UTM 31N to WGS 84 without any problem using it.
