[Qgis-user] QGis for bird surveys

[Lynkos]

I've just tried using the XY tools plug-in, but I get the message: "There
is a problem with loading a python module which is needed to read/write
Excel files. Please see documentation/help how to install python xlw and
xlrd libraries". I've tried following the instructions to install the
libraries, but to no avail. Once again, I come up against my lack of
experience and also lack of time to invest in learning. I think my best bet
for the moment is to adopt the simplest of approaches, using a text file
which given my limited amount of data should work fine.
Thanks again to you all and I hope one I'll be able to get down to learning
some of the basics which would undoubtedly be of great help.

>  1. Install "XY tools" using the Plug-in Manager (in menu - Plugins... Fetch Plug-ins... type xy in filter... XyTools 0.3.2... install);
> 2. After installation XY tools is found under the "Vector" menu item - make sure it is activated with a tick under "Plug-ins... Manage Plug-ins...";
> 3. Click "Vector... XY tools... Open Excel file as attribute table or point layer";
> 4. In dialogue box designate the columns in the spreadsheet that are the X and Y coordinates (Longitude or Easting = X; Latitude or Northing = Y) and click OK;
> 5. In the table of contents you will see a new layer called "Temporary Layer (volatile)"  SAVE THIS LAYER (see below - if you don't it will disappear when you close your project);
> 6. Right click the temporary layer name and click "Save As..." (remember to set your coordinate system - CRS - easiest if it is the same as "Project CRS");
>
> This will save your data as an ESRI format shapefile
>
> 7. Tick the "Add saved file to map box in the Save As... dialogue; and
> 8. Apply desired symbology to the new layer.

> worry about converting your data to a text file.  You can make separate
> files for each year's data or just keep concatenating new data onto your
> spreadsheet and creating an updated shapefile whenever you want to display
> the new data.  All of your attributes should be carried over into the newly
> created shapefile.  Make sure you have a header row with column headings in
> the first row of the spreadsheet and no blank rows in the body of the
> spreadsheet.

> Hope this helps.
