The two maps also identify areas where solution features that enable rapid movement of a pollutant may be present (identified as stippled areas) and areas where additional local information affecting vulnerability is held by the Environment Agency (identified as dashed areas). the vulnerability), the types of aquifer present and the potential impact (i.e. The map has five risk categories (High, Medium-High, Medium, Medium-Low and Low) based on the likelihood of a pollutant reaching the groundwater (i.e. This was developed for non-specialists who need to know the overall risk to groundwater but do not have extensive hydrogeological knowledge or the time to interpret the underlying data. The simplified groundwater vulnerability map.

These maps require that the user is able to understand the vulnerability assessment and interpret the individual components of the legend. This product is designed for technical specialists due to the complex nature of the legend which displays groundwater vulnerability (High, Medium, Low), the type of aquifer (bedrock and/or superficial) and aquifer designation status (Principal, Secondary, Unproductive). The combined groundwater vulnerability map.The 2017 publication has updated the groundwater vulnerability maps to reflect improvements in data mapping, modelling capability and understanding of the factors affecting vulnerability The Groundwater Vulnerability Maps show the vulnerability of groundwater to a pollutant discharged at ground level based on the hydrological, geological, hydrogeological and soil properties within a single square kilometre.

Notice the coordinates, they are no longer in lat lon, also chek the EPSG code of the project, now is set to 27700.This dataset is available for use for non-commercial purposes only on request as AfA248 dataset Groundwater Vulnerability Maps (2017). In order to check if everything is without problems I define a new project (poject/new) and load the reprojected shape file. When I am reprojecting I do not do this because Qgis will load the layer and will also activate 'on the fly reprojection' in order to show all the layers in the project even though they are in different coordinate systems. Also notice that I did not want to add the saved file to map. Notice that the CRS section has changed and now shows 'selected CRS (EPSG 27700, OSGB 1936/British National Grid)'. Once you hit OK you will have this dialog box: In my experience it is mandatory to select the coordinate system you want and check its parameters before selecting ok. In the image you can see the things I mention in the elipses. In the filter I write 27700, select OSGB 1936 British National Grid EPSG 27700 and I can see the parameters. I give a name and where I want to be stored in my computer.In the CRS section I choose the globe icon which let me select the coordinate system that I want.

In the format section I want a ESRI shape file. I selected my point layer (the waypoint), right click and choose save as. Also take in to account that the coordinate system of a GPX file is lat lon with WGS84 datum (EPSG 4326).

I did have a waypoint so I have only a point layer in my project. Waypoints are defined as a point layer, tracks and routes as line layers.

When you load a GPX file Qgis separates the way points, tracks and routes as different layers. I loaded the gpx file in QGis using GPStools (vector/GPS/Gpstools). Then I used gps babel to create a gpx file from the csv (you do not need to do this). I do not know exactly what are you doing, I did the following experiment.įirst, From the point you mention I created a csv file.
