Differences in Location Information from various Data Sources

This website gathers data from a number of different data sources for the locations of the METAR stations. Not suprisingly, there are a number of differences in the data, but what is suprising (to me at least) is the scale of the problem. This page does not attempt to analyze elevation errors. However, the links to the pjsg_*_location.txt files below do have the best estimate of elevation for each location. It is important to note that the positions and elevations in these files are taken from one or other source. There is no averaging of data.

The logic on this website imports data from the following sources:

The best estimate as to the locations of all sites above can be found in the fixed format file pjsg_all_location.txt, pjsg_all_location.xml and pjsg_all_location.csv.

The table above includes all the records imported from the various sources. However, data is only available for a subset of these stations (both METAR reports and Synoptic reports), and the table below is filtered by that criteria. This also reduces (dramatically) the number of stations in error.

The best estimate as to the locations of all the active sites above can be found in the fixed format file pjsg_active_location.txt, pjsg_active_location.xml and pjsg_active_location.csv.

You can also compare the data sources in a pairwise manner. This table is for > 3 miles. It is divided into two sections -- those sites with Data, and All sites. The format in both cases is HTML;
