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;
The HTML files above contain a number of columns:
| Distance | The distance in miles to the chosen point |
| Name | The station name (ICAO code) |
| Latitude | The chosen station Latitude (in decimal degrees). This is what this website has determined is the best guess as to the location. |
| Longitude | The chosen station Longitude (in decimal degrees). This is what this website has determined is the best guess as to the location. |
| Elevation | The chosen station Elevation (in meters). This is what this website has determined is the best guess as to the location. |
| AltLatitude | The station Latitude from the comparison source. |
| AltLongitude | The station Longitude from the comparison source. |
| AltElevation | The station Elevation from the comparison source. |
| Source | The URL (or other) of the chosen source for the location data. |
The TXT and CSV files that contain the complete database have the following columns:
