We've pushed a new minor update to the site, which includes some things that were postponed from the previous update. These are:
It also includes a couple of minor fixes elsewhere:
- Fixed a bug that caused Pit & Putt's map's home button to not recentre the map when you're in the middle of a game
- Removed the broken Welsh lidar layer from the Armchair Explorer
As always, do report any issues that you find in our
Issue Tracking thread.
Cheers,
Osian
Some details on the new utilities:
Coordinate Converter:
This is a full redesign, reimplementation, and expansion of the previous Gridref Converter tool. Here's a comparison of the two versions:
| Before | After |
|---|
 |  |
The new version supports even more coordinate formats, these being:
- Decimal Latitude and Longitude
- Degrees, Minutes, and Seconds
- OS Grid Reference
- OS Easting and Northing
- Irish Grid Reference
- UTM
These are selectable via the dropdowns. The source format dropdown will by default will have Auto-detect selected, which will use the first valid format it finds from your input.
Points that you enter through the text field will appear as markers on the map, where you can then drag them to move them, or click them to remove them. You can also add points directly by clicking on the map. Furthermore, if you hover over a marker on the map, a popup will appear showing that location in all of the supported coordinate formats:
The button in the top-right lets you export the conversions as a TSV table, which is directly pastable into spreadsheet software such as Excel.
Elevation Lookup:
This page lets you quickly query the elevation of any point in England, Wales, or Scotland (the precise valid area is shown on the map on the page). You can lookup up to 10,000 points at once (though beware that beyond 2,000 points your browser may slow down).
Similarly to the coordinate converter, you can use the map to add/move/delete points directly.
The colours of the map markers correspond to the elevations of the points. The colour scale itself, as indicated by the bar in the bottom-right of the map, depends on both the lowest and highest points you've added to the map.
The buttons in the top right are the same as for the coordinate converter, letting you copy the values as a TSV table, or download as a GPX file containing the elevation data for those points.
As an additional note, the tool uses a 50m heightmap to perform the lookups, using bilinear interpolation to smooth things out. As such, it can be less accurate on top of sharp mountain peaks, for example, but is quite accurate elsewhere.
