Excellent overhead views but appears to give coordinates based on the WGS84(ETRS89) geoid which is not what the OS uses (OSGB36). Therefore consistently 100 metres inaccurate.

Seems to be pretty accurate although some users may be used to Eastings first.

Inaccurate?? Doesn't agree with OS by 100 metres.

I believe the output from this tool is in the WGS84 co-ordinate system. If you wish to compare this to an Ordnance Survey Map you will need to convert the output to the OSGB36 co-ordinate system. In short the output is accurate, but when comparing to other maps make sure you are using the same co-ordinate system.

Easy to use and seems accurate

Complete and utter waste of time, the Easting/Northing references are MILES out.

I think the calculations are not correct. I have compared the output from your map with 2 independent maps. Memory Map with OS-Maps from 2014 and UK maps with OS Maps (a free tool for iPad). The oucome is not huge, but at least a few 100 yards. However I think this is a brilliant tool and very good made. Just a slight calculation error in the NGR values ;-)

with reference to the map,is the movements voluntary of forced?substantiate your argument by mentioning three factors from the map and other factors to support the type of migration you mentioned.

No. Detail to maps. NGR are not accurate only approx

Accurate to 100m is fine for me! Great free tool if you don't need a pro level accuracy - and if you need pro accuracy, you should be prepared to pay.
