OSNI Distance and Area Measurement Tool
A
distance and area measurement tool is available on this website. To access this
you must log in to the map store (by clicking the Map Store link at top of page). Click the 'Digital
Measurement' link and choose either 'distance' or 'area' from the panel below the address search.
Alternative
Distance Measurement Tool
If
the map console cannot accommodate the distance you would like to measure (due to loss of detail as
you zoom out) we have included an alternative distance measurement tool for your convenience. The instructions
on how to use this alternative method are below:
1. Access
map console by entering
'Map Store'
2. Click on Map Console icon
(bottom left of page)
3.
Do Address
Search for your school
4. Zoom to school
5.
Click on map
6.
Move
Arrow to centre of school
7. Record Easting
and Northing of school,
to be found on bottom
left corner of web page (round up to nearest 6 figure coordinate)
8.
Do address search
for
each house you want to calculate a straight line distance for
9.
Record Easting and Northing
10.
Open
spreadsheet ‘OSNI Distance Measurement tool’ (link is below).
11.
Enter your school name
and Easting and Northing (replacing Colby House and its Easting and Northing). The distances will all
change because of the coordinate change.
12. There are
a couple of sample addresses
which
you can overwrite if you wish
13. Enter
each address and its Easting
and Northing and
the
straight line distance will be calculated (there are already large distances up to row 30, as the formula
assumes that the Easting is 0 and the Northing is 0 and calculates the distance from your school to
the origin of the Irish Grid i.e. Easting=0 and Northing=0. As you input your new Eastings and Northings,
the formula will recalculate the correct distance)
