Indian systems included
Kalianpur 1880, 1937 and 1975, the India zone grids, UTM zones 42N to 47N on both WGS 84 and Indian datums, and the WGS 84 state systems.
Plot Coordinates on a Map
Paste a column of coordinates and see them on a map at once. Join them into a line or close them into a plot boundary, then download in any format.
Comma, tab or space separated. Anything after the first two values becomes a label. Degrees, minutes and seconds work too.
Why this matters here
Older Indian survey and revenue records sit on the Everest spheroid, not WGS 84. Treating one as the other puts everything a few hundred metres out — enough to move a plot boundary onto a neighbour.
Bulk paste
Paste a column straight out of a spreadsheet. Anything after the first two values is carried through as a label, and the result downloads as CSV.
Nothing leaves your device
The arithmetic runs in your browser with proj4. No coordinate is transmitted, logged or stored anywhere.
Frequently asked questions
What formats can I paste?
Decimal degrees such as 17.298765, 74.345678, or degrees, minutes and seconds such as 17 17 55.5 N, 74 20 44.4 E. Comma, tab or space separated. Anything after the first two values becomes a label on the point.
Which order should the numbers be in?
There is a selector for it. Latitude first is the default, since that is how coordinates are usually written and read aloud. If your points land in the wrong place, that is the setting to change.
Can I make a boundary from the points?
Yes. Choose to join them into a line or close them into an area, and the area and perimeter are calculated for you. The points are used in the order you pasted them.
What if a line will not read?
It is skipped and counted, so you can see how many did not work. Lines starting with a hash are treated as comments and ignored deliberately.
