Coordinates 4.5 : World Magnetic Model Calculator


It’s been a week with a lot of updates

Coordinates 4.5 adds three more features! (I would call this version 5.0 if I could polish its design a bit more).

  1. World Magnetic Model Calculator!


It’s now possible to calculate these information related to geomagnetic fields

D = Declination (Degree)

I = Inclination (Degree)

X = North Intensity (nT)

Y = East Intensity (nT)

H = Horizontal Intensity (nT)

Z = Vertical Intensity (nT)

F = Total Intensity (nT)

GV = Magnetic Grid Variation (Degree)

Press Magnet icon on the main page to view these information

Press on Altitude or Date to make changes to these value

Select WMM model to use in setting menu (WMM2015 or WMM2015v2)

2. View more coordinates at once


Press Number 2 icon on the main view to turn on secondary coordinates banner.

Select coordinates type as you wish.

3. View transformed coordinates on map


In transform coordinates menu, all coordinates type will be available to view on map.

However, it’s not possible to save pin as this time.

4. Performance Boost

We removed redundancy calculations from the app. It should works faster on slower devices.

Instruction will be updated soon.

Some good news

Hello everyone, I’m delighted to talk about new updates to our apps today.



We added whole new section to this app: Coordinates convertor.

Now you can convert lat & long coordinates, geodetic datums and projected systems. Search online database for any system / datum.

Press EPSG button to access this page

Sorry for bad UI. We will update this soon once we received more feedback

If search result is not available. Note that you can put your own custom system. Make sure it’s in proj4 format. for example:

+proj=lcc +lat_1=42.6833319 +lat_2=41.71666666666667 +lat_0=41 +lon_0=-71.5 +x_0=200000 +y_0=750000 +ellps=GRS80 +units=m +no_defs

put this line in code textbox and it will works just fine.


now we have new name for this app

Area & Distance - Map Measure

Yes. It’s now possible to measure distance within this app. We decided to merge DistancePinner into this one app.

Area and Distance in one app

Area and Distance in one app


The best thing with this update is that you no longer need to place center pin before start measuring! Any complex shape will works now as long as there’s no overlapping line!



The app is back up and running as normal. However, we need to add timer between each data access or we can’t provide the best app experience to everyone.



We added bunch of new localization. We still need more downloads to match our past BlastSim app.

We admit we releases new version very often during the past week. Sorry for inconvenience . In the meantime we will update documentation on this website to reflect new feature of our apps.

Again, feel free to contact us for any suggestion, or just talk to us! and we are sorry that we are unable to answer them all during last year.

That’s all about it. See you again next time!

Ps. Anyway, I’m still curious that is anyone is reading this blog. If you want to show that you came pass this, please write “ Katamari “ on the subject section and send me a message lol.
Not required. Just for fun :)
