Which method of finding the degree is the most accurate?
Google Earth gives the best accuracy. Use whichever method you understand well, the mobile app or Google Earth, and practise drawing the yellow ruler line: if it shows 28 degrees, North lies at 0 behind it and the chakra is turned 28 degrees to the left.

A client's location shows coordinates. What do I do with them?
Copy them and paste them into the Google Earth search bar, which takes you to the place. Then draw a straight line along a wall of the building to get the degree. A degree taken from the centre is wrong; the centre only tells you which direction a room is in.
How do we know that a tilted-looking map has been drawn to zero degrees North?
Open the location in Google Earth with North set at the top and compare. If the plan looks identical, it is drawn at zero degrees and is zoned without rotating the chakra; about 90 percent of such tilted maps are drawn that way. If in doubt, rotate the map until one straight side is straight and take the tilt from that side.
Is there a rule to draw the Google Earth line from left to right or from right to left?
There is no rule. Drawn the opposite way, the same line reads 180 degrees more, for example 208.9 instead of 28.9; subtracting 180 gives the same answer, so a line can never give a wrong result just because of the direction in which it was drawn.
Should the client send a live location for taking the degree?
No, ask for the current location; a live location cannot be opened for this work. Copy the coordinates, paste them in the Google Earth search box and confirm with the client that it is the right property before taking the degree.
What is the most important step in marking a Vastu map?
Taking the degree correctly from Google Earth and marking north correctly. If north is right, everything else falls into place; if it is wrong, every zone, devta and ati marma goes wrong. Almost every plot, house or factory is tilted, usually by about 10 to 20 degrees, so north must be measured with care.
What should students get for learning to find directions and degrees?
Buy a liquid-filled compass from a stationery shop or online; it makes it easy to set zero degree and read degrees. Also download Google Earth on a laptop or computer and install a compass app on the mobile, which works only on Android phones, not on iPhones. Geo Vastu does not sell a compass of its own.
