Does the number of decimal places in coordinates affect the speed of rendering of the features on a Leaflet map?

No, the number of relevant decimal places used in numbers do not matter. 

How many decimals do coordinates need?

So, when it comes to GPS data, you need coordinates out to at least five (5) decimal places to be useable in terms of locating and subsequently evaluating incremental speeds between points.

How many decimals are in a GPS coordinate?

Longitude and latitude coordinates are stored with 15 decimal digits right of the decimal points. By default LAStools will use 7 decimal digits to store longitude and latitude coordinates to a LAS or LAZ file.
 

Can you use decimals in coordinates?

Where necessary, the coordinates of a point can be specified by using decimals or fractions. However, locating points whose coordinates are not whole numbers requires more precision when reading along the axes. For example, here the coordinates of the point A are (2.2, 1.8).

How accurate are decimal places?

A value in decimal degrees to an accuracy of 4 decimal places is accurate to 11.1 meters (+/- 5.55 m) at the equator.



Accuracy.

Does more decimal places mean more accurate?

The number of decimal places correlates directly to the level of precision.

Why are decimal places important?

We use decimals every day while dealing with money, weight, length etc. Decimal numbers are used in situations where more precision is required than the whole numbers can provide. For example, when we calculate our weight on the weighing machine, we do not always find the weight equal to a whole number on the scale.
 

How do you graph coordinates with decimals?

Quote from video: So 1.4 in the x. Direction is positive so we're moving to the right and we're moving to the right 1.4. So that would fall between 1 and 2 and it's less than 1.5 so 1.4 will fall to about right here.

Why do we have 3 decimal places?

The third decimal digit from the decimal point is the thousandths digit. For example, 0.008 is eight thousandths. Read the whole set of three decimal digits as a number, and say “thousandths.” 0.825 has 8 tenths, 2 hundredths, and 5 thousandths.

What is the precision of decimal places?

Quote from video:

How far is 0.001 latitude?

0.06894 statute miles

1 degree of latitude in physical distance is 68.94 statute miles or 59.91 nautical miles (110.95 km) — for a spherical earth assumption. So, a change of 0.001 degrees latitude is 0.06894 statute miles or 0.05991 nautical miles.

How accurate are coordinates to 6 decimal places?

Therefore, it’s always safe to figure that the sixth decimal place in one decimal degree has 111,111/10^6 = about 1/9 meter = about 4 inches of precision. Accordingly, if your accuracy needs are, say, give or take 10 meters, than 1/9 meter is nothing: you lose essentially no accuracy by using six decimal places.

How many decimal places does NASA use?

15 digits

For most calculations, NASA uses 15 digits: 3.141592653589793.
