Come trovare le coordinate di casa propria?
To find the coordinates of a location, follow these steps:
- Open the Google Maps application on your Android device.
- To place a red marker in an unlabeled area of the map, tap and hold the area.
- You can view the coordinates in the search box.
To find a location using coordinates, enter the coordinates in the search box of Google Maps. You can use a variety of accepted formats, such as:
- Decimal degrees (DD), e.g. 41°24’12.2"N 2°10’26.5"E.
- Degrees, minutes, and seconds (DMS), e.g. 41.40338, 2.17403.
- Decimal degrees and minutes (DMM).
Google Maps coordinates use the formulas of the Mercator spherical projection and are derived from the World Geodetic System 1984 (WGS84) data.
The coordinates are displayed in decimal format. For example, the geographic coordinates for the Colosseum are N 41° 53′ 24” E 12° 29′ 32”. Sometimes, to provide more precise directions, the DMS notation is used, but the seconds can be written in decimal format, e.g. N 41°53’24.8280 E 12°29’32.0136.
To read coordinates on Google Maps, follow these steps:
- Open the Google Maps app on your smartphone or tablet.
- Enter the coordinates in the search box at the top.
- Press the "Search" button on the on-screen keyboard.
WGS84 coordinates are expressed as angular quantities measured in degrees with decimal numbers. It is more advantageous to use WGS84 geographic coordinates (latitude and longitude) in decimal degrees format.
In UTM coordinates, the first number is known as the "easting". The orientation towards the east indicates the position towards the east. The numbers along the map’s edges correspond to UTM coordinates. The map has the Easting coordinates on the top and bottom sides.
Here’s what you need to know about Cartesian plane coordinates:
- The x-axis extends from left to right, and there is a second coordinate on the y-axis.
- The y-axis is vertical.
- Depending on the axis, positive numbers go up or to the right, while negative numbers go down or to the left.
Google Maps also provides coordinates directly in the "Decimal degrees" format, which is compatible with WGS84. To add WGS84 coordinates to Google Maps, follow these steps:
- Open Google Earth.
- Set the coordinate display to "Decimal degrees" (compatible with WGS84).
To find UTM WGS84 coordinates using Google Maps, follow these steps:
- Right-click on the desired point.
- Select "What’s here".
- The coordinates of the point will appear at the bottom. Click on the coordinates in the box, and a new window will open on the left summarizing the coordinates using both the DMS and WGS84 systems.
