Geotagging,It's Importance and It's Application.

Here explain about Geotagging, It's Importance and Uses of Geotagging.

What is Geotagging?

When you take a photo and activate your GPS, it saves the location where the photo was taken. Geotagging is the process of assigning coordinates to photos.

Generally, these coordinates are in longitude, latitude, and decimal degrees.

If you look at the properties of a digital photo, you can find these GPS locations in the EXIF metadata of your photos.

Geotagging Techniques

The basis for Geotagging is positions. In almost all cases, position is derived from the global positioning system and is based on a latitude/longitude coordinate system that represents each location on Earth in a coordinate that ranges from 180° west to 180° east along the equator and from 90° north to 90° south along the prime meridian.

Why is Geotagging Important?

Several facilities are being created in the states under various Department of Agriculture programmes.

Also under the RKVY programme, states have used significant funds to create infrastructure/facilities in agriculture and related sectors, such as soil testing laboratories, pesticide testing laboratories, and bio fertilizer production facilities.

Monitoring such widespread activities is of utmost importance for states and the GOI to understand the flow of funds, inventory the facilities, create transparency, plan the facilities for the future, and ultimately inform farmers about the available facilities.

Monitoring MGNREGA assets through Geotagging in his budget speech.

The Ministry of Rural Development has already started Geotagging MGNREGA and the Ministry of Land Resources for monitoring watershed assets in the states.

The Post Office has also Geotagged post offices using the NRSC-Bhuvan platform.

Geotagging standards in electronic file formats are :

1. JPEG photos

2. HTML pages

3. Geotagging in tag-based systems

4. Geoblogging

5. GeoTagging on Twitter

Applications and Uses of Geotagging

Because geotagged photos have locations, we often incorporate them into a web map so they can be used by a wider audience. Here are some examples of how geotagged photos can be used:

To track a trip or vacation, users take photos at various landmarks and locations. Then the traveler can put these geotagged photos on a web map to see where each photo was taken.

When exploring locations, photos are worth a thousand words. Not only can you check the location conditions from the photo, but you also have the photo coordinates for geolocation.

NASA is running an "Adopt a Pixel" campaign to collect ground-based photos to enhance land cover derived from satellite imagery. By geotagging each photo, you can better track locations because you know the GPS coordinates where the photos were taken.

Explanation of Geotagging

Geotagging services can be used to find location-specific websites, messages, and other information. They are based on positions and coordinates and are often taken directly from a global positioning system (GPS).

Some social networking sites and services reveal the location of their users, so that users know exactly where their friends are when they are logged into the site (or check in to the service).

When photos are tagged, it can be done with the camera after the shot is processed, or it can be applied when the photo is posted online. Most cell phones have a built-in GPS, so they can Geotag all photos taken with the phone's camera.

How can I disable Geotagging on an Android device?

To disable Geotagging on an Android device, launch the Camera app, tap Settings (gear icon) and uncheck Save Location. Or go to Settings > Apps > Camera > Permissions and turn off Location.

How do I turn off Geotagging on an iPhone?

To remove Geotags from iPhone pictures, go to Settings > Privacy > Location Services > Camera and tap Never. You can also select "Ask next time" or " When sharing" to allow Geotagging on a case-by-case basis.

Popular social networks that support Geotagging

When you post a status update or other media post on Facebook, you should see a small location icon that you can click to "check in" to a location. Use the dropdown menu to select a nearby location or search for a specific location. Your location will be displayed next to your Facebook post.

Geotag your Instagram photos and videos

Instagram is all about sharing on the go. Every time you get ready to post a new video or photo, you've the option to add a location in the caption tab. When you add a location, that photo or video will also be saved to that location on your personal Instagram map (in your Profile).

Geotagging your Snapchat photos and videos

When you use Snapchat, you can take a photo or video and then swipe right to add a fun sticker that changes based on your location.

Your device or computer will probably ask you for permission to access your location first, so you'll need to allow that before you can start Geotagging. Make sure you use Geotagging features safely and responsibly.

Geotag your tweets on Twitter

If your social profile's visibility is set to "public," remember that anyone can see a location you post. If you don't want to share your location publicly, either set your profile to private so that only approved followers can see it, or refrain from posting it altogether.
