  KML vs. KMZ: Understanding the Difference KML ( Keyhole Markup Language ) and KMZ ( Keyhole Markup Zipped ) are file formats used in Google Earth, GIS (Geographic Information Systems), and GPS applications to store geographic data such as waypoints, routes, polygons, and images . 1. What is a KML File? KML (Keyhole Markup Language) is an XML-based format that stores geospatial data like points, lines, polygons, and annotations. It is human-readable and can be edited with a simple text editor. Used in Google Earth, Google Maps, ArcGIS , and other GIS software. A KML file can store: Placemarks (points with coordinates) Paths (lines for routes) Polygons (areas for marking locations) Overlays (images or maps placed over the Earth’s surface) 📌 Example of a simple KML file: <?xml version="1.0" encoding="UTF-8"?> <kml xmlns="http://www.opengis.net/kml/2.2"> <Placemark> <name>My Location</name> ...

What is latitude and longitude? Answer: Latitude and longitude are coordinate values used to determine a location on Earth's surface. 1. Latitude (Φ) Measures how far north or south a place is from the Equator (0° latitude) . Ranges from 0° at the Equator to +90° at the North Pole and -90° at the South Pole . Lines of latitude are horizontal and parallel to the Equator. 2. Longitude (λ) Measures how far east or west a place is from the Prime Meridian (0° longitude) . Ranges from 0° at the Prime Meridian to +180° eastward and -180° westward . Lines of longitude are vertical and meet at the poles . Example: New York, USA → 40.7128° N, 74.0060° W Delhi, India → 28.7041° N, 77.1025° E What is UTM (Universal Transverse Mercator)? UTM (Universal Transverse Mercator) is a coordinate system that divides the world into 60 zones , each 6 degrees of longitude wide , and provides a uniform grid for mapping and navigation . Key Features of UTM: Divides the Ear...
