Information

Earth observation

Earth observation is the gathering of information about Earth's physical, chemical, and biological systems via remote sensing technologies, primarily from satellites and aircraft. This practice, also known as remote sensing, involves acquiring data on the planet's land, oceans, atmosphere, and cryosphere. In Hebrew, Earth observation is referred to as צפייה בכדור הארץ (Tzfiya B'Kadur Ha'Aretz). Other relevant translations include Observación de la Tierra in Spanish, Observation de la Terre in French, and Erdbebachtung in German. Key applications of Earth observation include weather forecasting, climate monitoring, environmental management, natural disaster response, and agricultural planning. The data collected can be used to track changes in land use, deforestation, urban sprawl, and other environmental phenomena, providing critical insights for policymakers, scientists, and researchers. Major Earth observation programs include NASA's Landsat and MODIS missions, the European Space Agency's Sentinel satellites, and the joint NASA and NOAA missions like GOES and JPSS.

Help & Using the Gematria Calculator

This site lets you convert words, names, and phrases into numerical values using different gematria systems. You can use the main calculator gematria tool at the top of the page: type your text, choose a method, and press Convert.

1. Basic Steps

  1. Enter a word, name, or phrase in the input box.
  2. Select the desired system (Hebrew, English, simple, ordinal, etc.).
  3. Click the Convert button.
  4. Review the result and related matches shown below the calculator.

The calculator gematria tool supports multiple alphabets and standard letter–number mappings. More systems will be added in the future.

2. Reverse Gematria Calculator

The reverse gematria calculator uses the same alphabet as the standard system but assigns values in reverse order (for example, A = 26, B = 25, …, Z = 1 in a basic English reverse setup). This lets you compare standard and reverse values for the same text.

3. Working with Specific Values (Example: Earth observation)

Enter the word Earth observation and press enter or button Convert. This will provide all selected gematria values for Earth observation.

4. Calculator Compatibility

The site is designed to be compatible with common online tools and calculators, including the shematria gematria calculator and other popular gematria tools.
