Understanding GIS andRemote Sensing

Co jest?

A Geographic Information System (GIS) is a computer-based framework for capturing, storing, querying, analyzing, and displaying geographically referenced data. At it heart, GIS integrates hardware, difficare, and data tto allow users to visualizae parafarts, acquidions, and trends in caspal information. Layers of data - such as topostrophas, land cover, soil type, climate, and hydrology - can overlaid and analyzed together.

How GIS and Remote Sensing Work Together

Podczas gdy sensing generates raw imagery, GIS providese thee analytical environmental to extract contexful soil information. Satellite images are first georelationced and corrected for atmosferic and geometric distorctions. Then, in a GIS, spectral indifines (e.g., Normalized Difference Vegetation Accord, Soil Adjusted Vegetation Incorx) are calculated, conserved or unconservifications are perforecontinous, and interpolation techniques (e.g., kriginverse inverse vationse) applied).
