How to Calculate NDVI in ArcGIS in quickest way || Vegetation Indexing in ArcMap
Hi everyone,
In this tutorial i used landsat 5 to determine NDVI. If you use Landsat 8 then your need to simply change the band number and go with the process. According to this formula, the density of vegetation (NDVI) at a certain point of the image is equal to the difference in the intensities of reflected light in the red and infrared range divided by the sum of these intensities.
This index defines values ​​from -1.0 to 1.0, basically representing greens, where negative values ​​are mainly formed from clouds, water and snow, and values ​​close to zero are primarily formed from rocks and bare soil. Very small values ​​(0.1 or less) of the NDVI function correspond to empty areas of rocks...

Reclassifying Raster Image in ArcGIS || Replace Raster Value in ArcMap
Просмотров 2,9 тыс.3 года назад
Reclassification of continuous data involves replacing a range of values with a new values. For example, a raster depicting distance from roads can be reclassified into three distance zones. Reclassification is an important process when you need to combine dissimilar data using a common value scale.
How to Georeference an image or scanned Maps using Shapefile in ArcGIS || Georeferencing in ArcMap
Просмотров 1,7 тыс.3 года назад
Georeferencing is the process of taking a digital image, it could be an airphoto, a scanned geologic map, or a picture of a topographic map, and adding geographic information to the image so that GIS or mapping software can 'place' the image in its appropriate real world location. This process is completed by selecting pixels in the digital image and assigning them geographic coordinates. For m...
