Image Classification Techniques in Remote Sensing [Infographic]
We look at the image classification techniques in remote sensing (supervised, unsupervised & object-based) to extract features of interest.
Equal Interval Classification in GIS
The equal interval classification method divides attribute values into equal size range taking the data’s minimum and maximum values.
Spectral Signature Cheatsheet in Remote Sensing
Every object has its own unique composition. This is equivalent to it having its own spectral signature. Choose the spectral bands for ideal classification
NAD27 – Meade’s Ranch at the Center of It All
Meade’s Ranch was the focal point of the NAD27 with all positions relative to it. First-order triangulation was used with approximately 26,000 survey points
Datum Transformations – Converting Coordinates from NAD27 to NAD83
NAD27 and NAD83 may differ in tens of meters for horizontal accuracy on location. Datum transformations correct your data from one datum to another.
