Projected Coordinate Systems

The Projected Coordinate System helps you to project a specific round-earth model onto a flat surface or map. PCS are created by projecting the 3D GCS onto a 2D surface. The projected coordinate system tells the data on how to draw on a flat surface. There are many different map projection...

Vector Data in GIS

The spatial characteristics of features can be stored in GIS in one of 2 ways: Vector data or Raster data.

Raster data is made up of pixels (also referred to as grid cells). Each pixel is associated with a specific geographical location. The value of a pixel can be continuous (e.g., Slope) or d...
