QGIS Lab06 Fall14: QGIS Vector Reprojection

Introduction:

This is sixth video tutorial of QGIS. It is about vector reprojection.

Summary:

  1. Reprojecting and Transforming Data
  2. Projections
  3. “On the Fly” Reprojection (OTF):
    1. What this means is that even if the data itself is in another CRS, QGIS can project it as if it were in a CRS of your choice.
    2. Also using NSIDC EASE-Grid Global  i.e., Projected Coordinate System (PCS) to keep scale constant.
  4. Saving a Dataset to Another CRS
  5. Calculating area using Field Calculator
  6. Creating Your Own Projection
  7. Data Required:
    1. exercise_data/world/world.qgs
    2. exercise_data/world/RSA.shp
    3. exercise_data/epsg4326/buildings.shp
    4. world/oceans.shp
