Course Summary

  • Pre-course reading

  • Setup open-source GIS program Saga

  • Area-of-interest maps

  • Data gridding

  • Managing GIS layers (size, placement, etc)

  • Motion vectors

  • Global relief data & products


1. Pre-Course Reading

Stimulating background materials, for better understanding of practical exercises


2. Practical Background for GIS

Hairy diagrams, made easy!


3.  Preparation for Course Exercises

Tight file/folder organization, structured filenames, and project segregation within the personal computer


4.  Basic Map Creation

Synthesis from many published sources: vectors, classified grids, polygons, etc.

Focus on Area of Interest (AOI)


5, continued

Ancillary objects: Frames, graticules, dummy grids, etc.


5, continued

GEBCO &other relief data: vector and gridded objects


5, continued

Many layers of named geopolitical zones and areas -- especially the VLIZ archives


6.  Gridding Data in Saga

Typical incorporation of station data into GIS layer, through points


6, continued

Experiments with various methods to obtain meaningful data grids

Methods to mask land areas


7.  Working with Grids in Saga

Grid images for publications, websites, Google, etc.


7, continued

“Classified” grids of terrain or habitat data

Special methods for satellite data


8.  Motion Vectors in Saga

Wind and current vector displays


9.  Special Options

Cutting and resampling to simplify collections


9, continued

Digitizing new shapes


9, continued

Setup for Pacific-centered projects


9, continued

Estimating relief contours from grids

Above and below the coastline


Postscript

  • This may be your first GIS experience. Expect these skills to become the backbone of your future career, because “everything is going GIS.”

  • You are strongly recommended to keep your PPT file, update or improve it whenever you can, and use it for demonstrations of your skills.
