Geographic Information Systems Practicum

GIS consists of software and data used for geographical analysis and map making. It can be applied to any discipline.

Introduction to GIS using Open Source Software is a day-long workshop offered each semseter. Current graduate students, faculty and staff from throughout CUNY can register.

Visit the GIS practicum page for eligibility, registration, and course details. Access the practicum manual and the additional raster tutorial.

 

What is GIS?

GIS is an integrated collection of software and data that visually organizes information around the concepts of geographic location and space. GIS can be used for geographic analysis, map making, database management, and geospatial statistics. GIS can be applied to many applications in several fields of study. You can use GIS to:

  • Study the distribution of populations
  • Study physcial features of the earth and natrual phenomena
  • Find the optimal location for starting a business or locating an event
  • Identify markets to target
  • Identify geographic patterns like clustering
  • Determine the best routes or paths to follow
  • Tie together separate pieces of data to create new information
  • Create maps

 

Visit the USGS GIS Poster and the Encyclopedia of Geographic Information Science (CUNY affiliates only) to learn more.

 

Basic GIS Principles

  • Geographic features are stored in individual GIS files. These files are the raw materials for geographic analysis and map making
  • GIS files are georeferenced, which means features are drawn to scale and tied to actual places on the earth via coordinate systems and map projections
  • Since coordinate systems and map projections are standardized, GIS data from many sources can be shared
  • GIS files come in several different formats; they can represent continuous surfaces (raster) or discrete geometry (vector)
  • GIS software is the tool / window for viewing, analyzing, and manipulating GIS data
  • Data tables that are place-based can be converted into GIS data by either plotting the table data using latitude and longitude or by joining table data to GIS features using a common ID code
