Aims Objectives
  • Develop an understanding of the unique
    characteristics of environmental data
  • Acquire skills in spatial analysis techniques
  • Gain background and hands-on experience with
    software tools for working with data and
    conducting spatial data analysis.
  • Examine the art of visualizing spatial data and
    data analysis results
  • Appreciate the complexities involved in data
    manipulation, analysis, and mapping

My aim and objective is for each of you to become
a SAP!

Journal Article Review
For this paper assignment you will select and
review a journal article that describes a spatial
analysis method from a topic area covered in
class. The paper should be a 2-3 page summary
for ENVE 424 and approximately 4-5 page critical
review for ENVE 524. Please notify me of your
article selection by Tuesday, March 29. Paper
reviews are due Thursday, April 7.
Example Journals
International Journal of Geographical Information
Science Environmetrics Computers and
Geosciences Photogrammetric Engineering and
Remote Sensing Journals in your field

Final Project
  • The project involves data analysis for a problem
    of interest to you. You will analyze your data
    using several of the techniques discussed in
    lectures and the GIS tools introduced in lab. A
    project consists of three components
  • Proposal describing the problem and the data and
    methods to be used (up to two pages) Due March
    24
  • Paper describing the project data, methods,
    tools, and results. (up to 12 pages)
  • Presentation summarizing the project. (up to 10
    minutes)
  • Paper and Presentation are both due on the date
    and time assigned for our final exam period.
  • Two (of many) options for projects
  • Compare different methods
  • Analyze your own data

What is Spatial Data Analysis?
  • Spatial analysis is the quantitative and
    qualitative study of phenomena that are located
    in space.
  • Environmental spatial data analysis describes
    characteristics and behavior of the environment
  • Explores patterns, trends, and relationships in
    environmental data
  • Seeks to explain these patterns, trends, and
    relationships
  • Differs from general data analysis in that it
  • Spatial data are dependent on location and
    related by location (they do not adhere to the
    independence assumption made in regular data
    analysis)
  • Have properties that require special analysis
    methods

27
What is GIS?
Traditional definition is that GIS is a set of
computer tools for accessing, processing,
visualizing, analyzing, interpreting, and
presenting spatial data. GIS is Geographical
Information System OR IS IT Geographical
Information Science? GISystems Emphasis on
technology and tools GIScience Fundamental
issues raised by the use of GIS, such
as Spatial analysis Map projections Accuracy
Scientific visualization Implementation and
application of GIS covers a wide spectrum Simple
maps Overlaying multiple map layers Conducting
proximity or cluster analysis based on
distance Comparing data sets (simple spatial
statistics) Complex statistical analysis
28
Whats the Difference?
The distinction between spatial data analysis and
GIS becomes fuzzier every year The distinction
depends on your perspective Traditional GIS
perspective Here are some tools, use them.
Import data into a GIS and what you see is what
you get. Traditional spatial analysis
perspective Start with spatial analysis and
use GIS as a tool. Use GIS to help figure out
what the data means
In many fields, the two perspectives appear to be
merging as one Spatial analysis is GIS GIS is
spatial analysis
29
Geospatial Information Science and Technology
acquires, manages, interprets, integrates,
displays, analyzes, or otherwise uses data
focusing on the geographic, temporal and spatial
context. (GeoSpatial Workforce Development
Center at the University of Southern Mississippi)
  • According to a recent Department of Labor report,
    the three most important emerging and evolving
    fields are
  • Biotechnology
  • Nanotechnology
  • Geospatial technology
