Geologic and Environmental GIS GEOS 5350 Spring 2011, T-Th (9:30-10:45am). Mohamed Sultan: Office Hours: Tuesday (4-5) Lab: Adam Milewski Office Hours: Thursday (4-5). Course Description.
Office Hours: Tuesday (4-5)
Lab: Adam Milewski
Office Hours: Thursday (4-5)
The course provides rigorous hands-on-exercises (based on data from case studies) on the applications of statistical methods, GIS technologies, and other computer-based software to the management, analysis, and display of multidimensional, geological, hydrogeological, and environmental data sets (70% of student effort). The course will cover (30% of student effort) the fundamentals of spatial data analysis and GIS technologies as well, since the students can not start dealing with applications unless they understand the fundamentals. In addition, students will be required to complete a research project using spatial data sets and acquired expertise
GIS Fundamentals & Applications - Mohamed Sultan (10 weeks)
This section will be mainly dedicated towards understanding and exploring the use of GIS technologies (mainly ArcGIS9.3 software) to address various geologic and environmental problems of concern including the following:
Coordinate systems and projections
Representation of Spatial Data
Spatial Data Input
Editing Spatial Data
Fundamentals and Applications of GPS
Generating and Interpreting Elevation Data
Watershed Delineation and Analysis
Spatial Data Models
Inverse Distance Weighted
Radial Basis Function
Future trends in GIS
3-D visualization (Geowall applications)
Kang-tsung Chang, Introduction to Geographic Information Systems
ESRI, ArcGIS Desktop
ESRI, ArcGIS Extensions
A written abstract/prospectus for the project before semester break. This will include the objective of your project, location, data, and analysis techniques, along with a description of the anticipated final product. We will also ask that you present an introduction to the project (before semester break if possible) in class in power point format. The final project presentation near the end of the semester will be in power point format and a report will be required.
A Computer System for capturing, storing, querying, analyzing, and displaying geographically referenced data (geospatial data, geographically referenced data)
The geodatabase view:
A GIS is a spatial database containing datasets with geographic attributes
ArcGIS Desktop—An integrated suite of professional
ArcGIS Engine—Embeddable developer components
for building custom GIS applications
Server GIS—ArcSDE®, ArcIMS®, and ArcGIS Server
ArcGIS is based on ArcObjects™, a common, modular library of shared GIS software components.
Central application in ArcGIS Desktop for
all map-based tasks including cartography, map analysis, and editing.
Helps users organize and manage geographic information (maps, models, metadata)
With ArcGIS 3D Analyst, users can:
– Contouring Data
– Raster Calculations (GRID functions)V – Spatial Analyst
level of spatial autocorrelation,
and variation among multiple datasets.VI - Geostatistical Analyst
Raster Data Representation uses grid (rows, columns) to represent variationsVector versus Raster
Expresses spatial relationships (e.g., two lines meeting at a point)
Simple and compact data storage
Difficult to find and fix errors
Method of choice when need a
More complicated and less compact data storage
Not as quickly
Can “clean up” maps easily.
Method of choice when need “smart map”
Attribute data describe characteristics of spatial featuresAttributes
A 2-D matrix with values for each cell
Data are divided into rows and columns
Location is a function of the structure (i.e. size of each cell).II - Raster
X,Y coordinates of at least one corner of the raster are known, so they can be located in geographic space
Grids can also be created by converting vector data
They can also store categories, such as for vegetation types
