Prerequisites: Prerequisites: READING LEVEL 3 and WRITING LEVEL 2 and MATH LEVEL 2, and CST 133W or instructor permission.
Examines the fundamentals of geographic information systems. Requires the collection, manipulation and representation of data gathered in the field and from downloads. Introduces a wide variety of fields needed to gather or work with GIS based technology. (45-0)
Outcomes and Objectives
Identify basic components and applications of Geographic Information Systems (GIS).
- Demonstrate an understanding of the many applications of GIS.
- Identify the components and purposes of a suite of GIS software applications and collect data pertaining to geographic areas and land forms and organize the collected data into sets.
- Demonstrate the ability to appropriately manage data and problem solve to address problems and questions typically addressed with GIS systems.
- Use data analysis to inform decisions. Data analysis will include data on natural resource planning, but will not be limited to that field.
Use the conventional expressions and representations of location in GIS.
- Describe different datums, latitude, longitude and coordinate systems
- Apply the concepts of projections and scale
- Describe how locations on a sphere are translated into a plane
- Convert from one datum to another.
Use various forms of digital data while effectively using a GPS hand-held unit.
- Download available maps, datasets and tables from the internet.
- Identify data limitations and data quality issues, such as map and data accuracy.
Download data into ArcGIS and contribute data to this same database.
- Use points, lines, polygons and vector data in a variety of formats such as in software as well as in a printed map.
- Use raster data to create a description of the physical characteristics of a geographic area that are organized as a map.
- Combine different data sets on a displayed map.
- Apply collected data to an existing map.
- Select, query, and manipulate data utilizing proximity, buffer, union and merging.
- Evaluate geometric features such as - length, distance, area.
- Use tables and fields to accomplish tasks such as joining, relating and address matching
Interpret and express data in GIS software
- Use several software components to integrate existing data sets.
- Answer an environmental question using data from a defined land area.
Collect and apply their own data in ArcGIS.
- Collect data in the field, at such places as the Shiawassee National Wildlife Refuge, using GPS map units.
- Identify and collect data using an accepted method such as the forest assessment protocol.
- Apply the data to a map in GIS.
- Use multiple techniques to manipulate the data in order to solve a problem or answer a question.
- Produce a report including a written report and a visual map.
- Complete an in-class presentation about their data.
