In developing a digital topographic database for a GIS, topographical maps are the main source, and aerial photography and satellite imagery are extra sources for collecting data and identifying attributes which can be mapped in layers over a location facsimile of scale. The scale of a map and geographical rendering area representation type, or map projection, are very important aspects since the information content depends mainly on the scale set and resulting locatability of the map's representations. In order to digitize a map, the map has to be checked within theoretical dimensions, then scanned into a raster format, and resulting raster data has to be given a theoretical dimension by a rubber sheeting/warping technology process known as georeferencing.

The certificate in geographical information systems (GIS) provides professional training in the technology and application of computerized cartography and spatially referenced databases. GIS is an increasingly important technology in environmental sciences, urban and regional planning and management, marketing, criminal justice, communications, and energy and natural resource protection. course work provides knowledge of basic and advanced GIS techniques, developing procedures and databases for specific applications, as well as technologies and analyses supporting GIS. This 12-credit program is flexible in order to accommodate both students new to GIS and those who already have some experience with this technology.
This chapter introduces geographical information systems (GIS) by describing some fundamental concepts important to them in more detail. It aims to help the newcomer to GIS and to provide some understanding of what GIS are and what they can be used for. The concept of GIS will be described in a number of ways: formal definition, examination of distinguishing features in regard to other information systems, the type of questions it can help answer, its ability to carry out certain specific operations and, listing the components a GIS comprises. In addition, the subject matters of this chapter are both the latest developments in the fields of hardware and software in a GIS environment and future directions and trends in these fields. As the concept of GIS not only includes hardware and software, this chapter will, in addition, briefly consider types of data and data storage and the different types of user groups and their differentiated GIS needs.
This course provides an introduction to geographic information systems and methods of creating, maintaining, and displaying geospatial data and imagery using ArcGIS software. The course includes a broad survey of applications. Course topics include elements of GIS, analysis of spatial information, map creation and analysis, GIS data types, map projections and coordinate systems, and other related topics. Lecture 2 hours/Lab 2 hours/Total 4 hours per week. Lecture 3 hours per week.
Introduces the history, theory, and operation of Geographic Information Systems (GIS). Includes an introduction to GIS data sources, database design, data input, spatial analysis, and map production. Offers valuable preparation for careers in geology, geography, geographic information systems, geomatics, planning, surveying, marketing, environmental technology, biology, engineering, and other related fields. Lab access fee of $35 for computers applies. Software fee of $18 applies.
GEOG 3315 - Introduction to Geographic Information Systems3 Class Hours 0 Laboratory Hours 3 Credit Hours Prerequisite: GEOG 3305 or permission of the instructor. Students will be introduced to the basic design of state-of-the-art GIS and its analytical capabilities. Topics include: Geodatabases, applications in GIS, map projection information, raster/vector data models, introduction to available data on the internet, and basic GIS analytical functions such as querying and overlaying. The course will use ArcGIS to introduce these concepts in a hands-on environment.
Methods: To better map control programme activities to their geographical location, the malaria notification system was overhauled and a geographical information system implemented. The introduction of a simplified notification form used only for malaria and a carefully monitored notification system provided the good quality data necessary to support an effective geographical information system.
Results: The geographical information system displays data on malaria cases at a village or town level and has proved valuable in stratifying malaria risk within those magisterial districts at highest risk, Barberton and Nkomazi. The conspicuous west-to-east gradient, in which the risk rises sharply towards the Mozambican border (relative risk = 4.12, 95% confidence interval = 3.88-4.46 when the malaria risk within 5 km of the border was compared with the remaining areas in these two districts), allowed development of a targeted approach to control.
Discussion: The geographical information system for malaria was enormously valuable in enabling malaria risk at town and village level to be shown. Matching malaria control measures to specific strata of endemic malaria has provided the opportunity for more efficient malaria control in Mpumalanga province. 041b061a72
