Course content

5 sections • 28 lectures • 28m total length

Self Introduction1:50
Introduce geographic information systems concepts through the instructor's experiences and background, highlighting practical insights from over 10 years of engineering and international projects to simplify learning.
Why Study GIS0:39
Explore why GIS matters by analyzing economic development, environmental impact, and monetary sensitivity, and assess food security analysis, sustainable land use, natural resources, and asset management like vehicle tracking.
Trainer Profile0:32
Combine science and engineering techniques with enthusiasm to disseminate geographic information and support sustainable development, drawing on more than ten years of experience with the South African Development Community.
Course Introduction1:09
Geographic information system simplified introduces GIS fundamentals with no prerequisites, offering short review sessions and 24/7 video access. Learn basic GIS elements, databases, data structures, and image interpretation.
Earth Features0:53
Explore how a geographic information system represents earth features, from cropland and built-up areas to airports and beaches, and distinguishes discrete, countable features from others.
Information0:35
Identify entities above and below the SFE, and describe information comprised of codine and attributes to define features as objects and classify them as indigenous or scientific.
Systems0:31
Explore how systems—from human data to the global positioning system—work together to produce maps and graphical information, enabling improved knowledge of their features.
Morden GIS Definition0:37
Geographic information systems define a collection of components such as software and operating systems used to capture, query, and present spatial information about buildings, transportation routes, water, and schools.
Traditional GIS Definition0:26
Geographic information systems are computer-based tools that analyze, manipulate, and visualize geographic data on maps, enabling creation, management, and analysis with parameters like distance, area, volume, and height.
GIS History0:56
Explore the history of geographic information systems (GIS), from early approaches to the first functional information system developed in Ottawa for forestry, agriculture, and environmental data analysis.

GIS Federal Agencies
Federal agencies modernized GIS data management from 1996 to 2010, expanding data sources and disseminating information in multiple formats, including mobile and live feeds, via EPA and European Space Agency.
GIS Sites0:12
Explore gis sites and essential online mapping tools, including Google Maps and open road map, as you review research and innovations in geographic information systems.
GIS Data2:58
Explore how geographic data uses points, lines, and polygons to represent features in x,y coordinates, and how rasters and triangulated irregular networks create elevation models for planning.
Raster Formats0:10
Explore raster formats and how format choices influence performance across devices like CW EPM, iPad, and PDA in geographic information systems.
Raster Resolutions2:16
Explore four raster resolutions—spatial, spectral, radiometric, and temporal—and how color combinations (blue, green, red) and pseudo color schemes with 0–255 brightness levels shape GIS imagery from UAVs and satellites.

GIS Methods Overview0:19
Geographic information system simplified presents a GIS methods overview, showing how a production method NGO coordinates capturing, treating, and digitizing data in one place to enable growth.
GIS Methods Cont'd0:58
Explore continued GIS methods for producing data from various sources, including digitizing images to create quantitative data and defining polygons.
Phenomenal Information Extraction Methods3:35
Explore land cover classification methods: supervised, unsupervised, and object-based approaches, and how training sites and differential change vector analysis support change detection.
Spatial Analysis0:24
Explore spatial analysis techniques to explain co-feature among location, proximity, change detection, and coverage probability, using queries, overlays, and modeling.
Elements of Image Interpretation3:16
Identify and analyze image elements such as shape, size, color or contrast, pattern, texture, shadow, location, height and depth, and shape and form to interpret geographic objects.

Database0:51
This lecture explains how a geographic information system database stores activity data tied to points and features, with columns for location, construction date, who built, why, and satellite imagery.
Database Structure1:10
Explore data structures in databases for geographic information systems, including text and date fields, identity numbers, and how data is organized across levels to support search and time features.
GIS Software0:22
Explore the evolution of GIS software from 1978 to 1987, examining diverse programs developed by various organizations.
GIS Requirements1:09
Outline GIS requirements by detailing necessary hardware, software, operating system, display properties, graphics adapters, network hardware and drivers, .NET framework, Internet Explorer, printer drivers, and supported Windows platforms.

Coordinate System1:06
Explore how coordinate systems establish reference points and a zero baseline to measure location, using the earth's x-axis and compass directions across hemispheres.
GIS Map Projections0:31
Explore GIS map projections focusing on the UTM system, showing how the earth is divided into six-degree zones from a zero degree reference and how this affects geographic data.
Validation of GIS Maps0:30
Explore validation of GIS maps and the role of quality management in ensuring reliable results, using diverse approaches and knowledge checks to verify methods.
Conclusion0:14
Thank you for attending this course, and congratulations on completing the geographic information system simplified course. We look forward to seeing you in the next session.
