Levels of Use of a GIS

Levels of Use of a GIS

Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...

Design Example: Alignment of a Road Line Using GIS

Design Example: Alignment of a Road Line Using GIS

The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

GIS Software, Hardware, and Sources of GIS Data

GIS Software, Hardware, and Sources of GIS Data

A Geographic Information System (GIS) combines specialized software and hardware to effectively manage, analyze, and present spatial and related data. GIS software includes critical functionalities such as a user interface for easy navigation, database management tools for handling spatial and attribute data, and data retrieval features for efficient access. Analytical tools transform raw data into insights, while display functions produce maps and reports in various formats for effective...

Introduction to GIS

Introduction to GIS

Geographic Information Systems (GIS) are tools for storing, analyzing, and displaying spatial data alongside related attributes. Unlike traditional information systems that address general queries, GIS incorporates spatial components, enabling users to answer "where" and "how far." For example, GIS can process housing data linked to geographic locations like zip codes, allowing insights into population density or housing distribution through thematic maps.GIS integrates technologies such as...

Multiple Bar Graph

Multiple Bar Graph

As the name suggests, a multiple bar graph is the same as a bar graph but has multiple bars to depict relationships between different data values. One can include as many parameters as possible. However, each parameter must have the same unit of measurement.
Each bar or column in the multiple bar graph represents a data value. These graphs are used primarily in interrelating two or more sets of data. The categories of different kinds of data are listed along the horizontal or x-axis, whereas...

Plotting of Topographic Maps

Plotting of Topographic Maps

Topographic maps represent the Earth's surface features using contour lines, which connect points of equal elevation to create a two-dimensional representation of three-dimensional terrain. Creating a topographic map requires a systematic approach.Begin by plotting a scaled grid and marking intersections corresponding to the survey's elevation data points. Assign elevation values at these intersections to build the base map. Next, determine contour levels using a consistent contour interval,...

Area of Science:

Data Visualization
Geographic Information Systems (GIS)
Human-Computer Interaction

Background:

Area cartograms visually represent data by resizing map regions proportionally.
Contiguous cartograms preserve spatial adjacencies, crucial for accurate geographic representation.
Existing cartogram software often lacks accessibility for non-technical users.

Purpose of the Study:

To review available contiguous cartogram software.
To compare the usability of two web-based tools: fBlog and go-cart.io.
To identify challenges and propose improvements for web-based cartogram generation tools.

Main Methods:

Literature review of contiguous cartogram software.
User study evaluating cartogram generation and analysis tasks.
System Usability Scale (SUS) for quantitative usability assessment.
Qualitative feedback collection on user challenges.

Main Results:

Participants rated go-cart.io as more usable than fBlog.
go-cart.io offers more built-in maps and supports file uploads for data.
Both tools exhibit usability issues, with go-cart.io's complex interface and limited data import formats being key concerns.

Conclusions:

Web-based contiguous cartogram tools show promise but require significant usability enhancements.
Recommendations are provided for improving go-cart.io and future web-based cartogram software.
Enhanced usability is critical for broader adoption of area cartograms by non-expert users.
