Study Notes

Geographic Information Systems (GIS)

GIS is software for collecting, managing, analyzing, and displaying geographic data.
Used in various fields: industry, government, education, environmental monitoring, and conservation.

GIS in Civil Engineering

Improves city drainage, utility installations, and network planning.
Used for flood risk assessment, property valuation, and hazard identification.
Supports project management and data acquisition related to environmental conditions.

GIS in Telecommunication Services

Helps plan and manage telecommunication networks.
Includes tasks such as location allocation for mobile infrastructure, network layout design, and fixed/mobile network deployment.

GIS in Urban Planning and Management

Allows analysis, detection, and monitoring of land feature changes.
Supports urban planning decisions regarding resources (e.g., natural resources, traffic) and future infrastructure needs.

GIS in Business

Offers competitive advantage to businesses.
Includes functionalities for customer analytics, spatial planning, and disaster management.
Examples: retail strategy, travel time analysis, and store/shop site selection.

GIS in Disaster Management

Helps mitigate natural hazards (e.g., mapping and analysis).
Supports disaster management organizations for identifying vulnerable areas and planning effective responses.
Used for emergency services, route finding, and damage assessment.

GIS in Government

Used for various governmental functions like tracking natural disasters, managing crime patterns, and pollution levels.
Aids in efficient decision-making in various sectors.

Attribute Data

Attributes are non-spatial characteristics of geographic features.
Can be stored in tables or databases.
Four types: ordinal, nominal, interval, and ratio.

Attribute Queries

Used to select subsets of data based on attribute values.
Requires specifying: an attribute field, a set algebra operator, and an attribute value.

Data Types in GIS

Common data types: integer, float/real, text/string (character data), and date.
Integers represent whole numbers; floats/reals include decimal values.
Strings are character sequences; dates store time and date information.

Querying Strings

String searches within GIS are case sensitive.
Use the LIKE operator for partial matches.
Strings must be enclosed in single quotes.

Querying Numbers

Used with various operators like equal (=), not equal (<>), greater than (>), less than (<), and greater/less than or equal to comparisons.
Always use the point as the decimal delimiter.

Combining Expressions

Used to create more complex queries.
Uses AND and OR for combining conditions.
The NOT operator is used to exclude data points or records.

Thematic Maps

Maps focusing on specific themes or topics, using colors/symbols to represent data.
Types include: choropleth, dot density, isopleth, heat maps, and graduated symbol maps.

Choropleth Maps

Data values in geographic areas are represented with different colors.
Used to represent the concentration of data.
Advantages: fast and easy to understand, but can be manipulated to mislead.

Dot Density Maps

Data points are represented using dots to visualize density.
Advantages: accessible, easy to understand, and provide better visualization compared to heatmaps.
Disadvantages: requires careful consideration of context.

Isopleth Maps

Represent data using colors and shaded areas.
Data is contoured/divided into areas with similar data values.

Heat Maps

Varying shades indicate density.
Visual representation for market analysis and sales trends.

Graduated Symbol Maps

Use symbol sizes to represent data concentrations.
Useful for easily understanding large volumes of data.

Spatial Analysis

Studies locations, attributes, and relationships in spatial data.
Includes data integration, pattern detection, and modeling relationships.

Buffer Analysis

Creates zones around spatial entities (points, lines, or polygons).
Used to analyze proximity relationships.
Examples: identifying areas within a certain distance, like resource management or environmental impact assessments.
