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.
