GIS Project Site Analysis Documentation

Introduction

Geographic Information System (GIS) Project Site Analysis is a critical component in city planning and development control. It involves the use of GIS technology to evaluate potential sites for development projects based on various criteria and datasets. This documentation provides an overview of the process and steps involved in conducting a GIS Project Site Analysis, tailored for the needs of ACTDA, a city planning and development control agency.

Objectives of GIS Site Analysis

The primary objective of GIS Site Analysis is to identify the most suitable locations for new development projects by considering multiple factors such as land use compatibility, environmental constraints, accessibility, and infrastructure availability. The analysis aims to support informed decision-making and ensure sustainable development practices.

Steps in GIS Project Site Analysis

  • 1. Define the Problem and Objectives
    Begin by clearly defining the problem and the objectives of the analysis. This will guide the selection of relevant data and the analytical approach.

  • 2. Data Collection
    Gather spatial and non-spatial data relevant to the project. This may include topography, land use, zoning regulations, transportation networks, utility services, and environmental data.

  • 3. Data Preparation
    Prepare the collected data for analysis. This involves data cleaning, standardization, and integration into the GIS environment.

  • 4. Criteria Definition and Weighting
    Define the criteria that will be used to evaluate site suitability. Assign weights to each criterion based on its relative importance to the project objectives.

  • 5. Site Suitability Analysis
    Perform the analysis by applying the defined criteria and weights. Use GIS tools and functions to create a suitability model and generate a suitability map.

  • 6. Site Selection and Evaluation
    Identify potential sites based on the suitability map. Evaluate these sites further using detailed field assessments and stakeholder consultations.

  • 7. Reporting and Documentation
    Document the analysis process, findings, and recommendations. Prepare reports and visualizations to communicate the results to decision-makers and stakeholders.

Tools and Resources

ACTDA can utilize various GIS tools and resources for site analysis, including the Suitability Modeler, raster functions, geoprocessing tools, or ModelBuilder in ArcGIS Pro. These tools facilitate the creation of analytical models and the visualization of data.

Conclusion

GIS Project Site Analysis is a powerful tool for city planning and development control agencies like ACTDA. By following the outlined steps and utilizing appropriate GIS tools, agencies can make data-driven decisions that promote sustainable urban development.
