How do you design and implement GIS modeling projects that are relevant, feasible, and impactful?

Spatial analysis and decision making are essential skills for GIS modeling, which involves creating and applying geospatial data and methods to solve real-world problems. Whether you are planning a conservation project, assessing urban growth, or evaluating public health risks, GIS modeling can help you understand complex spatial patterns and relationships, and make informed decisions based on evidence. But how do you design and implement GIS modeling projects that are relevant, feasible, and impactful? In this article, we will explore some key steps and considerations for successful GIS modeling, from defining your objectives and questions, to choosing the right data and tools, to communicating and validating your results.

1 Define your objectives and questions

Before you start any GIS modeling project, you need to have a clear idea of what you want to achieve and why. What is the problem or opportunity you are addressing? What are the main questions you want to answer? What are the expected outcomes and benefits of your project? These questions will help you define your objectives and scope, and guide your data collection, analysis, and presentation. You should also consider the needs and expectations of your stakeholders, such as clients, partners, or decision-makers, and how your project can meet them.

It's essential to acknowledge that GIS modeling projects often benefit from an interdisciplinary approach. Collaborating with experts from diverse fields, such as environmental science, urban planning, or public health, can enrich your project with a broader perspective and enhance its impact. This multidisciplinary input can lead to more comprehensive solutions and a deeper understanding of the problem or opportunity you're addressing.

To design impactful GIS modeling projects, first, define clear goals aligned with stakeholder needs. Assess feasibility considering data and resource constraints. Collaborate with experts to incorporate relevant factors. Keep the model simple and transparent for better understanding. Iterate based on feedback and validation. Communicate regularly with stakeholders, ensuring ongoing relevance. Document the process and results for knowledge sharing. This approach ensures that GIS projects are not only relevant and feasible but also have a lasting impact.

2 Choose the right data and tools

The next step is to identify and acquire the data and tools you need for your GIS modeling project. Depending on your objectives and questions, you may need different types of data, such as spatial, temporal, categorical, or numerical. You may also need to combine data from various sources, such as satellite imagery, surveys, census, or social media. You should evaluate the quality, accuracy, and relevance of your data, and make sure they are compatible with your tools and methods. You should also choose the appropriate software and platforms for your GIS modeling project, such as ArcGIS, QGIS, R, or Python, and learn how to use them effectively.

Choosing the right source for data collection can be crucial in its accuracy and relevancy. For example, when looking for shapefiles pertaining to forest fires, data coming from the Forest Service or climate organizations may be more accurate and abundant than data from county governments. However, when looking at land ownership, it would be wise to look for those shapefiles through county governments.

3 Perform spatial analysis and modeling

The core of your GIS modeling project is the spatial analysis and modeling process, where you apply geospatial techniques and methods to your data to answer your questions and achieve your objectives. There are many types of spatial analysis and modeling you can use, such as spatial statistics, interpolation, network analysis, suitability analysis, or multicriteria evaluation. You should select the methods that best suit your data and questions, and follow the principles of scientific inquiry and good practice. You should also document your steps and assumptions, and test and refine your models as needed.

In some cases, it may be necessary to clean your data and/or make it more specific to highlight what question you're trying to answer. For example, if you are examining grizzly bear population and your dataset includes all bear species, you should modify your scope so your map only pertains to grizzly bears.

4 Communicate and validate your results

The final step of your GIS modeling project is to communicate and validate your results. You should present your findings in a clear, concise, and compelling way, using appropriate visualizations, such as maps, charts, or graphs. You should also explain the meaning and implications of your results, and how they relate to your objectives and questions. You should also validate your results by checking their accuracy, reliability, and sensitivity, and by comparing them with other sources of information or feedback. You should also acknowledge the limitations and uncertainties of your models, and suggest possible improvements or future directions.
