How to Find, Evaluate, and Effectively Use Geospatial Data in GIS: A Step-by-Step Guide

In today's data-driven world, geospatial data has become essential for businesses, researchers, and governments to make informed decisions. Whether you're working in urban planning, environmental science, logistics, or other fields, the ability to locate, evaluate, and use geospatial data effectively in GIS (Geographic Information Systems) can make a significant impact. Here’s a step-by-step guide to help you through the process of working with geospatial data to maximize its potential in your GIS projects.

Step 1: Understanding Geospatial Data and Its Types

Before diving into finding geospatial data, it's essential to understand its forms and applications. Geospatial data represents geographic information, typically in terms of latitude, longitude, and elevation. The data comes in two main types:

Raster Data: Composed of grid cells or pixels, such as satellite imagery or aerial photographs.

Vector Data: Includes points, lines, and polygons, used to represent specific features like roads, city boundaries, and infrastructure.

Understanding which type of data is needed will set the foundation for your project.

Step 2: Identifying Your Data Needs

Define the scope and objectives of your project. Questions to ask include:

What area does the project cover? Identify the geographic scope.

What data variables are required? For example, temperature, elevation, or land cover types.

How recent should the data be? Some projects require real-time data, while others may use historical data.

What resolution or detail is needed? Higher resolution is useful for local analyses, while lower resolution might be sufficient for regional or global projects.

With this information, you can start searching for the appropriate data sources.

Step 3: Finding Reliable Sources of Geospatial Data

Many public and private organizations provide access to geospatial data. Here are some popular sources:

Government Databases:

USGS Earth Explorer: Excellent for US-specific data, particularly for geological and topographic information.

NASA Earth Data: Free datasets for satellite imagery and climate information.

Copernicus Open Access Hub: Provides data from the European Union's Sentinel satellites.

Global Databases:

OpenStreetMap (OSM): A community-driven mapping platform, providing access to vector data like roads and landmarks.

Google Earth Engine: A robust platform offering global-scale geospatial datasets and processing capabilities.

Natural Earth: Free vector and raster map data at different scales for global use.

Commercial Data Providers:

DigitalGlobe and Planet Labs: These companies offer high-resolution satellite imagery and geospatial data, typically on a paid basis.

For more specialized datasets, reach out to academic institutions or industry-specific organizations. Once you’ve identified potential sources, move on to evaluating the data.

Step 4: Evaluating Geospatial Data Quality

Once you’ve sourced your data, it's critical to assess its quality to ensure it meets your project's requirements. Consider the following factors:

Accuracy: Ensure the data aligns with real-world measurements. Vector data should match the geographic reality, and raster data should align with known resolutions.

Timeliness: Is the data up-to-date, or is historical data sufficient? Projects that monitor trends over time might require datasets spanning multiple years.

Completeness: Verify that the dataset covers your entire area of interest without gaps.

Reliability: Look for metadata, which provides details about data collection methods, processing, and sources. Reliable data is usually backed by documentation.

Compatibility: Ensure the data format (e.g., shapefile, GeoTIFF, KML) is compatible with your GIS software. Most GIS platforms support common formats, but it’s best to double-check.

Evaluating data quality can help avoid costly errors and inaccuracies during analysis.

Step 5: Processing and Cleaning Geospatial Data

Geospatial data often requires cleaning and processing to prepare it for analysis:

Projection and Coordinate Systems: Ensure all data layers use the same coordinate system. Misaligned layers can lead to inaccurate spatial analyses.

Data Transformation: Adjust formats as needed to fit your analysis. For instance, raster data might need to be reclassified for thematic mapping, while vector data may require simplification.

Error Correction: Check for and correct errors like missing values or outliers.

Resampling: For raster data, resampling may be necessary to match different resolutions across datasets.

These steps prepare your data to integrate seamlessly in GIS, minimizing errors during analysis.

Step 6: Conducting Geospatial Analysis in GIS

Once the data is clean and ready, GIS provides powerful tools to analyze and interpret it. Here are a few common types of geospatial analysis:

Spatial Analysis: Use tools like overlay, buffering, and spatial joins to find relationships between different datasets. For example, analyze how close schools are to certain environmental hazards.

Temporal Analysis: For time-based data, use temporal analysis to observe changes over time. This is useful for tracking urban growth, deforestation, or climate patterns.

Statistical Analysis: GIS platforms offer statistical tools that allow you to quantify spatial patterns, helping in hotspot analysis or population density mapping.

Predictive Modeling: Create models that use spatial data to predict future trends, such as urban sprawl or wildlife habitat migration.

Each type of analysis provides unique insights to support data-driven decisions.

Step 7: Visualizing and Presenting Geospatial Data

Good visualization makes data insights accessible. Use GIS tools to create clear, informative maps, and customize visualization elements:

Layering and Symbology: Adjust colors, symbols, and labels to represent different data types clearly. For example, use blue for water bodies and green for vegetation.

Classification: Group data into meaningful categories, like low, medium, and high elevation, for better interpretation.

Legends and Scale Bars: Include legends, scale bars, and north arrows to make maps easy to read and understand.

Presenting data in visually appealing formats enhances comprehension and effectively communicates your findings to stakeholders.

Step 8: Sharing and Storing Your Geospatial Data

Once your analysis and visualization are complete, you may want to share it with others or store it for future use:

Export Options: Most GIS platforms allow you to export maps in various formats, such as PDFs, JPGs, or online interactive maps.

Data Sharing Platforms: Platforms like ArcGIS Online and QGIS Cloud make it easy to share data and maps with collaborators.

Data Storage: Geospatial data files can be large, so store them in a secure location. Cloud storage solutions like Google Drive, Dropbox, or Amazon S3 provide scalable options.

Following these steps ensures that your data is preserved and accessible for future projects.

Meta-learning to find every needle in every haystack - Technology Org

The quest to efficiently identify regions of interest in geospatial exploration has recently taken a leap forward with visual active search (VAS). This modeling framework uses visual cues to guide exploration with potential applications ranging from wildlife poaching detection to search-and-rescue missions to identifying illegal trafficking activities.

A new framework for visual active search developed by McKelvey engineers leverages reinforcement learning to improve search performance. An adaptive search approach initially makes a mistake but quickly adapts by learning from it. Image credit: Anindya Sarkar

A new approach to VAS developed at the McKelvey School of Engineering at Washington University in St. Louis combines deep reinforcement learning, where a computer can learn to make better decisions through trial and error, with traditional active search, where human searchers go out and verify what’s in a selected region. The team that developed the novel VAS framework includes Yevgeniy Vorobeychik and Nathan Jacobs, computer science and engineering professors, and Anindya Sarkar, a doctoral student in Vorobeychik’s lab. The team presented its work at the New Orleans Neural Information Processing Systems conference.

“VAS improves on traditional active search more or less depending on search task,” Jacobs said. “If a task is relatively easy, then improvements are modest. But if an object is very rare — for example, an endangered species that we want to locate for wildlife conservation — then VAS offers substantial improvements. Notably, this isn’t about finding things faster. It’s about finding as many things as possible given limited resources, especially limited human resources.”

The team’s VAS framework improves on previous methods by breaking down the search into two distinct modules. The framework first uses a prediction module to produce regions of interest based on geospatial image data and search history. Then a search module takes the resulting prediction map as an input and outputs a search plan. Each module can be updated as human explorers return results from physical searches in real time.

“Instead of an end-to-end search policy, decomposing into two modules allows us to be much more adaptable,” Sarkar said. “We can update our prediction module with the search results during the actual search. Then the search module can learn the dynamics of the prediction module — how it’s changing across search steps — and adapt. In this meta-learning strategy, the search module is basically learning how to search. It’s also human interpretable, so if the model isn’t working properly, the user can check it and debug as needed.”

The major strength of the framework comes from its ongoing incorporation of two deployment levels: the computational model predicts where to search, then humans go out into the world to search. The human component is vastly more expensive in terms of time and other resources required to explore large geospatial areas, so it makes sense to adapt and optimize the computer-generated search plan for a maximally efficient search.

Adaptability in the computer model is especially important when the object sought varies drastically from the objects the model is trained on. Experimental results showed marked improvement by Sarkar, Vorobeychik and Jacobs’ proposed VAS framework over existing methods in various visual active search tasks.
