Privacy And Ethical Considerations With Expanding Gis Data

Expanding Access to Location Data

As geographic information systems (GIS) become more sophisticated and location-enabled devices more ubiquitous, the amount of geographic data available is rapidly expanding. This creates tremendous opportunities for spatial analysis to inform decisions, but also risks to individual privacy and ethical pitfalls if not handled carefully.

Balancing open data with privacy

Governments, companies, and researchers are making more geospatial datasets publicly available in the name of open data. However, these datasets often contain precise location information that could reveal details about individual behaviors, addresses, daily routines, etc. Techniques like aggregation and differential privacy help balance the benefits of open geographic data with individual privacy rights.

Techniques for protecting personal information

Releasing geographic data risks exposing individuals’ home and workplace addresses, daily movements, socioeconomic details, and more. Several techniques allow organizations to share geographic data while protecting personal information:

  • Aggregation: Combine data to broader geographic levels to avoid pinpointing individuals.
  • Differential privacy: Add statistical noise to data to mask individual records.
  • Redaction: Remove attributes that could identify individuals from a dataset.
  • Restricted access: Limit dataset access to qualified researchers with non-disclosure agreements.

Aggregating data to avoid identification

Aggregating geospatial data to lower geographic resolution, such as neighborhood or census block rather than individual addresses, helps prevent identifying specific people from the data. Researchers can still conduct valuable analysis on trends and patterns without compromising privacy through aggregation techniques.

Ethical collection of geospatial data

Geographic data holds clues to many private, personal behaviors and attributes. As location-tracking technologies advance, researchers much take care in data collection, storage, and use to avoid harms. Key principles include transparency in how data is gathered, allowing individuals access to their own data, and securing informed consent wherever possible prior to data collection.

Responsible Use of Geospatial Analytics

Sophisticated GIS software allows users to conduct detailed spatial analysis to uncover geographic patterns. However, these techniques also risk misuse such as discrimination, violation of privacy, or reliance on flawed analysis. Researchers and analysts should adhere to ethical principles including considering analysis implications, allowing public scrutiny, and focusing methods on progress over profit.

Potential for discrimination based on location

Analysis combining demographic data with locations may reinforce existing stereotypes and biases against marginalized groups concentrated in certain neighborhoods. Users should take care to put findings in proper context and not overstate conclusions or generalizations based on correlations in spatial data.

Considering unintended consequences of spatial analysis

Geospatial analysis frequently informs major decisions like store locations, insurance rates, transportation planning, and more. Analysts must consider the unintended social consequences of these choices to avoid unfairly disadvantaging or overlooking certain communities.

Transparency in analysis methods and data sources

GIS experts should fully document data sources and analysis steps taken to reach conclusions from spatial data. Methodology transparency allows the public and colleagues to assess the validity and limitations of findings, replicating successful techniques while also identifying possible faults or biases.

Allowing individuals access to their own location data

Individuals should have reasonable access to view and correct any private geographic data about them collected by governments, companies or other entities. This ability allows people to audit data accuracy and request changes or removal of details they are uncomfortable with.

Building Inclusive Geographic Information Systems

Historically geographic data has overlooked groups like low-income neighborhoods and Indigenous communities while focusing largely on wealthy, majority demographics. Modern GIS projects should emphasize inclusiveness through thoughtful data gathering, system accessibility for diverse users, and collaboration with marginalized groups.

Accommodating marginalized groups

GIS practitioners should design data collection and analytics projects to represent and meet the needs of marginalized populations including disabled, elderly, low-income, and minority community members. Inclusive processes give voice to overlooked groups instead of further exclusion.

Designing accessibility features

Geographic information tools often lack accessibility features for vision, hearing, or motor impaired users. Prioritizing website, software and map accessibility expands GIS capabilities to disabled individuals through tools like screen readers, captioning or alt text for visuals, and interface modifications.

Supporting public contribution and community mapping

Community mapping initiatives encourage local residents to directly contribute geographic information about their neighborhoods. This participatory approach provides more detailed, accurate data about areas often missing from formal maps and databases while serving public interests.

Crowdsourcing efforts to expand geographic knowledge

Projects like OpenStreetMap tap the public’s local geographic knowledge to collaboratively build free and open map data. Supporting similar crowdsourcing and citizen science efforts helps render the previously invisible visible through community-led mapping.

Ongoing Challenges for Ethical GIS

Emerging location-tracking technologies raise new privacy questions and risks for misuse faster than policies and best practices evolve. Continual ethics education alongside appropriate regulation can help balance innovation opportunities with individual rights regarding geographic data use.

Evolving policies and best practices

Governments struggle to enact effective laws balancing open access to geospatial data with personal privacy protections given rapidly changing technologies. Meanwhile professional associations offer evolving voluntary codes of ethics for GIS practitioners.

Education on ethical spatial data use

Academic and vocational GIS programs must continually update curriculum including assignments tackling ethical scenarios with geospatial data privacy, integrity and analysis for decisions affecting human lives.

Monitoring emerging technologies and applications

Consumer location tracking in smartphones, spatial media like Snapchat, connected vehicles, drones and advanced visualization open innovative uses but require vigilant monitoring for possible ethical abuses as adoption grows.

Maintaining realistic expectations for GIS systems

As analytical power expands, users must remember geographic information offers clues requiring human context and confirmation before determining causal links. GIS can indicate areas needing attention but maintaining realistic expectations prevents overconfidence in data results.
