As most know, Airborne Sensor Operators (ASO) play a crucial role in collecting and analyzing data from various sensors mounted on aircraft, such as drones, survey, or reconnaissance planes. Geographic information systems (GIS) are essential tools for ASOs as they help collect, manage, analyze, and visualize spatial data. So, how do GISs assist ASOs, and what are some of the traditional GIS platforms used by ASOs today?
Related ASO GIS Functions
Regarding how GIS technology integrates into the daily life of an ASO, it ranges across the full spectrum of sensor operator duties. Here's how ASOs routinely use geographic systems:
- Mission Planning - GIS is used to plan flight paths and define the areas of interest for data collection. This involves identifying geographic coordinates, altitude, and timing for the mission.
- Sensor Configuration - GIS is employed to configure sensors and ensure they are set up correctly to capture the required data, such as aerial imagery, thermal data, LiDAR scans, or multispectral imagery.
- Real-time Monitoring - During the flight, GIS software helps operators monitor the aircraft's position, altitude, and sensor status in real time. This ensures that data is being collected as planned.
- Data Collection - Geographic systems enable operators to synchronize sensor data with the aircraft's GPS coordinates. This spatial reference is crucial for accurately geo-referencing the collected data.
- Data Management - GIS organizes and manages the vast amount of data collected during a mission. This includes storing, indexing, and cataloging data files for future analysis.
- Data Analysis - Geographic systems provide tools for operators to analyze the collected data. They can overlay different layers of information, perform spatial queries, and extract valuable insights from the data.
- Quality Control - GIS tools help operators check data quality by comparing collected data to reference layers or aerial imagery. Any anomalies or errors can be identified and corrected.
- Reporting and Visualization - Geographic systems allow operators to create maps, reports, and visualizations to communicate findings effectively. This is crucial for decision-makers and stakeholders who may not be GIS experts.
- Geospatial Integration - Operators often integrate data from airborne sensors with existing geographic information, such as maps, land use data, or infrastructure details. This integration enhances the value of the collected data.
- Post-Mission Analysis - After the mission, GIS tools help operators conduct in-depth analysis, such as change detection, terrain modeling, or environmental assessments, using the collected data.
- Archive and Retrieval - GIS systems assist in archiving and indexing mission data, making retrieving and referencing for future missions or research easier.
- Collaboration - Geographic systems facilitate collaboration among operators, analysts, and other stakeholders by providing a common platform for data sharing and discussion.
Overall, using geographic systems by ASOs ensures efficient and accurate data collection, analysis, and reporting, vital for various applications, including environmental monitoring, disaster response, agriculture, and defense.
Traditional GIS Platforms
As mentioned, ASOs use a variety of Geographic Information Systems (GIS) software tools depending on their specific needs and requirements. Here are some of the traditional GIS software commonly used by ASOs:
- Esri ArcGIS - Esri's ArcGIS suite is one of the most widely used GIS platforms globally. It offers a comprehensive range of data collection, analysis, and visualization tools. ArcGIS Desktop, ArcGIS Pro, and ArcGIS Online are some of the commonly used components.
- QGIS (Quantum GIS) - QGIS is an open-source GIS software that provides many features and functionalities similar to proprietary GIS solutions. It is known for its user-friendly interface and the ability to work with various data formats.
- ENVI - ENVI is a specialized software for processing and analyzing remote sensing data, making it particularly useful for ASO. It offers advanced image analysis capabilities.
- ERDAS IMAGINE - ERDAS IMAGINE is another popular software for remote sensing and spatial analysis. It supports various remote sensing data formats and provides image processing and interpretation tools.
- Global Mapper - Global Mapper is known for its ease of use and affordability. It allows operators to work with various spatial data types and perform 2D and 3D analysis.
- Trimble eCognition - Trimble eCognition is used for advanced image analysis and object-based image classification. It is valuable for extracting information from remotely sensed data.
- PCI Geomatics - PCI Geomatics software is focused on remote sensing, satellite imagery, and aerial photography. It offers tools for data preprocessing, analysis, and sharing.
- GRASS GIS (Geographic Resources Analysis Support System) - GRASS GIS is an open-source software focusing on geospatial data analysis and modeling. It's highly extensible and has a dedicated user community.
- Opticks - Opticks is open-source remote sensing software that provides tools for processing and analyzing geospatial data, including imagery and point clouds.
- L3Harris Geospatial ENVI SARscape - This software specializes in synthetic aperture radar (SAR) data processing and analysis, which is valuable for applications like monitoring changes in terrain and infrastructure.
Again, this is just a past and present view of some of the GIS platforms on the market. The GIS software landscape is dynamic, and new tools are continuously emerging. Additionally, the choice of GIS software depends on factors such as the type of data collected, the specific analysis requirements, budget constraints, and user preferences. Operators often select the software that best suits their needs and integrates well with their existing workflows. Therefore, it's essential to stay up-to-date with the latest developments in the GIS industry to make informed software choices.
Summary
As you can see, GIS platforms play a significant role in an ASO's daily job, i.e., from pre-flight to post-flight. A good understanding or knowledge of GIS is critical to being a professional ASO.
If you're interested in adding GIS experience or knowledge to your professional development to-do list, many online courses provide basic to advance training. Additionally, obtaining certifications related to GIS will enhance your value as an ASO and may open new career doors - hint, hint!
