WHEN AND WHY YOU NEED GEOSPATIAL DATA. SIX COMMON QUESTIONS ANSWERED.
The Western Canadian Sedimentary Basin (WCSB) is rich in resources compared to other regions in Canada. This creates a higher demand for land use and consequently an increased demand for preservation. With all of this interest in resource information, organizations require geospatial data to inform decisions.
What is geospatial data used for?
This data is used for planning & disaster mitigation, monitoring and reporting, as well as, to inform design and development decisions. More specific examples include:
- Flood Plain Modeling
- Logistics & Communications
- Utility Corridors
- Forestry-fire management
- Environmental Analysis and Archeology
- Coastal Erosion and Study
- Emergency Planning
- Oil and Gas Exploration and Development
- Transportation- RR, Hwy, Airports
- Land Development- Subdivisions, Infrastructure
Who is using geospatial data?
The organizations that typically require this data are municipalities, cities and towns, plus engineering, pipeline, oil & gas, surveying, geomatics, environmental and mapping companies.
What are the various types of geospatial data?
Orthophotography, High Resolution Satellite Imagery, Aerial Photography; Stereo Imagery & Aerial Triangulation, Photogrammetric Elevation Data and LiDAR.
Is free geospatial data worth it?
Simply put, no. The quality doesn’t compare and it is not worth putting your project at risk of failing or your analysis at risk of containing incorrect information.
Drone Versus Fixed Wing Aerial Photography
Drones are lightweight and portable and can be deployed quickly to capture low altitude imagery. Drones mounted with cameras are ideal for commercial applications such as:
- Capturing breaking news
- Visual inspections of water towers, wind turbines and other infrastructure
- Damage, hazard and crisis assessments
- Marketing real estate
- Short battery life limits each flight
- Can’t cover large areas quickly, flights are limited to the neighborhood level
- Small, inexpensive cameras
- Drones can’t go too far away from the operator. If you’re inspecting a hazardous situation, you still need to get relatively close.
- Regulations limit altitudes and distances to structures and airports.
- Legal and privacy concerns.
- Drones are impacted by localized weather phenomena, vibrations, and exposure to dust and airborne debris on the sensors.
Fixed Wing Pros
The higher costs to operate a fixed wing plane can be easily justified.
- Covers large areas quickly, a city can be imaged in just a few hours
- Higher quality camera with separated spectral bands and longer focal length
- The weight of sophisticated camera equipment, gyroscopes, GPS etc needed for good quality ortho imagery can easily be carried
- Data security and redundancy
- Value added products created from imagery like elevation mapping are possible; imagery remains relevant and useful longer
