What is Geostatistics?
Geostatistics is the study of statistics with a focus on finding patterns of geographic phenomena using variograms, kriging and validation.
Sentinel 2 Bands and Combinations
Sentinel 2 has a total of 13 bands. Each band is 10, 20 or 60 meters in pixel size. This includes red, green, blue, near infrared and short infrared bands.
Where is the Central Meridian?
The central meridian is the center line of longitude for projection systems. Projected coordinate systems often use it as a reference point for a x-origin.
How to Track the Spread of Viruses Using GIS
Everyday, communities are at risk of transmissible diseases and growing pandemics like COVID-19. We use GIS to track the spread of viruses in real-time maps.
Mango Map Review – Simplicity is Sophistication
Mango Map is ideal for casual users who don’t want a fancy map. This web mapping platform is easy to get a hang of at a reasonable price.
What is Geodata? A Guide to Geospatial Data
Geodata is location data stored in a Geographic Information System (GIS). By using geographic data, we better tackle problems that require spatial thinking.
Internet of Things (IoT) in GIS
The Internet of Things (IoT) connects billions of sensors from around the world, enabling the exchange of information between them.
AVHRR: Advanced Very High Resolution Radiometer
AVHRR (Advanced Very High Resolution Radiometer) spatial resolution is actually very coarse at 1.1 km. But its revisit times are “very high” at just one day.
Geodesign: Integrating Geography and Design
Geodesign is the field of study that combines geography with design. Design shapes our world by addressing the needs of people and promoting more resiliency.
