NDVI is the most common index that analysts use in remote sensing. But how do you calculate it? What do NDVI values represent? How do Earth scientists use NDVI?
You probably grew up using ArcGIS… or QGIS…and every day, you sit down at your computer desk…and you do the same thing: You open up the same ArcGIS software…or QGIS software (albeit a newer version) because that’s what you know best.But have you ever asked yourself,Can I get MORE from using different GIS mapping software?
You don’t have to pay a king’s ransom to map the world. This is because you can do it all with free GIS software.
The best part is: These free GIS software give you the firepower to get the job done as if you’re working with commercial GIS software.
Jack Dangermond is an innovator par excellence, the Godfather of spatial analytics, the founder of Esri – the world’s biggest GIS software company. Jack Dangermond is the reason why the sprawling San Diego Convention Center has been buzzing like a beehive since Monday morning; the reason why more than 17,000 geo-geeks have travelled from over 130 countries to assemble at one place; the reason why city Mayor Kevin Falconer felt compelled to declare July 10 as the ‘Esri User Conference Day’.
GIScience is Concerned with How to Build Better Geographic Information Systems. While Geographic Information Systems answers the “what” and “where”, Geographic Information Science is concerned with the “how”.
There are several ways to help readers understand distance and map scale. Maps are generally never the same scale as the real world. This is why cartographers use scale bars that compares a map distance to an actual distance.
Not only do scale bars, ratio and stated scales can also show size and distance in a way that people understand, but inset maps help understand map scale.
Smart city is the city of tomorrow, which tries to identify a smarter option from legacy system for maximizing the end-user satisfaction and accelerating urban socio-cultural and economic development. Smart city is knowledge based city functioning on most latest and updated information on automated decision-making and rapid action for individuals.
The GIS software options out there seem endless. ArcGIS, QGIS, GRASS GIS, SuperGIS, SAGA GIS, JUMP GIS… The range of GIS products to choose from can get a bit “ridiculous” at times. Don’t worry. You map out solutions to real-life problems every day. You just need someone to map out the GIS software landscape for you.
How would you like to wave your magic wand and all of a sudden find out how far everything is away from you? No magic wands necessary. This is how LiDAR (Light Detection and Ranging) works – minus the magic wand.
You hear these buzzwords almost every day but what is the actual meaning of Artificial Intelligence, Machine Learning, and Deep Learning… Are these terms related and overlapping? What’s the technology behind it? And what are their applications in the geospatial industry?
