With rapid urbanization and growth of the city, urban planning has received a major importance. This planning is done at various hierarchies to integrate a large region with a small area so that the development is done at a same pace. There are many legal documents made to promote development. Master plan is one such document which provides rules and guidelines for a planned development both at present and future.
Houston exulted in sprawling, hands-off growth. That’s no way to prepare for natural catastrophes.
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.
