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?
These are 10 useful Geospatial Data portals, We have decided to list 10 of those that we have found most useful, rich with content, easy to use, and with metadata that is available and understandable. In considering such a list, we realize that “most useful” really depends on the application that one is using GIS for, but the following sites should be useful for users in many disciplines. Some allow for data to be streamed from web servers into your GIS software, and all allow data to be downloaded.
The platform offers the fastest engine to search and process satellite and areal imagery I’ve ever seen. On the top, it features a massive set of filters and algorithms to analyze the data at any scale. Now, all these features are available for free to the general public. The company recently launched a new, impressive web-based tool where anyone can access, analyze and download satellite images for free.
The USGS Earth Explorer is a similar tool to the USGS Global Visualization Viewer (GloVis) in that users search catalogs of satellite and aerial imagery. The USGS Earth Explorer is the new and improved version.
