How GIS affects your everyday life

How GIS affects your everyday life

General, Industry, News
Do you wonder how spatial information affects your life? Do you find yourself questioning yourself whether GIS is very important? You don’t have to be a GIS professional to observe how location is integrated to almost everything in the modern day. Below are several ways how GIS can impact your life. A few years back, geo-technology was not appreciated well enough in Kenya. However, that is not the case anymore. Geospatial knowledge is now being used as the key to unlock how we understand our environment in very many ways. From the basics to specialization, tools to techniques GIS can greatly impact your life even without you knowing. GIS information or data being used as evidence in a court of law is a great example. Although digitally produced information does not hold water in cour

In your Geospatial python scripting endeavors, you are more than likely to manipulate various GIS raster data formats. Basically raster data is a combination of valued cells organized in rows and columns. It is this difference in resolution compared to other digital images that allows Python to exploit information that is very important in analysis of raster images. For example, the various bands of a multi-band image vary in wavelength which gives a developer the ability to extract very meaningful information. Scientific computation algorithms have now matured enough to process all GIS raster data formats that are currently available. Below are the raster data formats that you can process using Python programming language: TIFF (GeoTIFF) TIFF stands for Tagged Image File Form...

Today, companies are producing huge amounts of data in terms of volumes in their offices and work places.This has led to large files in data stores or even more server space to store this data.Compared to traditional ways or days, where data was collected and then pre-processed, data nowadays is ready for use into different areas making work easier and faster.This has been made possible by algorithms running in some servers somewhere or offices like yours or mine e.g. Google Servers or Social Media sites like Facebook. Implementing these techniques of machine learning, enhancing insights and developing better knowledge base has led to the great technology era we are experiencing at the moment. As evident at Mastering Python data visualization , accurate and correct data leads to better inf...
QGIS misbehaves with csv, txt occasionally!

QGIS misbehaves with csv, txt occasionally!

Nicholas Duggan in his article in XYHT magazine describes an epiphany that can only be described as the "devil in the detail" of his experience while attempting to do what most of us would naturally do, the least place you'd want to look. I'm sure you've once or twice found it easy to just drag that .shp or any other file into QGIS Map Canvas and went on with your work like usual. Well, maybe you'll have to think twice about that shortcut next time you have a .csv or .txt file to open in QGIS; this is what will happen to you. Read through Duggans article on his experience with this...just to give you a heads up Duggan was demonstrating to QGIS new users then things didn't go so well.
