Last time we talked on why PostGIS should be the database friend of a GISer , and we touched on most of the features that sets the GIS PostgreSQL extension far from any other spatial database. Of course, PostgreSQL is not the only spatial database that can get your work done, and as one of our readers had suggested, today we will be looking on why and when should choose between PostGIS and SpatiaLite. First things first. SpatiaLite is a variant of the SQLite database that also provides GIS features. It uses the GEOS, PROJ.4, etc... libraries that are also used in PostGIS, and hence the resulting feature set is similar. So what is the difference between the two ? Which one should you pick? Lets find out through a side by side comparison. 1.Scale of Project SpatiaLite is probably t...
This is my very first step in GIS and web mapping to be specific. Being in my first year in campus, I have this passion for GIS that drives me out of the norm to explore and learn new things that come my way. It took hard work and determination and I finally came up with a story map app. I had to ignore the fact that I had very little knowledge of this course. The app that I created did not come out of the blues nor did I just wake up and do it. It required the know-how to create it. So, I enrolled for an online course from Udemy that I was able to learn the Esri program. I faithfully did the course and at the end of it I acquired the skills on how to make story map apps, geo-apps, native apps among others. This is when I came up with KENYA’S BIG FIVE map story. The web map can be accessed
Navigating through Global mapper software can be somehow difficult or even confusing if you don't have the hands-on skills on how to use the different tools found in this software. To help in learning more about some of the features found in this software, I have done an explainer video on the computation of volume between surfaces, for anyone to use and learn quickly on these tips and tricks. Find the video below; https://youtu.be/zCwZbtFJQTA On more ideas or inquiries about this, leave a comment below!
GIS side hustle projects are a great way to generate extra income as well as learn more than what your daytime job offers as a challenge.

So how do you earn that extra coin while maintaining high productivity within your normal working hours? Once you factor in sleeping hours and an 8 am to 5 pm schedule you are left with so little time to pursue GIS programming, data science, image analysis, academic writing or even blogging. That means you have to implement a few tactics to avoid overworking yourself. Below are 4 ways to balance between your full-time job with your GIS side projects. Prioritize your work You must have the big picture in mind if you want to be ef...
So you have heard of fancy GIS job titles out there and you wonder what they mean, or what exactly the guys in those capacities do. You want, say , to be a GIS analyst, but don’t know the right requirements for you to be able to fit in. Or you are puzzled in the difference between a GIS developer and a GIS programmer. This article is just for you. GIS has evolved over the past years, and so is everything associated with it, including these job titles. Well, you will agree with me that there is no formal uniformity or consistency in the naming of these titles, because this greatly varies with an organization, and you may find that a certain GIS position has the similar duties, responsibilities or qualifications as another one. But with that said, here are some of the common GIS job title
For this article I would like to compare GIS to a very expansive forest that is constantly breaking its banks and invading coastal towns. The waters of GIS have swamped fields such as business, health and are now encroaching into the least likely of places; GIS and gaming. I am almost 90% certain most of you crinkled your brows in skepticism when you saw the title. However, I kid you not, GIS has found a way to brilliantly embed itself into the gaming industry. Video games, besides being a major mode of entertainment for majority of today’s youth, kids and adults as well. Hence it is a great avenue for education about history or certain aspects of modern day life. There was a dying need for games to be more than just entertainment. Gaming companies are going neck to neck looking for new
The Young Surveyors Network has launched the Jadili initiative, an initiative meant to enhance innovation and participation of the young surveyors in ISK. The initiative will focus on organizing talks and meetings every two months to foster growth among the professionals and also discuss on important matters in different topics. The first meeting is will be held on 24th February as indicated below. The Jadili initiative comes at a time when the need for achievable solutions to problems in the survey industry are required than ever. In order to grow the profession, dialogue between different parties and players in the industry is required.
A month ago, I met some guys preparing for a GIS job interview in one of the companies in town. Some looked confident for the interview while others seemed doubtful of the entire process. I had a chat with the guys, as a casual friend, as the first person went in for the interview. After roughly seven(7) minutes, the first guy joined the group from the interview room. He smiled and said to the friends, It wasn't that hard, just some questions that were mind cracking. I didn't bother asking the specific questions asked in there so as to avoid spoiling it for the other guys. This is the reason as to why am writing this post to help others or give a rough idea of what goes on in an interview room. I have highlighted top questions that I have found common in most interviews for GIS jobs. Wha
The Mara Mapping Party was hosted by Upande LTD in Nairobi in collaboration with ITC in the Netherlands, UNESCO-IHE and Wageningen University and Research. The event brought together mappers and GISers from different institutions within the three regions to discuss the usefulness of the the Geospatial technologies in different sectors. With a number of demo sessions of completed and ongoing projects on mapping, the professionals were able to discuss exhaustively on issues pertaining to this topic of interest. The interactive sessions between the three groups were also so much fun as great topics were discussed amongst the members. Some of the topics discussed include; Mau Mara Serengeti Sustainable Water Initiative (MaMaSe) by Prof. Michael McClain from UNESCO-IHE, Mara Rangeland
When it comes to developers' options for geo-enabling their applications be it a desktop, Mobile and Web Apps, ArcGIS Engine has been the venerable choice especially for enterprises that can fulfill the EULA and pay the license fee. And this has been for a number of reasons we are already very aware of, ruling out the usual cliche of "good support" ~ 90% of the support you get from online forums not the time you spend on phone calls with professional services. ArcGIS Ecosystem provides a lot geospatial capabilities from Server technology, desktop, cloud and a number of other frontier technology offerings. ArcGIS Engine has give birth to a number of useful developer toolkits, APIs and SDKs and for this it naturally becomes the "enterprisy" choice to ride on for development needs. Especially
