FIT FOR PURPOSE LAND ADMINISTRATION 

FIT FOR PURPOSE LAND ADMINISTRATION 

General, land matters, Opensource, QGIS
What is fit for Purpose? Fit for Purpose focuses on the "what" which is the purpose and "how" to achieve this purpose with the best ‘fit' design. Fit-for-purpose means that the land administration systems – and especially the underlying spatial framework of large scale mapping – should be designed for the purpose of managing current land issues within a specific country or region – rather than simply following more advanced technical standards. (Fit-For-Purpose Land Administration, 2014) Every country has its specific needs on their land sector, each with different forms of land ownership, different legal systems and also institutional frameworks. Therefore it cannot be the issue of one size fits all. It's evident that our current and past methods of our land administration hav

Build dynamic filters for values in drill down forms in QGIS with Form (Aware) Value Relation Widget.

General, Opensource, QGIS, Tutorial
The Form (Aware) Value Relation Widget is an enhancement of the QgsValueRelationWidgetWrapper which is available as a core component of the QGIS Edit Widget covered in this last post on creating dropdown lists in QGIS. This Plugin is available in the official QGIS Plugin Repository and the  source code is on Github. How the Plugin works internally; As a clone of the core Value Relation Widget already implemented in the core Edit Widget, Form Value Relation offers some cutting edge differences; the form refreshes the related item values on every change in the form values and that makes available the form values to the context. The expression is re-evaluated every time the form changes if the changed fields are part of the expression. A custom expression function "Curren

Top questions about GIS programming and their answers

General, Industry
It's been quite a while now since I started interacting with GIS and specifically, GIS programming. This is a field where I have met friends, mentors, role models and other people doing amazing stuff for our world. As evident in the Geo-Interview series, professionals are changing the lives of many through sharing knowledge and empowering societies through exchange programs both at individual levels and at organization level. It is most likely that your organization,county government or even country is developing a GIS portal for use in different sectors that exist in the area or within the mandate. Information systems have come of age and automating information dissemination has been a focus by many groups over the years. The emergence of initiatives such as Open Data and Open Standard...
Great business opportunities with open source software

Great business opportunities with open source software

General, Industry, Opensource
It's seven years since I heard and used a GIS for the first time. Back then, when my knowledge of GIS was limited to a few lectures that I had in my first semester of my degree programme back in college, the expectations of a great future with GIS were so high. I never understood the nitty gritty in this field. With time, I learnt a lot in terms of software, data analysis, data management, system development, web GIS and many more. From the beginning, data analysis, map making and data publishing was done in open source software. This was due to the lack of various licenses required to use proprietary GIS software on our personal computers. Having acquired skills based on these software, the industry looked so promising and had to up the game to meet the expected standards in the market. I...

Manage spatial data Versions like a pro with GIS Open source version control tools

Agile, Data, Database, DevOps, General, Opensource, QGIS, Software
It's time to introduce DevOps to your GIS Data management workflow. If your organization manages big volumes of data, commonly referred to as Big Data, your workflows exhibit these common scenarios; Multiuser distributed data editing, frequent check-out and check-in of spatial data, data versions comparison over short time changes, edits conflict resolution, maintenance of the different versions against the production version during the lifecycle of data collection, cleansing, development and production. DevOps is a new term that has grown in the GEO-IT industry and GIS is not sidelined in its applicability. It presents a set of principles that in GIS would elaborate how to apply agility in administration and operation of your organizational data development lifecycle. It expands the va...
STDM Code Sprint: Call for Participation

STDM Code Sprint: Call for Participation

Events, General, News, Opensource, QGIS
Code Sprints (also known as Hackathons) are a proven method to develop contributors community around an open source project. To ensure longevity for an open source project, as a sponsor or project owner you have to build capacity to potential contributors who can then invest the same know-how to improving the system for long term sustainability. It would be for this reason that  the Global Land Tool Network (GLTN) is organizing a code sprint that will bring together geospatial experts to further support the enhancement of the Social Tenure Domain Model (STDM) ecosystem. The Event Scheduled take place from April 24 to 27 at the Regional Centre for Mapping of Resources for Development (RCMRD) in Nairobi, Kenya is organized by Metaspatial (Germany) in close cooperation with UN-Habitat and
Why PostGIS is the love of GISers

Why PostGIS is the love of GISers

Applications, Database, Industry, Opensource, Software
We are living in a changing world. A world that is becoming more modern by day. Every individual is now a sensor, generating a continuous flow of location-encoded data, thanks to this new era of location-aware mobile phones , geocoded Computer IP addresses, GPS devices in our cars and so much to list. It is convincing to say that the location aspect of things is now part of our lives. Seemingly, questions never end. How close is the nearest hotel from my office? Where were the crimes in my city for the last two months? What is the shortest route from my home to the hospital? Where should the next emergency station be built so as to minimize the response time? People ask these questions and others like them, every day all over. Answers to these questions and the likes requires a mechanis...
Land information management database center launched in Mwea

Land information management database center launched in Mwea

Applications, Case Studies, Industry, Opensource, QGIS
Mwea irrigation scheme is well known for its mass rice production in Kenya. It covers an area of land (approx. 30,000 Acres) and is managed by the National Irrigation Board. The board is responsible for  the control and maintenance of utilities in the area including road maintenance, canals clearing, water gates installation, water regulation etc. The management of this scheme has however been based on experience basis and reliance on statistics over the years in the area. Water and other amenities are however vital to the growth of rice in the scheme and each farmer, for example, has to pay for the water prior to a planting season. This allows for the access of this scarce facility in their paddy fields. Records for all land owners, who have paid for their water bills and who owns the pad

The AgriGIS workshop and Think Tank was a resourceful event that was held at RCMRD (host) in conjuction with The University of Nottingham,Global Open Data for Agriculture and Nutrition (GODAN) and  Crops For the Future(CFF) on October 27-28, 2016. Among the delegates were Professionals, Policy Makers, government organizations, NGOs, Private institutions , Journalists (In Agriculture), Life changers and institutions of higher learning from all over the world. The workshop, as the name indicates, focused on the use of Open data, GIS, Remote sensing and Surveying technologies to 'end hunger, achieve food security and improved nutrition and promote sustainable agriculture’ (UN Sustainable Development Goal (SDG2)). Projects from different sectors leveraging these technologies were showcased
