Corporate Geo-Informatics (CGIS) recently switched over to our new GeoLIS production environment on Saturday, 28 January 2023.

When you use a browser, like Google Chrome or Microsoft Edge, to access our Online Maps website, the browser saves some information from the website in its cache and cookies. As a result of our recent upgrade, several of these cache and cookies now needs to be replaced. Clearing those fixes problems such as loading or formatting issues on sites – including the blank screen and/or half-loaded map you've been seeing on the Online Maps pages!

To get rid of the challenge, simply clear your internet browser's cache!

Not sure how to do this? For most browsers the option to do so can be found under settings or tools. Some browsers refer to it as “clearing browsing data". Take a minute to check your browser's settings and locate the cached data.

CoJ Spatial data Inventory 2024

Pic.PNG 

 

The Corporate Geo-Informatics directorate, within Development Planning, has compiled the latest Spatial Data Inventory containing all the spatial layers, data-owners, and contact details within the City of Johannesburg (CoJ). Creating and maintaining an inventory of spatial data assists to keep track of data resources available, and can be used for planning and decision-making purposes.

The inventory records:

  • Name and description of the dataset
  • Data type, distribution format, and date created
  • Theowner of the data with contact details
  • Usage limitation of the data

The CoJ Spatial Data Inventory is reviewed annually. The inventory facilitates data sharing as it contains all essential information to enable future re-use, to avoid duplication, and to make data archiving easy.

The Spatial Data Inventory can also be found under the Help --> PDF Help Files section!


Aerial and Oblique Imagery for the City of Johannesburg - 2023

Picture1.png

Picture2.png

Corporate Geo-Informatics (CGIS) is presently busy with the procurement process to acquire the latest aerial imagery products 2022 for internal and external clients. Phase 1 (procurement process) of the project has been successfully completed. We have experienced unforeseen delays out of our control, and a Service Provider(s) was appointed in November 2022. After much deliberation between the user department, CoJ Legal and Contracts, GSSCM and the appointedSservice Provider, the Service Level Agreement for the project was drafted, finalised and signed off by both parties. 

Phase 2 has now commenced and will see the capturing of the various aerial imagery products and the processing / validation and quality assurance of these products by the appointed Service Provider(s). This will be the most time consuming part of Phase 2.

 The aerial products will cover the City of Johannesburg's jurisdiction area (1644km²), including the Driefontein Wastewater Treatment Works, North West of Johannesburg.

 Should the project time-lines stay within the schedule and no unforeseen delays, the following products should be delivered to CGIS offices from mid-2023 onwards:

 Product one15cm Pixel resolution colour Orthophotos, including LIDAR (Light Detection and Ranging) data (minimum 4 points per m²) and 25cm derived contours

This involves the capture, ground control, processing and colour balancing of the orthophotos and LIDAR data. The service provider to follow strict guidelines for the quality assurance phase of the imagery. CGIS should receive the first imagery set for internal quality assurance by mid-June 2023. A trained team of CGIS staff members and staff members from the Municipal Entities will assist with the tedious task of verification and validation of the supplied aerial imagery (381 tiles, 3km by 3km, checking at a scale of 1:500). This time-consuming task should be finally completed by end of July 2023 and made available on the CGIS website by August 2023. The Orthophotos will be available on our online map viewer. The Orthophotos, 25cm derived contours and LIDAR ground and non-ground points will also be available on request from our CGIS Projects Section due to the size of the data.

 Product twoOblique imagery

The capture of the oblique imagery for the CoJ jurisdiction area to be completed by mid-July 2023. The Oblique imagery will then be processed [colour adjustments, removal of lens distortions and exterior optimisations]. Once the testing has successfully been concluded the 2023 Oblique imagery will be accessible via the online map viewers on Jozinet and eServices, hopefully by August 2023.

Product threeOnline Annual Satellite Imagery subscription (new product)

Corporate Geo-Informatics (CGIS) will be acquiring a new imagery product as part of the Aerial 2023 contract. The new product is an annual license subscription for Online Satellite Imagery for the City of Johannesburg jurisdiction area. The imagery will have access to all available image bands and allow for change detection, using various time periods as reference. The satellite images will be made available as true colour, ortho-rectified image strips. Due to budget limitations, resulting in capped imagery downloads [10GB per annum], the focus will be on change detection within informal settlements. Access to the satellite imagery [via Internet Browser, API or GIS application] will be limited to the CGIS Projects Section. This will be an exciting new addition to the CGIS suite of aerial imagery products and will be a very useful product especially in the year two and three of the aerial contract when no new orthophotos are captured.

Map of the Month: Unauthorised occupation of land and informal settlements in the City of Johannesburg

MAP OF THE MONTH-Newest.jpg

Author: Londeka Thanjekwayo

Published: June 2023​​

​Introduction

Unauthorised occupation of land is an ongoing challenge in the City of Johannesburg where many people are faced with limited access to affordable housing because of the immense housing demand as a result of constant in-migration. In a report on Managing and Curbing Unauthorised Land Occupation the Housing Development Agency (2016) defines unauthorised land occupation as when a person undertakes the following:

  • occupies an 'empty' piece of land and erects some form of shelter
  • occupies an existing building, that could either be a derelict building or empty building such as an unoccupied RDP house); or
  • overstays a lease agreement​
​In the context of this piece unauthorised land occupation is characterised by the occupation of land with the intention of erecting a physical structure or establishing a settlement on it. Unauthorised land occupation has been occurring frequently across metropolitan areas and cities throughout the country. Once land is occupied, basic services must be delivered or in certain instances temporary emergency accommodation needs to be provided, placing additional obligations and burden on municipalities as resources need to be diverted to areas that have not been planned for.

There is a relationship that exists between unauthorised land occupation and the proliferation of informal settlements in that the land occupation will often result in the development and growth of informal settlements.
