​

Corporate Geo-Informatics (CGIS) switched over to a newer 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 upgrade, several of these cache and cookies need 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.

To assist, we have attached quick help manuals with steps on how to clear your cache for the browsers Google Chrome and Microsoft Edge. The concept is the same for the other internet browsers.

CoJ Spatial data Inventory 2024

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

Corporate Geo-Informatics (CGIS) has successfully acquired the 2023 Aerial Imagery products for internal and external clients. The capturing of the various aerial imagery products, the processing/validation, and quality assurance of these products by the appointed service provider has been concluded and handed over to CGIS.

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


The final products were delivered to CGIS offices from October 2023:


Product one: 15cm Pixel resolution colour Orthophotos, including LIDAR (Light Detection and Ranging) data (minimum 4 points per m²) and 25cm derived contours

This involved the capture, ground control, processing and colour balancing of the orthophotos and LIDAR data. The service provider followed strict guidelines for the quality assurance phase of the imagery. CGIS received 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 assisted 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). The orthophotos were made available on our Online Map Viewers on Jozinet and eServices as of 9 April 2024. The Orthophotos, 25cm derived contours and LIDAR ground and non-ground points  are available on request from our CGIS Projects Section [cgisprojects@joburg.org.za].


Product two: Oblique Imagery

The capture of the Oblique Imagery for the CoJ jurisdiction area was completed and delivered by mid-October 2023. The Oblique imagery was processed [colour adjustments, removal of lens distortions, and exterior optimisations]. Once we have a GIS contract in place, we will look to  publish the Oblique Imagery, via the Online Map Viewers on Jozinet and eServices.
