GIS and Open Source – Introduction to QGIS (ID:QGIS22/001)
* Webinar starts at minute 10:02
Date:
15 NOVEMBER 2022
Description:
“Opensource is computer software that is released under a license in which the copyright holder grants users the rights to use, study, change, and distribute the software and its source code to anyone and for any purpose”, please check out the following link for the full text https://en.wikipedia.org/wiki/Open-source_software. But what is the impact for users in our industry? We need to create maps, display them and analyse our data spatially. In this webinar we are going to talk about the overall open-source industry, the pros and cons and what is available for us. We will also talk specifically about QGIS, where to download it and how to install it.

QGIS: Interface, Views and Layers (ID:QGIS22/002)
* Webinar starts at minute 09:03
Date:
29 NOVEMBER 2022
Description:
In this webinar will talk and explain how data are organized. We will explain what is a view, what are layers and specifically how to add them into our map. We will discuss how to create “views” to display geo-graphic data (layers); creating layers from X,Y coordinates; setting a view’s map projection; manipulating the symbology and classifying or data spatially; we will also discuss about the labelling capabilities of QGIS and how to label layers.

QGIS and Tables (ID:QGIS22/003)
* Webinar starts at minute 12:07
Date:
21 DECEMBER 2022
Description:
In this webinar, we will demonstrate how to create a QGIS table from a variety of tabular data sources; selecting data from a table and explaining the Joining and Linking concepts based on multiple tables. We will also explain how to Modify the structure of a table; editing values in a table and lastly how to create a chart for presenting tabular data.

Creating and Editing Layers (ID:QGIS23/004)
* Webinar starts at minute 03:54
Date:
10 JANUARY 2023
Description:
This webinar is a continuation webinar “QGIS22/003”. We will discuss and demonstrate how to create spatial data using QGIS; we will discuss how table structure is created as well as the base geometry. We will also discuss the concepts of adding and editing “features” as well as editing and updating attribute information.

Spatial Query and Analysis (ID:QGIS23/005)
* Webinar starts at minute 08:44
Date:
31 JANUARY 2023
Description:
This webinar covers the importance of using QGIS in analysing data spatially (also we will cover how to generate statistics on data). QGIS comes with powerful selection tools and we will learn how to select data based on feature relation-ships between multiple layers. We will also demonstrate how to merge features based on specific criteria.

Georeferencing with QGIS (ID:QGIS23/006)
* Webinar starts at minute 09:55
Date:
28 FEBRUARY 2023
Description:
In this webinar we will discuss the Georeferencing concepts, what is it used for and we will demonstrate a simple example of georeferencing images (rasters). Referencing rasters has always been one of the critical tasks on a GIS platform. We will use QGIS georeferencing tools in order to place the images into their right geospatial location. We will also discuss the concepts of Projections.

QGIS Print Layouts (ID:QGIS23/007)
* Webinar starts at minute 00:30
Date:
07 March 2023
Description:
In this webinar we will discuss about layouts and what is the use of the layouts. We will explain how to create a final map for presentation and printing by combining views, tables, charts, images, north arrows, logos, and scale bars to create a final map.
Adjusting Vectors with QGIS (ID:QGIS23/008)
* Webinar starts at minute 09:51
Date:
21 March 2023
Description:
In this webinar, we will explain how adjusting vectors can be done through different ways which include shifting rotating and scaling data. We will also show how the operations can be carried out using the Affine transformation tools.
Q&A
Question:
How to separate feature based on unique values?
Answer:
1. Click on drop down Vector menu >> Select Data Management Tools >> Choose Split Vector layer.
2. Next, from Split Vector Layer window, select Input file and check the “Add Field prefix to file name”.
3. Select the Output file type.
4. Lastly, specify the output directory to save the output layers.
5. Click Run button to execute the process.
6. Once the process completes, you will have a set of new files.
Partial Data Viewing and Specific Data Export QGIS (ID:QGIS23/009)
* Webinar starts at minute 03:44
Date:
22 AUGUST 2023
Description:
QGIS provide powerful tools that allow you to remove data from the view without deleting them. In this webinar, we will discuss the various methods to view only specific data based on attributes and export only data we need for future use.
