In the year 2023, creating your own projection for QGIS should be easier than ever. With the latest advancements in GIS software and the ever-growing community of QGIS users, the process of creating custom projections has become much more straightforward. With this tutorial, you can learn how to create your own projection in QGIS in just a few simple steps.
A projection is a mathematical calculation that converts geographic coordinates into a two- or three-dimensional view. For example, a three-dimensional map of the world would require a projection. The type of projection used can affect the accuracy and appearance of the map.
QGIS is a powerful open source GIS software used by many professionals and hobbyists alike. The software allows users to create custom projections based on their own preferences or requirements. Here are the steps to create your own projection in QGIS:
Step 1: Select the Projection
The first step in creating a custom projection in QGIS is to select the type of projection you want to use. This can be done by selecting the “Project Properties” option from the “Project” menu. Once you have opened the “Project Properties” window, select the “Projection” tab, and select the type of projection you want to use from the list of available projections.
Step 2: Define the Projection Parameters
The next step is to define the parameters of the projection. This can be done by entering the parameters into the “Projection Parameters” box. The parameters will vary depending on the type of projection you have chosen, but they typically include the central meridian, the standard parallel, the ellipsoid, and the datum. Once the parameters have been entered, the projection can be saved by clicking the “Save” button.
Step 3: Set the Projection
The third step is to set the projection for the data. This can be done by selecting the “Set Project” option from the “Project” menu. Once the “Set Project” window has been opened, select the custom projection you have just created from the list of available projections, and click the “OK” button.
Step 4: Check the Projection
The fourth step is to check the projection to ensure that it is correctly set. This can be done by selecting the “Check Project” option from the “Project” menu. Once the “Check Project” window has been opened, select the custom projection from the list of available projections, and click the “OK” button. The results of the check will be displayed in the “Check Project” window.
Step 5: Save the Projection
The final step is to save the projection for future use. This can be done by selecting the “Save Project” option from the “Project” menu. Once the “Save Project” window has been opened, select the custom projection from the list of available projections, and click the “OK” button. The custom projection will now be saved and can be used in future QGIS projects.
Summary
Creating your own projection in QGIS is a straightforward process. The steps outlined above should help you create your own custom projection in just a few simple steps. The process is simple and can be completed quickly, so you can begin creating custom projections in QGIS today.
