== Quick Introduction ==

This User Manual focuses on helping professionals replicate any tasks previously done in the MOHID Graphical User Interface using the QGIS platform.

[https://qgis.org/en/site/index.html QGIS] is a widely used open source Geographic Information System. If you are not familiar with QGIS, you can find the most recent version for your desired work environment on its official [https://qgis.org/en/site/forusers/download.html download section], you can also find more details about the platform by consulting its [https://qgis.org/en/docs/index.html documentation]. The instructions written in this manual will be using the 3.16 LTR version, so keep in mind that some interface elements may be outdated by the time you’re consulting this manual.

== Creating a QGIS Project ==

In order to do whichever task you need in the QGIS environment you’ll need to create a new project or open an already existing one.

You can create a project by opening the '''Project > New''' Menu. Alternatively, to open an already existing project, simply open '''Project > Open''' Menu and choose the one you wish to open.

With a project open, you can now add whichever elements you desire. You can start by opening a simple world map by expanding the ''XYZ Tiles'' group and selecting ''OpenStreetMap'' in the Browser:

<nowiki>[[File:Example.jpg]]</nowiki>

== MOHID Barimetry ==

=== Visualizing points in MOHID’s .xyz format: ===

QGIS can easily display point data represented in the MOHID .xyz format, although it is unable to process the header’s option details.
To visualize points represented in this format you’ll need to add a new “Delimited Text Layer”. You can do this by opening the '''Layer > Add Layer > Delimited Text Layer''' Menu, which will lead you to the following window:

<nowiki>[[File:Example.jpg]]</nowiki>

You’ll need to select the ''Custom delimiters'' option in the '''File Format''' section and check the ''Space'' option.

In the '''Record and Fields Options''' section, select the ''number of header lines to discard'' according to the size of the .xyz file’s option header. Make sure to check the ''Detect field types'' option and uncheck the First record has field names and ''Decimal separator is comma options'', since the latter are not present in the MOHID .xyz format.

Finally, you’ll need to check the ''Point coordinates'' option in the '''Geometry Definition''' section and select ''field_1'', ''field_2'' and ''field_3'' as the x, y and z fields, respectively. Don’t forget to select the Geometry CRS that matches the one specified in the file’s option header.

You’ll now be able to check the table generated by the given data in the '''Sample Data''' section and add additional settings in the '''Layer Settings''' section.
