QGIS 3.2.1- Download/export map in PDF, SVG, Image

In the previous session we learn about creating basic map. Today we throw light on QGIS 3.2.1- Download/export map in PDF, SVG, Image.

Try our tool for creating interactive maps without writing a single code. MapOG Tool

QGIS 3.2.1- Download/export map

First add a vector layer from exercise data (we are using). If want to use data from other sources like Google Map or bing.

Or else download sample data for study-

QGIS allows you to create multiple map from single layer. For creating map layout. Go to project >>>New print layout

Once you choose New Print Layout a dialog box will appear for a tittle.

A new screen will be open for map layout. Add a new map to the layout from left side icon from tool box.

Or, Add item>> Add Map and hold the left mouse button and drag the rectangle. Map will be rendered on the layout.

QGIS 3.2.1 – Adding a tittle

Your map is looking good but without tittle it seems like food without salt. So, lets add some elements in map.

Click on this icon for adding tittle.
Click on the page, move near the map where you want to place tittle. A dummy text will be shown “lorem ipsum” as a default. You can change text by first selecting item and then expand the label tab in layer properties. You can enter text as html also.

You can Resize the label according to your choice.

QGIS – Adding Legend

For making the map more understandable to the readers you can add legend. Go to Add item and tap add legend or by selecting the icon.

And click on the page, where you want to place it.

QGIS – Add a scalebar

Go to Add item and select add scale bar.

Click on the layout where you want to put scale. You can customize it in item properties. (make sure to select the item first)

QGIS – Export Map as SVG, Image and PDF

Try MapOG Tool for creating beautiful map and export map into PDF and Image

When you finally done with all the requirements of map, you can easily export map by buttons provided in the layout toolbar. If you want to print then it also can done with print button.

You can exports as following formats:

Export as Image
Export as SVG
Export as PDF

You can export map as image in PNG, BMP, CUR, TIFF, JPEG etc.

SVG format is best for cartographer because editing of map require for publication. SVG stands for “Scalable Vector Graphic”.

PDF format is easy going for clients so that they get print the pdf if they require.

So, today we learn about the print layout map option in QGIS 3.2.1. If you encounter any problem in doing then comment.

Pin/unpin labels, move labels and diagrams, resize labels of layer using QGIS 3.2.1

In the previous article Layer labeling in QGIS we learn about the basic labeling of layer. Today in this session we touch Pin/unpin labels, move labels and diagrams, resize labels of layer using QGIS 3.2.1

Resize labels of layer

In the map you find find that the labels are not appropriately formatted and either overlap or are too far away from their point markers. You can change label font size in points/mm/pixels.

Go to the Layer styling

You can reach layer styling dialog box by three ways:

Choosing layer icon on label toolbar or by choosing labeling from layer menu and third by right click on layer.

Increase and decrease font size.

Move labels and Diagrams

Choose Move label icon from layer styling panel. Before this make sure toggle editing is activated.

After choosing, you are able to move label or diagram on canvas of QGIS. By this method you can move labels individually. Its quite time consuming if we want to shift or move labels.

For all the labels go to Labels > Placement

You can change the value of distance and click apply.

Change Labels or Rename

Select change label icon from label toolbar

After activating go to the label and drag

Change the label and click on apply.

Print your labelled Map

Pin/unpin Label in Qgis

Pinning means label at its current position. You can choose pin and unpin from icon from label tool bar. You can highlight the pinned label.

View attribute table

You can also create basic map in QGIS 3.2.1

Adding Basemaps from Google or Bing

Add Google Map layer and print them in QGIS 3.2.1 by following steps:

Go to Browser Panel. If you are new to QGIS 3.2.1 then check Add Browser Panel.

Right Click on XYZ tiles, Choose New connection. XYZ tile server provider has a UX enhancements for tiled services.

Enter the name for example: Google Map then copy and paste the URL given below. And tap on OK. Enter the URL of the service which you would like to use, replacing x, y and z parts with curly brackets substitution

URL for adding basemaps from different sources:

For Google Map: https://mt1.google.com/vt/lyrs=r&x={x}&y={y}&z={z}

Google Satellite: https://mt1.google.com/vt/lyrs=s&x={x}&y={y}&z={z}

For Bing aerial: http://ecn.t3.tiles.virtualearth.net/tiles/a{q}.jpeg?g=1

Google Roads: https://mt1.google.com/vt/lyrs=m&x={x}&y={y}&z={z}

In the same way you can add from bing map by putting above URL. Hope this may help you. If you like the post please comment and share. All suggestions are welcome.

Are you newbie QGIS 3.2.1 user check QGIS 3.2.1 for beginners

Selection of Features in QGIS 3.2.1

Add a new vector layer and create a project. In the tutorial we used world continents shapefile. You can do selection by two ways. First option click select feature icon. Choose select features and select the required layer from multiple layer.

Selected screen is shown below.

Second method of selection is for very precise value.

>> Select Features by Expresion. Dialog box of selection by expression will open.

Generate Query in QGIS 3.2.1

Before generating the query you can check attribute table in QGIS. Select the field and values then tap on all uniques and select the desired value. We generated for Australian region “NAME_0” = ‘Australia’

This all about the Select, Save/Export feature as a new layer using QGIS 3.2.1. I tried my best by pictorial explanation. I hope this would help you. Any suggestion or feedback are welcome.

How to do layer labeling in QGIS 3.2.1 – use and change label

Map is not just a picture in GIS, they represent several hidden information of objects. So in the upcoming days we try to understand it more and unearth the hidden data. After creating Basic Map, today we try our hands on layer labeling in QGIS 3.2.1 – use and change label. For extracting more information about the object we do labeling. It makes the layer interactive.

Need Data for study then Download Shapefile of Australia and United States Shapefile

layer labeling in QGIS 3.2.1

Labels are for providing more information about the object. This layer property depends on the attributes of the layer. So, lets start

How to get label dialog box

You can reach Layer Labeling dialog box by 2 ways:

By right click the layer >> Properties>> label (icon shown below)Or, Go to layer menu, select labeling.

Above map is not looking so attractive and informative.

In Labeling Dialog Box, it will show no label.
Click over it and select Single labels
Now come to the Label with (here you need to choose the field from attributes which is to be labeled). In the previous blog you learnt that. View attribute table
Lets select Name_0 from the drop down list.
Customize Font and Size.
Click Apply (live updates are available)

Now the map of continent is label like this.

So, this makes your map more informative. But still above map is not looking so good because off overlapping labels. These label are not placed in centre of object also. Multiple labels are also can be done in QGIS.

Creating a Basic Map – QGIS

QGIS 3.2.1 works well for creating interactive maps, using good set of tools and symbology its become easy to implement. In the previous post we learn how to open and view vector data. So, today we are Creating a Basic Map – QGIS. For creating basic map we work with the vector data. Vector data is very common data format it describes the information in points, lines and polygons.

Creating a Basic Map: Adding vector layer

If you are not familiar with QGIS user interface then check our previous article QGIS 3.2.1 GUI

Open QGIS, we have a new blank map.
Add vector layer by choosing the icon.

In the dialog box, click on the Browse button. And navigate to the exercise data. (before using make sure to download the Exercise data)
Select the appropriate file, let say select road.shp
Here you are, this is your basic map
Save the project.

View attributes

If you are absolute beginners then question comes in your mind what is attributes. No worries when we are here, attributes is a data which store information about spatial data. It gives where, what and why about spatial data in tabular form.

So for roads, the layer we loaded in our basic map we will view its attributes. ->> Click on this icon for opening attribute table or you can use F6 or Go to Layer>> Open attribute table.

->> This attribute table provides more data about road layer, the lines that you see in the map are spatial data. These lines represents the roads.

Current basic map is not so easy to read. We will make it more understandable and interactive using Symbology (use of symbol).

Symbology

In the cartography design, symbology is technique to use symbols to represent graphic features of map. Visual appearance is very much important. Follow the steps for making your map more attractive –

Click two times on layer>> Layer properties dialog box will appear. Select symbology OR right on the layer>> click the layer properties in the menu. Symbology window shown below.

This all the creating a basic map – QGIS. Symbology is useful but the information contained in the layer is still hidden. In the next blog we will learn how to represent this data on map.

Hope it will be useful for GIS professional. Suggestions and feedback are most welcomed.

QGIS 3.4.4 open and view vector data

In GIS , geographic features are often expressed in multiple data formats. Vector and raster data are prime data formats. In this post you will know about QGIS 3.4.4 open and view vector file – shapefile, kml, dxf, geosjon etc. Vector describes geographic data into three types of geometry. Data represented in terms of points, line and polygon.

Use MapOG Tool for creating map

QGIS 3.4.4 open and view vector data

Before using QGIS user interface we can add or remove panel by right click on toolbar. We can also do this in view menu. Enable browser panel and layer panel.

Click the “Add Vector Layer” icon Or use “Layer” menu from the toolbar and navigate to “Add Layer” -> “Add Vector Layer”.

Set the Source Type to “File” and Encoding to “System”.

In most cases system encoding is fine but if you find strange characters in attributes table then you have to change appropriate encoding.

Click “Browse” and navigate to the appropriate files, using the appropriate
file types.
You can select and deselect layer from layer panel. Adjust the layer order by clicking and dragging layers up and down in the “Layers” panel.
You can move by Pan Map icon or you can find Pan Map in view menu

Export your saved map as SVG – Scalable Vector Graphics

Selection of feature for editing

If you want to change any feature then choose Select Feature(s) and move feature to entire feature, where you want to do changes.

To save the project click the “Save” icon and designate a file location. When you re-open a project, any layers that you were using should be in the same
locations on your computer; if they are not, you will need to re-designate the appropriate file paths.

Check out step by step approach in video provided below:

Want to Extract a feature from existing shapefile.

Our goal is to provide new users a working knowledge of QGIS. Although we only had time for a handful of operations, I hope that you now have sufficient familiarity with QGIS to explore it further on your own. If you face any problem in implementing above steps please comment. Any suggestion are welcome.
