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

Leaflet Js Plugin Basics Tutorial

In this blog post we are going to provide you the Leaflet Js Plugin Basics Tutorial. Leaflet Js has stated the main aim of its use is to provide JavaScript libraries for drawing maps, with good performance and usability. Leaflet has many features yet to be included for getting excel in performance and usability but the idea being that not everyone is going to use those features, therefore there is no benefit to increasing the size of leaflet and impacting performance. Instead the awesomeness of Leaflet is increased by encouraging third party contributors to craft their own plugins that can leverage the core library capabilities to expand functionality on a feature by feature basis. So, here is the article Leaflet Js Plugin Basics Tutorial.

Leaflet Js Plugin Basics Tutorial

This Leaflet Js Plugin Basics Tutorial contains the basics of using the leaflet plugin and advantages we can have with all of its functionalities. Leaflet Js plugins are the third party plugins which are used to extend the functionality of leaflet map. Now lets just talk about leaflet map and plugins.

Leaflet Js Plugin

There are hundreds of plugins available for Leaflet Js maps. The Leaflet Js plugins provides functionalities in various area of mapping like Tile and image layer, Basemap provider and brass map, Vector file and overlay map extends.

Leaflet Js Plugin Basics Tutorial is all about to show you that anyone can maintain and create Leaflet plugin with deep knowledge and understanding of leaflet and javascript.

You can attach the Leaflet plugin to your map with the help of Github or any other repository via adding the additional .js and .css file into the leaflet html file in the header section. The leaflet plugins really improves the performance and usability of Leaflet Js.

The most amazing thing about leaflet is Its powerful plugin ecosystem. Anyone with some coding skills can create the plugin for leaflet but there are some standards you need to follow before writing the code to create the plugin.

Some of the following standards are as follows:

Leaflet follows pretty much the same conventions except for using smart tabs (hard tabs for indentation, spaces for alignment) and putting a space after the function keyword.
Never expose global variables in your plugin.
If you have a new class, put it directly in the L namespace (L.MyPlugin).
And if you inherit one of the existing classes, make it a sub-property (L.TileLayer.Banana).
Even if you want to add new methods to existing Leaflet classes, you can do it like this: L.Marker.include({myPlugin: …}).
Function, method and property names should be in camelCase.
Class names should be in CapitalizedCamelCase.

Leaflet.draw

Leaflet Js has this amazing plugin which helps in adding the drawing and editing support for markers and vectors overlaid onto leaflet maps. It is one of the main heading under the topic of Leaflet Js Plugin Basics Tutorial. It is a comprehensive plugin that can add polylines, polygons, rectangle, circle, and markers to a map and then edit or delete those objects as desired without using the GeoJSON code.
Leaflet Js has a variety of options for configuring the look and feel of the drawing objects. Leaflet.draw is more used for its ability to enable additional functionality, than an endpoint. It also provides the framework to take those drawn objects and push them to a database.

Leaflet.draw code description

Leaflet.draw is designed to not only be easy for end users to use, but also for developers to integrate. The following is really only suitable for demonstrating that you have it running correctly. Leaflet.draw is very simple to drop into you Leaflet application. The following example will add both the draw and edit tool bars to a map:

<html> 
<head>
<title>new map</title>
<meta charset="utf-8" />
<link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.7/leaflet.css"/>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/leaflet.draw/0.2.3/leaflet.draw.css"/>
</head>
<body>

< div id="map" style="width: 600px; height: 400px;">
< /div >

< script src="http://cdn.leafletjs.com/leaflet-0.7/leaflet.js" >
 < / script > 
< script src="https://cdnjs.cloudflare.com/ajax/libs/leaflet.draw/0.2.3/leaflet.draw.js" > < / script >
< script >
//Creating map and setting zoom
var map = L.map('map').setView([45.8650, -75.2094], 3);

// Set up the OSM layer
mapLink = '<a href="http://openstreetmap.org">OpenStreetMap</a>';
L.tileLayer( 'http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
attribution: '&copy; ' + mapLink + ' Contributors',
maxZoom: 18,
}).addTo(map);

// Initialise the FeatureGroup to store editable layers
var drawnItems = new L.FeatureGroup();
map.addLayer(drawnItems);

// Initialise the draw control and pass it the FeatureGroup of editable layers
var drawControl = new L.Control.Draw({
edit: {
featureGroup: drawnItems
}
});
map.addControl(drawControl);
map.on('draw:created', function (e) {
var type = e.layerType,
layer = e.layer;
if (type === 'marker') {
layer.bindPopup('A popup!');
}
drawnItems.addLayer(layer);
});

< / script >
</body>
</html>

Result:

This code visualize both the draw and edit tool bars to a map:

Now let’s understand the above code in parts, The first part is an additional link to load more CSS code;

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/leaflet.draw/0.2.3/leaflet.draw.css"/>

This loads the file directly from the Leaflet.draw repository. And if you are loading from a local file you will need to adjust the path appropriately.

The second is the block that loads the leaflet.draw.js script.

< script src="https://cdnjs.cloudflare.com/ajax/libs/leaflet.draw/0.2.3/leaflet.draw.js" > < / script >

Leaflet.draw exists as a separate block of JavaScript code and again, here we are loading the file directly from the Leaflet.draw repository.

The last change to the file is the block of code that runs and configures Leaflet.draw.

      // Initialise the FeatureGroup to store editable layers
        var drawnItems = new L.FeatureGroup();
        map.addLayer(drawnItems);
      // Initialise the draw control and pass it the FeatureGroup of editable layers
         
        map.addControl(drawControl);
        map.on('draw:created', function (e) {
            var type = e.layerType,
                layer = e.layer;

       // Shows popup on marker when user’s action triggers

                  if (type === 'marker') {
                    layer.bindPopup('A popup!');
                  }
            drawnItems.addLayer(layer);
        });

layer group to the map called drawnItems. We store elements in this layer.

Then the map.addLayer(drawnItems); line adds the layer with our drawn items to the map.
Next we get to the first of the true Leaflet.draw commands when we initialize the draw control and pass it the feature group of editable layers;

var drawControl = new L.Control.Draw({
edit: {
featureGroup: drawnItems
}
});
map.addControl(drawControl);

For adding the edit toolbar and confirming which (drawnItems) should be editable. These controls are added to the map i.e. map.addControl(drawControl); .

Finally when we add a new vector or marker we need prompt a trigger that captures the type of item we have created (polyline, rectangle etc).

And adds it to the drawn items layer on the map.

map.on('draw:created', function (e) {
var type = e.layerType,
layer = e.layer;
// Show popup on marker when user’s action triggers
if (type === 'marker') {
layer.bindPopup('A popup!');
}
drawnItems.addLayer(layer);
});

In this code part you can store the information that described the element in a database or similar.

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.

Convert CSV to KML

Hello guys, If you are looking for converting your CSV file into KML, you have landed on the right place. Here in this article we are discussing on how to convert CSV to KML in the easiest way possible.

A comma-separated values (CSV) file is a delimited text file that uses a comma to separate values. Each line of the file is a data record. KML or Keyhole Markup Language is a collection of geospatial data on map and commonly used in Google Earth or google services

Using Online MapOG Converter Tool you can easily convert – CSV to KML. You can also do other GIS Data Conversion using this tool.

IGISMAP to Convert CSV to KML

For CSV to KML conversion go to MapOG Converter Tool, after logging in with your registered email and password. If you are a new user, click the Sign Up button in the Login popup and register to IGISMAP by filling the details.

There are three main steps for using GIS Converter:

Click on Tool Converter
Upload the data
Choose the format to which it should be converted

Step one is to upload your CSV file which you want to convert. You can upload the file from your system or select from the Recent Files.

Note:

Input CSV file should have location information in WKT format under a field named as WKT.
Input CSV file should not have any columns with empty column name between other fields.
Well Known Text (WKT) is an Open Geospatial Consortium (OGC) standard that is used to represent spatial data in a textual format.
WKT format represents a geometry with the name of the vector entity ie., POINT, POLYGON or LINESTRING followed by the longitude and latitude of the point feature or the vertex of the polygon in brackets. Example for each entity is given below
- POINT (169.03934 -46.32844)
- POLYGON ((76.61103048 9.85276413,76.612068 9.85303305,76.6124496 9.85362534,76.61269368 9.85513401,76.61374668 9.85455036,76.61466216 9.85409739,76.61630232 9.85377888))

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.
