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.
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
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.

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.
You also publish your data on web without using QGIS visit MapOG Tool
Quantum Geographical Information System is a open source platform for viewing, editing, managing and analysis of spatial data with various features which makes your analysis better. As we need word processor to deal with words similar to this for spatial information we require GIS application. In this blog I am providing Introduction of QGIS 3.4.4 for beginners. QGIS 3.2.1 ‘Bonn’ is released on 20 July 2018. QGIS 3.6.2 is the current version but its functionality is same as QGIS 3.4.4. With the help of QGIS you can also create Interactive Web Map.
Main area of QGIS is called as canvas. Likewise other GIS applications toolbars, panels, status bar and menu bar is also. Lets start its study in brief.
1. Menu Bar –
In the above image 1 number is showing main menu bar. You can access almost everything of QGIS from main menu. You can use various features and functions of the QGIS menu style. The Main Menu cannot be moved unlike the toolbars and panels.
2. Toolbar –
Toolbars have buttons that provide a one click access (i.e. shortcuts) to many of the features and functions found in the Main Menu. Toolbars are movable and free floating.
3. Canvas or Map Display Panel –
It shows geographic display of GIS layer or panel layers. It covers maximum area off course because of its function. Create a Basic Map on canvas
4. Browser Panel –
It provides a list of files on your computer. You can drag and drop GIS files into the Layers Panels to view them. This panel is movable and can be hidden/shown on the GUI. We can display it by right click at tool bar and choose the panels you want to use.
5. Layer Panel –
This panel shows map layers that are in your current project. Layers can be turned on/off, clubbed , change drawing order, etc. Extract or Select features in Layer.
6. Status Bar –
It display all the relevant information about the current project. It shows the current scale of the map display, coordinates of the current mouse cursor position,and the coordinate reference system (CRS) of the project.
Now, you get familiar with QGIS interface, how it works, what is the need. Hope this post is beneficial for amateur GIS professional. If you face any problem in downloading QGIS and in using QGIS 3.2.1 desktop drop you comments. Any suggestions are welcome.
Category map in GIS is the most common and simple type of GIS Map. Category map in GIS can be created very easily with the help of MapOG Converter Tool. The Category map in GIS help us visualize and identify the category of the location. Categorization is an essential requirement for the map users to analyze and understand the data easily.
Create Category Map in GIS – IGIS Map Converter Tool
Styling a Category map in GIS allows you to give different features and styles based on values in the attribute data in a specific layer. As a result user can easily analyze and understand the data. Likewise with the help of styling the attribute data in a layer, user can categories specific locations and data in minutes.
To create GIS Category Map with IGIS Map Tool you need to follow some steps as follows:
Upload dataset and create a new map project Or Open your existing map project.
Once the map is open click on the “Style Layer” option on top of the map layer.
Select a layer that you want to create GIS Category map with.
Now click on the Category map section to create GIS Category map.
Create Category Map in GIS – IGIS Map Tool
The column dropdown in the Category section contains every column present in the data attribute table. Select the column that you want to categorize. By default each different value in the column will be given its own color.
Only the first 50 columns will be styled because columns have the limit of not more than 50 unique values. As it can not style more than 50 values.
You can set the opacity for the colors to filled in the fill section. Each category will be assigned a color at random from the color bar and you can also change the default color in the fill section.
You can also set the line width, opacity & color of the stroke or outline section.
Finally this is how you can Create Category Map in GIS with IGIS Map Converter Tool. This type of visualization is useful for classifying expertise and insight into a whole new map on the basis of location or dataset in the attribute table.
Category Map in GIS – Uses
Business analysis, Risk management and classified mapping are the main uses of Category map. It can be very helpful because of the its ability to allow us visualize the category of the data attribute table. It also provides a deeper understanding of the commercial and operational data associated with a particular dataset.
Category Map mainly serves in following industries:
Let’s take a example. US Government took a survey in Florida (USA) for reviewing the unemployed population of different areas to compare the number of unemployed people in one area to the number of people in another area in Florida. By creating Category map they helped in the visual analysis of the unemployed population in different areas of Florida.
Category Map in GIS categorizes the unemployed population in different areas of Florida with the help of MapOG Converter Tool.

Cartography is a science which deals with the study and drawing of maps. Simply, we can say it is related to mapmaking methods. Cartography is made of two words ‘Carto’ means map or chart and graphy means ‘to draw’ or ‘to write’. Here in this article we will understand Basics of Cartography: Map, Map Projection.
Cartography is related to representation while GIS is concerned with the analysis of spatial data. Sometimes, maps becomes more popular than their makers.
What is Map?
A visual depiction of all or part of an area on a flat plane is termed as MAP. Simply, we can say art of representing the surface of sphere or three dimensional into two dimensional body.
Types of Map Projection:
A map projection is the method to represent the spherical surface or object like that in two dimensional plane or flat surface. So therefore, there are both distortion and projection.
There are three major types of Projections:
The name of the projection is the shape that the image is projected onto.
Cylindrical Projection
Conical Projection
Planar Projection
Cylindrical Projection –
It is also known as Mercator Projection. One can imagine that a paper to be wrapped as a cylindrical around the globe, tangent to it along the equator.
In this projection size and shape of land near poles are highly distorted.
Area near the equator is lightly distorted.
Direction provided in this cylindrical map projection is accurate.
Cylindrical Map Projection is important for navigation.
Conical Projection –
In a conic projection area of the Earth is projected on to the cone. Simply we can say when we place a cone on the Earth and unwrap it, then the result of the projection is termed as conic projection. It is tangent to the Earth along a line of latitude.
Planar Projection –
Planar projection also known as azimuthal projection. In this projection a flat sheet of paper is tangent to Earth at one point. Point of contact may be any point on Earth surface; most importantly north and south poles are used for GIS database. Selection of point of contact depends on the reasons why we need projection or what type of function we want to do with the projection.
In this tutorial we are focusing on the Leafletjs basic shapes used for mapping.

Get Band Information from WMS GeoserverLeafletjs. Band Information from Layer: In its simplest form, a raster consists of a matrix of cells (or pixels) organized into rows and columns (grid), where each cell contains a value representing information, such as temperature, precipitation or elevation etc. Rasters are digital aerial photographs, imagery from satellites, digital pictures, or even scanned maps.
Data stored in a raster format represents real-world phenomena – Get Band Information from WMS Geoserver Leafletjs:
Thematic data (also known as discrete) represents features such as land-use or soils data.
Continuous data represents phenomena such as temperature, elevation, or spectral data such as satellite images and aerial photographs.
Pictures include scanned maps or drawings and building photographs.
There are three main ways to display (render) single-band raster datasets:
Using two colors—In a binary image, each cell has a value of 0 or 1 and is often displayed using black and white. This type of display is often used for displaying scanned maps with simple line work, such as parcel maps.
Grayscale—In a gray scale image, each cell has a value from 0 to another number, such as 255 or 65535. These are often used for black-and-white aerial photographs.
Color map—One way to represent colors on an image is with a color map. A set of values is coded to match a defined set of red, green, and blue (RGB) values.
When there are multiple bands, every cell location has more than one value associated with it. With multiple bands, each band usually represents a segment of the electromagnetic spectrum collected by a sensor. Bands can represent any portion of the electromagnetic spectrum, including ranges not visible to the eye, such as the infrared or ultraviolet sections. The term band originated from the reference to the color band on the electromagnetic spectrum.
Get Band Information from WMS Geoserver Leafletjs
This demo shows the raster overlay on map with the help of Leaflet javascript library. The raster contains three bands as Red, Blue and green. Here raster data is in GeoTiff format and is published on Geoserver. This demo is about how one can extract the Bands information from layer. In similar way we can also extract values such as elevation, any natural hazards distortion or changes in data from layers.
Get Band Information from WMS Geoserver Leafletjs
For this demo we have downloaded data from from one of the free data download website. It is a raster data containing three bands as blue, red and green. In this demo we render raster data on map and shown the value of bands using popup.
GeoServer is an open source server for sharing geospatial data in both vector format and raster format. It is designed to host major datasets, which can easily render on maps.
To render this data on map, we need to get the data from GeoServer, which can be done by using leaflet javascript library. In the Leaflet library, we have Leaflet-WMS plugin.
WMS (web map service), is a way of publishing maps. This format is similar to map tiles, but more generic. A WMS image is defined by the coordinates.
L.tileLayer.wms: It provides a simple interface for loading tiles from a WMS service. Here we also need to provide layer name, format of layer and make transparent as true.
In this way we can render raster data and have layer information. This information further can be used for analysis purpose. For example we can have vegetation index (NDVI) from values of bands. We can actually calculate the loss information if having two time series band information.
Here we will find out how to implement GeoServer Tiling to make wms tiles load fast.
Tile Layers from geoserver:
The need of tile layer is to speed up the rendering of data. It is similar to the Layer Preview for GeoWebCache. There are png, jpeg, geotiff many formats available to store the tiles. In all the format png is considered as fastest format to render data with geoserver.
The size of a vector tile is usually smaller than an image tile, resulting in faster data transfer and lower bandwidth usage.
GeoWebCache, embedded with GeoServer efficiently stores the vector tile data. Since styling is done by the client, not the server, GeoWebCache only needs to store one tile for all different styles.
Because the vector data is available on the client, very high-resolution maps can be drawn without corresponding increases in bandwidth.
The client has native access to the actual feature information (attributes and geometry), allowing for very sophisticated rendering.
For each layer, GeoServer has some information such as
1. Type: type of layer i.e. line, point or polygon layer
2.Layer name: name of the layer,
3. Disk quota: The maximum amount of disk space that can be used for this layer,
4. Disk used: The current disk space being used by tiles for this particular layer,
5. Enabled: shows whether tile caching is enabled for this layer,
6. Preview: Similar to Layer Preview, this will generate a simple OpenLayers application populated with tiles from one of the available gridset/image format combinations.
7. Action: It has two option seed/truncate or empty. Whereas seed/truncate option opens the GeoWebCache page for automatically seeding and truncating the tile cache and empty option removes all saved tiles from the cache.
Adding GeoServer Tiles
If you have already published your layer on GeoServer, and want it to be in tiles you can follow the procedure given below.
i.) First of all publish your layer with proper name and style. To know how to publish layer on GeoServer you can visit previous articles based on GeoServer.
ii.) Then go to Tile Layer option under Tile Caching. Then search your published layer in list.
iii.) Now you can open that layer as png or jpeg in preview/openLayer option or before that you can seed the layer. Seed layer is nothing but an option where you can decide the zoom level for the layer and hence number of tiles in layer.
While seeding you need to provide the given requirements mentioned below:
a) Number of threads to use:
Possible values are between 1 and 16.
b) Type of operation:
Sets the operation. There are three possible values: Seed (creates tiles, but does not overwrite existing ones), Reseed (like Seed, but overwrites existing tiles) and Truncate (deletes all tiles within the given parameters)
c) SRS (Spatial Reference System):
Specifies the projection to use when creating tiles (default values are EPSG:4326 and EPSG:900913)
d) Format:
Sets the image format of the tiles. Can be application/vnd.google-earth.kml+xml (Google Earth KML), image/gif (GIF), image/jpeg (JPEG), image/png (24 bit PNG), and image/png8 (8 bit PNG)
f) Zoom start:
Sets the minimum zoom level. Lower values indicate map views that are more zoomed out. When seeding, GeoWebCache will only create tiles for those zoom levels inclusive of this value and Zoom stop.
g) Zoom stop:
Sets the maximum zoom level. Higher values indicate map views that are more zoomed in. When seeding, GeoWebCache will only create tiles for those zoom levels inclusive of this value and Zoom start.
h) Bounding box:
(optional) Allows seeding to occur over a specified extent, instead of the full extent of the layer. This is useful if your layer contains data over a large area in GeoServer, but the application will only request tiles from a subset of that area. The four boxes correspond to Xmin, Ymin, Xmax, and Ymax.
iv.) After giving all this, you need to submit these details. After that you will be having a list containing Id, Layer, Status, Type, Estimated number of tiles,Tiles completed, Time elapsed, Time remaining and Tasks. In this list you can check the number of tiles whether it is too high or too low. It should be balanced if it is too high the data size would be high if to low then zooming will not be proper. The number of tiles depends upon zoom start and stop. If difference is very high then number of tiles will be more and vice versa, so it is advised to keep the zoom stop level less than 20.
v.) Before open this layer you should reload the configuration then open it as png and jpeg format under openLayer option.
OUTPUT of GeoServer Tiling-
You must notice that png format would open fast than jpeg format.
The images given below has left side Jpeg format and right side png format. So it is clear that tile in png format render faster than jpeg or any other format.
