Geographic Information System is a system intends to capture, Store, manage, manipulate, analyze the data. GIS system integrate data and convert it into maps. And as we know visuals are more powerful than words so it makes our understanding of data fast.
What is GIS ?
GIS is a tool to acquire geographic data and produce Geographic information. And generally those information are stored in tabular form. GIS can be defined as a “computer information system that can input, store, manipulate, analyze, and display geographically referenced (spatial) data to support decision making processes”.
Simply GIS visualize your data as a map. And these visualization makes the study interesting with interactive maps. It saves the time and make the system decisiveness that is main requirement.

It consists of 50 states, a federal district, five major unincorporated territories, 326 Indian reservations, and some minor possessions. At 3.8 million square miles (9.8 million square kilometers), it is the world’s third- or fourth-largest country by total area. The United States shares significant land borders with Canada to the north and Mexico to the south as well as limited maritime borders with the Bahamas, Cuba, and Russia. With a population of more than 331 million people, it is the third most populous country in the world. The national capital is Washington, D.C., and the most populous city is New York City.
The United States of America is a federal republic consisting of 50 states, a federal district (Washington, D.C., the capital city of the United States), five major territories, and various minor islands. The 48 contiguous states and Washington, D.C., are in North America between Canada and Mexico. Alaska is an exclave in the far northwestern part of North America, connected only to Canada, and Hawaii is an archipelago in the mid-Pacific. Territories of the United States are scattered throughout the Pacific Ocean and the Caribbean Sea.
According to the numerous decisions of the United States Supreme Court, the 50 individual states and the United States as a whole are each sovereign jurisdictions.[4] The states are not administrative divisions of the country; the Tenth Amendment to the United States Constitution allows states to exercise all powers of government not delegated to the federal government.
In the United States, a county is an administrative or political subdivision of a state that consists of a geographic region with specific boundaries and usually some level of governmental authority. Most counties have subdivisions which may include townships, municipalities and unincorporated areas. The number of counties per state ranges from the three counties of Delaware to the 254 counties of Texas. The following is a list of the 3,233 counties and county-equivalents in the 50 states and District of Columbia sorted by U.S. state, plus an additional 100 county-equivalents in the U.S. territories sorted by territory.
Download USA Native American Reservation Lands Shapefile Data
The Indian reservation system was created to keep Native Americans off of lands that European Americans wished to settle. The reservation system allowed indigenous people to govern themselves and to maintain some of their cultural and social traditions. The Dawes Act of 1887 destroyed the reservation system by subdividing tribal lands into individual plots.
Following classes of land reservation are established in USA
Indian Reservation Area
Alaska Native Village Statistical Areas
Hawaiian Home Lands
Oklahoma Tribal Statistical Areas
State Recognized Reservations
State Designated Tribal Statistical Areas
Tribal Designated Statistical Areas
There are 326 Indian Reservations in the United States.[1] Most of the tribal land base in the United States was set aside by the federal government as Native American Reservations. In California, about half of its reservations are called rancherías. In New Mexico, most reservations are called Pueblos. In some western states, notably Nevada, there are Native American areas called Indian colonies.
Alaska Natives previously had many small reserves scattered around Alaska; however, all but one (the Annette Island Reserve of Tsimshian) were repealed with the passage of the Alaska Native Claims Settlement Act in 1971.
There are Hawaiian home land, area held in trust for Native Hawaiians by the state of Hawaii under the Hawaiian Homes Commission Act of 1921.
Oklahoma Tribal Statistical Area is a statistical entity identified and delineated by federally recognized American Indian tribes in Oklahoma as part of the U.S. Census Bureau’s 2010 Census and ongoing American Community Survey.
A state designated American Indian reservation is the land area designated by a state for state-recognized American Indian tribes who lack federal recognition.
A tribal designated statistical area is a statistical entity identified and delineated for the Census Bureau by a federally recognized American Indian tribe that does not currently have a federally established Indian reservation.

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.
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.
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
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
Name of the field ‘WKT’ is not necessary to be case sensitive.
Here we have uploaded the CSV file containing the locations of counties of Washington. It contains locations recorded in WKT format as follows:
Step two is to select choose the output format of the converted file, in this case its KML. You can also set the Coordinate Reference System of your preference. As a default CRS will set to WGS 84 (World) [EPSG:4326]. Click on the Convert File.
Your CSV file will then get converted to KML file after a few seconds and will be available for downloading.
You can also choose to style the layer or continue with further conversion process by clicking the Convert Another File button.
Converted Files section from the dashboard contains the list of the details of all the conversion done in your account, providing both input and output data available for download their corresponding formats.
You can also search locations, add new datasets, edit layers and style the map according to your choice and requirements. As IGIS Map Converter Tool provides many benefits other then just conversion of data. This tool provides us to generate this published map in PDF or as image format.
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
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.
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.
