In this post we are going to discuss that how can we convert GeoTIFF to AAIGrid data format.
GeoTIFF is a public domain standard which allows georeferencing information to be embedded within a TIFF file. GeoTIFF files also includes map projection, coordinate systems and datums data to establish the exact spatial reference for the file.
AAIGrid or Arc/Info ASCII Grid is supported for read and write access, including reading of georeferencing transform and some projections. The projections support is quite limited. It is normally produced with the Arc/Info ASCIIGRID command.
For GeoTIFF to AAIGrid conversion, go to Converter tool, after logging in with your registered email and password from MAPOG. 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:
Upload the data
Choose the format to which it should be converted
Download the converted file
Step one is to upload the GeoTIFF file which you want to convert. You can upload your file from system or select from the Recent Files.
Upload GeoTIFF
Here we have uploaded the Satellite image of the Mumbai port in GeoTIFF format collected from Google Earth Engine.
Step two is to select the output format from the dropdown for the converted file, in this case its AAIGrid. You can also set the Coordinate Reference System of your preference. As a default CRS will set to WGS 84 (World) [EPSG:4326]. Now Now Click on the Convert File.
Select AAIGrid as Output Format
After clicking the Convert File button, your GeoTIFF file will be converted to AAIGrid file after a few seconds and will be available for downloading in the Converted Files section of the dashboard.
Download AAIGrid File
Raster files are currently not available for processing in IGISMAP, thus the output AAIGrid file cannot be visualized in the map canvas. Instead it will be available for download in the Converted Files section.
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

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.

To create GIS Bubble maps, first of all we must know what GIS Bubble Map is? Bubble Map is all about symbolizing layers to represent quantity, as it mostly works in the same way as quantity map. Bubble map uses range of colored bubbles of different sizes in visualization of data and is also known as a “graduated marker map”. To create GIS Bubble map with IGIS Map Tool, you need to also look over the MapOG Tool.
A bubble map shows circular markers for points, lines, and polygon features of different size. The bubble sizes are based on a selected numerical attribute value from user’s uploaded layer.
To create GIS Bubble 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 Bubble map with.
Now click on the Bubble map section to create GIS Bubble map.
Now you can choose the numerical attribute in column to reference for the size of the marker in class break section and in the parts section.
Columns have the limit of not more than 50 unique values. As it can not style more than 50 values.
You need to set the number of class breaks required for them as it determines the number of bubble size that is going to be rendering.
You have to choose the Radiusminimumsize and maximumsize of the bubble.
Now fill the opacity and the color you want to show in the bubble on map.
You can also set the opacity & color of the stroke or outline section.
This is how you can Create GIS Bubble Map. This type of visualization is useful for identifying trends & patterns on the basis of location and is most often used for business analysis and demographics mapping.
GIS Bubble Map – Uses
The main use of GIS Bubble Map is the visualization of trends and patterns based on location. Above all Business Analysis and Demographic mapping are some of the main reason to create GIS Bubble Map.
For example, A Surveying company is reviewing the types and locations of airports in the middle east to compare the number of passengers board at airports to the findings from a recently completed research project. Bubble map categorizes the airports by number of passengers that boards the flight in a single day. So this visualization can be used to compare the count of each airport boarding status on daily basis.
(#this is a sample data)
Data and Business analysis is the main reason to Create GIS Bubble Map, It can helps in understanding and comparing the data easily.
I hope this may help you in development and Create GIS Bubble map with IGIS Map Tool. If you find any problem in creating one such example do let us know by commenting below.

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.
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.
