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.
Consider that you are working in the urban planning sector. Higher authorities in the sector have decided to develop the surroundings of the bank area. Your senior has assigned you a project to create a buffer so that later the architect can design the area separately.
When you are working with spatial operations and analysis, GIS is the best method to find a solution to any task. A geographic information system (GIS) is a system that creates, manages, analyzes, and maps all types of data.
IGISMap provides you with all the facilities for spatial operations and analysis without any difficulty. It is easy to use, and it saves your time.

In GIS data, a geographic area is represented in a polygon shape. Geospatial features such as administrative boundaries are digitized in the polygon vector model. In some cases, we need to merge the polygon features based on attribute values or location. After merging, input polygons will merge into a single polygon feature assigned with a single row to store attribute values. When the adjacent polygons with common border lines are merged, they combine to form a single polygon. Through merge functionality, we can create any primary-level administrative boundaries like national boundaries from the secondary level divisions like state or district level boundaries. So here in this article, we are providing steps to merge polygons features online in a single layer.
Merging is a common geoprocessing used in GIS projects for two important cases. One is to merge multiple GIS features into single GIS feature within a GIS data itself. Another application is to merge multiple GIS data into single GIS data. In both cases, geometry entity of the input GIS feature or GIS data should be same ie., either point, polyline or polygon.
IGISMap provides Merge Polygons tool to merge multiple polygon features of a polygon GIS data into single polygon feature. IGISMap is a GIS-based web platform, that provides multiple GIS applications that are most important in the field of geospatial analytics. The peculiarity of IGISMAP in the GIS Industry is its user interface which helps the user to perform effortless geospatial operations. Merge Polygons tool is very easy to use and you can merge the required polgons in just two steps.
In this article we will create the national boundary of USA by merging the polygons of state boundaries. Without further due, lets dive into Merge Polygons tool.
After opening Merge Polygons tool, first step is to add or upload polygon GIS data. Here we will choose Upload Data option to upload the data from your personal computer. Then, click on the Browse button to open the browsing box, where you will choose the file from your pc. In this article, we will be uploading a polygon GIS data of USA state level boundaries.
Upload Data
After opening the file, click the Upload button to start the upload process.
When uploading is complete, polygon GIS data of USA state level boundaries will be published in the map. This data will be selected as the input data for carying out the merge operation.

Developing polygon boundaries from GIS points is an important geostatistical process. IGISMap provides a Point to Polygon tool to create polygons from the point of input point GIS data. Conversion of GIS points to polygon in IGISMap is based on the Voronoi theorem. These polygons are called voronoi polygons. In mathematics, a Voronoi diagram is a division of a plane into regions close to each of a particular set of objects. Voronoi polygon represents the area of influence from the input point location such that any position within the polygon is closer to that point than any other point.
IGISMap is a web platformproviding multiple GIS tools that are most important in the field of geospatial analytics. The uniqueness of IGISMap in the GIS industry is that it’s UI/UX that helps users to perform effortless geospatial operations.

Raster data in GIS are pixelated data format or images that are georeferenced. Here each pixel represent a geographic area storing the values of any parameter associated with that area. Parameters represented by raster images are mostly continuous in geography such as precipitation, elevation, temperature, vegetation indices etc. Raster images also represents categorical features such as land use land cover.
The conversion of an object’s geometry, color, texture, lighting, and other attributes into a display image is called the rendering of an image. It is the technique of creating a photorealistic or non-photorealistic image from a 2D or 3D model using a computer program. A geospatial raster is only different from a digital photo in that it is accompanied by spatial information that connects the data to a particular location. A raster image can be visualized in different styles such as categorical, quantitative, paletted, multiband etc. These visualization can be stored and saved, so that to be used in other platforms for image interpretations for remote sensing analysis.
IGISMap Upload Raster File tool can add the rendered raster image in GeoTIFF format. IGISMap is a GIS-based web platform, that provides multiple GIS applications that are most important in the field of geospatial analytics. The peculiarity of IGISMap in the GIS Industry is its UI/UX, which helps the user to perform effortless geospatial operations.
