GIS 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.

Generate Voronoi Polygon from the GIS data

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 point to polygon in IGISMap is based on 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. The Voronoi polygon created for each point 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. Here we generate Voronoi polygon from the gis data.

IGISMap is a web-based platform that powers many of the most important GIS applications in the field of geospatial analysis. The uniqueness of IGISMap in the GIS industry is that it’s UI/UX helps users to perform geospatial operations easily. In IGISMap, you can upload your GIS data and perform geospatial analysis.

Merge polygons features online using IGISMap

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.

Upload and view rendered raster images in IGISMap

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.

Administrative GIS data are polygon vector data of administrative boundaries such as national outline boundary, state boundaries, province boundaries, district boundaries, counties, postcode boundaries etc. Most of the data in IGISMap GIS data are from Open Street Maps. Administrative level data are collected from various government websites and other authentic online sources such as US Census Bureau, Humanitarian Data Exchange, Census India etc.

In this article we will Add GIS Data and Proximity Analysis tools of IGISMap to plot the locations of bank in south Indian states, like the following.

Adding data from Add GIS Data tool

For the requirement of mapping bank locations in south India, let us use the point data of bank locations and polygon data of state level boundaries of India from the IGISMap GIS database of India.

When Add GIS Data is opened, select the country from the list. You can search the name in the search box. Here we will select India and the list of GIS data associated with India will be opened

Adding state level GIS data of India

From the list opened, select administrative boundaries state level to preview the data. After confirming the data, click Add Layer icon. This will open the options to Crop Layer and Add Layer.

Based on our requirement, we only need to map the bank locations of south Indian states. Even though there is no official South India or North India division for the Republic of India, cetain states are commonly considered as south Indian states, north Indian, north east Indian states etc based on their geographical position. Kerala, Tamil Nadu, Karnataka, Telungana, Andhra Pradesh and Goa are considered to be south Indian states.

Thus lets use the Crop Layer functionality to select these states from the data we added. For this, select Crop Layer tool and draw a polygon intersecting all the south Indian states, as shown below.

After the polygon is completed, click Add Layer button to publish the polygon GIS map of south Indian states to the map.

Adding GIS data of bank locations in India

So, the GIS data of south Indian state is added from Add GIS Data tool. Now lets hunt for the GIS data of bank locations of India.

Follow the same steps to add another layer in the existing base map. Select the country from the list and search bank in the Search Layer bar to filter the data list. When you see the data bank point, select the data – preview the map – select Add Layer icon.

Use Crop Layer tool to select bank points in the southern part of India and click Add layer to add the selected bank points.

Now we got both GIS data of the administrative boundaries of southern states and location points of bank added in the map.

Proximity Analysis

Cropping the point GIS data by drawing polygon may not filter the data points accurately. Some points outside the area of interest may still remain. Thus let’s make use of Proximity Analysis tool of IGISMap.

Proximity Analysis can be accessed only from a map. Click onfrom Map Tools to get the list of IGISMap tools from which you need to select Proximity Analysis tool.

In the tool, the user needs to select layers for performing proximity analysis. Here we need to click the Two Layer option as we want to select the bank locations within the polygon boundaries of south Indian states.

In Step 2, first select the input layer, which is the layer you want the features selected from – india_banks_points. Then select the mode of spatial intersection – are within and intersect. Here we want all bank locations that are within the south Indian states polygon boundaries. Thus select within as the mode of spatial intersection. In the next box, select the india_administrative_boundaries_state_level from the dropdown.

Click Next. Search Custom Filters step opens next, but we done need any further filter requirements. So click Get Result button and see the resulting points highlighted on the map

Click Publish which will publish the GIS data of bank locations only in the added south Indian states.
