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. 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.

Let’s see how this can be done.

Uploading the Rendered Raster Image

After opening Upload Raster File tool, Browse your system folder and select the rendered raster file. Then click on the Upload option.

About the rendered raster data

As we said in the introduction, the conversion of an image’s geometry, color, texture, lighting, and other attributes into a display image is called the rendering of an image. When it comes to GIS raster images, the alteration in geometry and style of visualization depends on pixel values.

The image that we have uploaded here is a stacked image of Landsat bands – Green, Red, and Near Infrared. And this stacked image is rendered into the style of False Color Composite, which we have uploaded here.

Raster image visualized

After successfully uploading, the rendered raster image is published on the map, which can be further analyzed through image interpretations.
