Online conversion of GIS points to polygon

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 platform providing 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. In IGISMap, you can upload your GIS data or use data from IGISMap collection to perform GIS analysis.

In this article , we will convert a point GIS data to polygon GIS data and publish in the map as follows.

Voronoi Polygons

Let’s look into the steps to use the Point to Polygon tool of IGISMap.

Click the below link to open the Point to Polygon tool directly

Add input point data

After opening the Point to Polygon tool, the first step is to add the required point GIS data. There are multiple options to add the required data, which are:

  • Select
  • Create Points
  • Upload Vector
  • Upload CSV/Excel
  • Add GIS Data
Add GIS Data

Upload the point data

For this article, we will upload the required point GIS data using the Upload Vector option. After selecting the Upload Vector tab, click the Browse button to browse and select the data from the system.

Select the right data and click the Upload button to start uploading the file. In this demonstration, we are going to use the KML file of GIS points representing locations from each state of USA. The name of the file is point USA.

Upload Vector

Input point data will get published in the map after uploading.

Convert Layer

Conversion of GIS points to polygon

Convert Layer section opens when data is added. In this section, input point GIS data will be provided in the name Active Data. Input data can be changed by clicking the Edit icon. Users can zoom into the layer by clicking the lens icon.

Click the Convert button to start the process of converting the input points to polygons.

Convert Layer

A few seconds after clicking the Convert button, polygon GIS data based on the Voronoi polygons will be published on the map. For making polygon maps appealing you can try the style polygon map feature of IGISMap Tool. Voronoi based polygon GIS data will be created

Voronoi Polygon Data Published

Export the data

You can export the data published in a map in any GIS format such as ESRI Shapefile, KML, GeoJSON or CSV and use it for external applications. In the More option beside the layer name, click Export Layer to open the following popup where you can choose the desired format and export the file in your system.

Create point data and convert it into polygons

Voronoi polygon is an area representing the influence from a particular point location. A Voronoi polygon is actually a systematic way to divide spaces into a number of regions using a set of input points. For each point there will be a corresponding area that consists of the locations closer to that point than any other. These areas are called Voronoi cells.

IGISMap provides a Point to Polygon tool to create Voronoi polygons out of point from input point data. IGISMap is a web platform providing multiple GIS applications that are most important in the field of geospatial analytics. In IGISMap, you can upload your GIS data and perform geospatial analysis.

In IGISMap, Point To Polygon tool will convert input point data into polygon data by creating a polygon shape for each point in the input point data, like the following.

Convert KML to TopoJSON

KML or Keyhole Markup Language is a collection of geospatial data on map and commonly used in Google Earth or google services. TIFF (also known as Tagged Image File Format) is a file format for transferring, storing, and displaying raster images. Scanned aerial photography and maps, as well as digital satellite imagery and other geographic data, can be found in this file format.

A TopoJSON file format is a format that encodes topology. TopoJSON is an extension of GeoJSON. This format contains both geospatial data (arcs) and attribute data. In contrast to other GIS formats TopoJSON uses arcs. Arcs are sequences of points, while line strings and polygons are defined as sequences of arcs.

You can convert KML to TopoJSON  file using IGIS Map Tool. You can also use it for other GIS data Conversion.

Shapefile to GeoTIFF – Vector to Raster Conversion

Shapefile is a vector data format for storing geographical data and associated attribute information. It is developed and regulated by ESRI as open specification for data interoperability among ESRI and other GIS software products. Shapefile can be point, line, or polygon features.

TIFF (also known as Tagged Image File Format) is a file format for transferring, storing, and displaying raster images. Scanned aerial photography and maps, as well as digital satellite imagery and other geographic data, can be found in this file format.

GeoTIFF is a public domain metadata standard which allows georeferencing information to be embedded within a TIFF file. The potential additional information includes projections, coordinate systems, ellipsoids, datums, and everything else necessary to establish the exact spatial reference for the file.

Convert Shapefile to TIFF using IGIS MAP Tool. Through this tool you can convert Shp into SQlite, SHP to KML, KML to GeoJSON, KMZ to GPX and many more.

IGISMAP to Convert Shapefile to GeoTIFF
