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.

Click Point to Polygon to open the tool directly.

Point to polygon

After opening Point to Polygon tool, first step is to add the data using any of the following options:

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

Here we are going to choose the option to Create Points and then convert the point to polygons through voronoi conversion. Thus lets first create and publish point GIS data.

Creating point data

Select Create Points tab which open Add Points section to plot points on the map at the desired locations.

Create Points
Create Points

Points can be plotted through any of the following options that can be used anytime in this section. They are:

  • Add Points
  • Search Address
  • Lat Lon Values

After finish the plotting, click Save and Publish button to publish the point GIS data.

Converting the Point data to Polygon data

After saving the point data, Convert Layer section is appears to carry out the point to polygon process.

Now click Convert button to run the point to polygon process.

Convert GML to KML

GML is used in a geographic information system(GIS) for expressing  geographic features as well as an open interchange format for geographic transactions on the Internet. KML is a file format used to display geographic data in an Earth browser such as Google Earth. KML is an international standard maintained by the Open Geospatial Consortium, Inc. (OGC).

You can convert GML to KML as well as other GIS Data Conversion using IGIS Map tool.

GeoJSON to GeoTIFF – Vector to Raster Conversion

GeoJSON is an open standard geospatial data interchange format that represents simple geographic features and their non spatial attributes. Based on JavaScript Object Notation (JSON), GeoJSON is a format for encoding a variety of geographic data structures

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.

Using IGIS Map Tool you can easily convert – GeoJSON to GeoTIFF. You can also do other GIS Data Conversion using this tool.

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.

GIS Data Conversion

Hey guys, in this post we are going to focus on one of the important topic of GIS world, which is the “DATA CONVERSION”. Data Conversion means converting computer data into another format. With huge amounts of GIS data available for use, it is more cost-efficient and effective to convert the GIS data from one format to another than recreating all of it.

GIS Data Conversion

There are many ways to convert GIS data and the conversion may use special conversion programs. Simply, it may involve complex data exporting or importing procedures. As we  know there are many data file formats used in GIS, this time we will be converting them from one format to another.

To get the list of the various data file formats you can visit our previous posts.

Vector data file formats in GIS and Raster data file formats in GIS.

To make datasets usable together in GIS, it is necessary to convert the both vector and raster geospatial file from one format to another. And for doing the Conversion we already have posts about the data conversion from GeoJSON to Shapefile and KML to shapefile and many more, but they all have a long way to convert the GIS data. The Alternative to that is some free and commercial converter  software or tools available on the web. There are a Lots’s of tools available on the web, but I recommend you to use  IGisMap converter.  IGisMAP Converter is an online tool to convert GIS data from one format to another format.

IGisMap converter provides On-line conversion and transformation of both vector and raster geospatial data.  In this on-line converter tool the uploaded data file is allowed to convert into various GIS data format.

IGisMAP converter can convert bulk amount of data into another format using any coordinates reference systems. And then you can download the converted data or store it into MyMapData.

This all about IGisMap Converter tool hope it will make your spatial study easy. If you face any problem in data conversion then please comment or chat with us.
