KML or Keyhole Markup Language is a collection of geospatial data on map and commonly used in Google Earth or google services, while PDF stands for Portable Document Format is used for digital exchange. KML and PDF is a type of vector format of GIS data. Using IGIS Map Tool you can easily convert – KML to … Continue reading “Convert KML to PDF”
KML, or Keyhole Markup Language, is a geospatial data collection used in Google Earth and other Google services. TIFF, also known as Tagged Image File Format, is a file format for transferring, storing, and displaying raster images. This format is commonly used for scanned aerial photography and maps, as well as digital satellite imagery and … Continue reading “KML to GeoTIFF – Vector to Raster Conversion”
A GIS file is a format used as a norm for encoding geographical information into computer readable file. GIS (geographical information system) file is mainly divided or differentiated into two vector format and raster format. Shapefile format is one of the commonly used GIS format developed by ESRI, while PDF stands for Portable Document Format is … Continue reading “Convert Shapefile to PDF”

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 … Continue reading “Shapefile to GeoTIFF – Vector to Raster Conversion”
Hello GIS learner today in this post we are introducing term Map matching is the linking or matching of observed raw GPS signals shown in below image with green color points with the road segments which the GPS signals actually corresponds. The coordinates of GPS observations are close to the road map but not exactly … Continue reading “Map Matching”
In Telecommunication ‘tele’ comes from Greek means far off and ‘communication’ means exchange of information using some medium. Location information is elemental for telecommunication and GIS in Telecom is widely accepted. Geographical Information System tools manages and analyzes the location of dp junction, available ports, fiber cables lines on the map that increases efficiency of the system. Locate DP … Continue reading “Locate DP Junctions, Ports, Fiber Cables, Connected Houses – GIS Telecom”
Unsupervised classification is based on software analysis. It uses computer techniques for determining the pixels which are related and sort them into classes. In this post we doing unsupervised classification using KMeansClassification in QGIS. For supervised classification check earlier articles. For Beginners check – QGIS Tutorial Unsupervised classification using KMeansClassification in QGIS Add a raster … Continue reading “QGIS Tutorial: Unsupervised classification using KMeansClassification”
Projection is a method to represent 3D data into 2D. It plays a important role in GIS. A map projection is termed as Coordinate Reference System (CRS) and QGIS allows users to define custom CRS. So in this article QGIS Tutorial – Vector Analysis – Create New Projection we will get familiar with creating your own CRS … Continue reading “QGIS Tutorial – Vector Analysis – Create New Projection”
In geometry angles are measured regardless of direction or orientation as in trigonometry we measure angle by rotating anti clockwise. Here x-axis is (0) zero degree and y-axis is at 90 degree. So in this article we get familiar with What is bearing and calculate angle between two points. In GIS bearing angle is used … Continue reading “What is bearing angle and calculate between two Points”
