QGIS2Web – Create Web Maps

Web Mapping  is a service through which the consumers will choose what they want to show on the map. It is a great way to publish your Geographical information system data to their web and make it accessible by the other consumers. web mapping is tightly related to programming and it has a learning curve. GIS … Continue reading “QGIS2Web – Create Web Maps”

QGIS Server – Configuration and Deploying QGIS Project

In our Previous Post QGIS Server – Installation we have talked about the installation process of QGIS Server in Ubuntu and it was easy. In previous post we get the XML file with GetCapabilities working in the browser. In the following sections, we will provide a sample configuration to set up a QGIS Server on … Continue reading “QGIS Server – Configuration and Deploying QGIS Project”

Connection between PostGIS and QGIS

GIS applications are tools that allow users to create interactive queries (user-created searches), analyze spatial information, edit data in maps, and present the results of all these operations. Geographic information science is the science underlying geographic concepts, applications, and systems and What goes beyond a GIS is a spatial data infrastructure, a concept that has … Continue reading “Connection between PostGIS and QGIS”

Split Sub Divide polygon layer using QGIS – Shapefile, kml, GeoJson

Sub divide or split polygon in multiple parts. QGIS is a special spatial tool, which easily operate with GIS data files such as shapefile, kml or geojson. You might find many cases, where you need to split up polygon or diivde polygon in different parts. For instance, lets suppose we have  administrative boundary shapefile of … Continue reading “Split Sub Divide polygon layer using QGIS – Shapefile, kml, GeoJson”

Merge two or more polygons, points or polyline of Shapefile

Merge two or more polygons, points or polyline of Shapefile in QGIS. Do you want to merge features of to combine them into one feature and to maintain its database dbf values along with it. QGIS – Quantum Geographic information system is of the most important for geographers and with the help of this tool I … Continue reading “Merge two or more polygons, points or polyline of Shapefile”

Image Classification in QGIS – Supervised and Unsupervised classification

Image Classification in QGIS: Image classification is one of the most important tasks in image processing and analysis. It is used to analyze land use and land cover classes. With the help of remote sensing we get satellite images such as landsat satellite images. But these images are not enough to analyze, we need to do … Continue reading “Image Classification in QGIS – Supervised and Unsupervised classification”

Georeference a map with the help of another georeferenced map

Here we will see how to georeference a map with the help of another georeferenced map in QGIS (Quantum GIS). Georeference is a process to associate geographic location coordinates to any kind of physical object which is physically present over a Raster image map or to a physical map, with help of other georeferenced data or … Continue reading “Georeference a map with the help of another georeferenced map”

Different ways to convert Shapefile to GeoJSON – Online or Offline or API

Convert Shapefile to GeoJSON. Shapefile, ESRI made a standard vector file format which is largely adopted in the field of GIS by programmers and geographers . While GeoJSON is also an open standard format designed for Web which largely supported with GIS JavaScript API, other programming API and with GIS (Geographic Information System) software tools … Continue reading “Different ways to convert Shapefile to GeoJSON – Online or Offline or API”
