What is bearing angle and calculate between two Points

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 for navigation or direction.

Online Tool To Calculate Bearing Angle and Distance To Make Route

Bearing is a direction measured from north and it tracks angle in clockwise direction with north line which means north represents zero degree, east is 90 degrees, south is 180 degrees and west is 270 degrees.

Bearing angle at a point with respect to north at P if we measured clockwise then we see in gif is 065 degrees and at Q it is 300 degrees.

What is bearing and calculate angle between two points

A bearing is used to determine direction of one point relative to another point. You can see in  gif given below.

What is bearing and calculate angle between two points

Bearing of two points

Formula to Find Bearing or Heading angle between two points: Latitude Longitude is

β = atan2(X,Y),

For  variable Y = sin(toRadians(lo2-lo1)) *  cos(toRadians(la2))

and variable X = cos(toRadians(la1))*sin(toRadians(la2)) – sin(toRadians(la1))*cos(toRadians(la2))*cos(toRadians(lo2-lo1))

QGIS Tutorial – Quantum GIS Guide

QGIS is one of the most common open source application used by GIS analyst, Geographers, Civil Engineers and many other professionals. If you are new in the field of Geographic Information System (GIS)  you should consider learning this application, as it will help you to solve many complex problems, analyze area, create reports etc. with just few clicks. Let me introduce you what is QGIS and why you should consider using it before providing all the QGIS tutorial links.

What is QGIS and its Advantages:

QGIS is a Desktop based Geographic Information System (GIS) Application for creating maps, editing, viewing and analyzing Geospatial data. Quantum GIS is a cross platform, free and open source application. It can be run on multiple operating system like Mac OS X, Windows, Ubuntu, Linux and Unix.

QGIS has many advantages over other application like:

  • Simple, easy and User friendly Interface(UI).
  • Is of small size and consumes less RAM memory compared to other GIS application.
  • Supports all kinds of GIS file formats – Either vector or Raster.
  • Tons of plugin are already developed for additional functionality which can be used and added directly. If you don’t the plugin you need, then you can
  • Code in Python or c+++ for integrating the one.
  • A free software application under GNU GPL License

QGIS Tutorial – 3D Map view in QGIS 3.4.6

Hi GIS learners here in this series of QGIS Tutorial we learn 3D Map view in QGIS 3.4.6. For 3D view you need DEM – Digital Elevation Model. If DEM alien to you then first understand what is DEM.

What is DEM?

Digital Elevation Model abbreviated as DEM is a 3D view or raster representation of terrain and its is in grid form. Each cell represents a value and each cell or pixel have their single attribute. We can define it as an ordered array of numbers that represent the spatial distribution of terrain attributes. The quality of DEM is a measure of how accurate elevation is at each pixel level and how accurately is the morphology presented.

QGIS Tutorial – 3D Map view in QGIS 3.4.6

For Creating 3D Map you need to Download DEM. After downloading DEM file you need to unzip it. (Extract hgt file) Then in the menu select go to layer >>  add layer >> add raster 

  • Upload the raster file.

Convert Shapefile to DXF

Shapefile is a vector GIS format developed by Esri. It stores geographical information data. Shapefile have three geometries point, line and polygon. GIS data can be stored in different formats and the conversion of data from one format to other is also possible.

So in this post we convert Shapefile to DXF. Before conversion lets know what is DXF ?

What is DXF ?

DXF is a CAD (Computer Aided Design) fil format and it stands for Drawing Interchange Format or Drawing Exchange Format. DXF files make it possible to share drawing data and text-based formats across different CAD applications. DXF files are supported in several 3D applications and are completely open-source, so users can access AutoCAD files without using Autodesk programmes.

Convert Shapefile to DXF

For Shapefile to DXF conversion, go to GIS MapOG Online Convert Shapefile to DXF Tool, after logging in with your registered email and password. If you are a new user, click the Sign Up button in the Login popup and register to GIS MAPOG by filling the details.

There are three main steps for using GIS Converter:

  • Upload the data
  • Choose the format to which it should be converted
  • Download the converted file.

Step one is to upload your Shapefile which you want to convert. You can upload your file from system or select from the Recent Files.

Upload Shapefile
Upload Shapefile

Here we have uploaded the Shapefile of the Texas state of USA.

Step two is to select the output format from the dropdown for the converted file, in this case its DXF. You can also set the Coordinate Reference System of your preference. As a default CRS will set to WGS 84 (World) [EPSG:4326]. Now Click on the Convert File button.

Select DXF as Output Format
Select DXF as Output Format

After a few seconds, your Shapefile will be converted to a Shapefile file and will be available for downloading.

Download and Publish Shapefile
Download and Publish Shapefile

You can also choose to style the layer or continue with further conversion process by clicking the Convert Another File button.

Converted Files section from the dashboard contains the list of the details of all the conversion done in your account, providing both input and output data available for download their corresponding formats.
