GIS Geographic Information System is a system intends to capture, Store, manage, manipulate, analyze the data. GIS system integrate data and convert it into maps. And as we know visuals are more powerful than words so it makes our understanding of data fast.

What is GIS ?

GIS is a tool to acquire geographic data and produce Geographic information. And generally those information are stored in tabular form. GIS can be defined as a “computer information system that can input, store, manipulate, analyze, and display geographically referenced (spatial) data to support decision making processes”.

Simply GIS visualize your data as a map. And these visualization makes the study interesting with interactive maps. It saves the time and make the system decisiveness that is main requirement.

Map Matching

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 on it. So map matching is process taking input as raw GPS data and giving output as the actual position of road network.

Create your Own Customized Map and Share with Your Clients using IGIS Map Tool.

Why we need Map Matching system?

Now what is the need of map matching, why don’t we use raw data as it is. Map matching problems become complex when the raw GPS data travelled a multi lane road network, even manually distinguish is difficult. Map Matching is used in navigation. Now in the below image you can see the GPS signals in blue navigation but the route is different. In this observation any body can confused with these GPS signals on multi lane. Suppose if you are following these points then you get puzzled when many lanes running simultaneously. It’s a preprocessing method in GIS applications.

In Traffic flow Analysis and in directions Map Matching is useful factor. Aligning GPS across route is termed as Map Matching.

Locate DP Junctions, Ports, Fiber Cables, Connected Houses – GIS Telecom

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 Junction, Ports, Fiber Cable, Connected House – GIS Telecom using IGIS Map Tool

Now we will learn how can we use igis map tool in telecom industry. Go to IGIS Map Tool and login with credentials or register with valid email id.

Create a map using ADD MAP button.

Fill the Tittle of the map with description about the map.

Now you will be redirected to the canvas of IGIS Map. Here on the base map you see the plot number.

Now create a DP – distribution Point using point layer. Tap on Point icon shown below.

Fill the Layer Name. Add attributes for name of the distribution point and ports. You can add multiple ports to a junction.

After creating layer go to Add Point in the drop down of layer. Add point in the map. Now create a Polygon layer with attributes. If you are problem in creating layer then check – Create Map layer – Point, Polygon, Line. In the below image we have created multiple junction and houses with fiber cable connections. This type of visualization make your analyzation fast.

You can get information about the connected house to which port by clicking on junction point. Through this you can track the line if any issues occur at end users.

You can either upload fiber line data (shapefile or any GIS format data) or create line layer. And style your map as per desire. In the below image you can see various DP Junction connected to multiple houses. Fiber cables are also created in the image using line layer.

This is all about of locating DP Junctions, Ports, fiber cables and connected houses in GIS Telecommunication. If you are facing problem in execution then please do comment below.

We also provide customized products as per your needs. Contact us at juhi@igismap.com for information.

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.

Try Route Compass Mobile App for calculating bearing angle and distance.

https://play.google.com/store/apps/details?id=com.bearingangle&pli=1

Calculate Bearing angle in Mobile App

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.

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))

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.

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.

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

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.
