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.

Nowadays GIS used in every field such as-

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. The potential additional information includes projections, coordinate systems, ellipsoids, datums, and everything else necessary to establish the exact spatial reference for the file.

Convert Shapefile to TIFF using IGIS MAP Tool. Through this tool you can convert Shp into SQlite , SHP to KML, KML to GeoJSON, KMZ to GPX and many more.

IGISMAP to Convert Shapefile to GeoTIFF

For Shapefile to GeoTIFF conversion, go to Converter tool, after logging in with your registered email and password from IGIS. If you are a new user, click the Sign Up button in the Login popup and register to IGISMAP 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.

Converter Tool - Upload Shapefile — Upload Shapefile

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

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

Converter Tool - GeoTIFF as Output Format — Select GeoTIFF as Output Format

After clicking the Convert File button, your GeoJSON file will be converted to GeoTIFF file after a few seconds and will be available for downloading in the Converted Files section of the dashboard.

Raster files are currently not available for processing in IGISMAP, thus the output GeoTIFF file cannot be visualized in the map canvas. Instead it will be available for download in the Converted Files section.

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.

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.

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))
