## Change projection of a georeference file in other projection – Reprojection in QGIS

Reprojection in QGIS – Change projection of a georeference file in other projection. Earth is not a complete sphere; it is referred to as spheroid. Generally QGIS use by default Latitude and longitude (WGS 84) coordinate reference system which gives measurement in degrees. Projection is a very vast topic but we will discuss some basic concept of projection and see on the fly projection in QGIS and re-project a georeference file in other projection.

Look over other QGIS tutorial list.

When we want to calculate distance or area over a surface of earth we will get result in degrees when CRS lat lon in degree. We cannot change degree to meters directly as it changes for different places with reference to Earth as it is not in perfect shape. To make this calculation easier, we need to transform this coordinate system to get unit of measurement in meters. Here comes a word projection which is a method by which curved surface of the Earth is portrayed as flat surface.

## Change projection of a georeference file in other projection – Reprojection in QGIS:

Lets start by reprojecting Geographic Reference System(WGS-84) to projected reference system(UTM). It will work for both raster and vector data.

We are taking a georeferenced Image in WGS84 map as an example. Here are the steps to change projection or reproject in QGIS:

1.) Import the data in QGIS.

2.) Right click on the layer and click save as:

3.) Click browse and save your map with a different name. You can use a naming convention as Map-name_projection.

4.) Now click and select the desired CRS.

5.) Search for desired UTM zone of the your map, here I have a map of zone 43 N. Select it and click OK.

• Note: We are converting the file to UTM zone. The Universal Transverse Mercator (UTM) conformal projection uses a 2-dimensional Cartesian coordinate system to give locations on the surface of the Earth. It has divided Earth in 60 zones.

6.) Check add saved file to map. Click ok button.

7.) You will see a projected map in layers but you won’t see the geographical map in the area as if on the fly projection is not enabled by default.

8.) Right click on the projected map layer and click zoom to layer.

9.) Now you will see your projected map. Notice the coordinates in the bottom.

10.) If you want to see both maps. Go to project properties.

11. ) Enable on the fly projection and select WGS84 and click ok. You will see both maps overlapping each other.

### Enable On the fly projection

You can enable on the fly projection by default also so that if two maps have different CRS you will be able to see both maps by following the steps given:

1.) Go to options.

2.) Select Automatically enable ‘on the fly reprojection if layers have different CRS.

Hope, you are now able to convert and change the projection of already georefernced file. If you find any problem in performing steps or if you think there is any steps you want to add on to this tutorial. then do comment below in the section provided, so that we may discuss over it. Also we would like to get your views on how you Change projection of a georeference file in other projection.

## Find or Search Nearby Restaurants, shops, malls or any places in New Google maps

Find or Search Nearby Restaurants, shops, malls or any places in New Google maps. After the introduction of New Google Map and Google Lite mode Map many users are facing problems in using all features in new map, which they can easily use from old Google Classic Map as they are already used to with it. One of the important feature is Near By, which let you search Near-By hotels, Restaurants, Malls, parking places, nearby bus stops or near by Gas Stations from your current location or from any location you want.

## Steps to Find or Search Nearby Restaurants, Shops, hotels, Malls, Parking area or Any places in Google New Maps:

1.) Open New Google Map. If you are using Google Lite mode, switch back to Google New Maps, as Lite mode does not support Nearby Search Feature.

2.) Type in current location or the location name from where you need nearby location result, in Search Box.  And press Enter to Get the result.

3.) Now click on Search box once. This will show you Search Nearby link as indicated below.

4.) Type in the category of places, you want to search. For example “Coffee Shop, or Hotels or restaurant or car parks etc.” And hit Enter. This will list out all Nearby Category result. Here are the list of result information you may get:

• Name of the Shops or location.
• Ratings provided by user.
• Distance from your current location.
• Cost (if applicable)
• Actual Address (You may get the direction by clicking on item)

5.) Red icons Show near by result on the map , while your original location appears as a gray icon.

### Alternate and Direct method to search for nearby places:

In Google Map, ‘near’ is the keyword which you may use to get nearby searches. For Example:

• “restaurants near national mall” to get the nearby restaurants near national mall.

Similariy to find out traffic, you need to enter, “traffic” as keyword to get the real time traffic. You may also be interested to explore other feature of Google Map like, Measure straight line distance, or trace out your all lcoation history or plan your route with public transit and many more.

Hope can now easily search the nearby location easily. I suppose, New Google Map is also good one which provided an easy way to search nearby location and many more options. Use New Google Map frequently to explore new features. Do comment below if you are facing problem in searching nearby location or if you want to give your opinion or suggestion.

## Google Map Route Planner – Find live public transit and Estimated time travel

Google Map Route Planner – Find live public transit and Estimated time travel. Google launched public transport Trip planner providing real time transit update for more than 800 cities world wide, for public welfare as a free service. This feature will help you know the next bus estimated time of arrival at your source, estimated time to travel from one location to another, answers which bus or train or any public transport vehicle you need to take and most importantly give you direction and guidance with live update. Surely Google Maps is one of the most used Maps Engine, where you can Measure Straight Distance, create your own map, find live traffic, know your location history and many more. But Route planner is one of the best feature I have ever used while travelling at unknown places via public transportation. With this feature you don’t need to wait at bus or metro stop, looking for next vehicle as you receive the live Estimated time of Arrival information of next Public transit vehicle.

Google get this data from the different public transit service provider across the world. Google have created the General Transit Feed Specification where transportation agency provider uploads the required data, for easily exchange of transit information. If you are one of the transportation service provider for public and operates with fixed schedules and routes, then you may Join transit partner program from here for free.

## How to effectively use Google map Route Planner of Trip planner feature via public transportation:

1.) Open up Google Map either in Lite Mode or in Full controlled New Google Map.
2.) Click on Direction arrow, which you may find on the text box located at top right.

3.) Now Enter the Source and Destination address location.
4.) Click on Train or Bus type of icon, which signifies Public transit and press Search.
5.) Wow! you will get all possible result to travel from Place A (Source) to Place B(Destination), with next ETA (Estimated Time of Arrival) of vehicle at Stop A, Estimated travel time (ETT), path and Total fare (Fare is not mentioned in every path).

### Route Planner Google Map Experiment:

Let us look at result, when i experimented when searching for Source as Saket Metro Station, DDA flats(A) to Destination as Laxmi Nagar Metro Station(B) in New Delhi(Capital of India). Result shows 4 different path to travel from A to B. When I clicked on Detail of one of the path, a very detailed and appropriate result is shown, which provides the  following details:

• Walking distance and estimated time to reach to a Metro Station.
• Take Yellow line Metro, with heading or direction is described.
• Estimated time of arrival of next metro at your stop.
• Station where i need to switch to different Metro.
• Total estimated time of travel.
• Public Transit Service provider, and its contact number.

When you search for the route, you may get ETA, ETT, Fare and Path for the Current Time. If you want to plan a trip for scheduled time, then you click on Schedule Explorer. Now you can choose the choose the journey start time by dragging the timeline, and explore the results. Here is how schedule explorer looks like:

• Note: For some areas, you may also get the estimated fare charges to travel from Source to Destination.

### Conclusion – Google Map Route Planner:

When i tested the Google Transit Trip planner feature and travel the path, with no surprise the result was very appropriate as Google used the transit data and implemented an intellectual algorithm on it. Estimated time of arrival (ETA) of Metro, Estimated time to travel(ETT) and the most important the correct path or guidance described.

Result:  Application Estimated Travel time = 1 hour 16 Minutes.
Actual Estimate Travel Time = 1 hour 19 Minutes.

#### You may also be interested to see following Google Map Post:

Isn’t that wonderful, the result was very close. Even if you depends on Public transit to travel, with the help of Google Map Public Transit Route planner feature, you are able to schedule your own route and most certainly avoiding the waiting time at stops as now you know the estimated time of arrival of next public vehicle. I loved this feature of Google Map. Have you tried this feature of Google Map? What was the result? Do you know any alternative to this feature? Share your thoughts by commenting below.

## Switch to Google Map Lite Mode (Replace classic map) – Improved Speed

Switch to Google Map Lite Mode. Google map Lite mode is introduced after dropping the old classic map support and as an alternative to it,  with more improved features which also helps in reducing the loading time to render graphics on old browsers.

Many people switch back to old classic map, after the launch of New Google Map in 2013, due to slow processing and rendering of graphics. While you can count Google Maps Lite mode as an best alternative solution to old classic Google Map, as Lite mode would load faster in every browser, which does not support for 3D Earth view feature and other 2D imagery. New Google Map uses WebGL for improving graphics which is not in case with Lite Mode Map.

According to Google “This update provides a number of benefits, including easier trip planning, more accurate traffic data, easier ways to explore new areas, and the ability to get you where you’re going with better search, directions, Street View imagery and more.”

## Switch to Google Map Lite Mode – Listed features:

2. ) Supported in older browsers too.
3. ) Can able to Switch to Satellite mode.
4. ) View live traffic and predictable traffic.
5. ) View direction and ways to get route via bicycle, public transit or by car.
6. ) View terrain.
7. ) Get the current screen view link for sharing.
8. ) Get full menu via one click.
9. ) Dive into street view directly.

### List of features you can’t be able to use in Lite mode Google maps:

1.) 3D imagery and earth view
2.) Your current location on map
3.) Setting your home and work places
4.) Nearby, scaling the distance or getting coordinates features not supported.
5.) Embedding a map and viewing my maps in Google maps.
6.) Draggable route
7.) Reporting a map data problem in Google maps.

If you are in Lite mode, you’ll see a lightning bolt icon in the bottom left which on hovers shows a message: “You’re in Lite mode.” While You can click: “Switch back to full Maps” if your browser supports it. Alternatively you can switch to New Google Map with Full support with the below link:

You can still access your saved places, home and work addresses, personal information and all custom map created, after switching to any of the newer version. None of your data will be lost.

Note : Lite mode is introduced in mid April 2015. You would no longer be able to switch back to older classic google map after the complete update of Google Maps to everyone.

## Convert – Degree Minute Seconds to Degree Decimal Minutes to Decimal Degree format – Latitude Longitude

Convert – Degree Minute Seconds to Degree Decimal Minutes to Decimal Degree format. Geographical location information is represented in terms of Latitude and Longitude, where Latitude gives the angular distance of a point from equator to elevation either north or south, and Longitude gives the angular distance of a point east or west of the meridian. This Angular distance values of Lat and Lon is either represented in Degree, Minute, Seconds(dd,mm,ss) number system or Decimal Degree number system. So let us discuss about, how to represent the location with Latitude and Longitude, their value range and how to convert them with the tool.

#### Latitude values Range:

Point on Equator line is calculated as 0° latitude, while North pole as 90°N and South pole as 90°S. Latitude values range in between 0° and 90° in positive
(representing north) and in negative (representing south) values.

#### Longitude values Range:

Prime Meridian or Greenwich meridian is defined as 0° longitude. Longitude values ranges from 0° to 180° east or from 0° to 180° west.

### Latitude and Longitude Representation – Different converted formats:

Generally in three formats, latitude and longitude values are represented. Let us take example of each format, by taking latitude longitude of San Antonio.
1.) Degree Minutes Seconds :
For example: 29° 25′ 26.5152″, -98° 29′ 37.6974″

2.) Degree Decimal Minutes:
For example: 29° 25.441916666667’ , -98° 29.6283’

3.) Decimal Degree:
For example: 29.424032, -98.493805

## Convert – Degree Minute Seconds to Degree Decimal Minutes to Decimal Degree format

Earth equator line is divided in 360 equal parts, each part represents a degree distance, where 1°=111.32 Km. Every Degree is further divided in 60 minutes. This means, 1 minute = 111.32/60 = 1.85 Km, and every minute is divided in 60 seconds. So 1 seconds = 1.85/60 = 0.0309 Km.

### Convert Degree Minute Seconds to Degree Decimal for the Latitude Longitude values:

As 1°=60’=3600”, so we can compute degree decimal by:

d = degree + minute / 60 + seconds/3600

Let us take an example: Compute 29° 25′ 26.5152″, -98° 29′ 37.6974″ to degree decimal:

Latitude to Degree Decimal = d = 29 + 25/60 + 26.5152/3600 = 29.42432
Longitude to Degree Decimal = d = -(98 + 29/60 + 37.6974/3600) = -98.493805

#### Tool to convert lat lon values from degree minute seconds to degree decimal:

LATITUDE :Degree= Minute= Seconds=

LONGITUDE :Degree= Minute= Seconds=

Latitude :

Longitude :

### Convert Degree Minute Seconds to Degree Decimal:

Again, as 1°=60’=3600”, we would compute Degree, Minute and Seconds separately from Degree Decimal.

• Degree = integer part of Decimal degree = int(ddd.dd) = ddd.
• Minute = integer part of ((Decimal degree – Degree computed above) * 60) = int(ddd.dd – ddd) * 60.
• Seconds = (Degree Decimal – degree – Minute/60) * 3600 = (ddd.dd – ddd – m/60)*3600

Let us take an example. Compute 29.424032, -98.493805 to Degree Minute Seconds format:

Degree = int(29.424032) = 29
Minute = int((29.424032 – 29) * 60) = int (25.44192) = 25
Seconds = (29.424032 – 29 – 25/60) * 3600 = 26.5152″

So latitude = 29° 25′ 26.5152”

Similarly computing longitude of -98.493805, we get the degree minute second to -98° 29′ 37.6974.

LATITUDE :
LONGITUDE :

Latitude :

Longitude :

### Convert – Degree Minute Seconds to Degree Decimal Minutes:

Fetch the Seconds number, and divide it by 60, and then add the result with minute,

For example: Convert 29° 25′ 26.5152” to Degree Decimal Minute:

• Here Seconds = 26.5152,
• so dividing it by 60 i.e 26.5152/60 = 0.44.
• Now add this with Minute, we will get 29° 25.44, which is in Degree Decimal Minutes format. If you multiply again 0.44 by 60 you will get again Degree Minute seconds format.

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

Formula to Find Bearing or Heading angle between two points. Bearing or heading angle is used to define navigation generally in the field of aircraft or marine or Vehicle navigation or while working for land surveying. So what’s the heading or bearing? How we can find bearing between the two points on earth, with the formula? Or How we can find the other point, when one point, actual traveled distance and bearing is given? Let us discuss all this points, followed with the example and experiment with the tool for calculating bearing provided in the post.

Bearing can be defined as direction or an angle, between the north-south line of earth or meridian and the line connecting the target and the reference point. While Heading is an angle or direction where you are currently navigating in.  This means to reach a particular destination you need to adjust your heading direction with the bearing. Generally a ‘compass’ is an instrument, which gives you the direction information for navigation. You must refer Haversine distance formula before going through this post.

## Calculating Bearing or Heading angle between two points:

So if you are from GIS field or dealing with GIS application, you should know bearing and how to calculate bearing with formula. Let us look on formula and tool for bearing:

• Let ‘R’ be the radius of Earth,
• L’ be the longitude,
• ‘θ’ be latitude,
• β‘ be Bearing.

Denote point A and B as two different points, where ‘La’ is point A longitude and ‘θa’ is point A latitude, similarly assume for point B. Bearing would be measured from North direction i.e 0° bearing means North, 90° bearing is East, 180° bearing is measured to be South, and 270° to be West.

Note: If bearing is denoted with +ve or –ve initials whose values lies between 0° to 180°, then –ve is denoted for South and West sides.

### Formula to find Bearing, when two different points latitude, longitude is given:

Bearing from point A to B, can be calculated as,

β = atan2(X,Y),

where, X and Y are two quantities and can be calculated as:

X = cos θb * sin ∆L

Y = cos θa * sin θb – sin θa * cos θb * cos ∆L

Lets us take an example to calculate bearing between the two different points with the formula:

• Kansas City: 39.099912, -94.581213
• St Louis: 38.627089, -90.200203

So X and Y can be calculated as,

X =  cos(38.627089) * sin(4.38101)

X  = 0.05967668696

And

Y = cos(39.099912) * sin(38.627089) – sin(39.099912) * cos(38.627089) * cos(4.38101)

Y = 0.77604737571 * 0.62424902378 – 0.6306746155 * 0.78122541965 * 0.99707812506

Y = -0.00681261948

So as, β = atan2(X,Y) = atan2(0.05967668696, -0.00681261948) = 1.684463062558 radians

convert it into degree

β = 96.51°

This means, from Kansas City if we move in 96.51° bearing direction, we will reach St Louis.

You can also check video explanation of bearing angle.

Tool to find bearing angle between two lat lon points:

Check out the following IGISMap tools to work with Bearing Angle

### IGISMap Bearing Angle Tool

### Formula to find a lat lon point, when bearing, distance and another lat lon is given

Let us assume a condition, where you want to find out the where will an Airplane will land up, if you have following details of that Airplane, i.e actual distance it will travel, the bearing and the starting point (lat,lon)?

• Let first point latitude be la1,
• longitude as lo1,
• d be distance,
• R as radius of Earth,
• Ad be the angular distance i.e d/R and
• θ be the bearing,

Here is the formula to find the second point, when first point, bearing and distance is known:

• latitude of second point = la2 =  asin(sin la1 * cos Ad  + cos la1 * sin Ad * cos θ), and
• longitude  of second point = lo2 = lo1 + atan2(sin θ * sin Ad * cos la1 , cos Ad – sin la1 * sin la2)

You may find both the tool on separate page, with Google map working on it: (It will be update in 2 days, please visit us again)

• Tool to Find Bearing, when two points are given
• Tool to find other point, when bearing, distance and one of the point is given.

I hope this article will definitely help you, to find the bearing or heading. You are free to share more data related to bearing or any thing that you uses to calculate bearing and how you use navigation with bearing.

## Turn on or off location history tracking from Mobile or Browser:

Why to turn ON location tracking? There are many apps and web services which uses your location to either share or fetch the relevant data to you, which in turn increase your efficiency in some way. For Ex. “Google Now” Application. ?And Why to turn OFF location tracking? Obviously, privacy concern is the reason, as no body knows ‘how safe the data is’.

Google tracks your location from either mobile devices which are linked to your Google Account or from the browser in which you are logged in with Google Account, where you have enabled setting to track your physical location in Setting of browser.

### Steps to Either turn ON or OFF your location history tracking in different devices and browser:

1.) In Browser:

• In Chrome and Opera – Select setting and under Location tab, select the appropriate option to enable or disable tracking.
• In Mozilla Firefox – Select Tools, and click on options. Now navigate to privacy tab and under tracking select the check box accordingly.
• In Safari – Select setting preferences and then privacy, where you need to select the desired option.

2.) In Mobile Devices:

• Android – Go to Google Setting -> Location -> Location history. And Turn On or Off from the given check box.

• IOS – Open Settings > Privacy > Location Services. Toggle the button to switch on or off your location tracking for different application.

Google also provide a salient feature to predict future and know current traffic, which uses many devices location data, and on which an algorithm may run to output congestion of roads.

## Track and view your history location from Google Map – Track and Export:

1.) Open up your browser and copy paste the following URL : https://maps.google.com/locationhistory.
