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.

Step 1 - Change projection of a georeference file in other projection

 

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

Step 2 -Change projection of a georeference file in other projection3.) Click browse and save your map with a different name. You can use a naming convention as Map-name_projection.

 

 

 

 

 

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.

Step 4 -Change projection of a georeference file in other projection
Step 4 -Change projection of a georeference file in other projection

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.

Step 5 -Change projection of a georeference file in other projection

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

Step 6 -Change projection of a georeference file in other projection

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.

Step 7 -Change projection of a georeference file in other projection

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

Step 8 -Change projection of a georeference file in other projection

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.

Step 10 -Change projection of a georeference file in other projection

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

Step 11 -Change projection of a georeference file in other projection

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.

Enable on the fly projection2.) Select Automatically enable ‘on the fly reprojection if layers have different CRS.

Step 2 - Enable on the fly projection

Hope, you are now able to convert and change the projection of already georefernced file.

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.

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.”

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.

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

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

Format of Lat lon - Degree Minute Seconds, Degree Decimal Minutes, Decimal Degree format
Format of Lat lon – Degree Minute Seconds, Degree Decimal Minutes, Decimal Degree format

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.

Tool to convert lat lon values from Degree Decimal to Degree Minute Seconds:


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.

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

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

***Convert θ into radians***

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.

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.
