Satellite Image of Faisalabad

Posted on March 29, 2009 by Administrator

Faisalabad (Punjabi, Urdu: فیصل آباد) is a city in the province of Punjab, Pakistan. It was formerly known as Lyallpur. Faisalabad is the third largest city in Pakistan after Karachi and Lahore. Before the foundation of the city in 1880, the area was very thinly populated. The population has risen from 9,171 in 1901 to 179,000 in 1951 and to 2,009,000 in 1998.^[2] The larger Faisalabad district had a population of about 5.4 million in 1998.^[3]

It is an important industrial centre west of Lahore. The city-district of Faisalabad is bound on the north by the districts of Gujranwala andSheikhupura, on the east by Sahiwal, on the south by Toba Tek Singh and on the west by Jhang. It is 1,135 km (705 mi) from Karachi, 128 km (80 mi) from Lahore, 350 km (220 mi) from Islamabad/Rawalpindi, 187 km (116 mi) from Burewala, and 70 km (43 mi) from Jhang.

The city is at a road and railway junction, which has played an influential role in the development of Faisalabad’s trade and economy. The surrounding countryside, irrigated by the Lower Chenab River, has seen expanded production of cotton, wheat, vegetables, and fruits, which form 25% of Pakistan’s exports. The city is also an industrial centre with major railway repair yards, engineering works, and mills thatprocess sugar, flour, and oil seed. Produce includes super phosphates, cotton and silk textiles, hosiery, dyes, agricultural equipment, andghee (clarified butter). Faisalabad is also the site of the prestigious University of Agriculture, founded in 1909.

Faisalabad is the largest industrial city of Pakistan and its textile capital, specialising in export-oriented manufactured goods.” Source: Wikipedia

District Boundaries of Pakistan

Posted on March 8, 2009 by Administrator

“The Districts of Pakistan are the second order administrative divisions of Pakistan. Districts were the third order of administrative divisions, below provinces and “divisions“, until the reforms of August 2000, when “divisions” were abolished. Districts now form the top tier of a three-tier system of local government with the two lower tiers composed of approximately 400 tehsils and more than six thousand union councils.
Prior to 2001, there were 106 districts but with the reorganisation, these were reduced to 102 by the merger of the five districts of Karachi Central, Karachi East, Karachi South, Karachi West and Malir to form Karachi District. The five districts had formed the division of Karachi which was abolished. The number of districts rose to 106 again in December 2004, when four new districts were created in the province of Sindh of which one (Umerkot) had existed until 2000 and three districts (Kashmore, Qambar and Jamshoro) were newly created.
In May 2005, the Punjab provincial government created a new district^[2] by raising the status of Nankana Sahib from a tehsil of Sheikhpura District to a district in its own right.
In Azad Kashmir, the second tier of government is formed by two administrative divisions (Muzaffarabad) & (Mirpur) with a third tier of eight districts. In the Northern Areas, there are six districts divided between two regions of Gilgit and Baltistan; Baltistan being the part of Ladakh in Pakistani control.” Source: Wikipedia

“Pakistan (Urdu: پاکستان Pākistān), officially the Islamic Republic of Pakistan, is a country located in South Asia and is at a pivotal location at the crossroads of South Asia, the Middle East, and Central Asia. It has a 1,046 kilometre (650 mile) coastline along the Arabian Sea and Gulf of Oman in the south, and is bordered by Afghanistan and Iran in the west, the Republic of Indiain the east and the People’s Republic of China in the far northeast. Tajikistan also lies adjacent to Pakistan but is separated by the narrow Wakhan Corridor. In recent times, Pakistan has been called part of the Greater Middle East.

Pakistan is the sixth most populous country in the world and has the second largest Muslim population in the world after Indonesia. It also has the second largest Shia Muslim population in the world. The country is listed among the Next Eleven economies, is a founding member of the Organisation of the Islamic Conference, South Asian Association for Regional Cooperation, G20 developing nations, Asia Cooperation Dialogue and the Economic Cooperation Organisation. It is also a member of the United Nations,Commonwealth of Nations, World Trade Organisation, Shanghai Cooperation Organisation, G33 developing countries, Group of 77 developing nations, major non-NATO ally of the United States and is a nuclear state.” Source: Wikipedia

We have collected the GIS maps of various administrative divisions of Pakistan in ESRI Shape file format. Here we present the National and Provincial Boundaries Dataset for free. Please refer back if you modify and update them so that more detailed information can be available for other users.

“Pakistan is a federation of four provinces, a capital territory and federally administered tribal areas. The government of Pakistan exercises de facto jurisdiction over the western parts of the disputed Kashmir region,organized as two separate political entities (Azad Kashmir and Northern Areas)

Provinces:

Territories:

Islamabad Capital Territory (IST)
Federally Administered Tribal Areas (FATA)
Azad Jammu and Kashmir (or simply Azad Kashmir)(AJK)
Northern Areas (FANA)

Balochistan and NWFP also have Provincially Administered Tribal Areas.(PATA)

The third tier of government was composed of 26 divisions with two further tiers (districts and tehsils) administered directly from the provincial level. The divisions were abolished in 2001and a new three-tiered system of local government came into effect comprising districts, tehsils and union councils with an elected body at each tier. There are currently 107 districts in Pakistan proper, each with several tehsils and union councils. The tribal areas comprise seven tribal agencies and six small frontier regions detached from neighbouring districts whilst Azad Kashmir comprises seven districts and Northern Areas comprises six districts.” Source: Wikipedia

Using Google Earth for Creating GIS Data

Posted on March 4, 2009 by Administrator

Google earth works extremely well in creating new vector data in the form of points, lines and polygons that can be used as shapefiles in ArcGIS or any other GIS software for more advanced processing.

The biggest advantage is that we don’t need to procure high resolution images at highest costs. Instead we can use Google Earth images as background to create our vector data. Following is few pictorial examples of doing so:

Below is an example of vector map of Sialkot created from the available point, line and polygon features of Google Earth. It includes thousands of streets as line features, places of interest as point features and some special areas as polygonal elements. Below we will explain how we have done that and you will find it is pretty simple.

To add a new road, street, water body or any other linear feature, Add Path button is used which is available in front toolbar as well as in “ADD” Menue (Short key is Ctrl+Shift+T).
A new dialog box will open, here you can specify the name of feature and any other description you want. Some other characteristics can also be specified like color, thinkness and style of the feature. Now drag the dialogue on any side without closing and start digitizing on the image as per your need. While adding vertex, you can use the zoom and pan controls of Google Earth, available on the top right of the window.

Repeat the above process for all the linear features. Each line will be added and can be seen in the left pane under “Places”.

Similar is the case with adding Points and polygons. Below are screen shots:

Examples of adding polygons includes adding parks, stadiums, graveyards, or even housing schemes as a polygonal features. Below are screen shots of that:

Using simple KML to SHAPE convertor tool, the prepared vector data from Google Earth can be used in Arcview / ArcGIS or any other GIS plate form. In the screen shot below, we have used a Shape2KML extension of ArcView 3.2 which let you import lines, polygons or point features from the created kml file.

Here is a view of the above digitized area in Google Earth as well as in ArcView clip_image004

.::Special thanks to Hassan Mughal::.

Hassan Mughal (genius.hassan@gmail.com) has provided the Sialkot map file used in this tutorial in Polish Map Format which was converted in KML and ESRI shape file.
