Professional GIS Interview Questions & Answers:

GIS application is a tool that allows users to create user-created searches, integrate and analyze spatial information and present the results of all these operations.

GIS describes any information system that integrates, edits, analyzes, shares, and displays geographic information. GIS technologies are using digital information, for which various digitized data creation methods are used. What is GIS? What is the difference between geo-coding and geo-referencing? Geo-coding is when you associate a place name or an address with map coordinates. Geo-referencing is the process of associating plain digital images taken from a satellite or a plane with map coordinates so that they can be overlaid on street maps.

Name the two data structures that have the capacity to hold spatial data. The two data structures that can hold spatial data include raster and vector. Differentiate between GIS commands and tools? Commands do not require interaction with the map, they just rely on surface. Tools on the other hand require interaction with the map canvas. Name applications of the Arc GIS desktop. Arc Map, Arc catalog and Arc toolbox. Define remote sensing? Remote sensing refers to detection and classification of objects on or in earth without physical contact, generally attained through aerial sensors.

Competent decisions can only be rendered by reliable data and though GIS is an amazing data management tool, using it with GPS helps in validating the data analysis and results. What is a globe? A sphere shaped model of the Earth. What are the 7 large land massses found on a globe called? Name the 7 continents. Where you are,How the size of the map relates to the size of a real place and direction as North,east,south,west.

What does the legend or map key tell? What is GPS? Global Positioning System GPS is a space based satellite navigation system that provides location and time information in all the weather conditions, anywhere on or near the earth. List the satellite navigation systems? The navigation systems are as follows:. Explain briefly the working principle of GPS? These distances and satellite location are used to compute the location of the receiver using the Navigation Equations. Although 4 satellites are required for normal operation, fewer apply in special cases.

Explain the structure of GPS? The structure of GPS have three main segments. These are as follows: Page segment, Control segment and User segment. Explain the space segment of GPS? Space segment is composed of 24 to 32 satellites in medium Earth orbit and also includes the payload adapter to the boosters required to launch them into orbit. Explain the control segment of GPS? Control segment is composed of a master control station , an alternate master control station, and a host of dedicated and shared ground antennas and monitor stations.

Explain the user segment of GPS? User segment is composed of thousands of U. What Is Gps Rollover? Effective as of Midnight 01 May , Selective Availability has been set to zero. Explain Portable Gps? Although any small global positioning system could be referred to as a portable GPS, the term generally refers to those units which give driving directions and are meant to be mounted in cars.

Others, used for outdoor activities, are generally referred to as handheld GPS units. What is a project. You can think of a project file as a database management tool.

GIS users often must work on the same files for long periods of time, and the. What is a shapefile? Shapefiles are computer files that produce images for users in a GIS environment. There are three basic types of shapefiles: line poin and polygon. If you have data with spatial locators e. Furthermore, you can join tables in a GIS project. ArcToolbox is the application in ArcGIS that contains data management and conversion tools and wizards e. What are some of the functions of the Spatial Analyst extension?

This is useful for analyzing raster data as well as feature data. What are some of the functions of the Geostatistical Analyst extension? Is there any way to change or expand existing ArcGIS functionality? Scripts work with the existing software to extend functionality or to automate common tasks. How do you edit a project. Why do you need to edit a project file? Once you open your project file, editing is simple.

The last saved version of your files will appear on your computer screen, and you can manipulate the existing settings to update the file. Always remember to save it! Project files must be edited in order for changes to be reflected in your work.

You often work on GIS projects over long periods of time, and as you work, new data, shapefiles, etc. What is the MSD file and can I edit it? How does GPS device work? What is Selective Availability SA? The net result of SA was about a five-fold increase in positioning error.

DOD achieved signal degradation by altering also known as dithering the satellite clock. Why was SA Necessary? SA was used to protect the security interests of the U. Will SA ever be turned back on? It is not the intent of the U. To ensure that potential adversaries to do not use GPS, the military is dedicated to the development and deployment of regional denial capabilities in lieu of global degradation through SA. What kind of orbits are the GPS satellites in? The GPS satellites operate in circular 10,nm 20,km hour orbits at an inclination of 55 degrees.

They are not in geo-stationary orbit. How vulnerable are GPS satellites to jamming and interference? GPS satellite signals, like any other navigation signals, are subject to some form of interference. The FAA is actively working with the U. Department of Defense and other U. Government Agencies to detect and mitigate these effects and make sure that the GPS and any related augmentation systems are available for safe aviation operations. As with all navigation aids, interference, whether intentional or unintentional, is always a concern.

Is the basic GPS signal sufficient to meet all the needs of civil aviation? The answer is that it depends on the service requirements of each user or aviation authority. For many countries, GPS supplies a better capability than the existing ground-based systems or lack thereof. Yet for other countries with large infrastructures, the GPS signal does not meet the accuracy, integrity, availability, and continuity requirements critical to safety of flight.

In the basic form of DGPS, the position of a reference receiver at a monitoring or reference station is surveyed in, that is, its position is known accurately. The user receiver should be no more than about miles away from the reference receiver which makes pseudorange measurements, just as any user receiver would. For each satellite in view of the reference receiver, these biases are computed by differencing the pseudorange measurement and the satellite-to-reference receiver geometric range.

These biases incurred in the pseudorange measurement process include errors arising from ionospheric delay, tropospheric delay, and satellite clock offset from GPS time. For real-time applications, the reference station transmits these biases, called differential corrections, to all users in the coverage area of the reference station.

Users incorporate these corrections to improve the accuracy of their position solution. Will the GPS tracking system make the fleet management easier? Fleet management involves managing vehicles and personnel available.

What are the gains of implementing student GPS tracking system? Is it truly worth the cost and effort? Does it provide what it promises to offer?

 С какой целью. - Танкадо мог посылать фиктивные сообщения на неиспользованный адрес в надежде, что мы его обнаружим и решим, что он обеспечил себе защиту. В таком случае ему не нужно будет передавать пароль кому-то. Возможно, он работал в одиночку.

То, что началось как в высшей степени патриотическая миссия, самым неожиданным образом вышло из-под контроля. Коммандер был вынужден принимать невероятные решения, совершать чудовищные поступки, на которые, как ему казалось раньше, не был способен. Это единственное решение.

Надо идти за ними, думал. Они знают, как отсюда выбраться. На перекрестке он свернул вправо, улица стала пошире.

ГЛАВА 23 Сьюзан, сидя в одиночестве в уютном помещении Третьего узла, пила травяной чай с лимоном и ждала результатов запуска Следопыта. Как старшему криптографу ей полагался терминал с самым лучшим обзором. Он был установлен на задней стороне компьютерного кольца и обращен в сторону шифровалки. Со своего места Сьюзан могла видеть всю комнату, а также сквозь стекло одностороннего обзора ТРАНСТЕКСТ, возвышавшийся в самом центре шифровалки. Сьюзан посмотрела на часы.

На своем Скайпейджере он установил режим вибрации без звонка, значит, кто-то прислал коммандеру сообщение. Шестью этажами ниже Стратмор стоял возле рубильника. В служебных помещениях ТРАНСТЕКСТА было черно как глубокой ночью. Минуту он наслаждался полной темнотой.


Сьюзан еще раз перечитала послание Танкадо. Главная разница между элементами… разница между… нужно найти число… - Подождите! - сказала .

 У нас вирус. Затем раздался крик: - Нужно немедленно вызвать Джаббу. Послышались другие звуки, похожие на шум борьбы. ГЛАВА 55 - Ты уселся на мое место, осел.

И в тот же миг ей открылась ужасающая правда: Грег Хейл вовсе не заперт внизу - он здесь, в Третьем узле. Он успел выскользнуть до того, как Стратмор захлопнул крышку люка, и ему хватило сил самому открыть двери. Сьюзан приходилось слышать, что сильный страх парализует тело, - теперь она в этом убедилась. Ее мозг мгновенно осознал происходящее, и она, вновь обретя способность двигаться, попятилась назад в темноте с одной только мыслью - бежать. И сразу же услышала треск.

Это все равно что изучать иностранный язык. Сначала текст воспринимается как полная бессмыслица, но по мере постижения законов построения его структуры начинает появляться смысл. Беккер понимающе кивнул, но ему хотелось знать. Используя вместо классной доски салфетки ресторана Мерлутти или концертные программы, Сьюзан дала этому популярному и очень привлекательному преподавателю первые уроки криптографии.
