Geomatics is a relatively new scientific term. It includes the tools and techniques used in land surveying, remote sensing, cartography, geographic information systems (GIS), global navigation satellite systems (GPS, GLONASS, Galileo, Compass) and related forms of earth mapping. Before going through GIS definition and related topics, I want to make you familiar with some other technologies that are commonly used in conjunction with GIS and commonly referred to as GIS-related technologies. Examples include remote sensing, global positioning system (GPS) surveying, mapping and so on.
Lets start with Remote Sensing, one of the most successful GIS-related-technologies:Remote sensing is the technology for collection of information about an object without being in direct physical contact with the object.In the other hand RSallows obtaining data of a process from a location far away fromthe user.Another definition can be : Remote sensing is the process of detection, identiﬁcation, and analysis of objects through the use of sensors located remotely from the object. Digital pictures of the Earth are taken by satellites from 400 to 500 mi above the ground compared with aerial photographs that are taken by aircraft from 1 mi above the ground (for low-altitude photography) to 7 to 8 mi above the ground (for high-altitude photography). Satellite imagery is stored in a pixel (raster) format that makes it ideally suited for incorporation into a GISThus, satellite imagery can be treated as raster-type GIS data. Image processing equipment and methods can be used to extract useful information from hard copy and digital images and combine it with other data layers in a GIS.Remote Sensing SoftwarePreprocessors: These programs help to preprocess raster data for GIS applications.GISExtensions: These programs add image processing capability to a GIS soft-ware. For example, Image Analysis is an extension that adds image processing capability to ArcGIS software

Remote sensing applications have proved to be very useful in forestry and supports foresters with more accurate and cost-effective information and can allow directly to observe a large area or region with a quick turnaround for managing forestfires, foresthealth, and forestconservation.Due to the versatility and scale of remote sensing, it is invaluable in all stages of forest management. Remote sensing is useful in many applications of forestry including terrain analysis, recultivation, updating of existing forest inventories, forest cover type discrimination, the delineation of burned areas, and mapping of cleared areas.
Counting TreesTo monitor production and assess plantation value, (oil palm plantation) managers must know how many trees are on their plantations, which range in size from less than 40 hectares to as much as 75,000 hectares. Currently, workers are deployed to the plantations to count trees manually. The cost of manual counting is low, but accuracy is doubtful. One-meter IKONOS imagery offers an attractive census alternative because individual tree crowns are visible, so trees can be counted accurately. CRISP developed an automated technique for detecting and counting trees in IKONOS images based on differential geometry concepts of edge and curvature. A tree crown�s intensity profile normally assumes a dome shape after some degree of smoothing. The curvatures and edges at various resolution scales are computed and used to locate the trees.
Figure displays delineation of burned areas andthe fire-history map of Catalonia and the frequencies of fire obtained by using one of the employed methods (the more restrictive) during the period 1975-1993. This method discriminated 53.36 % of fires greater or equal than 30 ha , notably more than the 43.60 % of fires detected by the other applied method. The degree of detection improved as the size of fires increased, reaching 78 % for fires of 200 ha. Some preliminary results about characterising fire spatial patterns showed that the 80% of the total area burned in Catalonia comes from small fires.
GPS is a satellite navigation system used to determine ground position (coordinates) a worldwide satellite navigational system formed by 29 satellites orbiting the earth and their corresponding receivers on the earth.
GPS includes29 active satellites located in 6 orbital planes. GPS systems utilize a constellation of satellites orbiting the earth twicedaily(i.e., passing over approximately the same world location every 12 hours) and transmitting precise time and position signals. GPS receiversread signals from orbiting satellites to calculate the exact spot of the receiver on Earth as geographic coordinates (latitude and longitude). The signals from at least four satellites should be available to determine the coordinates of a position. Physical obstructions such as mountains, trees, and buildings, and other factors such as satellite malfunction and rephasing operations can restrict GPS signals and degrade GPS accuracy.
Network fleet™ is the first commercially available aftermarket system that dynamically measures and reports the status of a vehicle's diagnostic performance. Once installed in a vehicle, patented system collects diagnostic data from a host vehicle's on-board computer and location information from a global positioning system (GPS) and transmits these data over a conventional wireless network to an Internet-based computer system. The computer system analyzes the data and posts the results on a secure web site.Surveying : GPS was rapidly adapted for surveying, as it can give a position (Latitude, Longitude and Height) directly, without the need to measure angles and distances between intermediate points. Survey control could now be established almost anywhere and it was only necessary to have a clear view of the sky so the signal from the GPS satellites could be received clearly.Waze : is a GPS-based navigational app which uses turn-by-turn navigation, as well as user-submitted travel times and route details. It was developed as Waze Mobile and now owned by Google. In addition to turn-by-turn voice navigation, real-time traffic, and other location-specific alerts, Waze simultaneously sends anonymous information, including users' speed and location, back to its database to improve the service as a whole.
Mapping usually refers to map-making and often used instead of cartography. Mapping term in fact refers to MAP that is created through some cartographic works (i.e. determining the scale/level of detail and content of geographic or cartographic database, cartographic database and symbol specification for geospatial objects, generalization, layout design etc.). A map is a visual representation of an area – a symbolic depiction highlighting relationships between elements of that space such as objects, regions, and themes. Many maps are statictwo-dimensional, geometrically accurate (or approximately accurate) representations of three-dimensional space, while others are dynamic or interactive, even three-dimensional. Although most commonly used to depict geography, maps may represent any space, real or imagined, without regard to context or scale.Road maps are perhaps the most widely used maps today, and form a subset of navigational maps, which also include aeronautical and nautical charts, railroad network maps, and hiking and bicycling maps. In terms of quantity, the largest number of drawn map sheets is probably made up by local surveys, carried out by municipalities, utilities, tax assessors, emergency services providers, and other local agencies. Many national surveying projects have been carried out by the military, such as the BritishOrdnance Survey (now a civilian government agency internationally renowned for its comprehensively detailed work).

Google Maps is a web mapping service application and technology provided by Google, that powers many map-based services, including the Google Maps website, Google Ride Finder, Google Transit, and maps embedded on third-party websites via the Google Maps API. It offers street maps, a route planner for traveling by foot, car, bike (beta), or with public transportation and a locator for urban businesses in numerous countries around the world. Google Maps satellite images are not updated in real time, but rather they are several months or years old.Google Maps uses a close variant of the Mercator projection, so it cannot show areas around the poles. A related product is Google Earth, a stand-alone program which offers more globe-viewing features, including showing polar areas.* Very primary use of GIS and RS. As a matter of fact, Base maps originally come from Satellite Image (RS) and GIS maps but Google Map service does not support active geospatial layer and tools (MAP+TABULAR DATA+Analysis Tools)
Introduction: Surveying has been an essential element in the development of the human environment since the beginning of recorded history (about 6,000 years ago). Surveying or land surveying is the technique, profession, and science of accurately determining the terrestrial or three-dimensional position of points and the distances and angles between them. These points are usually on the surface of the Earth, and they are often used to establish land maps and boundaries for ownership or governmental purposes.Land surveying can include associated services such as mapping and related dataaccumulation, construction layout surveys, precision measurements of length, angle, elevation, area, and volume, as well as horizontal and vertical control surveys, and the analysis and utilization of land survey data.Surveying Application: It is required in the planning and execution of nearly every form of construction. Its most familiar modern uses are in the fields of transport, building and construction, communications, mapping, and the definition of legal boundaries for land ownership.Example:cadastral : It involves the re-establishment of cadastral surveys and land boundaries based on documents of record and historical evidence, as well as certifying surveys (as required by statute or local ordinance) of subdivision plats/maps, registered land surveys, judicial surveys, and space delineation.
Cadastralis a comprehensive register of the metes-and-boundsreal property of a country. A cadastre commonly includes details of the ownership, the tenure, the precise location (some include GPS coordinates), the dimensions (and area), the cultivations if rural, and the value of individual parcels of land. Cadastres are used by many nations around the world. In addition some cadastral maps show additional details, such as survey district names, unique identifying numbers for parcels, certificate of title numbers, positions of existing structures, section or lot numbers and their respective areas, adjoining and adjacent street names, selected boundary dimensions and references to prior maps. Cadastral surveys document the boundaries of land ownership, by the production of documents, diagrams, sketches, plans,charts, and maps. They were originally used to ensure reliable facts for land valuation and taxation.
Making decisions based on geography is basic to human thinking. Where shall we go, what will it be like, and what shall we do when we get there are applied to the simple event of going to the store or to the major event of launching a bathysphere into the ocean's depths. By understanding geography and people's relationship to location, we can make informed decisions about the way we live on our planet. A geographic information system (GIS) is a technological tool for comprehending geography and making intelligent decisions.
Environmental Systems Research Institute ( ESRI ) ProductsArcGIS, ArcInfo, ArcViewProcedures include how the data will be retrieved, input into the system, stored, managed, transformed, analyzed, and finally presented in a final output. The procedures are the steps taken to answer the question needs to be resolved. The ability of a GIS to perform spatial analysis and answer these questions is what differentiates this type of system from any other information systems.

You know that your GIS (geographic information system) provides maps — that's its basic function and probably the reason you bought it. But a GIS offers more than maps, and the following list includes other outputs:Maps: Everyone recognizes this most common output from a GIS.Cartograms: These special maps that distort geographic features based on their output values rather than their size.Charts: GIS can produce pie charts, histograms (bar charts), line charts, and even pictures in addition to maps.Directions: Another common output, directions show you how to get from one place to another. Customer lists: Business GIS applications often produce customer lists, sometimes with printed mailing labels.3D diagrams and movies: These forms of GIS output help you see the results of your work realistically and dramatically.
- For years, petroleum companies have used GIS to decide where to drill a well, route a pipeline, build a refinery, and reclaim a site.- Today's GIS provides oil and gas industry solutionsthroughout the petroleum life cycle.All major oil companies in the world use GIS technology to manage their location-based information, from leases, wells, and pipelines to environmental sites, facilities, and retail outlets.An example of Petroleume Management can be found in ………… which I’m going to explain in next slides:
The following examples Illustrate how GIS has been used to date.
Since its development as an automated system, GIS has served emergency management well. GIS can provide the information needed to support decision making before a disaster. During the early response period, emergency managers use GIS as a key intelligence source for the information they need to make decisions. And as the response moves toward recovery, GIS can identify those in greatest need to manage priorities.To be successful, GIS applications do not need to be highly technical or complex. In fact, simple is better. Whenever there is a need for a diagram or map to improve communication during an incident or emergency, think GIS.
Environmental impact analysis, disaster management and mitigation
Economic slowdowns around the world are forcing organizations to rethink how they operate. Many are realizing they need to find a way to do business smarter using in-house resources. Now is the time to invest in geographic information systems (GIS), a solution that has helped many organizations overcome their operational challenges and deliver improved profitability.Retailers, realtors, insurers, asset managers, and others seeking to understand markets better than ever before find that GIS assists in many ways: marketing, optimizing business openings and closings, segmenting consumer data, and managing fleets. GIS can visualize, manage, and analyze any business asset (employees, customers, and facilities, all the way to the supply chain network) because it has a place in the world.Discover what more than 300,000 Esri customers around the world have known for years—using GIS software and data allows them to make better, more informed business decisions.
Business intelligence (BI) is the practice of transforming data from disparate operational units into a common environment for analysis and reporting.
Location Analytics : The analytics blind spot • 80% of transactional data has a location component • Charts and graphs can’t always show what data is trying to tell you
GIS enhances BI analytics by exposing the influence of geography on behaviors, activities and processes. Adding maps to the reporting output of BI allows decision makers to easily visualize these same geographically influenced behaviors, activities and processes. These reports are an effective means of communicating geographically influenced performance information throughout an organization. The result of a successful BI implementation is improved decision making through improved analysis, and more comprehensive and timely reporting.
Integration of GIS with this common environment is much more cost effective than linking GIS to multiple, disconnected, operational systems.
