5 skills required for success in the field of GIS

ESRI Education Manager, Joseph Kerski, wrote an article about the five skills or abilities needed for a successful career in the field of GIS. To-5 expertise or skill is 2 or 3 of them are also must-have skills for successful careers in other fields. So what skill or skills are they?

The first skill for a successful career in the field of GIS is curiosity or the curiosity / wonder is great. They are a successful career in the field of GIS is not only curious about the world of geospatial technologies, but they also want to know about the world itself. They reflect the spatial relationship to work in a local phenomenon to a global scale, ranging from demographics, land use and traffic patterns within their own communities to natural hazards, biodiversity, and climate around the world. This triggers the curiosity that is often necessary to solve the problem by using GIS.

The second skill is the ability to work with data. They are a successful career in the field of GIS has developed the skills to think critically about the data. They not only know where to find data, but with a very good understanding of metadata so that they know the benefits and limitations to work with any kind of data type. They understand well what is the most effective measures to collect, analyze, and display geographic data in the application / GIS software.

The third skill for a successful career in the field of GIS is a basic understanding of geography. GIS practitioners must know the fundamentals behind all spatial phenomena, including map projections, datums, topological relations, spatial data models, database theory and methodology, ways to classify data, how to effectively use spatial statistics and geoprocessing methods, and much more the other.

The ability to adapt quickly is the fourth skill necessary to succeed in the field of GIS. Now this geospatial technology is developing very fast, as fast as other technologies. Cloud computing technology, the choice of GIS data access via the desktop platform or mobile device, access data online is the latest technological developments, as a professional career in the field of GIS, adaptation to technology and flexibility in the application of technology should be a must-have their own skills. This also applies to a successful career in other technologies. Inevitably, they must not only willing to change, but accept and embrace change as an important part of their careers. They are lifelong learners.

The fifth skill is good communication skills. They are a successful career in the field of GIS know how to use GIS and other presentation tools to communicate their work to various audiences. They understand well how to effectively use elements of maps, but they also knew how to communicate the results of their analysis in oral and written reports, visually via video, face to face, online, and through other means.

Surveyor role in optimizing the tax revenue from mining sector

Energy needs of today's surveyors felt increasing. One of the agencies that are now being actively surveyor holding power is the Directorate General of Taxes. As a vital institution that sustains more than 70% of the financing needs of the country, the Directorate General of Taxation deems it necessary to optimize the revenue from the mining sector, especially of oil and gas. Given that the government has issued a total of 9000 permits the mining business, something that makes sense if the Directorate General of Taxation want the optimal revenue from this tax the mining sector. The use of an independent surveyor is expected to complement the existing system of tax collection. With the accuracy of the data from the Surveyor, the error reporting in the concept of self-assessment can be minimized. The involvement of agency surveyors can help provide information on production data, the number of export and production costs of the company mines. With accurate data, the government can control and monitor, so they can know the accurate amount of tax revenue from the mining sector. For that, as of 1 April 2012 the government in this case the Directorate General of Taxation Tax Office will operate in a deposit of Oil and Gas based in Jakarta. Establishment of this office aims to enhance the ability of tax officials in calculating taxes from oil and gas sector. Hopefully the government's desire to hold an independent surveyor could be realized, so the optimization of tax revenue from oil and gas sector better.

GEOEYE?

GeoEye is the creation of the earth observation satellites are satellites that was launched on 6 September 2008 sponsored by Google and National Geospatial-Intelligence Agency (NGA) of California, the United States. Earth observation satellites is GeoEye commercial satellite imagery with the highest resolution images that exist in Earth orbit today.

GeoEye satellite has two satellites that GeoEye-1 and GeoEye-2. GeoEye-1 satellite launched by GeoEye Inc. who had also been issued IKONOS satellite which is sub-meter satellite a world first. GeoEye-1 is equipped with advanced technologies, used also by the artificial satellite company General Dynamics. GeoEye-1 satellite construction will cost $ 502 million a bear is Google and the NGA as its main sponsor. There is a Google logo is displayed on the side of the Delta II rocket is a rocket that launched GeoEye.

ITT Corporation is a maker of cameras on the satellite sensor is then in January 2007 sent to General Dynamics to be integrated into the GeoEye-1. Aerial photographs Kutztwon University Campus is the first image produced by the GeoEye-1 after the calibration process is complete.

Software Specification and GeoEye

GeoEye satellite capable of producing images with resolution up to 0.41 meters with a black-and-white sensor and 1.65 meter for a color sensor. Image resolution capability is owned by GeoEye is ideal for large scale mapping. GeoEye's orbit at an altitude of 681 km above the Earth and moving at 7.5 miles per hour.

GeoEye can map natural and man-made features to within 3 meters of the actual location on the earth because of GeoEye has a three-meter accuracy. In other commercial imaging system, this level of accuracy never achieved before, ever.

GeoEye has a very high accuracy and can collect a lot of images on a single pengorbitan. ITT was designing these satellites to be able to shoot multiple targets at all orbits. To get a thorough imaging, satellite was programmed in order to move forward, back, right and left of the target.

Frequency GeoEye Pengorbitan

GeoEye to orbit with a frequency of 15 times a day and takes 98 minutes to orbit. This satellite is also used to complement the IKONOS satellite system, but in the process of collecting GeoEye satellite images much faster which is 40% faster to collect black-and-white and 25% faster for color images. Both of these satellites in a single day can synthesize 1 million sq. km imaging results.

In black and white mode, GeoEye can perform imaging of an area of ​​700 000 km2 or area of ​​the city of Texas, while in color mode can GeoEye imagery covering 350 000 km2 - with the help of the camera optical telescopes, detectors, focal plane and the digital processor.

GeoEye Satellite function on Google

GeoEye satellite used in the web-based map service Google Earth and Google Maps. In addition to Google, GeoEye also provides data with high resolution imaging results for the interests of the United States through the NGA.
