The GIS GateWay

What is GIS? it is a computer system designed to capture, store, manipulate, analyze, manage, and present all types of spatial or geographical data > data that has location. This is actually a question which everyone who doesn't know about GIS asks themselves. I have came across this quiz severally being asked by my friends. Below is a hierarchy kind of, steps to building your GIS career.   GIS Intern Almost every higher level (Technician, Analyst, etc.) position will require some hand-on job training.  The best way to achieve this is through an internship.  Internships are mostly low-paying, part-time jobs but they are the best way to get further GIS training and to develop your GIS skills in a real world setting.  Learning GIS out of a textbook is a great way to get started, but in reality, few GIS tasks are solved as neatly as the “follow steps 1-10” of your workbook.  Getting an internship has become more competitive in recent years. ...

Universal transverse Mercator In Kenya is the mostly used map projection due to its accuracy in conformality hence preserving the shape of the earth. Global Features of utm i)   20 latitudinal belts of 8 deg in the N-S directions labeled from C at 80 degrees South-72 degrees         South to X at 72 degrees North -84 degrees North .     Kenya in belt M and N (ii)  The  origin  of  longitude  is  the  central  meridian.  The  origin  of  latitude  is  the            equator (iii)  False northing is 0 m N but 10,000,000 m S  for southern hemisphere to avoid the          use of negative figures. (iv)  False easting is 500,000 m for each zone (v)  Scale factor at central meridian is 0.9996 (vi)  Latitude varies from 84 degrees north to 80 degrees south The reference ellipsoid used in Kenya is...

Remote Sensing is interesting alongside GIS analysis. They both collaborate when it comes to performing some functionalities. I produced my very first Map  from a layer-stacked satellite imagery bands using ERDAS  IMAGIN software for image analysis after which ArcGis desktop ArcMap assisted me in creating the map layout. Its beautiful  though not all features are classified. As some people say Learning is a continuous process, then keep learning new things every day.

Hi all, i read this somewhere and i found it good to share with you, especially my classmates. Hope you'll benefit. DISTORTION PROPERTIES IN MAP PROJECTIONS angles, areas, directions, shapes and distances become distorted when transformed from a curved surface to a plane all these properties cannot be kept undistorted in a single projection usually the distortion in one property will be kept to a minimum while other properties become very distorted 1. TISSOT'S INDICATRIX is a convenient way of showing distortion imagine a tiny circle drawn on the surface of the globe on the distorted map the circle will become an ellipse, squashed or stretched by the projection the size and shape of the Indicatrix will vary from one part of the map to another we use the Indicatrix to display the distorting effects of projections 2. CONFORMAL (ORTHOMORPHIC) a projection is conformal if the angles in the original features are preserved over small areas the shapes of object...

MAP PROJECTIONS  A map projection is a systematic transformation of latitudes and longitudes of location on the surface of a sphere or an ellipse into locations on a plane surface. Re-projection- it is the transformation from one coordinate system to another coordinate system. Projecting the globe into a map is very essential for easy storage, retrieval and even transportation from one place to another since it can be folded. Today, I am going to just state the different types of projections being used across the whole world.   TYPES OF MAP PROJECTIONS  1. Planar projections- orthographic                                    -stereographic                                    -gnomonic 2.Conic projections  -Albers Equal area                 ...

 GIS plays a key role in each and every field which is applied to. the following are some of its benefits among others; 1. Better storage and updating of data 2. More efficient information retrieval 3. More efficient production of information products 4. Rapid analysis of alternatives 5. The value of better decisions

1. It allows change detection 2.It provides a multipurpose data 3. It takes a wide area coverage 4. Cost effective 5. Suitable for difficult areas
