MAP PROJECTIONS IN GIS

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
                                  -Lambert conformal conic projection

3.Cylindrical projections-Mercator projection
                                        -Transverse Mercator
                                         -Universal Transverse Mercator (UTM)

Keep thinking spatially and GEOCODING!
                     keep in touch for more geoposts coming.

                                    leave a comment for consideration... thanks

A PROTOCOL EVERY WEB MAPPER MUST KNOW- HTTPs

HTTP stands for Hypertext Transfer Protocol . It's a stateless, application ­layer protocol for communicating between distributed systems, and is the foundation of the modern web.  As a web developer/Mapper, we all must have a strong understanding of this protocol. HTTP allows for communication between a variety of hosts and clients and also supports a mixture of network configurations through the internet. it does not keep state between different message exchanges hence making itself a stateless protocol. The communication usually takes place over TCP/IP , but any reliable transport can be used. The default port for TCP/IP is 80, but other ports can also be used. The client sends a request to the server (host) and receives response just on his/her browser. The current version of the protocol is HTTP/1.1, which adds a few extra features to the previous 1.0 version. The most important of these, in my opinion, includes persistent connections, chunked transfer­-coding and fine­-g...

Converting ARCMAP .shp to Adobe Illustrator .AI file

Hello dear Geo-geeks, Its been a while long time since I post geo stuff here, today I would like to take you through on how An ARCGIS .shp file can be converted to .AI file for further Graphic designs. Exporting From ArcGIS to Illustrator Adobe Illustrator is a vector drawing program that accepts files of type .AI. This software can be very useful if you wish to use geometry from GIS as the basis for diagrams that you would create in illustrator, or if you want to use illustrator to fix some of the awkward legends or labels that ArcMap makes for you. TRICKY features of Adobe Illustrator includes; None of your layers can use transparency  If you are using special fonts or spot symbols, they must be converted to polygons in illustrator. There is a limit to the number of vertices that can be exported to illustrator.   Those are the important rules to remember in arcmap document. Setting up your ArcMap Document You may have designed a map in ArcMap wi...

Expanding Geospatial Minds

WELCOME TO GIS WORLD Hello everyone, Its been a while since I posted something here. Today, I want us to look at how one can become a GIS professional from scratch. This actually was triggered by  receiving so many Questions from social media about what Geo-spatial and Remote Sensing as a course is. Well, many of them were freshers who have been placed to various universities to study the course while others just curious about the course and wanted to know if it can be a lifetime profession to consider.  For my case, I never had a glue of what GIS & RS was back in 2014 when i joined the University. Since there were little knowledge about it in Kenya by then unlike now, I never got anyone to guide me if the course was good or not. Then I just applied and boom, I was LUCKY! to get an opportunity to study this new...
