layered concept

LAYERED CONCEPT BY :- BASEERAT AMIR REVA UNIVERSITY “SEC C”

DEFINITION OF LAYERD CONCEPT UNDER GIS

The visual representation of a geographic dataset in any digital map environment.Conceptually, a layer is a slice or stratum of the geographic reality in a particular area, and is more or less equivalent to a legend item on a paper map.

GEO earth mapping

WHERE IS IT USED AND HOW IT IS USED EVERWHERE.• IT IS USED IN PHONES.• IT IS USED IN SURVERYING.

IN SHORT, IT IS USED IN ALL THE PLACES WHERE GIS IS USED.

WHAT IS LAYERD CONCEPT SO, LET US IMAGINE ONE TREE .WE CAN EASILIY KEEP TRACK OF THIS TREE LIKE ITS EVERYTHING .

NOW LETS THINK THERE ARE MORE THAN 1000 TREES HOW DO WE KEEP TRACK OF IT.THIS IS NOT IT WHEN WE ARE DOING SURVEYING OF A FOREST WE NEED TO KEEP TRACK OF MANY MORE THINGS LIKE RIVERS, STREAMS ,SOIL QUALITY ETC …..

HOW DO WE DO IT ?

HERE IS WHERE LAYERING CONCEPT COMES  Our information on trees would constitute one layer of information. We could also have a layer with rivers and a layer with soil types. Any information can be represented as a layer.

LAYERD CONCEPT IN EVERYDAY USE

IN OUR PHONES WE HAVE MAPS.MOST COMMONLY USED ONE`S ARE GOOGLE OR NOKIA MAPS. WE HAVE LOTS OF OPTIONS IN TO CHOOSE FROM LIKE SATELLITE VIEW OR A NORMAL VIEW OR TRAFFIC VEIW . OPTIONS -------

THIS PICTURE IS A SCREENSHOT OF GOOGLE MAPS MOBILE APP

THIS IS HOW OUR COLLEGE LOOKS WHEN WE USE DIFFERENT

OPTIONS THE FIRST PICTURE SHOWS US THE TERRAIN…….

THIS THE MOST COMMONLY USED OPTION ......THE SATELLITE VIEW .

THIS VEIW IS THE TRAFFIC VIEW …..IT SHOWS US THE TRAFFIC CONDITION IF ITS YELLOW THEN THERE IS LITTLE TRAFFIC ,IF RED THEN FULL TRAFFIC AND IF GREEN NO OR VERY LESS TRAFFIC

LAYERD CONCPET

CAN TERM AS THEMES…..

SO FINALLY LAYERD CONCEPT ITS NOTHING BUT DATABASE OF DIFFERENT DATA COMBINED AND SHOWN AS LAYERS.THAT IS ,ONE AFTER THE ANOTHER.

THIS CONCEPT IN A CIVIL ENGINEER`S LIFE :-

IT IS VERY IMPORTANT FOR US TO UNDERSTAND THIS CONCEPT AS GIS HAS BECOME THE MOST COMMANLY USED WAY OF SURVERYING …….SO WE THE NEW GENERATIONS OF ENGINEER`S HAS TO KNOW EVERYTHING WHICH INCLUDES SOFTWARE LEARING .
