A Brief Note On Remote Sensing And Gis Technologies

___GIS allows us to re-examine what we know about the world by allowing us to study and understand places in the world in a much deeper level.

We believe this chapter gave a better understanding on globalization and migration. In “Remotely Sensed”, we recognized that the women that volunteer to be trafficked for sex work are usually migrant women who have difficulties providing for their families and finding jobs where they are from. This causes them to resort to prostitution, because they see it as the only job that could earn them enough money to provide for themselves and their families. We often see influential people with power speak about helping women get out of prostitution. Yet those same people in power support the state which holds on to the structures which refuses to give women equal working opportunities. This causes us to wonder if they are really interested in putting an end to human sex traffic or will continue to let it occur as it creates and puts money in the

plays a major part of our geographic information system. With all the advance technology today

Digital satellite (raster) makes it convenient to analyze with a computer and to integrate the data with GIS. It can be used in GIS to classify into thematic maps showing diverse themes such as land use, land cover, change, harvest cover, ect.

The maps not only show information, but also help people to understand the data by visualization.

Geospatial technologies comprise tools that enable surveying, mapping, remote sensing, photogrammetry and geographic information systems (GIS). It is therefore, largely an information oriented technology that specifically captures, analyzes, manages and uses various data to make geographical inferences that affect every sector of the current economy. The application of geospatial technology cuts across a wide spectrum of industries such as agriculture, security, intelligence, urban planning, facilities management, environmental management and telecommunication. In the US alone, the geospatial technology sector is worth $75 billion and is expected to grow even larger in future decades. In developing economies such as Ghana, which are faced by serious land management issues, geospatial technology is expected to assist in solving many of these problems mainly by improving the land records. This improved state of land registry has enabled land owners to access credit loan facilities more easily in order to use their land as collateral. Civil engineering has also been at the core of this technology and using 3D visual tools, engineers can easily represent detailed designs and other aspects of construction.

GIS or Geographic Information Systems is a software capable of gathering, storing, manipulating and presenting geographic information that its data is identified by its location (Stair & Reynolds, 2012). The company chosen for Rainforest is ESRI; they developed and GIS systems that function as an integral component that fits different type of organizations (ESRI, 2014). The software is designed to gather, analyze and display all types of geographical information. This works by simple five-step (Ask, Acquire, Examine, Analyze and Act) systems that lets any organization apply their GIS software to meet the organization needs that requires a geographic decision. Their GIS location-based analysis and data integration will help our organization supply chain visibility and get a better understanding of production to demand. The best feature of this software is the geographical view of any information management would need from the opening of a new facility to determining how each facility is doing (ESRI,

Maps are helpful in providing a symbolic representation of the different characteristics of a specific region or area. Mapping is meant to inform and guide us in our pursuit of knowledge as it helps to connect us visually to any location, from across the globe, to our own backyards.

The process of loading a map in SHP or DXF file format is easy and often successful. Additionally, obtaining maps from the internet by using the software is easy and often successful. One needs only to type the name or location of the sample area in a dialogue box and the software to obtain the map of the site where the sample area is present provided one's PC has an internet connection. The biggest problem with

GIS is a way of organizing large amounts of geographic information. It is not a tool, a software, a hardware or a specific image; it is a concept--a way of understanding maps (http://cnx.org/content/m13693/latest).

This GIS system has also a significant amount of features and is becoming more widely spread, and Sanchez-Lozano et al (2013) states it can do just as much as paid software. Therefore from the literature it seems beneficial to use an open source GIS system, as it is a viable option due to being easily accessible.

Geographic Information Systems pose many benefits to mankind. For instance, it has helped farms adequately provide the food we need for nourishment. GIS helps farmers make informed decisions on the best locations to farm and what benefits the lands can provide them, hence increasing their food production. The GIS software can be used to map land digitally while collecting important information needed to grow crops such as the topography or lay of the land combined with other statistical data allowing for easier analysis of the soil. In turn, this makes it easier for farmers to not only decide what and where to plant but also how to improve their methods of crop production so that they can earn more and better feed the world.

Geographic Information System (GIS) is a spatial information system for creating, organizing, integrating, querying, analyzing and displaying spatial data pertaining to real world. The integration of spatial data and attribute data and data from various sources is one of the strongest features of GIS. The spatial data in the form of maps, satellite images, aerial photographs, GPS observations and adhered to a common spatial framework are integrated in GIS environment for ‘what if analysis’ and spatial decision support.

Remote sensing and GIS provides a database from which the evidence left behind by disasters that have occurred before can be interpreted, and combined with the other information to arrive at hazard

The authors present an exploratory study using purposive testing among four different groups (scientist, non-scientist, agency manager and social scientist) included in the Coastal Landscape Analysis Modelling Study (CLAMS) in Western Oregon. CLAMS combines remote sensing with web base surveys. It was found that each participant had differing perspectives of the use of GIS to analyse and display natural resource data. For instances scientist believe that there is power in access to privileged knowledge such as data and GIS tools, giving rise to issues concerning credibility of maps produced using GIS as maps tend to be viewed as truth. I find this article beneficial to help build my knowledge of public involvement in Environmental Management and Conservation as many articles I have read are trending towards open source GIS and Public Participation GIS. It is also useful to get a grasp of the pros and cons of this topic.
