Hurricane winds through a GIS
Score 8 out of 10
Overall Satisfaction with ArcGIS
Initially is was used by me to analyze and characterize the historical trajectories of hurricanes in the Atlantic Ocean.
Its versatility and ability to work phenomena in geographical coordinates and across different time zones allowed me to analyze the behavior of hurricanes since 1851. With other programs such as AutoCAD it would have been impossible to do so. It is currently being used to characterize the rainfall pattern in Venezuela. Different people of the company are being trained in the use of this tool, with the local commercial representative (Esri).
- It allows to work and analyze phenomena on a large scale.
- The fact that one is able to work in geographical coordinates makes it much more versatile for these tasks than programs such as AutoCAD or similar, designed to work in smaller domains.
- The interpolation functions that it has can be extended and improved.
- The interface with the user can also be improved so that any user who uses it for the first time, can access to understand the program more easily.
- For me it has been excellent, both personally and for the company where I work.
- It allowed me to develop my work of promotion in the university where I impact classes, work that allowed to develop a map of probabilities of risk associated with the action of the hurricanes and its connection with the climatic phenomenon known as ENSO.
- It was also of enormous utility to the company where I work, which devotes a large part of its activities to developing offshore oceanographic measurements, linked to the oil and gas activity because it allows a better management and knowledge of the risk associated with each job
- Capaware, MapGuide, Map Server and Open Sourc
Another geographic information tool that I have used is Google Earth, very useful for basic tasks, but which does not remotely have the capabilities of ArcGIS. Specifically, other GIS software that I have used in the recent past was the Map Server, the MapGuide Open Source, and the Capaware, because they were free software.
It is the most functional program that I have found so far, both because of the variety of georeferencing datums and coordinate systems, allowing to pass from one datum to another with great ease. In global meteorological and oceanographic studies, its value is very high because it allows the complete visualization of the phenomenon that is to be studied, and at the same time it allows sensitivity analysis when turning off or igniting certain variables in certain years or areas.
Its weakness, in my opinion, lies in the methods of interpolation that it has because they can lead to erroneous interpretations, depending on the skill and experience of the user.
The people who use this software have very specific objectives. Some are geologists, others are assistant engineers, whose chiefs have requested that they are instructed in order to assemble and articulate databases of a different nature, so that they are accessible to potential customers and internal users who are frequently requesting data and statistics. that are not at hand, but managed by certain departments.
They should be people with general knowledge of spatial georeferencing, who understand elementary concepts such as latitude, longitude, time zones, horizontal and vertical reference datums, geoidal and elopsoidal heights. Furthermore, I think it is desirable that they have managed or used data in other databases and that they really understand what is the intrinsic utility of a geographic information system.
- Generation of geological risk maps.
- Generation of risk maps by hurricane action.
- Articulation of a large database with various meteorological and oceanographic variables.
- Allow such data to be seen by any user with permission from anywhere and at any time.
- For commercial purposes, allowing showing the strengths of the organization in relation to the large amount of data it has and the analysis thereof, before any customer.
- Guarantee the perpetuity of the data, since having it properly stored avoids its possible loss over time.
Simply because the program deserves it. It seems to me that it is a fundamental tool for the storage, analysis, and interpretation of medium and large-scale phenomena, unmanageable with traditional engineering software. Its versatility in the handling of the different "layers" with which the data is handled and interpolation tools, make this software a powerful ally both for companies and for the educational part of the universities.
