Thanks for your question. I think the answer depends on what you want to do. As you say there are many different sources of remotely sensed data, and if you know what you want to use it for, I might be of help. Many of the space agencies are interested in working in the Caribbean, but its proving difficult to make things happen for various reasons.
There are so many different things remotely sensed data can be used for, it would be great to get a feel for what you are interested in using it for so that we can start brainstorming about the topics for the webinar you propose.
What do you think?
Thanks much for your response. I am thinking Remote Sensing data may be new to some Caribbean territories. As we seek to know more and learn more I am thinking some examples of what it is used for in different countries may help the process. Don't know how others feel about that but I really think it will help.
Let me hear from others what they think?
St.Vincent & the Grenadines
Remote Sensing is the foundation of accurate data extraction and dataset development. Depending on your education level you can do more and more with the right data sources. Most of my shapefiles are from a set of 2002 images of SVG which I have developed for over 5 years now. I recently made a proposal for the purchase of 2013 imagery so that we can have a more accurate perspective of our countries resources that can be mapped.
In terms of the various uses to which we can use remote sensing, St Vincent is at a beginners stage at the moment. I see forest mapping as the perfect application for good imagery, but the seriousness and dedication has not been established locally. I just joined the group!
I just wanted to point you to this website above. As Adrian says, remote sensing is a means to an end and not an end in itself, i.e. there are so many things you can do with it, that it will take some time to explain everything. :-)
World Bank has a project with the European Space Agency, called EO world, where during phase I, 12 projects were funded to demonstrate the usefulness of remotely sensed data for various purposes. The link I posted above will take you to the page where the report from phase I can be found.
I hope that gives you some ideas of how it can be used.
Hi Phil, I work at NASA Goddard Space Flight Center and lead various satellite projects that are trying to show improved discovery and delivery of products for end user consumption. I have access to a variety of optical, infrared, and radar satellites that can provide new images in addition to archive data. I think there is a video of me speaking at the advanced spatial data management workshop held in Trinidad a few months ago. If you'd like to discuss more about how to get products, not just data, contact me at firstname.lastname@example.org. Take care, Stu
Free Data Sources
Earth Observation data and data products provide crucial information for disaster risk management and emergency response. Many datasets are available free of charge and can be downloaded from the web. Others are available as free web-services. The UN-SPIDER team has compiled relevant data sources for you:
- Hazard Specific Datasets (Hydro-Meteorological Hazards, Geo-Hazards, Fire, Pollution, Insects),
- Digital Elevation Models, and
- Land Use and Land Cover Maps.
- Satellite Data and
- Search Engines for Geospatial Data (where you will also find graphical viewers to search geospatial data for different hazard types).
(Floods, Drought, Storms,Temperature)
(Earthquake, Mass Movement, Volcanos, Tsunamis)

I work at NASA and have just posted a 10m true color image of St Lucia to the general website. Please let me know if you don't see my posting and I'll send it to you directly. email@example.com
Hello to All,
Thank you to all who respond as many valid points and information were shared. The use, as mentioned, for RS data is boundless, so I intentionally did not want to restrict the input of the discussion by being too narrow. If any one has any specific expertise or interests though, a focus on land deformation (erosion, subsidence, slippage), coastal monitoring, water catchment and flood mapping, are all good starting point for our region. There are of course, a myriad of important vegetative applications that are useful as well. The ability to monitor and detect change is a powerful tool that RS offers and is a heavily under tapped resource in our region.
In browsing through some of the links referred to in the responses, it was noticed that some of the sites require special approved login to access the data. I am not sure if this is mainly for military or institutional personnel only or if there is a general protocol in attaining access. Some sites had 'broken links' if you tried to go to the request data page. Also noted was the lack of Radar and SAR imagery available especially in recent years. Radar imagery is particularly helpful in the Caribbean region due to the constant cloud cover. I was again reminded of this while viewing the link of the satellite image generously provided by Stuart Frye above (Thank you!) .
If anyone has more information on SAR imagery or ability and protocol to gain access to site data, I'm sure it would be of great benefit to the discussion group,if shared.
