LTPP Products Online has been rebuilt to take advantage of the latest internet technologies
as well as new data from the LTPP program. The flagship of the site DataPave Online
has been rebuilt from the ground up. Among the new features are the release of never
before available LTPP Ancillary Information System (AIMS) videos and images from
the LTPP sites. Not all videos and images are available at this time but more will
be added in the future as the LTPP program releases them. The navigation map on
the site has been updated using the latest Google mapping technologies. The new
site has redeveloped the way users can view and extract data. A new data summary
sheet view has been developed and enhanced to display as much information as possible
related to the LTPP site experiment. The site has completely integrated the previous
standalone application Distress Viewer and Analyzer (DiVA) into all the new features.
DiVA is no longer a standalone product. All charts and graphs from DiVA can be seen
within the integrated data sheet view. New export tools such as “Export by Topic”
have been developed with the users in mind, making this the most talked about feature
on the site. Users can now select multiple data elements and directly view the amount
of available records even before a download is made! The site has also incorporated
a new streamlined and efficient LTPP reference library system that is completely
searchable using keywords. A new feature called LTPP IMS A-Z has been added. This
is a great tool for beginners to get to know the information and data available
from the LTPP program. Much like other sites on the web the LTPP IMS A-Z encapsulates
topic and sub topics areas within the LTPP data, click on your preferred topic and
get a listing of documents and data elements related to that topic. If you’ve reached
the data you want click on the “Get Data” button and the site will take you to the
“Export by Topic” page which will let you further refine your selection and get
the data you want. The site has new and improved performance. It has gone from 3
Mbps to 6 Mbps bandwidth. This translates to faster download and access times for
videos, images, and maps. Of course most of the user expected features such as table/field
navigator, data dictionary, data codes, table export, SQL export, and export history
are still available. The site now hosts the most up-to-date Standard Data Release
(SDR) 25, with SDR 26 coming soon in the winter of 2011. Please take a close look
at the site and help us by providing comments in the discussion group area of the
site. Are you happy about the changes? Are you unhappy? Did we miss something? Would
you like to see something else? Please let us know so we can improve the delivery
of LTPP data to you, our users!
