"Contrast Stretched" MrSID and JPEG 2000 files now available FEBRUARY 23, 2007 - MassGIS is pleased to announce that a new set of "contrast stretched" images in both MrSID and JPEG 2000 format are now available for download and order. These contrast stretched images may help solve some of the problems that some users encountered with getting the original images to look the way they wanted. These new images have a much greater contrast when compared to the originals and should be welcomed by users who do not have the software tools to modify the appearance of the original imagery.

Both MrSID and JPEG 2000 files available for download; MrSID Mosaics available to order AUGUST 3, 2006 - Many of you have been eagerly waiting for the new 2005 color orthoimage basemap to become available. MassGIS is pleased to announce that along with the previously-released MrSID images, JPEG 2000 versions of the data are now available for download. These files are tiled using the same orthoquad (OQ) index used for our other image datasets. All 1,554 images have been delivered and 3-band (RGB) MrSID images were posted on our ftp site for free download on June 28. Four-band (RGB and Near infrared) lossy JPEG 2000 versions are now available as well. In addition, regional MrSID mosaics may ordered from our online order form. *** Please note that the 627 MrSID images previously available on the ftp site in March have been removed and replaced with newer versions of the data (as of 6/28/06). *** Other products, available for purchase on CD-ROM, DVD, or user-provided portable hard drive, including the original GeoTIFF deliverables, lossless JPEG 2000s, regional image mosaics and elevation datasets, will become available over the next few months. Finally, a one-meter raster interpretation of impervious surface for the entire state will be available as well. MassGIS will be trying to distribute all the products as quickly as possible. We ask for your patience. It will be well worth the wait! For more information see the 1:5,000 Color Ortho Imagery (2005) Datalayer Description page. |
