The Context and Imaging Basics: Technical Infrastructure , Presentation and Preservation

Imaging software available

Aware Inc. ArchivePack: Imaging software, build upon Jpeg2000 (an ISO standard); Includes Aware JPEG2000 Image Server Toolki, JPEG2000 SDK (for image

compression, decompression, and formatting), Batch Processor, JPX SDK (to add and remove metadata), and Metadata Editor.

GeoExpress 6.1 Geospatial imaging software, can view both JPEG 2000 and Mr. SID (the industry-

standard image compression format); Requires installing the server side scripts.

ContentDM Support standards including Jpeg000, Dublin Core 1.1, VRA, XML, HTTP and OAI; Integrated OCR facilitating full-text search.

LuraWave JP2 Developed by Lura Tech. Support Jpeg2000, and requires image content server; Lura Tech also has a free plug-in which enables viewing and saving JPEG2000 online:

The Early Sedgwick County Township Maps Project

About the map project Digitized maps of the Early Sedgwick County

Townships and introduction materials; Include survey maps and atlas maps; Held in Special Collections and University Archives at

Wichita State University Libraries.

Project planning

Scanning: outsourcing Survey maps at 400 dpi, atlas maps at 600 dpi, saved

as tiff files originally.

Jpeg2000 Viewer Test

Jpeg2000 Viewer Test

ActiveX Control for IE (plug-in, from Lura Tech) was downloaded;

Some tiff files (about 100 to 150 megabytes each) were converted to JPEG2000 format using LuraWave SmartCompress (free, downloaded from Lura Tech website); the compression rate is 22:1, and the converted files range from 5 to 7

mega byte each;

The converted JPEG2000 files were put online first in the “JPEG 2000 Test” section of the “help” page, and then were added to “browse” page as a link below the thumbnail;

This plug-in has very limited zoom function online, but it allows users to save the file;

Decide not to enable saving of JPEG2000 images due to the copyright concerns.
