The Ministry has more than 20 offices spread around the province, some in remote places with low bandwidth. Personnel at the various locations view geospatial imagery both in web applications and as contextual layers within ArcMap and GeoMedia.
Multiple offices were purchasing the same data on CD-ROM for their locations – a costly redundancy in terms of both money and storage space. This decentralized image sourcing also created difficulties in managing and updating the imagery.
Efficiently manage, update, and distribute imagery from a central location
Make imagery accessible to entire Ministry workforce
Reduce file sizes of stored images while retaining high image-quality
Mosaic and compress data in an efficient workflow
Support viewing by analysts using WMS-enabled web applications such as ArcMap and GeoMedia
The Ministry turned to GeoExpress for mosaicking and compression to MrSID files, and Express Server for efficient distribution to any device over any connection.
With these solutions, the Ministry now makes a single purchase of image data, then uses GeoExpress software to convert TIFFs to the industry standard MrSID format, simultaneously eliminating 60% of data storage costs and taking advantage of easy-to-use image processing tools such as color balancing, mosaicking, and reprojection. GeoExpress retains high image-quality.
The Ministry then uses Express Server to distribute the imagery among its offices and personnel in the field for use as image layers in ArcMap and WMS-enabled web applications. Now, personnel anywhere can quickly view any of the Ministry’s image data from one central, easily-updated repository.
The Québec Ministry of Sustainable Development, Environment, and Parks realized the following benefits using GeoExpress and Express Server:
