LizardTech / GeoExpress

The GeoExpress NPS contract has been renewed for an additional calendar year. Many thanks to the Natural Resources & Lands programs for making these services are available to all NPS.

The GeoExpress 6.1 client is available and can be attained through the EGIS website or your GIS coordinator.

Recommendations to use/optimize use for the NPS:

• Install - use 165.83.20.159 to access data cartridge (Tools > Data Cartridge > Use network ECM)
• What is the Data Cartridge? - NPS purchases 3TB of compression (data cartridge) capability per year. The Data Cartridge is the method that Lizardtech uses to monitor use.
• Important! The data cartridge is consumed the first time an image file is compressed, mosaiced, etc. Subsequent compressions do not consume cartridge. The recommended data flow is as follows:
  • Create a test image prior to processing or batch processing imagery (NOTE: tagging as test image does not consume data cartridge)
  • Process raw imagery and create lossless .sid
  • Store/archive lossless .sid file(s) for future processing
  • Important! Subsequent GeoExpress processing does not consume data cartridge.
  • Continue with work flow re-projecting, color balancing, mosaicing, additional data compression, etc.
• Some data which is available or in process:
  • National Geographic TOPO! - procured through NPS Fire program. Data available as lossless .sid. Available through Regional GIS coordinators, Fire program and EGIS.
  • DOQQ - Work in progress lead by NR.
• LizardTech site - Note knowledgebase under support.
