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 8 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 sidlic.nps.gov 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.
