GeoStor More Data & Updates
Additions:
These orthos have not been added to the High resolution ortho service. We are still working on our long term strategy to handle the high resolution orthos in an timely manner.

GeoStor Updates
Whew. What can I say, been really busy as usual and haven't posted any updates in awhile. So without further ado, here they are:
- Upgraded ArcGIS Server to 9.3.1 and converted all our services over to the new MSD format. They are very fast! I should have done this a long time ago!
- Our services should be accessible from anywhere or any application now.
- We have setup a geometry service, check it out: http://www.geostor.arkansas.gov/ArcGIS/rest/services/Geometry/GeometryServer. This mostly for developers and applications but it is a very useful service.
- VMware ESXi has been upgraded to 4.0, this is the software we use to virtualize our servers.
- The production servers have been migrated to bigger, badder and faster hardware and I am going to use the old servers to build a SQL Server 2008 cluster.
- You can now search the dynamic layers on the GeoStor viewer. Go to http://maps.arkansas.gov and click on the Search widget, there are examples for each layer to search by.
- Our latest blog posts display on GeoStor now
Coming Up
- Upgrade FME Server from 2009 to 2010, need to test in development first though.
- Possible Image Server implementation?
- Migrate FTP server off old hardware to virtual machine
Gotta get back to work now J

ArcGIS Image Server Extension- Discussion
Why
Several cities and/or counties in the state of Arkansas have acquired 1 foot and six inch ortho photography. They are interested in making the data publicly available via GeoStor (thank you). AGIO staff believe this will be a growing trend and want to be prepared to distribute the data in a useful and timely manner.
Issue
1) The data is provided in multiple projections and coordinate systems. While this is perfectly acceptable, it proves to be a challenge on several fronts when creating/combining services and providing the data as a clip, zip, ship
2) File sizes for the 1 foot and 6 inch data are large. Several have had issues downloading the data from the ftp site. The increased resolution generates a clip that generally exceeds the 2GB limit. Though other formats do support larger file sizes, there is still the download issue (discussed above).
3) Currently, a number of ortho data sets are stored in multiple locations (SDE/FTP). This results in duplicative (actually more due pyramids) disk requirements. Side note- disk isn't cheap regardless of what has been said in the past. GeoStor currently host roughly 10TB of imagery (SDE/FTP combined). This number is excpected to grow by X with the additional of more high resolution data.
4) The current process to get the data published to all the various services is time intensive (often even months). Bench mark test in other states have demonstrated processing times are dramatically reduced from months to days.
Possible Solution
ArcGIS Image Server has been implemented successfully in several other states. The product would provide the ability for the data to be stored in a single location on the FTP. Image services would actually be generated from the files on the FTP disk. This would provide for the opportunity to provide additional image services for historic ortho imagery.
Known Impact
The following are a list of impacts that we thought of. We feel sure there are likely others and are interested in hearing from you.
1) All current image service URLS would change. This would require those with saved connections to reconnect.
2) GeoStor Staff would have to change paths in a number of applications. We can live with that if we move forward.
3) Capability to download high resolution orthos via clip, zip, ship would discontinue. 1-meter statewide orthos remain available for clip, zip, ship. Users can obtain a significant area of 1-meter data.
We would like to hear from you. Have you used image server? Would changing the url paths greatly hammper your work? Other thoughts or questions?

GeoStor Download Issues
The download issues should be resolved now. They were unrelated to the FTP outage, it was one of those "I'm going to do this to fix this issue but then it broke something else" things. If you got a failure or nothing at all, please resubmit your download.

GeoStor Outage Resolved
The file system repair has completed and as far as I can tell everything is functioning properly again. Unfortunately, if you submitted any downloads today you will have to resubmit the job. Let me know if you run into any issues that may be related to this outage.

GeoStor Outage
Our FTP server has experienced some data corruption and I am attempting to repair it, however this means that Downloads are down as well. I expect the repair process to continue though the evening since the disk being repaired is 2TB in size. I have posted a notice on the GeoStor home page and I will do another blog post when everything is resolved.
