To fulfill the request of a vendor, I need to squeeze our various years of Digital Ortho Photo Mosaics from 200 - 400 GB each down to 35 GB for each year. They want TIFF format. It takes many hours - I don't know how many, but more than 6 hours -to copy and compress a raster mosaic from our SQL/SDE data server to my PC. Around midnight I will kicked off the server as other data in the SQL database is updated. If it takes more than 15 hours it may not be possible. The vendor specified using 'Create Raster Dataset', but an ESRI tech told me that is designed to combine raster data, not copy. That doesn't make intuitive sense - I thought raster images had to be sewn together. I've found little help online for this task. Is COPY RASTER the best way to do this? Is TIFF the best format? I thought JPEG or PNG were better compression formats. Is there a non-iterative way to determine what 50% or 75% compression means in the final product? I can't believe it's a simple, linear equation; i.e., a 100 GB file compressed by 75% becomes a 25 GB file. But I could be wrong. I expect a 400 GB DOP mosaic compressed to a 35 MB Tiff to be unreadable, but I was asked to do it, not question it.

I would like to use ArcGIS Explorer (AGX) with no basemaps - in fact, no internet link at all. The County's Roads and Bridges Department needs to view the GIS roads we maintain as they populate and proof PubWorks. I can't determine how to use no basemap - because even if I delete the basemap AGX is slow and seems to be reading from ArcOnline anyway. Lat/Longs appear although our data is State Plane. The Arctic circle, tropics and equator also appear. I don't want any of that. The screen with no basemap appears below.

Permissions across the network My workstation, to the server, then to MS SQL/SDE files have driven me to great anger. I finally convinced my director to use admin permissions for both of us in ArcGIS and Freeance – and 90% of the problems are gone. It’s still easy to make a tiny mistake.

There are too many variables. This is a task for an ESRI tech to log into your system and make it work. I am not a data expert. In Spartanburg I get data from the County MS SQL/SDE data structure. What I know about SQL wouldn’t fill a thimble. I had a problem where the GIS director could reach data that I coud see, but I kept getting errors on. That turned out to be ESRI ‘privileges,’ – permissions. Rebooting your workstation (and server if you have that authority) sometimes clears errors. One thing I have learned is that MXD files trash easily. Build a new, simple test MXD from scratch, do the data link from ArcMap to ArcGIS Server from Server properties and import the data from your workstation. If you have full control you should delete existing data connections from the server, then add them from ArcMap. The test the application with the simplest couple of data sets. To state the obvious: The purpose of registering data is to make sure that your ArcMap MXD and ArcServer see the same data. When I worked for a university, I didn’t use SQL or SDE. I didn’t do cadastral data. All I had to do was either map my MXD to, for example, Z:\campus data then map ArcServer to the same data with the same pathing. It’s easiest if both machines see a third drive. When I first ran into registration I would create an D:\drive on my server and copy the data from the D:\drive of my workstation. That was a kludgy workaround, but it showed me the obvious: if ArcServer can use the path in the MXD and it finds data in the same place, it will use it. The import system always works for me and ensures I don’t make spelling errors or select a similarly named SDE link file.

I was given an easier way to register databases with the server by Bethany at Esri tech support: It obviates any chance of mis-spelling. You start in ArcCatalog, choose your ArcGIS Server (admin) and select server properties -- [this is 'esri-speak' or elementary school teacher polite 'we' stuf]. I'm not this polite. -In ArcMap, we right clicked the name of your connection to GISISS under "GIS Servers" -We then clicked Server Properties -We then clicked the Data Store tab -We clicked the + button to add a new registered database -We clicked "Import" and selected the connection to the geodatabase that we needed to register -We clicked ok, and this resolved the error message you were seeing when publishing your map
