ArcGIS Server

2009 ICIT Midyear ConferenceCory Hines

Linn County, Iowa

ArcGIS Server Environment• MS Server 2003– Dual Quad Core 3GHz– 4GB RAM

• SOM/SOC on single server– All projects/locators on local

drive– All data in SQL

ArcGIS Server Services• Mapping– Base– BaseM– SOR– Schools– AerialPhoto*– Contours*

• Geocoding– Point Locator

Cached Services• Aerial Photo

– 10 cache levels– 1:600 & doubling up to 1:307200– JPEG, 75% compression & 512 x 512– 14GB on disk for approx. 775 sq miles– At least 16 hours to create

• Contours– 4 cache levels– 1:600 & doubling up to 1:4800– PNG, 512 x 512 & anti-aliased– 3GB on disk for approx. 775 sq miles– 5 plus hours to create

• Polygon shapefile used for cache extent

ArcGIS Server Applications

• Using Freeance Web/Mobile 3rd party software– Internal/Public App– Sex Offender Registry App– School Attendance Areas App– BlackBerry Mapping App

Items we’ve run into

• Security for both server and services

• Freeance does not support many to one apps

• Redo the post-install after server url was assigned

• ESRI’s vision for AGS still doesn’t mesh with what our county needs for web mapping

Where we want to go…

• Future versions– Create child service groups– Create representations for base layers– Continue to improve the cartographic look– Build application w/out cascading services– Add a layer for hillshade relief

• Look into building our own application– Java based?

• Leverage the new .msd file type in 9.3.1?

Discussion Topics

• What layers do you plan on caching?• How many cache levels are you going

to use?• How many layer group levels to use?• Building internally, or purchasing 3rd

party?• Project templates for sharing?• Application templates for sharing?• Balance between novice and power

users?
