ARCSDE & ARCIMSMr. David A. Perini

ARCIMS Internet Mapping Server

Distribute GIS information over the Internet

Integrates with addition ESRI software ArcSDE, ArcGIS, ArcInfo, ArcMap etc…

Available Extensions Route map enables routing ($) Site starters (free)

Written in ASP (active server pages)

How do I install it? For IIS need to run Java Servlets

Tomcat(free) ServletExec by New atlanta($)

Can be very difficult. Install is a learning experience Need administrative privileges ESRI install documentation poor ESRI’s user forums are excellent.

Three Parts of ARCIMS Administrator- Used to manage ArcIMS

Service is equivalent to a “virtual directory” in IIS AXL or MXD can be turned into a Service

WARNING MXD’s as a service do not work often

Author- Used to design ARCIMS services Similar to ArcGIS Add data to AXL project

Designer Create sites in IIS server

Administrator Start Stop Services

Can stop individual services Add New service Launch Author/Designer Can Manage Multiple Servers

Three types of Services Feature- TRUE GIS on web Image- Images of maps Metadata- Share GIS Metadata

MetaData in IMS? Data about the data

Use GIS data more efficiently

Metadata Explorer Included with ARCIMS

Designer

Very limited version of ARCGIS Design contents of a Service

If you can use ARCGIS 8.x you will have no trouble producing AXL files for use with IMS.

DATA allowed Coverage Shape SDE data connection

Can mix and match data sources in one Project Warning -Not recommended

Works “sometimes”

Author Wizard

Create new site under IIS www.us.com/Ims/index.html

HTML or Java Viewer? HTML works always Java doesn't work well with IE

HTML browser is very good

Note: Geomedia’s (Intergraph) has ActiveX plug-in that works better with IE. –Competitor to IMS

How can I customize IMS? Extensions

RouteMap (for routing) Site starters

Written in ASP Fairly easy to customize Multiple free ones available

ActiveX connector Tough to program but very versatile

For advanced users Used to add IMS to other web site

JavaScript to directly customize IMS

Part 2 :ArcSDE ArcSDE

Spatial Database Engine STORE GEOGRAPHIC DATA STORE GEOGRAPHIC DATA

IN A RELATIONAL IN A RELATIONAL DATABASE!DATABASE!

Transparent to user that data is Transparent to user that data is in database.in database.

Uses GIS Gateway to relational

databases Also can be used to manage

data in databases Insert/ Delete etc…

What databases can I use? Oracle SQL Server DB2 Informix Spatial extension for DB2 AND Oracle also

work with SDE

How do I install it? Latest version is 8.2.

Big jumps between 8.x revisions so use current Wizard is very good

Create user, database etc on SQL server easily. Program has no GUI.

Command line OR ARCGIS to manipulate database

Database considerations One or many databases

One database is easy to administer.

Use many if you have lots of

different data have lots of different

users of the data.

Privileges Privileges SDE is VERY particular about permissions

SDE user(s) MUST have some high level database permissions to work.

If all else fails use administrator and take privileges away until you find the failure.

Documentation on this is short but specific

See configuration tuning guides-

TUNING SDE TUNING IS NOT OPTIONAL Big guides for each DBMS

Small adjustments can yield 25% speed improvements with SDE

SDE is STILL slow with LARGE coverage's (over 300meg)

DO NOT log more then a few users with same username. Read write log file is the same file Imagine having 20 people read

write to same text file @ same time.

Connecting IN ARC CATALOG Database connection>Add spatial

database Connection

User must have correct permissions Server :ltl6 < our SDE server Service: Port # 5151 default Database (optional) Account info

TEST first Now you can READ from the data.

EDITING data in SDE database Must be versioned

In Arc Catalog Open list of shapes in database Select a record (shape, coverage) Right click and set register as versioned

What is versioning? Stores a backup while you edit so more then one

person can edit same record at the same time.

IT DOESN’T WORK Common issues with ESRI software

There are BIG steps between 8.x and 8.2 Make sure you use all the latest stuff ARCIMS 4.X will ONLY work with ArcSDE 8.2

ArcGIS 8.X must line up with your 8.x of SDE or you could be in for trouble

Next step is to check file/user permissions After that check ESRI user forum Next try and call a friend Call ESRI- don’t bother e-mailing them
