This page contains answers to common questions handled by our support staff, along with some tips and tricks that we have found useful and presented here as questions.

Note: In these answers we will follow a few shorthand conventions for describing user-interface procedures. Key combinations will be presented like this: Ctrl+Alt+Delete, which means that you should press and hold down the Control key, the Alt key, and the Delete key at the same time. Menu selections will be presented like this: File->Open, which means that you should open the File menu, and then make the Open selection.

How users are notified about new releases?

If you are using version 2.0 or later, then the LiveUpdate mechanism built-in your software will automatically tell you next time you execute the software if an update is necessary. If so, select the LiveUpdate icon on the GeoWorlds program folder and all appropriate files will be automatically downloaded to your system. The changes will be effective next time you start GeoWorlds.

If you are still using version 1.0, then you should check the "What's New" page on this web site for new information about major releases, bug fixes and documentation updates. Also, we strongly advise you to upgrade to version 2.0. 

Please, don't forget to register as GeoWorlds user. You just need to send us your name and email address. That's all!

Do I need to login to the server to work with GeoWorlds?

No. You can choose to work either on standalone or client/server modes. On the standalone mode, all your working files and information spaces are saved on your local machine, whereas on the client/server mode, all files are saved on the clipbook. The clipbook in this case is used as a common repository that let users share information whenever they are working on the client/server mode. Note however, that there is no way to export your local files to the clipbook. Therefore, we strongly recommend working on the client/server mode as often as possible if you are part of a team.

Do I need to be connected to the internet to work with GeoWorlds?

Yes. Most of the features and services such as downloading map information from the gazetteer, querying the web, and accessing  the clipbook require access to the internet.

Can I install GeoWorlds on a Windows 95/98 machine?

Not at this point. We are planning to port GeoWorlds to Windows 98, but this has been a low priority task compared with the otehr commits we have so far. Moreover, all our customers and beta testers use Windows NT machines.

Does GeoWorlds work on a UNIX machine?

No. See previous answer.

Why a session is labeled as "incident"?

There is a historical reason for naming the sessions as Incidents. Most of the early work was performed using a disaster relief scenario in which emergency operation teams login to one of the available incidents to work as a group, sharing document and map information. Since then, we have kept Incident as the term referring to a map-document situational analysis.

What is the difference between a map and a map layer in ArcView?

As far as the user is concerned, a map is the background image displayed on ArcView, whereas a map layer is the layered information about the region itself, such as demographic information, street names, vegetation, and so on.

As far as the internal implementation is concerned, there are no differences between a map and a map layer since they share the same internal representation. This makes it very easy to add new layers and/or maps to our existing gazetteer.

Do I need to have ArcView installed in my machine?

You only need to have ArcView installed in your system in case you are planning to take adfvantage of GeoWorlds mapping capabilities. All system features and services that do not depend or interface with the Mapping Manager work  well with or without ArcView installed in your system.

Can I work only with the Information Manager?

Yes. Users can work only with the information manager without having to worry about the Mapping or Incident managers. GeoWorlds automatically creates a default incident session for you if you work only with the Information Manager. This is necessary in case you decide to interface with either the Map or Incident managers.
