Designed for engineers with planning and mapping needs, MicroStation GeoGraphics fully integrates CAD and GIS technologies. The system extends MicroStation 95 to provide computer-aided design with a full-featured GIS. It can function on a stand-alone PC or as part of a workgroup. Microstation GeoGraphics is built on open GIS standards -- users can extend system capabilities and create customized applications on different platforms and operating systems.
Features include an integrated Web browser, URL support, and 2D/3D Web publishing tools for accessing Web-based geoengineering data and establishing links between map features and Web pages. A new suite of GIS translators enables users to read and write other industry-standard GIS formats from within MicroStation GeoGraphics.
Users can input, manage, and output vector- and raster-based data, and access individual maps by point-and-click. They can also correct geometric problems using a suite of clean-up and validation tools. An "undo" command allows any clean-up operation to be rolled back when tolerance settings produce undesirable results.
An interactive query builder helps users create database queries and locate associated map features across map databases. Feature-association tools allow application of feature definitions to all elements in a file in one pass. With on-demand topology tools, users can create virtual topology layers containing point, line and polygon data, and use spatial analysis to determine spatial relationships between data layers. MicroStation GeoGraphics can also import and export a wide range of imagery -- airborne, satellite, scanned maps and drawings. Maps can be created using data-driven thematic tools.
MicroStation GeoGraphics supports most commercial databases -- Oracle, Informix, Microsoft Access, Microsoft SQL Server and Intergraph RIS -- and is available on all platforms supported by MicroStation 95.

ArcView GIS 3.0
ArcView 3.0 core features include an intuitive, Windows-based graphical user interface that is easy to use -- many libraries and city halls have installed ArcView for public use. Geocoding and address-matching features let users create maps of any relational data with geographic components to profile and visualize relationships. They can also directly access all types of geographic data for display, spatial analysis and map production. ArcView can be used alone or in network applications. It works particularly well as a client to ESRI's spatial database engine -- a universal, geodata server that can be customized for use by non-technical types. A key feature is ArcView's extensible architecture, which provides a foundation for third-party applications, building extensions that expand GIS functionalities to provide solutions to more complex applications.
Since our last review, ESRI has developed eight new extensions:
ArcView Internet Map Server
Designed for publishing geographic databases and mapping applications in a standard Internet/intranet environment, Map Server works with all data types supported by ArcView, including raster, vector and geographic databases, and tabular data sets. End users can explore maps using any HTML browser that supports Java. No additional software is required to view or download maps. Web site developers can use Map Server to add intuitive and visual dimensions to live maps at Web sites. End users
