Mapping software with tools for data management and professional map editing.

Wersja polska

A database holds vector graphics data and attribute data. Map contents is generated from database and can be further edited at will.

Supports choropleth and related aeral presentations; linear, point and label presentations, as well as pie and bar cartodiagrams. Range-based presentations can display one or two variables simultaneously. Diagrams can display unlimited number of variables.

Graphics style can be applied to whole layers, layer ranges or individual objects. Objects can be re-shaped and re-positioned, new objects can be added.

Maps from different sources can be overlayed or tiled, thanks to uniform geographical coordinates. Map projection is transparently applied "on the fly".

Raster image (e.g. scan) can be included and perfectly fit to vector contents.

	Statistical, census, population and electional mapping
	Cartographic visualisation for environment research including geology, geomorphology, soils, botany, and other fields
	Business and economic data visualisation
	Decision support for spatial planning and zoning
	Topographic map production

The range of possible applications is as wide as map usage itself. Adventages of GIS over ingenuous "map drawing" are most apparent when datasets are large or change frequently.

System 4, running under 32-bit Windows is a successor to the line of programs running on 16-bit Windows platform. The whole project took several years to complete.

New system was developed from scratch and features much wider functionality and new philosophy. Special attention was paid to flexible connection between map and database and to comfortable user interface. There was good reason for this: AVISO become a major workhorse for the development of 1:200.000 Digital Map of Poland and two related Reader's Digest Auto Atlases.

Supporting several critical projects since 2001, system 4 proved its reliability and cost-effectiveness compared to off-the-shelf GIS software.

Features that may be of interest to advanced GIS users.

è Effective digitizing tools, including simultaneous multiple layer editing, vector tracing and semi-automatic raster tracing.

è Intelligent handling of links between map and database. Users are allowed to modify map and data tables independently. Synchronization procedure updates map with new data without loosing manual changes.

è Raster images of unknown projections may be registered without raster transformation.

è Carbon copy layers clone other layer's contents with different graphics style. Sophisticated effects may be produced without object duplication and maintenance.

è Updateable dynamic SQL queries.

è Data import and export from/to MapInfo and ESRI systems.

• AVISO maps directly supported by AIMS (Aviso Internet Map Server)

• Gazetteer data export to AIMS

• GeoTIFF (georeferenced raster) export.

• Vector-based, device-independent area fills.

• New SQL function for object topology testing.

• Wheel mouse support for map navigation.

• Multipoint objects.

• New projections and support for ellipsoid-based earth model.

è Reference in Polish (you may at least enjoy pictures, provided you have Internet Explorer).
