GIS ObjectLand is a universal Geographic Information System for Windows.Key features:- creation of vector-raster maps with arbitrary structure of layers and feature types in an internal ObjectLand database or in following DBMSs - MS SQL Server, Oracle, DB2, MySQL, Interbase/Firebird, PostgreSQL, MS Access;- creation of themes. Theme is a user presentation of a map;- control of displaying features depending on the chosen scale;- spatial data input and editing by assigning feature coordinates and also by interactive drawing with mouse or digitizer;- sewing of separate pages of an imported map into one unified continuous map;- copying, merging, and moving maps, layers, and feature types between different geoinformation databases;- creation of tables of arbitrary structure;- creation of queries. Query is a user presentation of table built by setting search and sorting conditions, joining tables, calculations and using reference tables;- copying, merging, and moving tables and queries between different geoinformation databases;- setting arbitrary links between spatial and table information;- getting information about the feature selected on the map;- searching for features on the map by linked records;- creation of filters. Filter is conditions of feature visualization depending on spatial properties of features and linked table data;- creation of layouts. Layout is an output form combining spatial, table information and presentation elements;- import and export of table and spatial information for widespread data formats;- support of style libraries containing fonts, map symbols, line styles, hatches and fill styles;- style editors for displaying styles;- setting for users the access permissions to components;- multiuser data editing;- using and editing tables of external database (via ODBC) as linked tables;- providing automation COM interfaces for user applications.
